Airflow → Effective air treatment → Air conditioning → Medium effect air treatment → Pressurized air supply of fans → Purified air supply ducts → Efficient air outlets → Clean room → Take away dust (bacteria) .
Repeat the above process to achieve the purpose of purification.
Ventilation times: 100,000 times 10-15 times / hour;
10,000 class 15-25 times / hour;
Thousands class 50-52 times / hour;
The wind speed at the section of the hundred-level operation platform is 0.25-0.35m / s;
Differential pressure: ≥5Pa from the main workshop to the adjacent clean room; ≥10Pa from the clean room to the non-clean area;
Temperature: winter> 16 ℃ ± 2 ℃; summer <26 ℃ ± 2 ℃;
Relative humidity: 45-65% (RH);
Noise ≤65dB (A);
Fresh air replenishment: 20% -30% of the total supply air;
1. The clean room walls and ceiling materials are generally made of 50mm thick sandwich color steel plates and alumina profiles for purification. The door adopts a purifying closed door, and the window adopts an aluminum alloy glass fixed window.
2. The floor is cleaned by epoxy self-leveling or high-grade wear-resistant plastic.
3. Purification and ventilation ducts are made of galvanized sheet steel, and "PEF" flame-retardant insulation boards are used for insulation.
