PPS filter felt I choose polyphenylene sulfide (PPS) fiber produced by the United States, Japan andother countries, according to other high temperature resistant filter felt Production, production and processing of filter material is one of the main varieties of high temperature filtration material. Thethe PPS of acupuncture filter in the following occasions in performance excellence.
1, the working temperature of 170 ° C, short-time working temperature of 232 ° C, the melting point of 285 ° C, limiting oxygen index of 34 to 35.
2, the oxygen content in the 15% or less of the occasion can be applied.
3, the fuel sulfur or flue gas sulfur oxide has proved its acid corrosion resistance, the strong fiberchemical resistance.
4 occasions, with moisture in the flue.
Mining conditions at the temperature of 190 ℃ ~ 232 ℃, gas cloth ratios of up to 5:1 for line cleaning line cleaning and air-to-cloth ratio of 6:1, PPS filter bag has excellent performance record.
PPS fibers having strength to maintain the integrity and inherent chemical resistance, and a good filtration performance can be maintained in the harsh environment, and to achieve the desiredservice life. Pulse cleaning dust collector filter coal-fired boilers, waste incinerators, power plant fly ash dust collection, PPS filter felt filter material.
