Fire-retardant insulation material mainly used in
firefighter clothing, firefighters deal with death, the spirit of selfless support face of danger stems from respect for life. Fireman equipment requirements are very strict, it is directly related to the personal safety of firefighters. Clothing protective equipment are subjected to high temperatures to avoid firefighters, drugs and other harmful environmental damage overalls, helmets, boots, hats, glasses and so on.
Fire fighting clothing are firefighters put out the fire into the general fire fighting to protect themselves while wearing protective clothing, suitable for the fire "normal" state of use. Fire fighting clothing fabrics commonly used flame retardant textile fabrics. Currently, most foreign countries such as the United States, France, Japan, Britain and other countries are based on the aromatic polyamide fiber fabric, this fabric has good flame retardant properties, high strength, high thermal stability, combustion products low toxicity, and has a certain acid properties; Nomex is DuPont products Nomex fibers have good thermal stability, does not melt at 377 degrees, but will decompose; g secret Seoul is a polyamide imide made, and belong to a family of aromatic polyamide, due Mill grams fiber surface is almost circular cross-section, so the texture is softer than other polyamide fabric, g Mill also to stop the chemicals, wear resistance and strength, thermal conductivity than aramid fibers is half the other fabrics can withstand 250 degrees Celsius for a long time; Kaiao Si is a pre-oxidized fiber, which is of poly occurs not completely carbonized polyacrylonitrile fibers (which may have a fire resistance of the fiber) is obtained, and can stop the chemicals, heat radiation and molten metal, and has good thermal stability, carbonized polyacrylonitrile at 300 degrees begins to decompose, but it is only when the temperature reaches 550 degrees of natural decomposition of polyacrylonitrile fabric, protective clothing, to a short exposure at high temperatures.
