hang wallL As one of the reference of fire acceptance in the implementation scope of public buildings, its existence is very important to protect the masses in case of sudden fire. According to the rising principle of smoke, the smoke curtain wall installed in the building ceiling can do a good job in smoke diversion, isolation and storage. So, as such an important security facilities, what aspects should we know about the smoke curtain wall?

 Classification of smoke curtain wall and performance requirements of related products

First of all, to understand the relevant classification of smoke curtain wall. According to the current installation methods of smoke screen wall, there are two types: fixed type and automatic type. The raw materials for manufacturing smoke screen wall are mostly fireproof glass and fireproof silica gel cloth. The existing smoke curtain wall can be divided into three modes: fixed rigid curtain wall, fixed flexible curtain wall and automatic curtain wall. Whether it is rigid or flexible, it should be perpendicular to the horizontal line in normal operation, and the distance between the sagging distance and the top should be about 50cm, so as to ensure a large enough smoke holding and diversion environment.

Secondly, for the finished products that have been marked for sale, the labels of corresponding products should be clearly marked, so that users can clearly understand the relevant data of the products. In view of the metal parts in the product, it is necessary to consider whether there are cracks, uneven, edge burr and other issues. Because the smoke curtain wall is not always able to be used in many years, the corresponding anti rust treatment must be provided on the metal parts, so as to avoid the failure to start timely in case of fire due to no maintenance for a long time.

Finally, the material requirements of smoke curtain wall also need to be checked. Because the application in the fire environment, although not necessarily directly contact with the flame, but does not rule out the situation of facing the fire. According to the requirements of the standard, the heat-resistant temperature of the finished product should be about 620 ℃, which can withstand the high temperature of the flame to ensure the normal operation of the equipment.
