The shutter door manufacturers fire shutter door concept is novel and simple

Release date:2018-05-31 Author: Click:

The fire surface material of the fire shutter door of the rolling door manufacturer should be selected from materials with a temperature of 1100 ° C. However, some manufacturers now use materials with a temperature lower than 1000 ° C, and even refractory and non-fireproof aluminum silicate fibers. The cloth is made of fire surface material, and the safety of the use cannot be guaranteed; the heat radiation cloth of the curtain surface is removed by some manufacturers, and the thickness of the heat insulation layer or the air layer is not increased correspondingly, so that the total of the fire shutter The heat insulation capacity is reduced; the middle insulation layer of the curtain, some products do not have sufficient thickness; the decorative materials of the curtain surface, some use general flame-retardant cloth, no fire, no fire, no wear, short service life; For the sewing thread of the curtain, some manufacturers use ordinary or medium sewing thread in the sewing curtain, and do not use high temperature resistant sewing thread. When the curtain is in the fire, it is easy to fall off the line, and the curtain can not fully exert the fire and heat insulation performance; the reinforced wire rope in the curtain will affect the service life of the fire shutter due to the gradual corrosion. The total thickness of the fireproof roller blind is about 450mm~500mm. Underneath it, no business showcases and any items are stacked, which occupy the effective use area. The price per unit area of the shopping mall is high, which is unwilling. In some projects, the double curtain double rails are abutted during installation, the air layer between the two curtains is greatly reduced, and the heat insulation capacity of the entire inorganic fireproof roller blind is also significantly reduced, so that the fire separation is hidden. Double-track double-curtain inorganic composite fire shutter, the curtain material should have excellent high temperature resistance and very low thermal conductivity. At present, there are many kinds of products on the market, and the performance prices are different. Special attention should be paid to the selection and selection of suitable inorganic fiber refractory materials in the design and selection of materials to ensure that the performance of the dual-track double-curtain inorganic composite fire shutters is consistent with the qualified product fire resistance test report.
