Details

The P84 needle punched felt produced by our company is made of polyimide fiber P84 produced by Austria Lenzing Inspec Fiber company, similar products and French Kernel Kernel fiber. The material has excellent high temperature resistance, chemical corrosion resistance and wear resistance. The high specific surface area and cross section of P84 fiber give the product good dust collecting performance. P84 fiber can be blended with other fibers or combined with high-performance fibers such as PTFE, PPS, PMIA and PES to form a composite structure, play a synergistic effect, and product life is very long.

* composite filtering materials may be formed with other fibers and base cloth according to the actual working conditions

【P84 needled filter felt】

Matters needing attention

1. Before entering the filter bag, the best desulphurization treatment is carried out.
2. The content of nitrogen and oxygen compounds NOx < 600mg/Nm3;
3. The content of sulphur oxide SOx < 600mg/Nm3;
4. Oxygen content O2 < 22%, water content H2O < 35%.
