Super fire shutter doors are one kind of products. Today we will take a look at the relevant introduction of super fire shutter doors

classification of super grade fireproof roller shutter door

the curtain surfaces of steam mist steel and evaporative steam mist fireproof roller shutter are the same as that of single plate steel fireproof roller shutter. The former adds a thin-walled steel pipe with small holes in the middle of the serial connection of each curtain piece, and sets two soft rubbers at the two ends of the curtain surface to connect with the thin-walled steel pipe. When a fire occurs, the water flows into the steel pipe through the rubber hose and leaks out from the small hole. When it encounters heat, it vaporizes, absorbs and takes away the heat of the curtain to cool it. The latter is to set a steel pipe on the side of the back fire surface of the curtain, and drill holes on the steel pipe closely. When a fire occurs, water is sprayed on the curtain through the holes, and flows downstream, absorbing heat and evaporating, so as to cool the curtain

double track double curtain inorganic composite super grade fireproof roller shutter door: the fireproof roller shutter belongs to double track double curtain structure, and there is a certain thickness of air layer between the two curtain surfaces. Each curtain surface is composed of three layers of composite materials: the fire-resistant surface is made of interlay fire-resistant cloth, the fire-resistant surface is made of heat radiation resistant cloth or other high-temperature resistant cloth, and the middle insulation layer is made of specially treated reinforced aluminum silicate fire-resistant fiber blanket, with a curtain surface thickness of 10 ~ 20mm

full length thin steel strip @300 ~ 600mm is set horizontally on the curtain surface; 2mm stainless steel wire rope @1500mm is set longitudinally on the curtain surface; In order to resist negative pressure, curtain reinforced steel strips are set at both ends of the guide rail, and the gap is increased “ T” Type structure, to prevent the negative pressure caused by fire from causing the curtain surface to slide from the guide rail. The fireproof roller shutter has good heat insulation, fully meets the requirements of the high standard, and does not need water protection. It is a new super grade fireproof roller shutter. At present, it has been popularized and applied in many places

features of super grade fireproof roller shutter door

the curtain surface is made of inorganic fireproof cloth, anti radiation cloth, fireproof cotton and other layers. It has good bending property, high tensile strength, corrosion resistance and moisture resistance, and the surface can be decorated. The weight of the curtain surface is 3.5 kg/m2, which is particularly suitable for large-span fire-proof roller shutters. It has sensitive opening and closing and low noise, and can be opened and closed by itself or controlled and linked by the fire control center

purchase of super grade fireproof roller shutter doors

first, the fireproof roller shutter is tested according to the current national standard gb7633 "fire resistance test method for doors and roller shutters", including the determination of various judgment conditions including the temperature rise of the back fire surface

second, the fire resistance test is also carried out in accordance with gb7633. According to the provisions of the standard on the temperature rise of the back fire surface of iron sheet roller shutter without thermal insulation protective layer and the requirements of the product standard general technical conditions for steel fire resistant roller shutter (gb14102-93), the roller shutter with fire resistance limit is determined only by the radiant heat intensity at a certain distance from the back fire surface and whether the curtain surface is on fire. The fire endurance data obtained from the non insulated fire roller shutter, which does not include the temperature rise of the back fire surface as the determination condition of fire endurance, is much longer than that of the insulated fire roller shutter, which includes the temperature rise of the back fire surface as the determination condition of fire endurance

I'll introduce the super fire shutter door here. I hope it can help you. More decoration information is here. Please look forward to it
