Inorganic cloth fire shutter doors, the best suppliers, elected Jinan Xin Tyrone. Inorganic cloth fire shutter doors inorganic cloth fire shutter doors factory fire shutter doors inorganic cloth manufacturers of inorganic cloth fire shutter doors installed fire shutter curtain belong to double-track structure has a certain thickness of the air layer between the two screens side. Each piece of curtain surface consists of three layers of composite material consisting of: by the fire side with the British Terai fireproof refractory cloth, unexposed surface using heat radiation cloth or other refractory cloth, an intermediate insulating layer selection of specially treated aluminum enhanced refractory fiber blanket, curtain side thickness 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. The fire shutter good heat insulation, fully meet the "high regulation" requirement, without the protection of water, is a new super fire shutter. Many places have been widely applied. The fire shutter there is a problem in the course learned: ① selection problem: that is a fire curtain surface material surface, the material should be used in temperature reached 1100 ℃, and now some manufacturers use is to use a temperature lower than 1000 Materials ℃ even without fireproof refractory ceramic fiber cloth surface material by the fire, we can not guarantee the safety of use; b. curtain cloth surface heat radiation, and some manufacturers canceled this layer, and no corresponding increasing the thickness of insulation or air layer, so that the total heat capacity decrease fire shutter; intermediate insulation c curtain surface, and some products are not of sufficient thickness; d curtain surface finishing materials, some using the general retardant cloth, no fire, no fire-resistant, do not wear, short life; sewing e curtain side, some manufacturers use conventional sewing curtains or the sewing plane, but not selected high temperature sewing thread . So that when the fire curtain side effect easily fall apart off-line, can not make full fire curtain surface insulation properties; f curtain plane reinforcing wire rope, it will gradually corroded due to fire shutter life.
