PPS acid and alkali resistant needle felt is a new type of high temperature resistant filter material produced by the production process of other high temperature resistant needle felts by using the polyphenylene sulfide chemical fiber produced by DuPont and Teijin, and the PPS has complete strength retention. Sexual and intrinsic chemical resistance, good filtration performance in a harsh environment, and the ideal service life, PPS acid and alkali needle felt in the following applications:
1, the working temperature is 180 ° C, instantaneous 200 ° C;
2. Oxygen content below 15%;
3. The flue gas contains sulfur oxides;
4. The dusty gas in the flue gas is wet.
