Product features
(1) is composed of fire shade on the second floor, the interval of about 250 mm or more air layer, the use of air insulating good stays, strengthen the shutter fire insulation performance, has advantages of light weight, good performance, low price.
Refractory performance for 3 h (2) products, electric opening and closing the average speed of 2 m/min to 7.5 m/min, with two steps closing performance and temperature control release performance of inorganic flame retardant cloth, curtain plate type double guide rail accessories with actuator, electronic fire prevention, fire control box, detached thermal detector, etc.;
(3) the fireproof rolling curtain does not need the water curtain protection, greatly reducing the investment in the water supply system and saving the water supply. It also has good smoke resistance; Anti-rust, acid and alkali resistant, not aging, light weight, low price; The fire does not deform; Simple structure, convenient installation and other advantages.
Using range
Applicable to fire shutter back surface temperature rise as the decision condition (the average temperature of 140 ℃ or less, the highest temperature of 180 ℃ or less), fireproof limit of 3.0 h or industrial and civil architecture, with functions of fire of fire shutter. It is especially suitable for fire partition partition of places where automatic sprinkler system is not suitable.
Type and performance metrics.
The basic structure and selection of the curtain surface shall be strictly controlled. The air insulation distance between the two curtain surfaces must be guaranteed in the installation, that is, the control is within the range of 250mm.
