Smoke curtain fabric is generally made of fireproof silicone coated fiberglass fabric or high silica fabric or wire reinforced glass fabric, and the fixed or movable smoke blocking facility with a droop of not less than 500 mm from the ceiling is mainly used for high-rise or super high-rise large shopping malls, office buildings, factories, warehouses and other occasions. When the fire control center sends out a fire alarm signal or a smoke signal, the flexible smoke curtain placed above the suspended ceiling will quickly drop to the set height to form a smoke zone separation, which can effectively block the horizontal flow of smoke under the building ceiling, and then the smoke fan discharges high-temperature smoke outdoors, which can improve the smoke exhaust effect in the smoke-proof zone, create an environment and buy time for life-saving and evacuation in the fire alarm area, and play a certain role in ensuring the safety of people's lives and property.
According to the installation method, the smoke curtain is divided into fixed type and rolling curtain type. The height of the fixed type in china is generally 500mm and 600mm.
