What are high temperature aramid fabric insulation materials
Author:
High temperature aramid fabric insulation materials are intrinsically flame retardant fibers, and the processed fabrics do not need to be treated, that is, they have the flame retardant function of colleges and universities. The emergence of aramid fiber has brought revolutionary changes to firefighting clothing. Fire suits are mainly worn by firefighters to put out fires and save lives. In a severe heat environment, it must be able to provide 30~120S time to ensure that the firefighters can leave safely after emergency rescue. Therefore, the outer layer of the fire suit must have sufficient thermal stability and thermomechanical strength to avoid melting or rupture. It is required to have a higher aramid content, generally the content of para-aramid is more than 25%. high temperature aramid fabric insulation materials have excellent heat resistance and good dimensional stability at high temperatures, which are very important for protective clothing, because general textile fibers, especially synthetic fibers, will appear to a greater extent at high temperatures. Shrinkage and melt dripping, the protective clothing made of this material has a large dimensional change after preheating, which will seriously affect its protective performance.
The high temperature aramid fabric insulation materials is a new type of high-tech synthetic fiber, with super strength, high modulus, high temperature resistance, acid and alkali resistance, light weight and other excellent properties, its strength is 5 to 6 times that of steel wire, and its modulus is Or 2 to 3 times that of glass fiber, the toughness is 2 times that of steel wire, and the weight is about 1/5 of that of steel wire, and it will not decompose or melt at a temperature of 560 degrees. It has good insulation and anti-aging properties and has a long life cycle.
The discovery of high temperature aramid fabric insulation materials is considered to be a very important historical process in the material industry. The full name of aramid fiber is "poly-p-phenylene terephthalamide", which is Aramidfiber in English. It is a new type of high-tech synthetic fiber with excellent properties such as super strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. , Its strength is 5 to 6 times that of steel wire, its modulus is 2 to 3 times that of steel wire or glass fiber, its toughness is 2 times that of steel wire, and its weight is about 1/5 of that of steel wire. Decomposes, does not melt. It has good insulation and anti-aging properties and has a long life cycle.
