Clean workshop: fully enclosed clean room, class 100- 300000 purification. The room body is formed by EPS color plate, made by machine and assembled on site, arc treated inner walls, epoxy self-leveling floor, to prevent dust accumulation. Purifying lights are reasonably arranged at the top surface, the wall has a large window, to increase lighting and perspective; the air circulation system formed of air supply and exhaust unit ensures clear and clean of the indoor air.
Clean room structure materials
1.The wall and roof materials usually adopt 50mm sandwich color plate, purification specialized aluminum oxide to produce. The door of clean room uses purification air-tight door, the window uses aluminum alloy glass fixed window.
2.Clean room floor uses epoxy self-leveling floor of advanced abrasion resistance plastic clean floor.
3.Clean room ventilation pipe uses galvanized steel sheet to produce, and uses “PEF”flame-retarding insulation board to keep warm. Cleanliness class of clean room and suspended particles in the air: equal ISO air cleanliness is greater than or equal to the maximum particle concentration limit (P/m - air) cleanliness grade in the watch.
Clean room is also called dust free room. It is the basis to control pollution. Without clean room, contamination sensitive parts are not likely to be produced in batches. In FED-STD-2, clean room is defined as a room for air filter, distribution, optimizing, constructing materials and devices, in which the specific rule of operation procedure to control airborne particle concentration so as to achieve proper level of particle cleanliness.
Clean room is a special designed room to eliminate corpuscle, harmful air, bacteria and other pollutants in the air within a certain area, and to control indoor temperature, cleanliness , indoor pressure, airflow speed, airflow distribution, noise vibration, light, static within a certain requirement scope. That is, no matter how the external air conditions change, the indoor can keep the original set of cleanliness, humiture, pressure and other performances. The main function of clean room is to control cleanliness and humiture of air the product(such as silicon chip) contacted, make the product produced and manufactured in a good environment, such space we called clean room.
Fabricated clean room system mainly consists of air conditioning air supply, return and exhaust system of primary, medium, high efficiency filter; power and lighting system; work environment parameters monitoring alarm, fire and communication system; flow and logistics system; process pipe system; maintenance structure and eletrostatic floor treat and other required implementation content.
1. All the maintenance components of fabricated clean room are processed in the industry according to unified modules and series, suitable for mass production, with stable quality and fast delivery.
2.Flexibility, that is suitable for new plant matching installation, also for purification technology transformation of old plant. The maintenance structure can also be assembled freely according to technique requirements, convenient disassembly.
3.It needs small auxiliary building area and low requirement for soil building decoration.
4.The airflow organization form is flexible and reasonable, which can meet the needs of different working conditions and different cleanliness classes.
