PI Filter Bags also called Polyimide or P84 Filter Bags , P84 is a register Logo made by Evonik from Austria . Polyimide and PI is made from China . The P84 Filter bags have excellent abrasion , fire resistance and high temperature , it is widely used in Cement Kill and waste incineration bolier dust collector .
Feature:
1. Working Temperature is 240 ~ 260 degree C
2. Due to the leaf-shaped cross section of P84 fiber , It’s 80% increase in filtration area than other material
3. The properties of Hydrolytic and Oxidation resistance are not very good. The water vapour content less than 35%Vol and O2 content less than 16%Vol.
4. Oxysulfide will shorter the service life of P84 Filter bags, the suggestion content of oxysulfide should be less than 700mg/Nm3; the waste incinerator should have the desulfurizing unit.
Application :
1. Cement Kill
2. Waste Incineration Bolier
Physical Properties :
