P84 high temperature resistance P84 PTFE filter bags 260 degree sleeves dust filter bags
Riqi produces p84 high-temperature needle-resistant filter felt which polyimide fiber produced by Austria LENZING Company. The filter material has the following three characteristics:
- significant temperature resistance; operating temperature 260ºC, but with safe space to cope with downtime and accidents.
- good chemical resistance; the filtration value of p84 filter bag on acid waste dust has been confirmed in the past ten years of garbage incineration.
- Low back washing pressure and high efficiency of breaking away dust cake, The p84 characteristics are significant because of the fineness of the fiber itself, and the irregular fiber cross section increases the fiber surface area to the maximum and provides a lot of tiny pores to make the surface filtration effect better than the depth filtration.The dust only stays on the surface of the filter felt and does not penetrate into the filter felt. Therefore, the reverse washing pressure is small and the efficiency of cake stripping can be improved significantly. It has excellent fine powder collection efficiency and small working pressure difference.

Application: p84 filter material has gained rich application experience Riqi produces p84 high-temperature needle-resistant filter felt which polyimide fiber produced by Austria LENZING Company. The filter material has the following three characteristics:in gypsum plant, cement plant, garbage incinerator, liquid fluidized bed boiler, coal-fired boiler and so on.
RIQI company has grown up to be one of leading manufacturer on dust filtration&spare parts in China.We have imported filter needle felt production line ASSELIN from France and we can produce very good quality non-woven products according customer's requirment.
Based on 8 needle felt production line ,our annual production ability can achieved 20,000 square meters per day . We can produce a large range of various filter fabric, such as polyester filter fabric, Acrylic filter fabric, Fiberglass filter fabric, PPS filter fabric, Nomex ,P84 ,PTFE ,woven filter fabric and so on.
The most important thing is that we introduced German high technology to develop the first filter bag production line in China. Which help most filter bag production factory save a lot of human lab our cost but promote the work effection . The advanced technology and simple operation way of automatic filter bag production line has won a lot of customer's praise.
