Introduction
pps filter bag scientific name polyphenylene sulfide pps, specific gravity 1.38g/cm3, melting point 285 ° c, breaking strength 5.0g / d, limiting oxygen index 34. it is a crystalline high-performance thermoplastic engineering plastic with many properties such as heat resistance, chemical resistance, flame retardancy, etc. the pps operating temperature is 160 ° c – 200 ° c. aolan pps has excellent heat resistance, excellent acid and alkali resistance, excellent hydrolysis resistance, and is also a good flame retardant filter material with extremely high thermal stability. however, pps has poor oxidation resistance and is prone to oxidative corrosion.
Advantage
- working temperature 170 ° c, short-term working temperature 232 ° c, melting point 285 ° c, limiting oxygen index 34 ~ 35.
- it can be used when the oxygen content is 15% or less.
- the sulfur-containing or sulfur-containing oxides in the flue gas have been proven to be resistant to acid-base corrosion and chemical resistance.
- the occasion of moisture in the flue.
- under the temperature of 190 ° c ~ 232 ° c mining conditions, gas cloth ratio of up to 5:1 to do line cleaning and air cloth than 6:1 for offline cleaning, pps filter felt dust filter bag has an excellent performance record.
