Our company uses INSPEC FIBERS polyimide fiber produced by Austrian company LENZING to produce P84 high-temperature resistant needle punched filter felt, which is a new high-temperature resistant variety produced under the guidance of a professional foreign company. We are the first domestic production enterprise to mass produce this filter material. The characteristics of P84 dust removal bag are significant due to the fineness of the fibers themselves, and the irregular cross-section of the fibers increases the surface area to the maximum, providing many small pores to make the surface filtration effect better than deep filtration. Dust only stays on the surface of the filter felt and cannot penetrate into it, so the backwash pressure is low and the efficiency of filter cake bounce off is significantly improved, with excellent collection efficiency of fine particles and small operating pressure difference. Suitable for coal-fired boilers, liquid bed boilers, waste incineration, asphalt plants, cement plants, waste incinerators, etc.
The superior performance of P84 filter material:
① Cost saving: Low pressure drop reduces costs
② Filtration efficiency: Suitable for the strictest environmental standards, temperature resistance (up to 260 ℃/500 ℉)
③ Low failure rate
④ Longer working life
⑤ Excellent chemical stability (strong acid and alkali resistance, suitable for applications with pH 2-12)
⑥ Suitable for a wide range of applications
P84- Special cross-section:
The trilobal cross-section is a characteristic of P84 fibers, which is a treasure compared to other circular fibers because it increases the fiber surface area by 80%, resulting in:
① Unparalleled filtration efficiency
② Perfect cleaning effect
③ Due to the absence of dust or fine stone chips piercing into the felt, there is the lowest possible pressure drop
Application areas of P84 needle punched filter material:
Good acid and alkali resistance, stronger temperature resistance (260 degrees) make it suitable for use in harsh working conditions; Widely used in industries such as waste incineration, thermal power generation, steel, metallurgy, and chemical engineering.
