Product characteristics

Super inorganic composite fire shutter face 1.2mm thick, double track, double curtain face. The inorganic fire shutter has the main performance of the steel fire shutter door, the fire resistance time is greater than 3 hours, the heat radiation resistance is strong, and the smoke and temperature detector can work independently or be linked with the automatic fire alarm system. Equipped with temperature control fuse device, to achieve the initial fire automatic descent, alarm, prevent the spread of fire. In addition, compared with the steel fire shutter door, it has the advantage of the temperature rise of the back fire surface does not exceed 140 ° C specified in GB/TPP78, no spray, light rolling shutter weight, reducing the load of the building, and its safety is more reliable.

Construction and use of double track super fire roller curtain

Because the fire-proof base material is inorganic fabric, it has the advantages of light weight and good overall performance, the overall weight of the roller shutter is significantly lower than that of the steel roller shutter, and the installation method is simple and easy to operate, which greatly breaks through the fixed requirements of the traditional steel roller shutter on the size of the hole, saving space for the building and providing great convenience for the reasonable design of the building.

Double-track super fire roller curtain This roller curtain adopts hierarchical transmission mode, with expanded aluminum silicate fiber cloth and silicon ester aluminum fiber felt as heat insulation fire retardant substrate, and with appropriate air insulation layer to strengthen the heat insulation capacity, its chemical part in the original fire roller curtain structure on the basis of major improvements, strengthen the hierarchical roller curtain shaft, compound guide rail and so on. In the four-hour experiment process, the single point temperature of this kind of curtain is up to 103 degrees, and the average is only 84 degrees, which achieves the function of fire and smoke prevention, and can be opened and closed completely and smoothly. The traditional steel fire curtain must be equipped with water curtain protection in order to meet the requirements of replacing the firewall. This double-track super fire curtain can completely replace the firewall to complete the fire partition task, so that the building can cancel the water curtain protection in the case of using this fire curtain, which can save millions of funds for the construction unit.

What steps does it take to go from inorganic to Super?

First of all, let's understand what inorganic fire roller curtain and super fire roller curtain are.

Inorganic fireproof roller curtain is mainly made of inorganic fireproof fiber through special processing, and has the functions of fire prevention, smoke prevention and heat insulation. Super fire roller curtain refers to the roller curtain with steel material or inorganic fiber material as the curtain surface, with steel material as the guide rail, seat plate, plywood, door lintel, box, etc., and equipped with door rolling machine and control box can meet the fire integrity, heat insulation and smoke prevention performance requirements. Inorganic fire roller curtain material is inorganic cloth, in order to achieve the super fire roller curtain must be made of double track double curtain, and steel to achieve the super general to add water spray.

The above is the inorganic fire roller shutter to achieve the requirements of super fire roller shutter.

Fire prevention device Fire and smoke prevention mechanism

Fire shutter and fire smoke shutter are necessary products for fire and smoke prevention in large opening or large area shared space, and can not be replaced by general flat fire doors. Now the size width and height that domestic manufacturers can provide can reach 15m, it can usually be hidden in the ceiling ceiling, matched with the temperature sensor and smoke detector, can reach the smoke signal when the door drops to 1.8 meters from the ground, so that the area forms a smoke blocking trough to prevent the spread of smoke to other zones. When the temperature signal comes, the door body will be lowered to the ground after the disaster is confirmed, the fire source will be cut off, and the sound and light alarm will be issued to guide the rapid evacuation of personnel. If there are still people in the disaster area who are not evacuated in time, the door can still be raised to a height of 1.8 meters from the ground by the buttons on both sides of the door, and the back door will be closed in time to prevent fire smoke from escaping.

In addition, in view of the problem that the rolling shutter door can not play a role in the case of no power supply, the relevant units have developed a "fire-proof rolling shutter door fuse release and place" that opens the deceleration clutch in the case of no power or cut off the power supply, so that the fire-proof rolling shutter door can still play its due role in the case of no power and no one.
