In modern industrial production, the dust-free workshop plays a crucial role. The selection of building materials not only affects the performance and quality of the workshop but also directly impacts the construction cost. As a professional manufacturer, Guangzhou Cleanroom Construction Co., Ltd. provides you with an in-depth analysis of the key points in the selection of building materials for the dust-free workshop and the cost control scheme. I. Key Points in the Selection of Building Materials for the Dust-Free Workshop (I) Wall Materials   Performance Requirements The walls of the dust-free workshop need to have good flatness and smoothness to reduce dust accumulation. At the same time, they should have a certain degree of strength and stability to withstand the impact during equipment installation and daily use. In addition, the fireproof, moisture-proof, and antibacterial properties of the wall materials are also key considerations. Analysis of Commonly Used Materials Color Steel Plate: It is easy to install and has an elegant appearance. Its surface is flat and smooth, easy to clean, and can effectively meet the cleanliness requirements of the dust-free workshop. Moreover, the color steel plate is available in a variety of colors and can be matched according to the overall style of the workshop. However, the sound insulation effect of the color steel plate is relatively average, and additional sound insulation measures may be required in workshops with high noise control requirements. Magnesium Oxide Board: It has excellent fireproof performance, reaching the A-class non-combustible standard, which has obvious advantages in some industries with extremely high fire safety requirements, such as electronics and chemical industries. At the same time, the magnesium oxide board also has good moisture-proof and antibacterial properties and a long service life. However, its texture is relatively brittle, and special care should be taken during handling and installation to avoid damage. (II) Floor Materials   Performance Requirements The floor of the dust-free workshop should have high strength and wear resistance to withstand frequent personnel movement and equipment transportation. Good antistatic performance can prevent static electricity from damaging electronic equipment. In addition, the floor needs to have good sealing performance to prevent dust from entering the workshop through floor gaps. Analysis of Commonly Used Materials Epoxy Self-Leveling Floor: It has high flatness and seamless connection, which can effectively avoid dust accumulation. Its surface is hard and wear-resistant, and has excellent chemical corrosion resistance, suitable for a variety of industrial environments. Moreover, the epoxy self-leveling floor is available in a variety of colors and can be used for color marking in different workshop areas for easy management. However, the construction process of the epoxy self-leveling floor is relatively demanding, and problems such as bubbling and cracking are prone to occur if the construction is improper. PVC Floor: It has good flexibility, comfortable foot feel, and a certain sound absorption effect, which can provide a relatively quiet working environment for workshop staff. The installation of PVC floor is simple and fast, and the price is relatively affordable. However, its wear resistance and high temperature resistance are relatively weak, and it is not suitable for workshops with frequent operation of heavy equipment or high-temperature operations. (III) Ceiling Materials   Performance Requirements The ceiling material should be lightweight and high-strength for easy installation and maintenance. Good airtightness can prevent air leakage and ensure the cleanliness of the workshop. At the same time, the ceiling material needs to have a certain thermal insulation performance to help maintain the temperature stability in the workshop. Analysis of Commonly Used Materials Aluminum Alloy Microporous Plate: It is lightweight, high-strength, and easy to install. Its microporous structure can effectively filter dust particles in the air and ensure the air quality in the workshop. The aluminum alloy material has good corrosion resistance and a long service life. However, the price of the aluminum alloy microporous plate is relatively high, and the initial investment cost is large. Gypsum Board: It is low-cost and has a certain fireproof performance. The surface of the gypsum board is flat and can be painted or decorated to meet the aesthetic needs of different workshops. However, the moisture-proof performance of the gypsum board is relatively poor, and it is prone to deformation and mildew in a humid environment, requiring enhanced moisture-proof measures. II. Cost Control Scheme for the Construction of the Dust-Free Workshop (I) Cost Control in the Design Stage   Reasonable Planning and Layout According to the production process and equipment requirements, optimize the layout of the workshop to reduce unnecessary space waste. Reasonably determine the area and location of each functional area to avoid material waste and increased construction difficulty caused by unreasonable layout. For example, placing equipment that generates more dust in the area close to the dust removal system can shorten the length of the ventilation duct and reduce costs. Accurate Calculation of Material Consumption In the design stage, accurately calculate the consumption of various building materials to avoid excessive or insufficient material procurement. This requires designers to have an accurate grasp of the workshop structure and size and make a reasonable estimate in combination with the construction process. At the same time, consider the material loss rate and reserve a certain margin, but avoid excessive margins that cause waste. (II) Cost Control in Material Procurement   Multi-Channel Comparison and Procurement Establish a wide range of supplier networks and compare the prices, qualities, and delivery times of different suppliers through inquiries and tenders. Select suppliers with high cost performance to cooperate with and strive for the most favorable procurement price while ensuring the quality of materials. For example, for the commonly used color steel plates for walls, you can consult the prices of multiple manufacturers and distributors, compare the differences in product specifications, materials, and after-sales services, and choose the most suitable supplier. Utilization of the Advantage of Bulk Procurement According to the scale of workshop construction, reasonably determine the bulk procurement of materials. For materials with large consumption, such as epoxy self-leveling materials for the floor and aluminum alloy microporous plates for the ceiling, negotiate with suppliers to obtain bulk purchase discounts. Bulk procurement can not only reduce the unit price of materials but also reduce the number of procurement times, lowering the procurement cost and transportation cost. (III) Cost Control in the Construction Process   Optimization of the Construction Process Select mature and efficient construction processes to improve construction efficiency and shorten the construction period. Reasonably arrange the construction sequence to avoid repeated construction and material waste caused by cross-operation. For example, during the construction of the wall and floor, the ground base treatment can be carried out first. After the ground is dry, the wall installation can be carried out, and finally the floor surface construction can be carried out. This can avoid the pollution and damage to the ground caused by the wall construction and reduce the repair cost. Strengthening of Construction Management Strictly control the construction quality to avoid rework and material waste caused by quality problems. Establish a sound construction management system, strengthen the training and management of construction personnel, and improve the technical level and sense of responsibility of construction personnel. For example, during the installation of the color steel plate on the wall, require construction personnel to install it in strict accordance with the operating procedures to ensure that the plate joints are tight and flat, avoiding air and dust leakage problems caused by improper joint treatment, thereby reducing the later maintenance cost. (IV) Consideration of Operation and Maintenance Costs   Selection of Durable Materials In the material selection stage, fully consider the service life and maintenance cost of materials. Select building materials with reliable quality and good durability. Although the initial investment may be higher, it can reduce the high cost caused by frequent material replacement in the later stage. For example, although the aluminum alloy microporous plate ceiling is more expensive, it has a long service life and simple maintenance, and is more cost-effective in the long run. Reservation of Maintenance Channels and Spaces In the workshop design, reasonably reserve maintenance channels and spaces to facilitate the daily maintenance, inspection, and replacement of equipment and building materials. This can improve the efficiency of maintenance work and reduce maintenance costs. For example, when designing the ceiling, consider setting removable access openings to facilitate the maintenance of the ventilation system and lighting equipment inside the ceiling, avoiding additional costs caused by inconvenient maintenance.   The selection of building materials and cost control for the dust-free workshop is a systematic project that requires comprehensive consideration of multiple factors. Guangzhou Cleanroom Construction Co., Ltd., with rich industry experience and professional technology, can provide you with a comprehensive solution to help you build a dust-free workshop with excellent performance and reasonable cost and assist enterprises in efficient production.

In the field of purification projects, purification boards are key materials for constructing clean spaces. The stability of their installation on standing walls directly affects the performance and quality of the entire clean space. As a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd. will now provide you with a detailed analysis of the key points and steps for fixing purification boards on standing walls. I. Pre - installation Preparation   Material Verification Ensure that the specifications and models of the purification boards meet the design requirements. The surface of the boards should be free from damage and deformation, and the performance indicators of the core materials, such as fire resistance, moisture resistance, and thermal insulation, should reach the standard. At the same time, prepare the matching fixing parts, such as aluminum alloy profiles, self - tapping screws, sealants, etc. These fixing parts must have good corrosion - resistance to adapt to the purification environment. Wall Base Treatment The base of the standing wall must be flat and solid, with the error controlled within a very small range. Clean the wall to remove impurities such as dust and oil stains. If there are uneven areas, use materials such as cement mortar to level them, providing a reliable reference surface for the installation of purification boards. II. Installation of the Framework   Generally, aluminum alloy profiles are used to build the framework. Cut the profiles according to the size of the standing wall and assemble them. The verticality and flatness of the framework should be strictly controlled. Use tools such as levels and theodolites to check and verify repeatedly to ensure that the error does not exceed the specified value. The connection parts of the framework should be tight and firm. Angle codes can be used for connection and riveting or bolt fastening to form a stable support structure, which is the basic support for the fixation of purification boards. III. Installation and Fixation of Purification Boards   Installation of the Starting Board Start installing the starting purification board from the corner of the wall. Align one side of the board with the framework and use self - tapping screws to fix the board on the aluminum alloy profile. The screw spacing should be uniform, usually one screw every 200 - 300mm along the edge of the board. The screws should be tightened to make the board fit closely to the framework, but be careful not to over - tighten and damage the board. Splicing and Fixing of Subsequent Boards Subsequent purification boards are spliced in sequence. The adjacent boards are connected by tongue - and - groove joints. This connection method not only ensures the airtightness of the wall but also facilitates installation and positioning. At the same time of splicing, fix them with self - tapping screws to ensure that each board is firmly installed on the framework. For purification projects with requirements for thermal insulation and sound insulation, sealant should be filled in the board joints to prevent air and dust leakage and enhance the overall airtightness. IV. Detail Strengthening Treatment   Treatment of Wall Corners and Door and Window Openings Special corner profiles are used to wrap the wall corners, making the splicing of purification boards transition naturally, beautifully, and with good airtightness. Around the door and window openings, the purification boards need to be precisely cut, and the matching edge - closing profiles are installed and reinforced with screws to ensure the strength of the edge of the opening and meet the installation requirements of doors and windows. Overall Inspection and Adjustment After all the purification boards are installed, conduct a comprehensive inspection of the entire standing wall. Check whether the board surface is flat and whether there is any misalignment; gently push the boards by hand to check whether they are firmly fixed; repair the sealant where it is unevenly applied or there are gaps to ensure that the overall quality of the purification wall meets high standards and create a solid and reliable enclosure structure for the purification project.   With exquisite craftsmanship and rich experience, Guangzhou Cleanroom Construction Co., Ltd. keeps improving in the production of purification boards and the implementation of purification projects.

In chemical laboratories, which are at the forefront of scientific research exploration and teaching practice, a wide variety of wastewater with complex compositions is generated every day. If this wastewater is discharged directly without proper treatment, it will cause incalculable harm to the environment. As Guangzhou Cleanroom Construction Co., Ltd., a professional manufacturer specializing in the purification field, today we will take you to have an in-depth understanding of the process standards for chemical laboratory wastewater treatment. I. Analysis of the Sources and Hazards of Wastewater   The wastewater in chemical laboratories mainly comes from the discharge of waste liquid after various chemical reactions, the water used for cleaning instruments and equipment, and the discarded liquid generated during sample pretreatment. Its components include heavy metal ions such as mercury, cadmium, and lead. These heavy metals are highly bio-toxic and will accumulate through the food chain after entering the water body, ultimately threatening human health. There are also organic pollutants, such as various organic solvents, phenols, and aldehyde compounds. They are difficult to degrade and will pollute the soil and water for a long time, destroying the ecological balance. In addition, acid-base substances, if discharged in excess, will change the pH value of the water body, causing aquatic organisms to lose their suitable living environment. II. Pretreatment: The Key Beginning of Wastewater Treatment   Classification and Collection This is the foundation of pretreatment. According to the composition and properties of the wastewater, it is divided into different categories such as organic wastewater, inorganic wastewater, and heavy metal wastewater. For example, chromium-containing wastewater should be collected separately because its subsequent treatment method is completely different from that of ordinary acid-base wastewater. Classification and collection can effectively prevent the mixture of wastewater with different components from generating more complex and difficult-to-treat substances, laying a solid foundation for subsequent precise treatment. pH Adjustment The pH value of most chemical laboratory wastewater fluctuates greatly. Use acid-base neutralizing agents to adjust the pH value of the wastewater to a range suitable for subsequent treatment, generally between 6 and 9. This can not only prevent strongly acidic or strongly alkaline wastewater from corroding treatment equipment but also enable some heavy metal ions to form precipitates under specific pH conditions, preliminarily removing some pollutants. III. The Core Treatment Stage: Tackling Pollution from Multiple Aspects   Coagulation and Sedimentation Add coagulants such as polyaluminum chloride and ferrous sulfate to the wastewater. The colloidal particles formed after the hydrolysis of the coagulants can adsorb the fine suspended particles, colloids, and some dissolved organic substances in the wastewater. Through the processes of coagulation and flocculation, they gather into larger flocs and settle down, taking away a large number of impurities and effectively reducing the turbidity of the wastewater and the content of some organic pollutants. Oxidation-Reduction Treatment For pollutants with oxidizing or reducing properties in the wastewater, corresponding oxidation-reduction methods are adopted. For example, for cyanide-containing wastewater, oxidants such as sodium hypochlorite are added to oxidize the highly toxic cyanide ions into non-toxic nitrogen gas and carbon dioxide for discharge. For wastewater containing heavy metal ions such as hexavalent chromium, reducing agents such as ferrous sulfate are used to reduce them to trivalent chromium, which is easier to remove during the subsequent sedimentation process, greatly reducing the risk of heavy metal pollution. Advanced Filtration After the wastewater has been treated through the previous steps, there may still be a small amount of fine particles and incompletely settled colloids remaining. At this time, advanced filtration technologies such as ultrafiltration and reverse osmosis are adopted. The ultrafiltration membrane can intercept macromolecular organic substances and colloids, while the reverse osmosis membrane, with its extremely small pore size, can block almost all dissolved salts and heavy metal ions, further purifying the wastewater so that it approaches or meets the discharge standards. IV. Post-treatment and Monitoring: Ensuring Discharge up to Standards   Disinfection Treatment Before the treated wastewater is discharged, it needs to be disinfected to kill the pathogenic microorganisms it may carry. Commonly used disinfection methods include ultraviolet disinfection and chlorine dioxide disinfection. Ultraviolet light inactivates microorganisms by destroying their DNA structure, while chlorine dioxide relies on its strong oxidizing property to oxidize the key enzymes in microorganisms, ensuring that the wastewater will not cause public health problems after discharge. Compliance Monitoring A strict monitoring system should be established. According to the relevant national discharge standards, key indicators such as COD (Chemical Oxygen Demand), BOD (Biochemical Oxygen Demand), heavy metal content, and pH value of the treated wastewater should be regularly tested. Only when all indicators meet the standards can the wastewater be safely discharged. This is the last line of defense for environmental protection.   As a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd. has developed and produced a series of professional equipment suitable for chemical laboratory wastewater treatment based on these strict process standards. Our equipment is integrated with an advanced automatic control system, which can accurately regulate each treatment link and efficiently and stably purify laboratory wastewater, helping laboratories achieve green development.   If you have any questions about chemical laboratory wastewater treatment or want to learn more about purification solutions, please feel free to contact us. Let's work together to safeguard the cleanliness of laboratories and the health of the environment.  

In today's era of rapid technological development, the field of optical microelectronics is driving the transformation of various industries at an unprecedented pace. Behind all these brilliant achievements, the optical microelectronics cleanroom technology plays a vital role. As Guangzhou Cleanroom Construction Co., Ltd., a manufacturer specializing in the production of purification equipment, today we will take you to briefly analyze this key technology.   I. The Importance of Optical Microelectronics Cleanrooms   During the manufacturing process of optical microelectronics, even the tiniest dust particles, microorganisms or chemical contaminants can have a fatal impact on precision optical components and microelectronics chips. For example, a dust particle with a diameter of only a few micrometers falling on the key circuit parts of a chip may lead to faults such as short circuits or open circuits, rendering the entire chip useless. Cleanrooms are like the "sterile delivery rooms" for these high-tech products, creating a nearly perfect production environment for them and ensuring a high yield rate and stability of the products to meet the stringent quality requirements of the optical microelectronics industry.   II. Key Technical Points   Air Purification System This is the "heart" of the cleanroom. High-efficiency particulate air (HEPA) filters and ultra-low penetration air (ULPA) filters are the key components. They can filter out the vast majority of dust particles in the air. For particulate matter with a particle size of 0.3 micrometers or even smaller, the filtration efficiency can reach 99.97% or higher. Combined with a reasonable air distribution design, such as laminar flow and turbulent flow designs, the clean air can evenly and stably cover the entire workshop, continuously removing possible contaminants and maintaining the cleanliness level in the workshop. Temperature and Humidity Control The production of optical microelectronics is very sensitive to the environmental temperature and humidity. If the temperature is too high or too low, the materials will expand or contract due to heat, affecting the precision of components. If the humidity is too high, it is easy to cause rust on metal parts and short circuits of electronic components due to moisture. If the humidity is too low, static electricity will be generated, attracting dust. Through precise air-conditioning systems and humidification and dehumidification equipment, the temperature in the workshop can be accurately controlled within a fluctuation range of ±1 °C or even smaller, and the humidity can be maintained in the appropriate range of 40% - 60%, creating stable temperature and humidity conditions for production. Static Electricity Prevention and Control In microelectronics processing, static electricity is like an "invisible killer". The high voltage generated instantaneously by electrostatic discharge (ESD) can easily break through the insulating layer of chips and damage electronic devices. Cleanrooms adopt multiple means such as grounding systems, static eliminators and anti-static materials to eliminate the hidden dangers of static electricity generation from all aspects such as people, equipment and materials, ensuring the safety of production in an all-round way.   III. Advantages and Innovations of Guangzhou Cleanroom Construction Co., Ltd.   As a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd. has been deeply involved in the field of optical microelectronics cleanroom technology for many years. Our independently developed purification equipment not only strictly complies with the high international standards for cleanliness but also has unique features in terms of energy conservation and consumption reduction and intelligent operation and maintenance.

In today's high-tech industries, such as electronics, semiconductors, and pharmaceuticals, the environmental quality of clean rooms is of vital importance. And the issue of static electricity, as a potential risk factor, can have a serious impact on product quality and the production process. Guangzhou Cleanroom Construction Co., Ltd., as a professional manufacturer of purification equipment, will now provide you with an in-depth interpretation of the principle of electrostatic discharge protection (ESD) in clean rooms. Generation of Static Electricity   In clean rooms, static electricity can be generated in various ways. Human activities are one of the common sources of static electricity. For example, when people walk, operate equipment, or put on or take off work clothes, the friction between the body and clothes, the floor and other objects can cause charge separation and accumulation, thus generating static electricity. In addition, the operation of equipment can also cause static electricity. For instance, the friction between high-speed rotating mechanical parts and the electric field induction of electrical equipment can lead to static electricity. Even the friction between the air flow and the surface of objects, as well as the mutual friction of raw materials during handling and processing, may result in the generation of static electricity. Hazards of Static Electricity to Clean Rooms   For the electronics and semiconductor industries, static electricity may cause breakdown and damage to electronic components, resulting in a decline in product performance or even complete failure. During the chip manufacturing process, a tiny electrostatic discharge may damage the precise circuit structure inside the chip, rendering the entire chip useless and bringing huge economic losses to enterprises. In the pharmaceutical industry, static electricity may adsorb dust and microorganisms, contaminating pharmaceuticals and affecting their quality and safety. Meanwhile, static electricity may also trigger dangerous situations such as fires or explosions. Especially in clean rooms where flammable and explosive substances are present, the energy generated by electrostatic discharge is sufficient to ignite these substances, endangering the lives and property of personnel. Principle of Electrostatic Discharge Protection (ESD)     Grounding Grounding is one of the most basic and effective methods for eliminating static electricity. By connecting equipment, workbenches, personnel, etc. to the earth, the accumulated charges can be quickly drained away, thus avoiding the accumulation and discharge of static electricity. In clean rooms, a special anti-static grounding system is usually laid to ensure that all objects that may generate static electricity can be reliably grounded. For example, the shells of equipment on the electronics production line and operating tools should be connected to the grounding electrode through grounding wires to release electrostatic charges to the earth in a timely manner, maintaining the potential on the surface of objects at zero and preventing static electricity from damaging electronic components.     Electrostatic Neutralization When static electricity cannot be completely eliminated by grounding, electrostatic neutralization technology comes into play. This method uses electrostatic eliminators to generate ions with the opposite polarity to that of the charged object, so that the electrostatic charges are neutralized. Electrostatic eliminators ionize the air through a high-voltage power supply, generating a large number of positive and negative ions. These ions will actively adsorb onto the object with static electricity and offset the charges on the object, thereby achieving the purpose of eliminating static electricity. In some clean room areas with extremely high sensitivity to static electricity, such as chip packaging workshops, multiple electrostatic eliminators will be installed to ensure that the ion concentration in the air can neutralize the generated static electricity in a timely manner and protect products from electrostatic hazards.     Humidity Control Properly increasing the humidity in clean rooms can effectively reduce the generation of static electricity. This is because in a high-humidity environment, a thin layer of water molecules will be adsorbed on the surface of objects. Water molecules are conductive and can make it easier for charges to conduct and leak on the surface of objects, thus reducing the accumulation of static electricity. Generally speaking, it is more appropriate to control the relative humidity in clean rooms between 40% and 60%. However, it should be noted that the control of humidity also needs to be adjusted according to specific production processes and product requirements, because excessive humidity may have an adverse impact on some products or equipment, such as causing rust on metal parts and affecting the performance of electronic equipment.     Use of Anti-Static Materials In clean rooms, selecting anti-static materials to make equipment, tools, work clothes, and packaging materials can reduce the generation of static electricity at the source. Anti-static materials have good electrical conductivity or electrostatic dissipation properties, enabling charges to conduct and release rapidly within the materials and avoid charge accumulation. For example, anti-static work clothes are made of fabrics containing conductive fibers. When people wear these work clothes and move around, the electrostatic charges generated can be quickly drained away through the conductive fibers, preventing static electricity from affecting the surrounding environment and products. Similarly, anti-static workbench mats, turnover boxes, etc. also reduce the risk of static electricity generation by using special anti-static materials.     In conclusion, understanding the principle of electrostatic discharge protection (ESD) in clean rooms and taking effective electrostatic protection measures are crucial for ensuring product quality, improving production efficiency, and ensuring the safety of personnel and equipment. Guangzhou Cleanroom Construction Co., Ltd., with its professional technology and rich experience, can provide a full range of electrostatic protection solutions for various clean rooms, helping enterprises create a safe, stable, and efficient production environment.   If you are interested in electrostatic protection in clean rooms or other issues related to purification equipment, please feel free to contact us.

In the pharmaceutical industry, clean compressed air, as a crucial process gas, directly affects the quality and safety of pharmaceuticals. As a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd. fully understands its importance. Today, we will introduce in detail the daily monitoring and standards of clean compressed air in pharmaceutical clean rooms. Why Is Strict Monitoring of Clean Compressed Air Necessary?   During the pharmaceutical manufacturing process, compressed air is widely used in multiple aspects such as material transportation, equipment driving, and fermentation cultivation. If the compressed air contains impurities like dust particles, microorganisms, moisture, and oil, it may contaminate pharmaceuticals, affecting their purity, stability, and effectiveness. In severe cases, it may even lead to substandard pharmaceutical products and endanger the health of patients. Therefore, daily monitoring of clean compressed air is an essential measure to ensure that pharmaceutical production complies with regulations and quality requirements. Key Parameters for Daily Monitoring     Particle Counting: This is one of the important indicators for measuring the cleanliness of compressed air. Through professional dust particle counters, the number of particles within different particle size ranges can be detected. Usually, attention is paid to the number of particles with particle sizes such as 0.1μm, 0.2μm, 0.5μm, 1.0μm, and 5.0μm. Different areas in pharmaceutical clean rooms have strict limitations on particle counting according to their cleanliness level requirements. For example, in the Grade A clean area, the allowable number of tiny particles is extremely low, which requires that the particle count of the compressed air must be maintained at an extremely low level to prevent particles from contaminating the pharmaceutical production process.     Microbial Content: Microbial contamination is a significant risk in pharmaceutical production. Microorganisms in compressed air may come from the air source, inside the compression system, or the pipeline system. By using appropriate microbial samplers and culturing methods, the number of bacteria, fungi, and other microorganisms in the compressed air can be detected. Pharmaceutical workshops usually require that the microbial content in compressed air meets strict standards, generally measured by the number of colony-forming units (CFU) per cubic meter of air, ensuring that it is within a safe range to prevent microorganisms from breeding and spreading during the pharmaceutical production process and thus affecting the quality of pharmaceuticals.     Moisture Content: Moisture in compressed air may cause pipeline corrosion, microorganism growth, and may also have an adverse impact on pharmaceutical quality in certain pharmaceutical processes. Commonly used moisture detection methods include dew point meter for measuring dew point temperature and electrolysis method for measuring moisture content. According to different process requirements, the moisture content of compressed air needs to be controlled within a certain range. For example, in some freeze-drying processes that are sensitive to moisture, the dew point requirement for compressed air is extremely strict, and it must be ensured that its dryness meets the process standard.     Oil Content: Lubricating oil may be brought into the compressed air from the compressor. If not controlled, oil droplets may contaminate pharmaceuticals or affect the normal operation of production equipment. By using oil mist detectors and other equipment, the oil content in compressed air can be monitored. Pharmaceutical workshops generally require that the oil content in compressed air is extremely low, even reaching an oil-free level standard, to avoid potential hazards to pharmaceuticals and the production process.   Monitoring Frequency and Methods     Monitoring Frequency: For key production areas and high-risk process links, such as the filling area of sterile pharmaceuticals, high-frequency monitoring is usually required, and tests may need to be carried out daily or per shift. For some relatively low-risk areas or auxiliary production links, the monitoring frequency can be appropriately reduced, but it should also be tested at least once a week or once a month to ensure the continuous stability of the compressed air quality.     Monitoring Methods: Online Monitoring: Utilize various sensors installed on the pipelines of the compressed air system, such as particle counters, dew point meters, and oil mist detectors, to monitor the quality parameters of the compressed air in real-time and transmit the data to the control system for recording and analysis. This method can promptly detect abnormal fluctuations in air quality and facilitate quick measures for adjustment and correction. Offline Detection: Regularly collect compressed air samples and send them to the laboratory for more comprehensive and accurate analysis and testing, including microbial culturing and chemical analysis. Offline detection can serve as a supplement to online monitoring, conduct a more in-depth assessment and verification of the compressed air quality, and also help calibrate and maintain online monitoring equipment. Standards and Regulatory Requirements to Comply With   The pharmaceutical industry is strictly regulated by laws and regulations, and the quality of clean compressed air must comply with relevant international, national, and industry standards. For example, the ISO 8573 international standard provides detailed classifications and regulations on the contents of impurities such as particles, moisture, and oil in compressed air. The "Good Manufacturing Practice for Pharmaceutical Products (GMP)" in China also clearly defines the quality requirements for compressed air in pharmaceutical clean rooms. Each pharmaceutical enterprise must establish a complete compressed air quality management system based on these standards and regulations to ensure that the compressed air used in its production process continuously meets the specified quality standards, safeguarding the quality and safety of pharmaceuticals from the source.   In conclusion, the daily monitoring and standards of clean compressed air in pharmaceutical clean rooms are an indispensable part of the pharmaceutical production process.

In the field of purification, the air treatment methods in air conditioning systems are of vital importance. They are directly related to the air quality and environmental stability of workshops, laboratories and other places, and further affect the production processes and product quality. Today, as a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd., will introduce several common air treatment methods in purification air conditioning systems in detail for you. I. Mixed Air Treatment   Mixed air treatment is a relatively basic and commonly used method. It mixes outdoor fresh air and indoor return air in a certain proportion and then conducts unified treatment. This method makes full use of the cooling and heating capacities of the return air and reduces the energy consumption of the system. For example, in some places where the requirements for temperature and humidity are not particularly strict but there are certain requirements for air cleanliness, such as general electronic assembly workshops, by reasonably adjusting the proportion of fresh air and return air, both air quality can be ensured and energy cost can be saved. The fresh air brings in fresh oxygen and dilutes indoor pollutants, while the return air recovers part of the energy. After mixing, the air undergoes treatment steps such as filtration, heating or cooling to reach a suitable state before being sent into the room. II. All-Air Constant Air Volume Air Treatment   In an all-air constant air volume system, the air handling unit continuously delivers the treated air to the room at a fixed air volume. Its advantage lies in its ability to provide a stable air distribution and temperature and humidity environment. It is suitable for places with high requirements for environmental control and large spaces, such as the clean production areas of pharmaceutical factories. The air handling unit will conduct strict filtration on the air to remove impurities such as dust and microorganisms, and then accurately adjust the temperature and humidity to ensure that the air quality in the entire area is uniform and meets high standards. However, this method is relatively energy-consuming, and it is necessary to reasonably select models and conduct operation management according to actual needs to achieve a balance between energy conservation and environmental control. III. All-Air Variable Air Volume Air Treatment   Different from the constant air volume system, the all-air variable air volume air treatment can dynamically adjust the supply air volume according to the actual load requirements in the room. When there are fewer people moving around or the heat generation of equipment changes, the supply air volume can be reduced, thus reducing energy consumption. For example, in the purification areas of modern office buildings, the number of people and the usage of equipment vary in different time periods, and the variable air volume system can adapt well to such changes. Through sensors installed indoors to sense parameters such as temperature, humidity and carbon dioxide concentration, feedback is given to the control system, which then adjusts the rotation speed and air volume of the fan while ensuring the air purification effect, achieving significant energy-saving effects while meeting environmental requirements. IV. Air-Water System Air Treatment   The air-water system combines the advantages of air treatment and water systems. It usually uses cold water or hot water provided by a chiller to treat the air. Through terminal equipment such as fan coil units, local temperature adjustment of indoor air is carried out, while fresh air is treated by an independent fresh air handling unit and then sent into the room. This method is widely used in some places where there are both comfort requirements and purification needs, such as the surrounding areas of operating rooms in hospitals. The fresh air handling unit ensures air quality, and the fan coil units meet the personalized temperature requirements of local areas. Moreover, the water system has a large heat capacity, which can make temperature adjustment more stable and accurate, and also has certain energy-saving advantages. V. Dedicated Outdoor Air System with Fan Coil Units Air Treatment   In this system, fresh air is treated by a dedicated outdoor air unit and then directly sent into the room, and the fan coil units are responsible for the circulation and temperature adjustment of indoor air. The outdoor air unit undertakes all the tasks of fresh air treatment, including filtration, humidification, dehumidification, heating and cooling, etc., ensuring that the fresh air sent into the room is of high quality. The fan coil units flexibly adjust the indoor temperature according to the needs of indoor personnel. The two cooperate with each other and are suitable for places with high requirements for both indoor air quality and comfort, such as the purified guest rooms of high-end hotels. The advantage of this system is that the temperature of each room can be independently controlled, with high flexibility, and the outdoor air unit ensures the overall air purification effect.   Different air treatment methods have their own characteristics and applicable scenarios. In the actual design and application of purification air conditioning systems, it is necessary to comprehensively consider various factors such as the functional requirements of the place, the size of the area, the density of personnel, the heat generation of equipment and the energy cost, and choose the most suitable air treatment method. Guangzhou Cleanroom Construction Co., Ltd. has rich experience and a professional technical team, and is able to customize the optimal purification air conditioning system solutions according to the specific needs of customers to create a high-quality purification environment for you.   If you are interested in the air treatment methods of purification air conditioning systems or other issues related to purification equipment, please feel free to contact us.
