Fire shutter door
Inorganic Super Rolling Door
The special fireproof roller shutter is a new type of factory fireproofing. The special inorganic cloth fireproof roller shutter door surface is made of extruded aluminum silicate fiber cloth and coated with an adhesive layer to strengthen the fire resistance as the base material. The transmission structure follows the form of steel fireproof roller shutter. The lightweight design is carried out under the conditions of the opening, and it has the functions and performance of a steel fire shutter, which is suitable for the fire partition of the building.
The special fire shutter door is designed and developed by our company in accordance with the requirements of GB9978-99 "Code for Fire Protection Design of High-Rise Civil Buildings". It does not require water curtain protection. It has manual and electric control, meets obstacles, and automatically lowers functions. Civil building interiors can be used instead of firewalls to complete fire division, and can also be used as general fire shutters.
The special inorganic composite fireproof rolling shutter is divided into type I inorganic fireproof rolling shutter and type II inorganic fireproof rolling shutter. Type Ⅰ fireproof roller shutter surface is 8mm thick and is a single track single curtain surface; type Ⅱ inorganic fireproof roller shutter surface is 20mm thick and is a double track and double curtain surface. Inorganic fireproof rolls have the main properties of steel fireproof roller shutters, long fire resistance, strong heat radiation resistance, can work with their own smoke and temperature detectors, or cooperate with automatic fire alarm systems. Equipped with temperature control fuse device to realize automatic lowering and alarm in the early stage of fire to prevent the fire from spreading. Compared with steel fire shutter, its advantages have the characteristics that the temperature rise of the back surface does not exceed 140C stipulated in GB / TPP78, the installation of spray-free is avoided, the load of the building is reduced, and its safety is more reliable.
Main technical indicators of special grade fire shutter doors:
● The average noise of shutter opening and closing and running should not be greater than 75dB (A)
● Inorganic fiber composite curtain surface thickness and tolerance.
● The inorganic fiber composite curtain surface should be provided with metal plywood plywood along the cloth warp direction
The width is 40mm, the molding thickness is not less than 4mm, and the length is equal to the width of the curtain.
Caused, the error should be no more than ± 20mm, and the distance is 300mm-500mm
● Fire resistance limit: ≥3.00h
Special grade inorganic cloth fireproof rolling shutter door features:
● Inorganic cloth fireproof rolling shutter door runs safely and smoothly with low noise.
● Inorganic cloth fireproof rolling shutter door has beautiful appearance and easy to use.
Steel fire shutter door
The steel fire shutter door is novel in appearance, beautiful in appearance, compact in structure, windproof, fireproof, smoke-proof, and flexible in opening and closing. The smoke and temperature detectors are linked with the fire alarm system, which can realize automatic control in case of fire. It is suitable for fire protection zoning of forging industry and civil buildings. In case of fire, it can block and prevent the spread of flame, reduce losses, and fight for fire rescue time.
● Fire-resistant 3mm thick aluminum silicate fiber cloth is used as the curtain surface, and the steel belt is strengthened in the middle to make it a soft and light roller curtain with the same fire resistance requirements as steel fire-resistant roller shutters
● Light curtain surface, stable operation and low noise can meet the fire partition division of large openings;
● Small installation space and light weight, the average weight of curtain surface is ≤2Kg / m2;
● Fire resistance ≥ 4 hours, no fire deformation, maximum single point temperature of the back surface is 63.5 degrees, average temperature of the back surface is 55.6 degrees; resistance to wind pressure meets the requirements of GB14102-93;
● Safe and reliable operation, stable starting operation and low noise;
● Low energy consumption, eliminating water curtain protection, greatly reducing project cost;
● Opening and closing speed: 2m / min ---- 9m / min;
● It can completely replace the steel fire-proof rolling shutter, and is more suitable for large-span door openings, with a span of up to 30 meters
