PPS acid alkali resistant needle felt bag, also known as poly. At present, the Conex Nomex, Kermel and inorganic fiber glass fiber as raw materials produced by needle punched filter felt in the market of high temperature resistant needle punched filter felt in china. The physical property of organic fiber is better than that of inorganic fiber. Polyphenylene sulfide fiber in recent years is high temperature resistant organic fiber and a high function fiber, not only has high temperature, and other high temperature resistant fiber can not be more than excellent corrosion resistance.
The advantages of the needle punched felt in the treatment of the fiber of the sulfide are indicated in the following aspects:
1, good temperature resistance melting point of 285 degrees, continuous use temperature 190 degrees Celsius, instantaneous temperature of 230.
2, excellent corrosion resistance of poly sulfide fiber fiber in organic acid, inorganic acid, acid, oxidant and other aspects are better than Conex Nomex and Kermel fiber.
3, excellent flame retardant poly (LDI) of the fiber's polar index (34-35), the fiber is a kind of non combustible material. The fiber needle punched felt not only has high temperature resistance, but also has the unique property of corrosion resistance.
PPS needle felt cloth acid and alkali widely used in metallurgy, chemical industry, building materials, thermal power, waste incineration furnace, coal-fired boilers and other industries high temperature and harsh working conditions, is a kind of high performance high temperature filter material. Our selection of polyphenylene sulfide fiber produced in the United States and Japan, according to other high temperature resistant needled felt production technology, specializing in the production of polyphenylene sulfide (PPS) needled felt, product quality has reached the level of similar products in developed countries.
