Coal-Fired Boiler Dust Collection P84 (Polyamide) Bag Filter
The Discription of P84 (Polyamide) Filter Bag
The P84 (Polyamide) filter bag is a flame retardant, heat stabilized fiber filter. Under the condition of a 240 ºC temperature, the performance of P84 polyimide fiber filter does not change and it can hold a maximum temperature up to 260 ºC. P84 fiber filter has no melting temperature, was natural golden yellow. P84 polyimide fiber filter is not hygroscopic fiber filter (at 65% relative humidity, the water uptake of about 3%).
Further, since the P84 fiber is shaped (leaf type) cross-sectional structure, with a large filter surface area, has excellent filtration performance, so P84 fiber are often implanted filter surface (Ying dust side to improve the filtration performance of the filter ).
