Advantage:
PPS fiber needled felt bag surface smooth degree of dynamic resistance of the bag has very big effect. Bag at the beginning of the resistance of porosity depends on the bag itself, and the running resistance is many times larger than the early resistance. Running resistance depends on the degree of the smooth surface of the filter material, ash removal effect, etc. General hope bag in the filter efficiency, guarantee the same air quantity is bigger, the better, the resistance is lower, the better, because it can save a lot of energy. In the use of air blow dust precipitator, at the same pressure, the same air volume of air dust, selection of large quantities of breathable weaving thing to do when the filter bag is better than the effect with less breathable weaving. Therefore, in the guarantee filter material to achieve high filtration precision, how to improve the bag of porosity and increase the degree of the surface is smooth, reduce dust adhesion, reduce the running resistance is filter material factory should first research topic. Our factory developed resinification smooth surface finishing needled filter felt bag, its porosity than common calender finishing above 50%, higher than that of filter material and smooth surface is much greater than the pressure more smooth finish.
