Round PPS Dust Filter Bag Bag House PPS Bag Dust Collector PPS Felt
Bag
1. Specification
PPS(polyphenylene sulphide) polymer is formed by reaction of
sulphur with dichlorobenzene. PPS has both high temperature
resistance (190℃) as well excellent acid and alkali resistance, although it can be
degraded in highly oxidative environments. PPS fiber needle felt is
made of imported PPS fiber which produced by Japan, it is the
leading varieties of the high temperature fiber material, PPS
filter bag perform excellent in the application of the following
situations.
1) The working temperature is up to 190℃,short term working temperature 210℃, the melting point of 285℃, the limit oxygen index 34-35
2) The oxygen content with 10% or below can be used
3) The place of flue gas containing moisture
PPS has the strength to keep the integrity and intrinsic chemical
resistance, can maintain a good performance in the bad
environments, and achieve the ideal life. PPS bag is the ideal
material of filter coal boiler, incinerator ash, dust processing
and others pulse dust collectors.
