Folding fire shutter, Anhui folding fire shutter doors plant

Advantages: 1, excellent fire resistance inorganic super fire shutter when according to GB / T7633 (resistance test methods "door and shutter the fire resistance test conducted, in use when the fire back surface temperature for the fire resistance of determination conditions, fire resistance of usual not less than three hours. This performance inorganic super fire shutter is steel fire shutter can not be compared, ordinary, the composite steel fire shutter may fire resistance of more than three hours, but it's the determination conditions measuring the thermal radiation intensity, the shutter to fire back surface temperature is determined to make conditions generally fail to meet requirements. to measure fire back surface temperature is determined as the rolling fire performance conditions are more stringent than done to measure the heat radiation intensity determination conditions Therefore, the refractory inorganic super fire shutter performance is superior to other types of fire shutter 2, reducing the overall project cost "fire protection design of tall buildings" (GB50045-952001 version) Article 544 provides that:. "In setting up a firewall it is really difficult place, it can be used as a fire district fire shutter separated when including the use of fire back surface temperature determine the conditions for the fire resistance of fire shutter, fire resistance of not less than three hours; when using does not include back-fire surface temperature conditions do determine the fire resistance of fire shutter, its volume should be located on both sides of the curtain closed independent automatic sprinkler system protection, system spray duration of not less than 3zbN ";." ordinary fire shutter used in When here, it should be located in a separate closed on both sides of the automatic sprinkler system protection, spray nozzle strength of not less than 0.51 / s.m, nozzle spacing is 2-2.5m, nozzle from shutter the distance is preferably 0.5m, the design of the tank's capacity increased a lot, and inorganic super fire shutter setting up a firewall in place is really difficult to do separate fire district, its volume may not be provided on both sides of the curtain closed independent automatic sprinkler system protection and reduce the overall project cost 3, inorganic cloth fire shutter curtain belong to double-track structure has a certain thickness of the air layer between two layers of each piece of curtain side curtain surface consists of three layers of composite material components..: British Terai by the fire fire fire-resistant surface with a cloth, unexposed surface using heat radiation cloth or other refractory cloth, intermediate insulating layer chosen specially treated enhanced aluminosilicate refractory fiber blanket, face thickness of 10 ~ 20mm. curtain surface transversely through a long thin strip @ 300 ~ 600mm; curtain side longitudinal set of stainless steel wire rope 2mm order @ 1500mm; anti-negative pressure in the rail is provided at both ends of curtain-reinforced steel, increase gap "T "-type structure, negative pressure generated when the surface to prevent fires caused by falling from the curtain rail phenomenon. 4, inorganic cloth fire shutter good heat insulation, fully meet the" high regulation "requirement, without the protection of water, is a new The super fire shutter.
