Cement processing plant polyimide p84 dust filter bag
P84 high temperature resistant needle-punched filter felt is INSPECFIBERS (polyimide fiber) produced.
It is a high-efficiency filter material with high temperature resistance and acid and alkali resistance developed by other non-woven fabric production process.
At present, there are only a few manufacturers in China that independently develop, design and produce the filter material.
P84 filter material has high temperature resistance (can be used for a long time below 260 °C), and has good chemical resistance.
It has a very significant filtering effect on dusty gas with acid and alkali, making it in the waste incineration industry. It has highlighted higher dust removal efficiency in the waste incineration industry.
