Prefabricated cleanroom engineering involves standardizing and modularizing components according to cleanliness requirements, producing them industrially in factories, and assembling and connecting them on-site to achieve cleanroom standards. Prefabricated cleanroom engineering has become a significant development direction in medical purification engineering in recent years. Its core lies in achieving efficient, high-quality clean environment construction through standardized, modular factory prefabrication and rapid on-site assembly.
Prefabricated cleanroom engineering transforms construction into product manufacturing, characterized by five key features:
The construction process is completed through the assembly of integrated units, employing modular, standardized designs to ensure the safety and quality of clean space construction and usage.
Compared to traditional cleanroom engineering, which relies on on-site installation, prefabricated cleanroom engineering offers:
Cleanroom upgrades are simple and convenient, typically without affecting adjacent units during the process.
Each functional unit ensures that microscopic parameters such as airborne dust particles, bacterial concentration, air pressure, airflow velocity, temperature, humidity, and noise meet the requirements of hygiene and air purification technology, fully satisfying the needs of modern clean spaces.
Prefabricated cleanroom engineering primarily consists of three parts:
Basic facilities for clean operating rooms also include:
Components and facilities for prefabricated cleanroom engineering must not only meet the basic technical requirements of the clean space but also comply with the following:
Frames should be preformed and productized, allowing flexible assembly. Frame deformation must comply with national standards, ensuring sufficient strength and rigidity, with surface treatments meeting relevant requirements.
Enclosure composite panels should meet the requirements of GB/T 29468, "Technical Guide for Application of Sandwich Panels in Cleanrooms and Associated Controlled Environments." Base plates should be metal or resin panels, with substrates made of non-combustible materials rated Class A. When used for exterior walls or ceilings, surfaces should avoid cold bridging and condensation. They should adapt to special requirements such as radiation protection and electromagnetic shielding, with enclosure modules custom-preformed accordingly.
Adapters and connectors for enclosure structures must ensure sufficient reliability and load-bearing capacity. Junctions between walls and ceilings, walls and walls, and ceilings and ceilings should have合理的 structures to ensure sealing and prevent cracking. They should be easy to disassemble and restore for cleaning, inspection, and testing. All detachable connectors should be easily manually connected and fastened after disassembly.
Seams are typically sealed with embedded materials. Sealants should have a smoke toxicity safety rating not lower than ZA2 as specified in GB/T 20285-2006, "Toxicity Classification of Smoke from Materials." They should be self-extinguishing, with self-extinguishing time ≤5 seconds. Gaps between enclosure structures and interfaces for pipelines and wiring penetrating the enclosure should be sealed. Sealing between doors and door frames, cabinets, and control composite panels should comply with GB 50591, "Code for Construction and Acceptance of Cleanrooms." Sealant tolerances should be ±0.3 mm, with shrinkage rate ≤0.5%, and should possess elastic recovery capability.
