The acrylic fiber needled felt filtration materials produce by our company is made by imported raw materials. The product is used in the field with middle temperature conditions. It has good heat-resistance, and corrosion resistance. It is kind of flame-retardant fiber. Compared with the ordinary acrylonitrile, it can resist higher temperature. Its continuous working temperature is 130℃. Compared with polyester(PET) or other acrylonitrile fiber, it has superior resistance to alkali and, corrosive gas, such as SO2, O2, O3. It shows the good resistance to organic solvent, oxidants, organic and inorganic acid when the working temperature is below 125℃. It does not have hydrolysis reaction, therefore, it is important to use the material to replace polyester to make felt filtration bag using at low temperature and wet conditions with chemical corrosion.
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.
