PPS high temperature resistant needle-punched filter felt

     PPS filter felt is one kind of main high temperature resistant filter mediums. Our factory have selected the polyphenylene sulfide (pps) fiber from America and Japan and followed the other producing technology of high temperature resistant filter felt to produce it, which is the most suitable for the following occasions:1.Favorable temperature resistance melting point 285Degrees Celsius,working temperature 190Degrees Celsius, instantaneous operating temperature232Degrees Celsius,limited oxygen index 34~35;2.Be suitable for the oxygen content below 15%;3.Oxide containing sculpture in the fuel or flue gas, now it has been proved that it was the fiber of anti-acid, alkali, abrasion and chemicals;4.Containing moisture in the flue gas;5.under the condition of 190Degrees Celsius~232Degrees Celsius operating modes. PPS fiber has strong integrate retentively and internal chemical resistance, which keeps good filter efficiency in the harsh environment, and reaching longer using life. PPS filter felt is the ideal filter material for the pulsate dedusting precipitator in the coal fired boiler, waste incinerator, powder and coal dust collecting in the electric power plant.
