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.
