Since it is known as the purification room, it must be different from the ordinary workshop. And even its doors and windows have special requirements, so as to ensure the cleanliness of the purification room. Here we should pay attention to the crack treatment of the doors and windows in the purification room carefully.
In general, there are three different types of structural cracks of the doors and windows in the purification room. One is the combination of chamber and the installation crack between the chamber and the door opening in the purification room. The other is the lap crack between the chamber and the open fan. Another is the installation crack of glass or other core plates. f there is air leakage in the purification room, it is possible to produce through these three kinds of cracks.
In the three kinds of crack structures between the doors and windows in the purification room, some are fixed cracks and some are unfixed cracks. The different properties make the proportion of the doors and windows in the purification room different. At the same time, it is necessary to take different airtight measures to ensure the tightness.
For the fixed crack between the doors and windows in the purification room, attention should be paid to the firmness and stability of the fixed points around the holes. It also must emphasize that the crack between the chamber and the door opening of the purification room should be tightly filled. Then covering with the wall finish layer can basically guarantee the air tightness of this kind of crack.
The installation cracks of the glass or other core plates of the doors and windows in the purification room expose to the air, so they are influenced more by the external climate. Therefore, they must be handle with great care when doing the sealing treatment. On the one hand, we should minimize the installation crack of the core glass and on the another hand we should choose the fortification structure carefully..
The lap crack between the door and window is different from the fixed crack. Because it needs to be opened frequently, so the sealing measures are not applicable. Take the single-leaf swing door in the purification room as an example, both sides along the vertical edge are small. The side where installs the handle is often rubbed or impact. The side where installs the hinge is different from the other three sides due to the rotation of the fan. So, we should pay attention to the sealing pertinently.
