P84 High temperature needle felt filter bags

P84 high temperature needle felt filter used by our company produced INSPECFIBERS Austria LENZING polyimide fibers, the foreign company under the guidance of professional production of new varieties of high temperature, is the first volume of the filter's manufacturer.The filter has the following three significant features: 1, significant operating temperature of temperature 260 °C, but the space to cope with security downtime and accidents and so on.2, good chemical resistance in the past 10 years, the refuse incineration has been proven P84 bag of acid and alkaline dust emission filter value. 3, low-pressure backwash and sludge cake removal efficiency of high-elastic properties for fiber itself P84 fineness significantly, more so because of irregular fiber cross-sectional surface area to the largest fiber to provide a lot of small pores to the surface effect of superior filtration in the depth filter.Only remain in the carpet dust filter could not penetrate the surface of the filter mat, and therefore the pressure against the small cake shells wash off with significant improvements in efficiency, with excellent fine powder collection efficiency and the operating pressure difference.In the asphalt plant, cement plant, waste incinerators, liquid-bed boiler, coal boiler, has a long experience of using the P84 filter.polyimide fiber fabric (P84) / glass fiber Ji Buke weight (g/m2) 450500550800850900 Thickness (mm) 2.12.32.52.52.83.0 permeability "( m3m2/min) 191512161310 breaking strength by the zonal 115012001300180018001800 650700800180018001800 elongation (%) by the <35 <35 <35 <10 <10 <10 weft <55 <55 <55 <10 <10 <10 rupture strength ( Mpa / min) 2.552.502.403.203.102.95 continuous working temperature (°C) ≤ 260 ≤ 260 short-term operating temperature (°C) 280280 Youyou acid alkali resistance of the wear resistance good good hydrolytic stability of an Early Post-processing manner and singeing hot hot hot hot and singeing or Teflon coating.
