Door and window structure of purification workshop1

Treatment of gaps in doors and windows of purification workshops Generally speaking, most of the doors and windows of clean rooms have three kinds of structural gaps. The first is the combined splicing and installation gap between the door and the clean room door opening; the second is the lap joint gap between the door and the opening fan; the third is the installation gap of glass or other core boards. Generally speaking, the air leakage of the clean room door is nothing more than the above three. Among the three structural gaps, the first and third types belong to fixed gaps, and the second category belongs to movable gaps. Different properties have different proportions in clean room doors and windows. Therefore, the air tightness measures taken by the door and window seals of the clean room are not exactly the same. A. Fixed gap treatment The inspection installation gap is not only a relatively small number of doors and windows in each camphor tree clean room today, but also the combination of doors and windows and openings after decoration is relatively hidden, which is a fixed gap that is easy to seal. The connection between the edges and corners and the surrounding of the opening should be firm, which is not only the door and window of the closed clean room, but also the requirements of the general clean room door space structure. Due to the large and violent stress of the clean room door, when fixing the clean room door, special attention should be paid to whether the path around the orifice and the fixing point are firm and stable. However, for closed clean room doors and windows, it must also be emphasized that the gap between the chamber and the clean room door or eucalyptus is dense, and then covered with indoor and outdoor wall decoration layers*, which can basically ensure the air tightness of such gaps. Orange pharma clean room doors have a relatively small proportion of clearances, but tend to be a major part of the structural clearances of a chamber, especially the outer chamber. They are exposed to the atmosphere, affected by the outdoor climate and must be handled carefully. On the one hand, the installation gap of the core glass should be minimized, and on the other hand, the fortification structure should be carefully selected. Handle active gaps. How to connect the opening fan of the clean room door with the frame material is the key to the sealing design of the clean room door. Unlike fixed gaps, wood can be sealed once and for all because the movable fan needs to be opened. Compared with Zhou, the opening fan of the clean room door is larger, and the active clearance occupies a larger proportion of the total structural clearance of the clean room door. The clean room door is opened more frequently than the universe, and the working conditions of the gap around the clean room door are also more complicated. Taking the single-leaf swing clean room door as an example, it is smaller along the vertical sides. The side of the assembly hand is often subjected to various frictions or collisions when passing through, and the hinge side, due to the rotation of the fan, exerts force on the direction of the chamber. Completely different from the other three sides. Previous: What are the standards for the dust-free purification pharmaceutical cleanroom of masks?
