(1) It is composed of two layers of Fire prevention curtain, and the air layer with a middle interval of about 250mm. It takes advantage of the good heat insulation of air to enhance the Fire prevention heat insulation performance of the rolling curtain, which has the advantages of light weight, good performance and low price.
(2) Material: The curtain surface is made of inorganic fire-resistant cloth, ceramic fiber blanket, anti-radiation cloth and decorative cloth sewn by high-temperature thread. Both sides are made of galvanized steel strips to ensure the wind resistance of the curtain cloth. The bottom box sealing plate is steely galvanized, with a thickness of 0.8mm and no seams.
(3) The fire resistance of the product is 3h, the average speed of electric opening and closing is 2m/min ~ 7.5m/min, with two-step closing performance and temperature control release performance, screen type double guide inorganic flame retardant cloth, Accessories include transmission device, Fire prevention electric door rolling machine, Fire prevention control box, independent temperature detector, etc.
(4) The Fire shutter does not need to be protected by adding water curtain, which greatly reduces the investment of water supply system and saves water. It also has good smoke blocking performance; Corrosion resistance, acid and alkali resistance, no aging, light weight, low price; No deformation in case of fire; Simple structure, easy to install and use.
(5) When there is no fire alarm, the curtain has the basic functions of manual and electric, such as up, stop, and down, and the upper and lower limits are accurate and reliable
(6) Auxiliary functions: power indicator function, phase out, phase out protection function, overload and overheating protection function
Applicable to the Fire shutter with Fire prevention function in industrial and civil buildings with the temperature rise of the back fire surface of the shutter as the judging condition (average temperature rise ≤140℃, maximum temperature rise ≤180℃) and fire resistance limit ≥3.0h. Especially suitable for Fire prevention partition in places that are not suitable and do not have automatic sprinkler system.
The basic structure and material selection of the curtain should be strictly controlled. The air insulation distance between the two curtains must be guaranteed during installation, that is, controlled within the range of ≥250mm.
