Use protective clothing an important component of the outer fabric flame retardant, is a polymer material can effectively reduce post- combustion properties of the material, Cangzhou sea solid security protection Technology Co., Ltd. said: flame retardant mainly used to reduce the material in flames flammability , flame propagation speed slows down , the flame was removed soon after extinguishing material can no longer smoldering . Therefore, fire retardant clothing is essential substances.
Flame retardant classification can be divided from the reaction mechanism and the reactive additive ; From the chemical structure can be divided into organic and inorganic flame retardants . The most commonly used flame retardant is a group of the Periodic Table of boron and aluminum Ⅲ , Ⅴ group of the nitrogen , phosphorus, antimony , bismuth , the Ⅶ family elements such as chlorine and bromine based on certain compounds .
Carbon fiber
Carbon fiber is a carbon content of more than 90% of the high strength , high modulus fibers. As the carbon fiber is mainly composed of carbon , so it does not burn , chemical stability , corrosion resistance; carbon fiber proportion of small thermal expansion coefficient, thermal conductivity , high temperature mechanical properties of small changes ; also has good electrical conductivity. Made of carbon fiber composite materials , high strength , impact resistance , light weight, widely used in aerospace , aviation, automotive and so on.
Cotton flame retardant fiber
Cotton fiber is a phosphorus flame - retardant ammonia , cross-linked resins , softeners and other materials, special processing of the cotton fiber finishing, having excellent flame retardant , washable , breathable, breathable, soft, non- toxic harmless, no skin allergies and other properties, is the second generation of flame-retardant personal protective clothing fabrics . The product is applicable to all industries protective equipment , and may be needed to give the fabric with waterproof and breathable , UV and other properties.
Polybenzimidazole fiber (PBI)
Polybenzimidazole fiber is a typical heterocyclic polymer heat-resistant fiber , which is composed of diphenyl isophthalate and diphenyl four amine polycondensation , the available solution spinning spinning shape. PBI does not burn in air , limiting oxygen index of up to 38-46,550 ℃ high temperatures without melting , do not smoke , do not shrink or rarely shrink the fabric remains intact , soft, good chemical resistance , moisture regain of 13% -15%, taking good , comfortable to wear.
Aromatic polyamide fibers
High temperature resistant aramid fibers have good thermal stability , excellent chemical and physical properties, soft and tough , wear-resistant , flame retardant in flames , with self-extinguishing, good resistance to aging , resistance to most organic solvent and acid corrosion. Mainly used for making explosive environment protective clothing , fire suits and spacesuits . Due to its outstanding performance and broad market , countries have carried out research and development .
