P84 flue gas is mainly used in asphalt mixing, cement kiln, drying, combustion, smelting, various industrial kilns, coal-fired boilers and waste incineration process of purification, and widely used technology in the emission concentration of.
P84 bag is a kind of flame retardant, high temperature stability of fiber filter material, at the temperature of 240 DEG C under the condition of mechanical P84 polyimide fiber filter does not change, the highest temperature can reach 260 DEG C. P84 fiber filter material without melting temperature, a natural blonde. Fiber filter P84 polyimide fiber filter is not hygroscopic (in the 65% relative humidity conditions about water content 3%).
In addition, because the P84 fiber is special (Ye Zixing) cross section structure, with large filter surface area, has the excellent filtering performance, so the P84 fiber has often been implanted filter surface (dust facing surface in order to improve the performance of filtering material).
P84 material is made of polyimide fibers by Acupuncture and its characteristic, because of fiber fineness and significant. The P84 filter has the following advantages:
Significant temperature resistance: can be used for a long time at the temperature of 260 DEG C, short-time working temperature can reach 280 DEG C
Good acid and alkali resistance, oxidation resistance, some hydrolysis resistance.
Low pressure and high effect; polyimide with irregular fiber cross section, the P84 filter has a large surface area, provides more surface micro pores, the filtering effect is better than depth filtration so much dust only stay in the filter mat and not into deep, the backwash pressure is small, the efficiency of removing filter cake. Can be obviously improved, with excellent powder collection effect, at the same time to what industry of small pressure difference.
P84 filter is widely used in waste incineration flue gas purification and dust recovery, thermal power, steel, metallurgy, chemical and other industries.
