What is the structure of the doors and windows of the purification room?

Dec 05, 2018

Generally speaking, there are three kinds of structural gaps in most of the purification rooms, doors and windows. One is the combination of diaphragm splicing and installation gap between diaphragm and clean room door; the second is the lap gap between diaphragm and opening fan; the third is the installation gap of glass or other core board. Among the three structural crevices, the first and third belong to fixed crevices and the second belong to active crevices. The proportion of purified doors and windows is different because of their different properties. Therefore, the air-tight measures adopted for the closure of purified doors and windows are not the same.


The number of clean rooms, doors and windows is relatively small nowadays, and the combination of diaphragm and cave entrance is more concealed after decoration, which is a more easily sealed interval gap. The connection between the edge and the periphery of the entrance should be firm. It is not only the requirement of sealing the door and window of the purification room, but also the requirement of the structure of the general purification room door and window. Because of the large and violent force on the door of the clean room, the fixing point around the entrance of the clean room should be paid more attention to whether the course and the fixing point around the entrance of the clean room are firm and stable. But for the closed door and window of the clean room, it is also necessary to emphasize that the gap between the chamber and the entrance of the clean room or the tung tree is filled tightly.


The key point in the design of door and window seal is the treatment of movable gap, which is different from fixed gap in lap, because movable fan needs to be opened. Compared with the window, the opening fan of the purifying door is larger, and the active gap occupies a larger proportion of the total structural gap.www.wxrfcleanroom.com
