Structural Material
1. For wall and ceiling materials for the building envelope of the clean room, sandwich color plate of 50mm thick shall be adopted usually, with oxidized alumina material specifically used for purification. Door: adopt purification air-tight door; window: adopt fixed window made of aluminum alloy and glass.
2. Ground: adopt solvent-free, epoxy and self-leveling clean floor or top-quality wear-resisting PVC clean floor.
3. Purification air conduit: select galvanized steel sheet and thermal insulation material.
