Clean room decoration requires strict adherence to construction and material standards to ensure a sterile, dust-free, and safe environment. The selection and application of materials must meet specific criteria to maintain the integrity and performance of the cleanroom.
1. Elastomeric sealing materials and dust-proof coatings used in cleanroom caulking must be fully labeled with ingredients, product type, manufacturing date, storage instructions, expiration date, and construction methods. A valid certificate of conformity must also be provided. It is crucial to avoid using expired or unapproved products.
2. The cement used for the mortar foundation in cleanroom flooring should not be lower than grade 425. For terrazzo flooring, pebbles of 6–15 mm diameter are recommended. After fine grinding, the surface should be coated with a non-volatile protective layer to prevent contamination.
3. Walls and ceilings in the cleanroom should be finished with high-grade plastering, ensuring adequate curing time. Materials that may cause deformation, mildew, or chalking due to heat or moisture should not be used.
4. Wood used in the cleanroom must have a moisture content of no more than 16%. It should not be exposed directly, and materials like gypsum board or wooden keels should be treated with moisture or waterproof protection. In bio-cleanrooms, wood and traditional plasterboard should not be used as surface finishes.
5. Embedded iron parts, wooden frames, and other components within concrete structures or walls must be securely fastened. Any exposed metal parts should be treated for rust or corrosion resistance.
6. When sealing joints between different materials with elastic sealants, appropriate gaps or slots should be left to allow for proper expansion and contraction.
7. All building components, partitions, ceilings, and suspended elements must be firmly connected to the main structure. No additional brackets (such as conveyor booms, duct hangers, or vibrating equipment) should be attached to pipeline supports.
8. Gaps around doors and windows should be sealed on the positive pressure side to prevent contamination from outside air.
9. During renovation projects, any holes drilled, pipes installed through walls or floors, or partitions removed must be properly repaired and decorated to prevent dust accumulation.
10. Pipeline concealment work should only begin after all pipeline installation and pressure testing are complete. Holes around pipes passing through walls or ceilings should be sealed tightly and cleaned, using appropriate sealing materials. A gas-tight gasket should be placed around inspection ports.
11. A 0.4–0.6 mm thick waterproof film should be laid beneath the cleanroom floor as a moisture barrier. It should be secured with tape, and care should be taken to avoid running electrical lines through the cleanroom area. The moisture content of the base should not exceed 6–8%.
12. Skirting boards should be flush with the wall or slightly recessed by 2–3 mm. If made of the same material as the floor, they can be rounded with an R-radius of at least 50 mm. If different from the floor, elastic material should be used to fill the gap.
The BHC-1300IIA/B3 biological clean safety cabinet is a critical piece of equipment in modern microbiology laboratories, especially those requiring operator protection. It is widely used in medical, pharmaceutical, and research settings to provide a sterile, dust-free, and secure working environment for bacterial cultures.
