FAQ What Is The Standard Of 100000 Level Purification Workshop? 2
In terms of air changes:
100000 (100000), 18-25 air changes per hour, and the purification time shall not exceed 40 minutes.
Class 10000 (10000), 25-30 air changes per hour, and the purification time shall not exceed 30 minutes.
1000 (1000), 40-60 air changes per hour, and the purification time shall not exceed 20 minutes.
The cleanliness standards of purification workshops of various grades including 100000 are as follows:
The air cleanliness is classified according to the concentration index of suspended particles, and the particle size limit (lower limit) is within the range of 0.1um~5.0um. According to the particle size, it can be divided into conventional particles (0.1um~5.0um), ultrafine particles (<0.1um) and macro particles (>5.0um).
Structural materials of purification workshop
1）. Generally, the wall and top plate of the plant in the structural part are made of 50mm thick sandwich color steel plate, which is characterized by beautiful appearance, strong rigidity, good thermal insulation performance and easy construction. Arc wall corners, doors, window frames, etc. are generally made of special purification profiles.
2) The ground adopts epoxy self leveling floor or advanced wear-resistant plastic floor, with anti-static requirements.
3) The air supply and return duct is made of hot zinc plating plate, pasted with flame retardant PF foam plastic plate with good purification and insulation effect.
4）. The air supply outlet is sheared and welded into a static pressure box with cold rolled plates, and then sprayed with plastic. The high-efficiency filter is inlaid and fixed, which is beautiful and clean. The perforated mesh plate is made of baking varnish aluminum plate, which is rust free and dust free, and should be cleaned.
Principle of purification workshop
Generally, it goes through three filtering sections: primary filtration, medium efficiency filtration and high efficiency filtration. Air flow → primary purification → humidification section → heating section → surface cooling section → medium efficiency purification → fan air supply → pipeline → high efficiency purification air outlet → blowing into the room → taking away dust, bacteria and other particles → return air shutter → primary purification Repeat the above process to achieve the purification purpose.
100000 level purification workshop standard
1. Maximum allowable number of dust particles (per cubic meter); The number of particles larger than or equal to 0.5 μ m shall not exceed 3500000, and the number of particles larger than or equal to 5 μ m shall not exceed 20000;
2. Maximum allowable number of microorganisms; The number of floating bacteria shall not exceed 500 per cubic meter, and the number of sinking bacteria shall not exceed 10 per petri dish.
3. Pressure difference: the pressure difference between purification workshops with the same cleanliness level shall be consistent, the pressure difference between adjacent purification workshops with different cleanliness levels shall be ≥ 5Pa, and the pressure difference between purification workshops and non purification workshops shall be ≥ 10Pa.
