Purification technical parameters of 100,000-level dust-free workshop


Technical parameters of 100,000-level dust-free workshop 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);
100,000 Class Cleanroom Clothing Attention
1 The staff entering the clean room must wear appropriate clean clothes and shoes, and must not wear oversized or small clean clothes and shoes. Do not wear other people's clothes and shoes.

Safe evacuation in dust-free workshops
There is also an important problem in the layout. Although it is not specifically pointed out in the GMP, as a clean plant with a complex plane, it must be paid attention to. Ease is safe evacuation.
Features of the 100,000-level dust-free workshop:
1. The space is closed. If a fire occurs, it is extremely unfavorable for evacuation and fire fighting. At the same time, because the heat leaks nowhere, the heat radiation of the fire source is reflected by the four walls to make the room heat up rapidly, which greatly shortens the time for the materials in all parts of the room to reach the ignition point. When there are no windows on the exterior wall of the factory building, fires that occur indoors are often not easy to be discovered by the outside world, and it is not easy to select a fire escape breakthrough after discovery.
2. Several clean rooms are colluded with each other through air ducts. When a fire occurs, especially when the fire is not detected at the beginning and continues to be ventilated, the air ducts become an important channel for smoke and fire to quickly escape, simmer and other rooms .
