PPS Needled Felt with PTFE membrane

PPS fiber can keep intensity completely and bear chemistry nurturing inherently

PPS fiber can keep intensity completely and bear chemistry nurturing inherently, keep good filtration performance among the abominable environment, reach ideal service life. In coal boiler, rubbish incinerator, power plant of fly ash filtering of pulse clear dust catcher PPS filter felts are an ideal filtration material.

PPS filter felt is one of the main filter materials able to bear the high temperature according to processed of production technology and artificial material of other high-temperature filter felt. Features: 190centigrade of working temperature, 232centigrade of short-term working temperature, 285centigradeof melting point, and oxygen index of limit 34-35 Oxygen content is in 15% or following occasions are applicable. Fuel includes sulphur or containing sulphur oxide in the flue gas, is proved to the fiber of resist acid and alkali corroding resist chemistry very well Flue gas including moisture occasions. Under 190-232centigrade 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.
