A production manager at a large pharmaceutical company noted that ordinary color-coated steel panel walls in their workshop suffered extensive coating peeling and severe metal substrate corrosion after just one year in a strong acid-alkali environment. This not only incurred high replacement costs but also disrupted production due to frequent repairs.   In fire protection, while some enterprises used rock wool sandwich panels, non-compliant material density and poor installation practices often led to failed fire safety inspections. A safety supervisor recalled a fire test where flames emerged from rock wool panel joints, exposing critical flaws in traditional fire protection node treatments.   Cleanliness assurance also proved problematic with traditional solutions. Joints in conventional panels were difficult to clean thoroughly, creating ideal breeding grounds for microorganisms. Despite substantial investments in cleaning, enterprises could not fundamentally eliminate contamination risks, posing persistent threats to drug production safety. II. Innovative Solutions from Guangzhou Cleanroom Construction Co., Ltd. (1) Material Innovation: Customized High-Performance Material Systems Guangzhou Cleanroom Construction has collaborated with research institutions to develop specialized high-performance materials for biopharmaceutical workshop conditions:   "Armor Series" 316L Stainless Steel Panels: Used in highly corrosive areas (e.g., chemical synthesis workshops), these panels feature a 2B surface treatment and ≥1.5mm wall thickness, offering 3x higher chloride ion corrosion resistance than ordinary 304 stainless steel. After three years in a high-concentration hydrochloric acid environment, panels in one chemical synthesis workshop showed no visible corrosion. High-Density Hydrophobic Rock Wool Sandwich Panels: With a 120kg/m³ bulk density and 1.2mm galvanized steel keels, these panels achieve a 1.5-hour fire resistance rating. Their fire-resistant sealant expands to block gaps during high-temperature tests, effectively preventing flame spread. Mirror Electrolytic Steel Panels: Featuring a Ra≤0.4μm surface roughness and nano self-cleaning coating, these panels reduce dust and microbial adhesion. In aseptic filling areas, cleaning efficiency improved significantly, requiring only simple rinsing. (2) Process Upgrades: Modular Construction and Precision Detailing The proprietary Honeycomb Modular Construction Process disassembles enclosure structures into standardized 600mm×1200mm modules pre-fabricated in factories, ensuring ≤0.5mm on-site installation accuracy and a 30% shorter construction timeline compared to traditional methods. A 28-day completion of a 2000㎡ antibody workshop project demonstrated reduced environmental impact and accelerated delivery.   For joint treatments, the Interlocking Sealing Technology uses tongue-and-groove + male-female tenon designs with two-component silicone sealant, achieving a leakage rate ≤0.01m³/(㎡·h) in airtightness tests. At wall-penetrating pipe nodes, a "casing protection system" with stainless steel sleeves and elastic fireproof seals prevents contamination penetration, verified by smoke leakage tests. (3) Intelligent Monitoring: Full-Lifecycle Quality Control The "Smart Guardian" monitoring system employs 3D laser scanning during construction to ensure wall verticality (error ≤2mm/m) and flatness (error ≤3mm/3m), with real-time data uploaded to BIM platforms for zero-defect delivery.   During operations, embedded sensors monitor temperature, humidity, and strain 24/7. The system triggers alarms within 10 seconds for issues like corrosion or sealant aging, generating maintenance plans to enable proactive risk management. As one vaccine plant engineer noted, "This system identifies potential issues early, cutting O&M costs and production risks." III. Case Study: Successful Implementation at an mRNA Vaccine Workshop An East China mRNA vaccine enterprise faced dual challenges of strict international compliance and rapid deployment for its new facility. Guangzhou Cleanroom Construction delivered a tailored solution:   Virus Culture Area: 316L stainless steel sandwich panels with DN50 quick-cleaning ports Purification Workshop: 130℃-resistant polyurethane rock wool panels supporting ≥50kg/㎡ ceiling loads Logistics Corridors: 1.2m-high stainless steel crash guards and R≥100mm corner protectors   Post-delivery testing by China Academy of Building Research confirmed:   Cleanroom particle counts (≥0.5μm) ≤3520/m³ (static Class B standard) Air tightness ≤0.5 air changes/hour (top pharmaceutical industry rating) No corrosion or sealant degradation after 1 year of formaldehyde fumigation and heavy equipment use   "Their solution turned our workshop into an industry benchmark," said the client. "It ensures both product quality and production efficiency." IV. Future Outlook: Leading Through Continuous Innovation Guangzhou Cleanroom Construction remains committed to R&D, exploring next-gen materials like self-repairing smart coatings and adjustable composite materials.

The stringent GMP standards impose extremely high requirements on the cleanliness, corrosion resistance, impact resistance, and ease of cleaning of flooring. Additionally, operational conditions such as humid environments, chemical reagent erosion, frequent sterilization, and heavy equipment traffic make flooring engineering a major challenge restricting long-term stable workshop operations. As a professional service provider with years of expertise in the purification field, Guangzhou Cleanroom Construction Co., Ltd. has developed a full-chain solution integrating material selection, process design, and construction management to help biopharmaceutical enterprises overcome flooring engineering challenges. I. Analysis of Core Challenges in Biopharmaceutical Workshop Flooring Engineering (1) Durability Challenges: Performance Tests Under Multiple Operational Conditions Risk of Chemical Corrosion: Frequent contact with strong acids (e.g., hydrochloric acid, phosphoric acid), strong alkalis (e.g., sodium hydroxide), and organic solvents (e.g., ethanol, acetone) during production can easily cause surface peeling, discoloration, and cracking in ordinary flooring materials. Increased Mechanical Wear: High-frequency operation of forklifts and handling equipment, combined with vibration from equipment foundations, can lead to surface wear, sanding, and even structural cracking of the flooring. Impact of Temperature Fluctuations: Temperature variations between high-temperature steam (above 121°C) in sterilization processes and low-temperature storage areas (e.g., cold chain workshops) can cause thermal expansion and contraction in flooring materials, leading to joint delamination. (2) Cleanliness Pain Points: Hidden Threats to Aseptic Environments Crevice Contamination Risks: Joints and expansion gaps in traditional flooring are prone to dust and debris accumulation, creating breeding grounds for microorganisms that are difficult to eliminate through daily cleaning. Surface Adsorption Issues: Non-dense material surfaces easily adsorb pharmaceutical liquids and dust, not only affecting cleanliness but also risking cross-contamination. Inadequate Sterilization Tolerance: Long-term use of ultraviolet sterilization, ozone disinfection, and chemical disinfectants (e.g., peracetic acid) can accelerate aging of ordinary flooring materials and release harmful substances. II. Guangzhou Cleanroom Construction’s Full-Process Solutions: Systematic Breakthroughs from Materials to Processes (1) Precise Material Selection: High-Performance Materials for Stringent Conditions In response to the unique demands of biopharmaceutical workshops, Guangzhou Cleanroom Construction has curated three core material systems:   Epoxy Resin Mortar Flooring: Suitable for general production areas (e.g., batching rooms, packaging areas), this system uses high-solid epoxy resin as the base with quartz sand aggregate for enhanced wear resistance. It offers excellent chemical corrosion resistance (withstands pH 2–12 environments) and a seamless surface, supporting static loads of 20–30 tons. Example: An antibody drug production workshop using this material showed no visible wear after 3 years of frequent ethanol disinfection and equipment handling. Polyurethane Mortar Flooring: Designed for high-demand areas (e.g., aseptic filling rooms, culture medium preparation areas), this system uses imported polyurethane resin and graded sand. It resists extreme temperatures (-40°C to 130°C), impacts (withstands a 10kg ball drop from 1m), and microbial penetration. Its hydrophobic surface repels liquid penetration and is FDA-certified for pharmaceutical contact safety. Vinyl Ester Heavy-Duty Anti-Corrosion Flooring: For highly corrosive environments (e.g., wastewater treatment areas, hazardous waste storage), this system uses vinyl ester resin with glass flake reinforcement, resisting long-term immersion in 98% sulfuric acid and 30% sodium hydroxide, with a service life three times that of ordinary materials. (2) Process Innovation: Creating "Seamless + Functional" Clean Spaces Comprehensive Subfloor Pretreatment: Pre-construction involves shot blasting and grinding to ensure subfloor flatness (≤3mm/3m error) and enhance adhesion via penetrating interface agents, eliminating 空鼓 (hollowing) risks. For retrofits, a unique "crack grouting + carbon fiber reinforcement" process addresses structural defects. Gradient Construction Layers: Primer: Penetrating epoxy sealant blocks moisture and contaminants from the subfloor. Mortar Base Coat: 3–5mm quartz sand mortar layer enhances compressive and impact resistance. Top Coat: Customized finishes (matte anti-slip for walkways, mirror-smooth for cleanrooms, or conductive for precision areas) meet functional needs. Seamless Design Technology: Continuous troweling eliminates joints, while rounded corners (R≥50mm) and custom waterproof weirs around drains/equipment bases create "zero 死角" (zero dead-angle) clean spaces. A vaccine workshop using this process achieved cleanliness metrics 20% better than GMP standards. (3) Intelligent Quality Control: Digital Construction for Assurance BIM modeling pre-plans flooring layouts to simulate equipment loads, drainage slopes, and expansion joint placement. Real-time humidity/temperature sensors (optimal: ≤75% RH, 10–30°C) monitor curing conditions during construction. Post-completion 3D laser scanning verifies flatness and thickness, with data uploaded to a traceable quality management system. III. Case Study: Flooring Engineering at a Biopharmaceutical Production Base Project Background A South China recombinant protein drug production base (including bulk drug, formulation, and logistics areas) required EU GMP and China NMPA compliance. Original flooring failed after 1 year due to bubbling, corrosion, and damage, disrupting production.
