Significance of airtight structure in Dongguan clean room
There are many structural gaps in the protective structure of the clean room, such as the panel or seam installation joints of the wall or ceiling, the air inlets of high-efficiency filters, the installation joints of lamps, the installation joints of doors, windows, return air ducts, and perforations of pipelines, etc. The location of the gap is different. For example, the wall is divided into internal and external walls, and there is a technical mezzanine above the ceiling or a general room. Therefore, the loss of air volume caused by leakage or the pollution impact will follow. With the change of the air pressure on both sides of the gap, either the external pollution of the room or the leakage of clean air to the outside, or the alternate between the two at different times, is not comprehensive. , Because the dust-free workshop for the production of some products also requires maintaining a negative pressure with the adjacent room, and not only to take positive pressure measures to prevent pollution or cross-contamination, it is better to take positive measures first to reduce the structural gap and strengthen the gas structure of the gap. Starting from tightness, to minimize air leakage or pollution, in this sense, Tightness is a necessary condition for the design and construction of dust-free workshops. Without such conditions, if you want to maintain a clean operating environment, not only will it increase operating costs in some cases, sometimes it may not even be achieved. It also prominently reflects dust-free The organic connection between airtightness and air purification in the workshop.
