PPS needle felts PPS needle felts

  • Product Description
  • Technical Data Sheet

 PPS high temperature resistant needle filter  is produced with the production process of polyphenylene sulfide fiber felt by the pressure of light, heat and water repellent treatment.
1, Good hydrolysis resistance, has excellent acid and alkali corrosion, sulfur or sulfur oxides in flue gas fuel can be used; 
2. In the flue gas oxygen content of less than 14% of the collection can be used in dust, but the temperature should be lowered accordingly; 
3.Long time working temperature of 190
, short-time temperature is 220 , the melting point of 285 ;
4.Suitable for dedusting of flue gas humidity, high concentration, strong adhesion and chemical composition of PPS filter ,remaining strength and chemical resistance, can maintain a good filter performance in harsh environments, is the first choice of filter material of coal-fired boilers, waste incineration power plant and city dust processing, can also be used in alumina plant powder for dust purification.
