Smoke curtain is generally used in shopping malls, factories, and office buildings, etc. It is a device for smoke prevention partitions. The smoke prevention effect is very good, and the appearance is beautiful and practical. It mainly plays a role of preventing smoke and fire prevention. It is generally made of fireproof flexible materials, such as silicone cloth and high silica fabric, and is installed vertically under the building ceiling, ceiling, and beams. If combined with a smoke exhaust system, it can form a certain smoke storage space to make smoke, the air is discharged from the smoke exhaust system, so that the smoke does not spread to other places, thereby gaining valuable and reliable time for the safe estrangement of people.
Silicone coated fabric is a common smoke curtain fireproof material. Gray double sided silicone cloth is often used as a smoke curtain cloth. The thickness is 0.4mm, 0.5mm, 0.65mm, 0.75mm, 0.8mm, 0.9mm, etc. Silicone fabric is made of high-temperature resistant, non-combustible glass fiber cloth as the base cloth, calendered or impregnated with silicone rubber. It is a high-performance, multi-purpose fireproof composite product. Generally speaking, the thicker the thickness of the silicone rubber coating, the better the fire and smoke resistance of the silicone coated fiberglass fabric . Silicone fabric has a variety of excellent characteristics, such as strong sealing, fire retardant, easily for cutting and fabrication and sewn, abrasion resistance, soft and tough, chemical resistance, waterproof, and high strength. The highest temperature resistance of silicone fabric is 550 degrees Celsius, long-term temperature resistance is 250 degrees Celsius, and the high temperature resistance of glass fiber cloth itself is 550 degrees Celsius. Silicone coated fiberglass cloth does not contain asbestos carcinogens, so it can be used with confidence. In addition, the silicone coated cloth reduces the itching sensation of the glass fiber cloth itself to the human body, so that when the human body touches the silicone cloth, it will not cause a significant itch to the human body. The surface of the smoke cloth should be free of cracks, pits, missing corners, holes, obvious bumps, burrs and other defects, and the cloth surface is flat without obvious defects to ensure the smoke-blocking and fire-proof effects. When facing so many manufacturers of silicone coated cloth, how to distinguish the quality of these silicone coated fiberglass fabric? Just grab these few elements:
1. Whether there are obvious defects on the cloth surface;
2. Whether the cloth color is evenly distributed;
3. Whether the fire retardant performance meets the national fire protection standard;
4. Whether the strength of the cloth is qualified;
5. Whether the thickness of the silicone coating meets the requirements;
6. Whether the wear resistance is qualified;
7. Whether the fbrication processability is good;
