Guangzhou Cleanroom Construction Co., Ltd. company cases

In modern industrial production, the importance of cleanrooms is self-evident. Especially for industries with extremely high environmental requirements, such as semiconductor manufacturing, biomedical research and development and production, and precision optical instrument processing, even tiny particles can have a serious impact on product quality, production efficiency, and the lifespan of equipment. Guangzhou Cleanroom Construction Co., Ltd., as a professional enterprise in purification projects, has been always committed to researching and applying advanced particle control technologies to create high-standard cleanroom environments for numerous industries. 1. Air Filtration System - The Core Defense Line for Purification   The air filtration system is the key to controlling particles in cleanrooms. It mainly consists of primary filters, medium-efficiency filters, and high-efficiency particulate air (HEPA) filters or ultra-low penetration air (ULPA) filters. Primary filters can intercept larger particles in the air, such as dust and hair. Generally, their filtration efficiency for particles with a diameter greater than 5 micrometers can reach more than 80%. Medium-efficiency filters further filter medium-sized particles, and their filtration efficiency for particles with a diameter between 1 and 5 micrometers can reach 70% - 90%. HEPA filters have a filtration efficiency of over 99.97% for particles with a diameter of 0.3 micrometers and above, while ULPA filters can even increase the filtration efficiency for particles with a diameter of 0.12 micrometers and above to over 99.999%. These different levels of filters work together to ensure that the air entering the cleanroom is almost free of particles, providing an extremely pure air environment for the production process. 2. Optimization of Airflow Organization - Precise Guidance of Airflow   Reasonable airflow organization also plays an indispensable role in particle control. By carefully designing the positions, shapes, and air volume of supply air outlets and return air inlets, specific airflow patterns can be formed within the cleanroom. Common airflow organization forms include unidirectional flow (laminar flow) and non-unidirectional flow (turbulent flow). Unidirectional flow moves evenly and stably in parallel streamlines, which can quickly and effectively carry particles out of the clean area. It is suitable for areas with extremely high cleanliness requirements, such as the lithography process workshop in chip manufacturing. Non-unidirectional flow makes use of the clean air sent out from the supply air outlets to fully mix with the air in the workshop and reduces the particle concentration through multiple cycles of dilution. It is widely used in workshops with general cleanliness requirements. In addition, facilities such as air curtains and air showers can be set up to form an "air barrier" at the entrance of the workshop, preventing the intrusion of polluted air and particles from the outside. At the same time, they can also effectively remove the particles carried on the surfaces of personnel and materials when they enter or exit. 3. Electrostatic Adsorption Technology - Efficient Capture of Particles   Electrostatic adsorption technology is an innovative means of particle control. By utilizing the effect of an electrostatic field, particles in the air are charged and then adsorbed by collectors with opposite charges. This technology has a very high capture efficiency for tiny particles, especially sub-micron particles that are difficult to be effectively removed by traditional filtration methods. In some local areas with extremely strict requirements for particles and relatively limited space, such as the sample preparation area of an electron microscope laboratory, electrostatic adsorption devices can be used as auxiliary equipment in combination with traditional air filtration systems to further improve the air purification effect. It not only can remove particles efficiently but also has the advantages of low resistance and low energy consumption, which helps to reduce the operating costs of cleanrooms. 4. Surface Treatment and Cleaning - Reducing Secondary Pollution Sources   If the surfaces of equipment, walls, floors, etc. in the cleanroom are not smooth and clean enough, they are likely to become secondary pollution sources of particles. Therefore, special treatment and regular cleaning of these surfaces are of vital importance. For example, using materials that are smooth, not easy to accumulate dust, and have anti-static properties to decorate the internal surfaces of the workshop can reduce the adhesion of particles. Meanwhile, strict cleaning regulations should be formulated, and professional cleaning tools and cleaning agents should be used to regularly wipe and vacuum the surfaces of the workshop to ensure that the surfaces always maintain a low particle adhesion state. In some areas with extremely high cleanliness requirements, such as aseptic drug filling workshops, even automated cleaning robots will be used to conduct comprehensive and meticulous cleaning of the workshop during production breaks to minimize the risk of surface particle pollution. 5. Personnel and Material Management - Preventing Pollution at the Source   People are one of the biggest pollution sources in cleanrooms. The activities of personnel can generate a large number of particles such as dander, hair, and fibers. Therefore, personnel management is an important part of particle control. Personnel entering the cleanroom must wear clean work clothes, masks, hats, shoe covers, and other protective equipment that meet the requirements. They can only enter after passing through purification facilities such as air showers to remove the particles carried on their surfaces. At the same time, the number of personnel and their activity ranges should be limited to reduce unnecessary movements. Materials are also potential sources of particles. Materials entering the cleanroom must undergo strict cleaning, disinfection, and packaging processes. During transportation and storage, dust-proof and anti-pollution measures should be taken to ensure that no additional particle pollution is introduced when the materials enter the production process.   Particle control technologies in cleanrooms are a comprehensive and systematic project, which requires comprehensive consideration and careful design from multiple aspects such as air filtration, airflow organization, electrostatic adsorption, surface treatment, and personnel and material management. Guangzhou Cleanroom Construction Co., Ltd., relying on its rich experience, advanced technologies, and professional team, can customize the most suitable particle control solutions for customers and create high-quality cleanrooms that meet the needs of different industries, helping enterprises achieve efficient and stable production and operation under strict environmental requirements.  

In the construction of cleanrooms, the ventilation project plays a pivotal role. It is not only related to the maintenance of air quality inside the workshop but also closely associated with the smooth progress of the production process and the health and safety of personnel. Guangzhou Cleanroom Construction Co., Ltd., relying on years of in-depth work in the purification field, has accumulated rich experience in the design and construction of ventilation projects for cleanrooms. The following is a detailed analysis of the key points for you. I. Key Points in Ventilation Project Design (1) Calculation of Ventilation Volume   Accurate calculation of the ventilation volume is the foundation of ventilation project design. It is necessary to comprehensively consider various factors such as the area of the workshop, the height of the space, the number of personnel, the heat generation and dust production of equipment. For example, in a cleanroom with a dense population, it is necessary to ensure that there is a sufficient supply of fresh air per person per hour. Generally, it is calculated according to the standard of [specific value] cubic meters per person per hour. For workshops with a large number of heat-generating equipment, the ventilation volume should be determined based on the heat dissipation of the equipment to effectively discharge heat and maintain the temperature of the workshop within a suitable and stable range. (2) Design of Airflow Organization   A reasonable airflow organization can evenly distribute purified air and effectively remove pollutants. Common airflow organization forms include unidirectional flow (laminar flow) and non-unidirectional flow (turbulent flow). Unidirectional flow is suitable for areas with extremely high cleanliness requirements, such as the core area of a chip manufacturing workshop. Through high-efficiency filters, the air flows evenly and stably in parallel streamlines, which can quickly carry away dust particles. Non-unidirectional flow is more commonly used in workshops with general purification requirements. By rationally arranging the supply air outlets and return air inlets, a mixed air flow is formed in the workshop to achieve the purpose of diluting and removing pollutants. (3) Adaptation to Cleanliness Levels   Different production processes have different cleanliness level requirements for cleanrooms, and the design of the ventilation system must be adapted to them. For example, in a pharmaceutical aseptic production workshop, it may be required to reach a cleanliness level of ISO 5 or even higher. This requires the ventilation system to be equipped with highly efficient air filtration devices. For example, HEPA filters have a filtration efficiency of over 99.97% for particles larger than 0.3 micrometers, and the ratio of supply air to return air and the air velocity must be strictly controlled to prevent the accumulation of dust and microorganisms. (4) Layout of Ventilation Ducts   The layout of ventilation ducts should be simple and smooth, reducing the use of elbows and resistance components. The material of the ducts should be selected according to the environmental characteristics of the workshop. For example, in workshops with the risk of acid and alkali corrosion, corrosion-resistant stainless steel or plastic ducts should be used. In general environments, galvanized steel sheet ducts are more commonly used due to their good strength and economy. Meanwhile, attention should be paid to the sealing of the ducts to prevent air leakage from affecting the ventilation effect. II. Key Points in Ventilation Project Construction (1) Installation of Equipment   The installation of ventilation equipment must be carried out in strict accordance with the specifications. Fans should be installed stably to ensure that there is no abnormal vibration or noise during operation, and vibration reduction measures, such as installing vibration pads or spring vibration dampers, should be taken. The installation of air filters should be tight, and the sealing strips should be intact to prevent unfiltered air from bypassing and entering the workshop. In addition, for large equipment such as air conditioning units, it is necessary to ensure that the internal components are firmly connected and that the refrigeration and heating systems operate normally. (2) Installation of Ducts   During the installation of ducts, it is necessary to ensure that the slope of the ducts meets the design requirements so that condensate water can be discharged smoothly, avoiding water accumulation that may breed bacteria and affect air quality. The connection of ducts should be tight, and welding, flange connection or threaded connection can be adopted, and sealing treatment should be done at the connection points, such as winding sealing tape or applying sealant. When passing through walls or floors, sleeves should be set up, and fireproof, waterproof and sealing materials should be filled between the sleeves and the ducts. (3) Commissioning and Testing   After the completion of the ventilation project construction, commissioning and testing are of crucial importance. First, the air volume and air pressure of the fans should be tested to ensure that they meet the design requirements. Then, the air change rate and air cleanliness of the entire ventilation system should be detected. Professional instruments and equipment such as dust particle counters and airborne microorganism samplers can be used. Based on the test results, necessary adjustments and optimizations should be made, such as adjusting the fan speed and replacing filters, until all the indicators of the system meet the standards and requirements of the cleanroom.   The design and construction of the ventilation project for cleanrooms is a complex and rigorous process that requires professional knowledge and rich experience. Guangzhou Cleanroom Construction Co., Ltd. is always committed to providing customers with high-quality and customized ventilation project solutions. From design to construction, every link is strictly controlled to ensure that cleanrooms can operate efficiently and stably, creating good environmental conditions for the production and development of enterprises.

In the construction of refrigeration and purification workshops, the selection of decoration materials is a crucial link, which is directly related to the functionality, stability and overall quality of the workshops. Guangzhou Cleanroom Construction Co., Ltd. specializes in the purification field and deeply understands the great significance of material selection for refrigeration and purification workshops. Next, we will explore in depth the important factors that need to be considered when choosing decoration materials for refrigeration and purification workshop projects. 1. Temperature and Thermal Insulation Performance   Refrigeration and purification workshops have strict requirements for temperature. Therefore, the selected decoration materials must have excellent thermal insulation performance. For example, high-quality thermal insulation panels can effectively block heat transfer, reduce the load on refrigeration equipment, and thus lower energy consumption. Polyurethane sandwich panels are an ideal choice. They have a high closed-cell rate and a low thermal conductivity, which can maintain the low-temperature environment of the workshop while saving a lot of operating costs for enterprises. 2. Cleanliness and Dustproof Performance   The core of a purification workshop lies in maintaining high cleanliness, which requires the decoration materials to have good dustproof performance. For wall materials, color steel plates can be selected. Their surfaces are smooth and flat, not easy to accumulate dust, and are convenient for cleaning and disinfection. For floor materials, epoxy self-leveling floor coatings are recommended. They are seamless and can effectively prevent dust accumulation, ensuring that the workshop floor remains clean all the time. 3. Corrosion Resistance   In some special refrigeration and purification workshops, such as those in the food processing and chemical industries, there may be contact with corrosive substances like acids and alkalis. At this time, the corrosion resistance of decoration materials becomes particularly important. For example, stainless steel materials have excellent corrosion resistance and are often used to make workbenches, shelves and other facilities in the workshop. For walls and ceilings, corrosion-resistant coating materials can be selected to extend the service life of the decoration materials. 4. Fire Resistance   Safety is an issue that cannot be ignored in any project, and the refrigeration and purification workshop is no exception. The decoration materials should have certain fire resistance performance to reduce the risk in case of a fire. Fireproof boards, fireproof coatings and other materials can improve the fire rating of the workshop to a certain extent, providing safety guarantees for personnel and equipment. 5. Antibacterial Performance   To ensure product quality and personnel health, the decoration materials for refrigeration and purification workshops should also have antibacterial performance. Some new antibacterial materials can inhibit the growth and reproduction of microorganisms such as bacteria and molds, effectively reducing the possibility of cross-contamination. 6. Cost and Cost-effectiveness   When choosing decoration materials, cost is also an important consideration factor. Enterprises need to comprehensively consider factors such as the price of materials, installation costs and service life on the premise of ensuring the quality and performance of materials, and choose decoration materials with high cost-effectiveness. Guangzhou Cleanroom Construction Co., Ltd., relying on its rich experience and professional team, can provide customers with the most optimized material selection schemes to help customers build high-quality refrigeration and purification workshops within the budget.   In conclusion, the selection of decoration materials for refrigeration and purification workshop projects needs to comprehensively consider multiple factors such as temperature, cleanliness, corrosion resistance, fire resistance, antibacterial performance and cost. Only by choosing appropriate decoration materials can the efficient operation of refrigeration and purification workshops be ensured, providing strong support for the production and development of enterprises. Guangzhou Cleanroom Construction Co., Ltd. will, as always, provide professional purification project solutions for customers and help enterprises achieve greater success in the purification field.  

In numerous industries that pursue high - quality air environments, medium - efficiency glass fiber bag filters, with their unique performance and advantages, have become indispensable equipment for ensuring air cleanliness. Guangzhou Cleanroom Construction Co., Ltd., as a professional provider of purification equipment, is here to provide you with an in - depth analysis of medium - efficiency glass fiber bag filters. I. Structure and Principle of Medium - efficiency Glass Fiber Bag Filters   Structural Features Medium - efficiency glass fiber bag filters mainly consist of filter bags made of high - strength glass fiber filter materials. These filter bags usually have a multi - bag structure and are carefully designed and installed within a sturdy metal frame. The shape of the filter bags is mostly long and slender, which can maximize the filtration area and thus improve the filtration efficiency. Moreover, the metal frame ensures the stability of the entire filter during installation and use, enabling it to withstand certain wind pressures without deformation. Filtration Principle Its filtration principle is based on multiple mechanisms such as interception, inertial impaction, and diffusion. When dust - laden air enters the filter, larger particles will be intercepted directly by hitting the glass fiber filter material due to inertial effects; medium - sized particles will be captured when the air flow passes through the filter bags and they constantly change their moving directions in the tortuous channels among the fibers; and even smaller particles will diffuse onto the fiber surfaces through Brownian motion and then be adsorbed. Through these combined effects, contaminants such as dust, pollen, and fibers in the air are effectively filtered out. II. Outstanding Performance Advantages   High Filtration Efficiency Medium - efficiency glass fiber bag filters have excellent filtration effects on particulate matter within the particle size range of 1 - 10 microns. Under the rated air volume, their filtration efficiency can usually reach about 40% - 90%, effectively capturing suspended impurities in the air, ensuring air cleanliness, and meeting the needs of general industrial production and some places with relatively high requirements for air quality. Low Resistance Characteristics While ensuring filtration efficiency, these filters have relatively low air resistance. This benefits from the special structure of the glass fiber filter material and the reasonable bag - shaped design. Lower resistance means that the energy consumption required by power equipment such as fans during operation is lower, which not only saves energy costs but also extends the service life of the fans. High Dust Holding Capacity Thanks to the use of glass fiber materials and the bag - shaped structure, medium - efficiency glass fiber bag filters have a relatively large dust holding capacity. During long - term operation, they can accommodate more dust and impurities, reducing the frequency of frequent filter replacement, lowering maintenance costs and workload, and improving production and operation efficiency. III. Wide Range of Application Scenarios   Commercial Building Sector In large shopping malls, office buildings, hotels and other commercial buildings, medium - efficiency glass fiber bag filters can be installed in the central air - conditioning systems. They can effectively filter pollutants in the air introduced from the outside, such as dust and smoke, providing a fresh and comfortable air environment indoors and improving the comfort and work efficiency of indoor personnel. Industrial Production Sector For some industrial production workshops with certain requirements for air quality, such as electronics factories, pharmaceutical factories, food processing factories, etc., this type of filter can be used as primary or intermediate filtration equipment. It can prevent dust and other pollutants from entering the production area, avoid adverse effects on product quality, and ensure the smooth progress of the production process. Medical and Healthcare Sector In hospitals, nursing homes and other medical and healthcare places, medium - efficiency glass fiber bag filters can be used in ventilation systems.
