Blast doors Profile: Ex door means within a certain period of time to meet the fire resistance stability, integrity and insulation requirements of the door, mainly for the construction of a firewall opening fire district, stairwell entrances and exits, evacuation corridors, wellhead piping, etc., usually used for the movement of persons, in the event of a fire can play to prevent flame spread and prevent combustion flue gas flow, and play a positive role in sealing air system to work. Blast doors first used boating industry in recent years, with the increase in high-rise buildings of its importance in the increasingly prominent buildings, fire safety measures in buildings is one of the most important. Recently, domestic fire-prone, especially in crowded places some fire, precisely because evacuation routes or safety exit door explosion caused by a problem with Qunsiqunshang. 1, in the event of an explosion, according to the explosion incident pressure and the reflected power notice set. Explosion-proof doors can withstand blast pressure range within the species, but to achieve the necessary protection against casualties and property losses. 2, in the case of an explosion, did not meet pre-set explosive, explosion-proof doors can still be used normally. 3, when the explosion occurred, the explosive force reaches the preset can be deformed, but still maintain the use of the components of the door, to avoid personnel are retained, blocking the storm. 4, if necessary, confined isolation, and prevent the direct isolation of space and the outside air convection, was cut off in order to reduce the space protected by external contamination. 5, explosion-proof door is a safe facility, with autistic features and emergency escape capabilities. 6, more suitable for dangerous goods stores, factories, mines, chemical industry and the boiler room of the danger zone.
