PPS filter bag is a filter material made of polyphenylene sulfide (PPS) fiber and manufactured and processed according to other high-temperature resistant filter felt production processes. It is one of the main varieties of high-temperature-resistant filter materials. PPS needle-punched filter media has excellent performance in the following applications. PPS is also called polyphenylene sulfide fiber. PPS filter is a new type of high temperature resistant fiber developed in the United States and introduced to the market in 1983. The physical properties of organic fibers are significantly better than inorganic fibers. Polyphenylene sulfide fiber is another high-functional fiber among high-temperature resistant organic fibers in recent years. PPS filter bag not only can withstand high temperature but also has the unparalleled excellent corrosion resistance of other high-temperature resistant fibers.
The outstanding advantages of PPS filter felt bag made of polyphenylene sulfide fiber are shown in the following aspects:
1. Good temperature resistance. Melting point is 285℃, continuous use temperature is 190℃, instant use temperature is 230℃.
2. Polyphenylene sulfide fiber with excellent corrosion resistance is superior to Nomex Conex and Kermel fiber in terms of resistance to organic acid, inorganic acid, acid and oxidant.
3. The extreme oxygen index (LDI) of the excellent flame-retardant polyphenylene sulfide fiber is 34-35, and the fiber is a non-combustible substance. Polyphenylene sulfide fiber needle punched felt not only has high temperature resistance but also has unique corrosion resistance. It is widely used in smelting, chemical, building materials, thermal power, waste incinerators, coal-fired boilers and other industries under high temperature and harsh working conditions. It is a high-quality, high-efficiency, high-temperature-resistant filter material.
PPS filter felt bag product has a smooth surface and good air permeability, which reduces the labor intensity of dust collection bag cleaning dust during use.
