Purification plant engineering structural materials
a. Purification plant walls and ceiling boards are generally made of 50mm thick sandwich color steel plates, which are characterized by beautiful appearance and strong rigidity. Arc wall corners, doors, window frames, etc. are generally made of special alumina profiles. B. The floor can be epoxy self-leveling floor or high-grade wear-resistant plastic floor.
c. The return air duct is made of hot-dip zinc plate, and it is attached with flame-retardant PF foamed plastic plate with good purification and heat preservation effect.
d. High-efficiency air outlet stainless steel frame, beautiful and clean, perforated screen with painted aluminum plate, no rust and no sticky dust, should be cleaned
Purification plant engineering purification parameters
Ventilation times: 100,000 levels ≥ 15 times; 10,000 levels ≥ 20 times; 1000 ≥ 30 times. Differential pressure: the main workshop to the adjacent room ≥ 5Pa average wind speed: 10, 100 0.3-0.5m / s; temperature winter> 16 ℃; summer <26 ℃; fluctuation ± 2 ℃.
The temperature is 45-65%; the humidity in the GMP powder workshop is about 50%; the humidity in the electronics workshop is slightly higher to avoid static electricity.
Noise ≤65dB (A); fresh air supplement is 10% -30% of total supply air volume; illumination 300LX
