② Working condition: temperature 190 degrees/instant 240 degrees, air permeability 150-250

③Features: good temperature resistance, acid and alkaline resistance, small resistance, high filtration wind speed, size stability, easy to clear ash, dust has a strong interception and blocking effect, and can quickly form a dust layer, 2 times dust collection. It has the advantages of chemical corrosion resistance, strength stability of more than 90% in PH 3-4 working conditions, good air permeability, dust removal rate of 99.99% and so on. Mainly used in asphalt mixing flue gas, iron and steel plant blast furnace, carbon black (white carbon black) tail gas, cement kiln kiln head, kiln tail, electric furnace high temperature, refractory kiln and coking flue gas and gas dust removal.

④Disadvantages: poor hydrolyzability, quickly hydrolyzed and damaged in the presence of water and SOx at high temperature, so it is not suitable for use under the conditions of water and SOx dust

⑤ Post-treatment: singeing, heat setting, calendering, can also be coated.
P84 high temperature resistant needled felt filter material
①Principle: By the polyimide fiber through acupuncture, its characteristics due to its fiber fineness and significant.

② Working condition: temperature 260 degrees/instant 280 degrees, air permeability 150-250

③Features: good acid and alkali resistance and oxidation resistance, a certain water solubility, low backwash pressure and high elastic desmusing cake efficiency, good air permeability and high filtration efficiency (low backwash pressure and high elastic desmusing cake efficiency: Polyimide with irregular cross section, and thus P84 filter material has huge specific surface area, provide more tiny pore, its surface filtering effect is better than that of depth filtration, only so much dust on the surface of filter mat and did not wear into the deep, the backwashing pressure is small, filter cake to play off to improve efficiency, excellent of micro powder collecting effect, At the same time, the operating pressure is low). Widely used in waste incineration, thermal power generation, steel, metallurgy, chemical and other industries of flue gas purification dust recovery.

Low backwash pressure and high elastic desslime cake efficiency: THE characteristics of P84 are notable because of the fineness of the fiber itself, but also because the irregular fiber cross section increases the fiber surface area to the maximum and provides a lot of small pores, so that the surface filtration effect is better than the depth filtration. Dust to stay on the surface of the filter felt and did not penetrate into the filter felt, so the backwash pressure is small and the filter cake elastic removal efficiency can be significantly improved, with excellent fine powder collection efficiency and small operating pressure difference.
