Our company produces the non-woven needled felt filtration material and filtration bags made of P84 fiber. The materials is used for the dust collection in the industry environment of outlet if cement kiln and waste incineration. The product has the following advantages:
P84 fiber has irregular shape section like leaves, therefore, it has about 80% more surface area than that of the fibers with regular round round section. That ensures the high efficiency of filtration and prevents the dust to infiltrate deeply into the filtration material. The material can be used under the temperature of 240℃ (long-term) and 260℃ (short-term), suitable to be used with PH5-9. It is on of the few materials that can stand such high temperature. The fiber has good hydrolysis stability, LOI(limit oxygen index) of it is 38%. The filtration bag is suitable for long time working with high amount of dust and chemical load conditions. The filtration materials is the best choice for the dust collection in the industry environment of outlet of cement kiln and waste incineration.
Three proofing of the non-woven needled felt product has good dimensional stability, high strength, long service life, etc, so it also has the unique advantages such as small resistance, easy to clean. In mineral processing, coal, petroleum, chemical industry, etc, need to filter tiny particles and guarantee, three proofing needled felt far superior performance than the traditional woven filter.
According to special conditions and characteristics of dust, cement by adding compound conductive material to reduce the static electricity, effectively reduce friction produced by electrostatic: on the basis of ordinary including anti-static carpets by special chemical treatment, increase the “waterproof, prevent oil” function, three proofing functional fiber needled felt after nano waterproof, prevent oil treatment has the “lotus leaf effect”, after contact with water, oil filter bag surface is not easy to soak, solve problem of the condensation, paste bag bag anti-static, the filter, condensation, high dust removal efficiency, high porosity rate, gas filtration resistance is small, suitable for the occasion of higher temperature.
