P84 polyimide high temperature filter bag
Waste incineration industry P84 filter bag is a flame retardant, temperature stable fiber
filter material, at 240℃ temperature conditions, the mechanical P84 polyimide fiber filter
material will not change, the maximum temperature of up to 260℃. P84 fiber filter
material has no melting point temperature and is a natural golden color. P84 polyimide
fiber filter material is not hygroscopic fiber filter material (about 3% water absorption at
65% relative humidity conditions).
In addition, because the P84 fiber is a special-shaped (leaf type) cross section structure,
with a large filter surface area, has excellent filtration performance, so P84 fiber is often
implanted in the filter surface (dust surface side to improve the filtration performance of
the filter material).
Waste incineration industry P84 filter bag is mainly used in asphalt mixing, cement kiln,
drying, burning, smelting, various industrial kilns, coal-fired boilers and waste incineration
process of flue gas purification, and widely used in high emission concentration requirements
of the process.
