The importance of airtightness for air showers
The importance of airtightness for air showersDifferential pressure control is an effective means of maintaining cleanroom air quality and preventing cross-contamination with the external environment. Air shower room as a necessary channel to enter the clean room plays the role of the airlock room, air shower room with two can not be opened at the same time the door, its purpose is to isolate the two differences between the clean environment of the air, to prevent contaminated air into the clean area.But even with the differential pressure control system, a clean room, air shower room can not ensure that in all cases relative to the external environment positive pressure, especially purification equipment air supply system failure or long-time use resistance is too large, positive pressure can not be effectively maintained, this time the air shower room good airtight it is very necessary, can effectively avoid the external contaminated air through the partition wall gap or door, window gap leakage into the clean room. On the other hand, the air shower room work when the wind speed is up to 25m / s, compared to the clean room at 0.45m / s, the wind speed is much larger, and the corresponding pressure is also high, so the air shower room shall be in two doors closed state to blow, when the air shower room blowing, if there is no good airtight, air shower room blowing pollutants will be infiltrated into the clean room with the wind. Clean door using sealing dispensing foam process, CNC dispensing machine AB glue automatic dispensing foam, dispensing seal installed in the door on the inner side, according to the gap size to adjust the amount of dispensing to control the height of the foam and gap a better fit, good airtight; compared to the traditional sealing strips with long service life, has the advantages of anti-bacterial, non-toxic, odorless, no contamination, etc., high resilience, and tensile strength, high endurance, and effectively avoid the traditional sealing strips Easily deformed, easy to fall off, easy to wear and tear, poor elasticity of the inferior qualities. In addition, the air shower room clean door body under the edge of the installation of automatic lifting sweep strip, switching the door automatically pop-up, door body closed pop-up, effectively sealing the gap between the door and the ground. Inside the stainless steel material air shower room using a laser undercutting process, instead of the traditional metal cutting, high precision, speed, smooth and flat cut, the inner wall group joint gap is very small, but also can effectively avoid air leakage and other airtightness problems. |
