pps filter cloth with long sevice life 1.strong integrate retentively and internal chemical resistance. 2. longer using life.
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.It is the main product in our factory,which is the most suitable for the following occasion:
1).Favorable temperature resistance melting point 285C,,working temperature 190C,instaneous operating temperature 232C,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 190-232 of mining condition, air cloth proportion up to 5:1 are going to do clear dust on the line and it up to 6:1 to do clear dust out of line,PPS filter bag have excellent performance noted down.
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 collection in the electric plant.
