What are the differences between fire shutter and smoke curtain?
The inorganic fireproof roller shutter fabric is made of non-metallic materials after special treatment. Good fire protection. Because the curtain surface is made of non-metallic materials, the thickness of the curtain surface is small and the space is small. The weight of the curtain surface per square meter is not more than 5kg, as long as it is one-fifth of the steel fire shutter, and there is no need for water curtain maintenance, which also reduces the water consumption for fire fighting, and the fire area can be closed in case of fire.
The function of the smoke blocking wall is to hinder the continuous diffusion of smoke. The non-combustible material selected during production is a fixed or movable smoke-blocking facility with a sag of not less than 500mm from the ceiling. The movable smoke blocking wall refers to the smoke blocking wall that automatically sags due to the action of temperature sensing, smoke sensing, or other control equipment during a fire. The smoke blocking wall is a device that separates the smoke area in the large space smoke exhaust system. When the fire control center sends out a fire alarm signal or directly accepts the "smoke sense" signal, the soft smoke blocking wall placed above the ceiling quickly drops to the set height to form a smoke area separation. The high-temperature flue gas is discharged outdoors by the exhaust fan, which creates an environment and buys time for the life-saving and evacuation of people in the fire area.
Cann the fire shutter be used as a smoke curtain? Of course not, the inorganic fire shutter is set when dividing the fire zone, and it closes the area in the event of a fire; the function of the smoke blocking wall is mainly to block the smoke, and the height of the smoke blocking wall from the indoor floor should not be less than 2.0 m. So the two cannot be used indiscriminately.
