Material:
polyester felt are made of 100% filament polyester fiber.
Polyester fiber needled felt normal temperature is used non
woven needle-punched process using fiber staggered, space
distribution uniform fine fiber cloth, polyester staple fiber
with polyester twisted yarn production by needled felt hot,
singeing, or coating on the surface, such as post-processing,
make its surface level off is smooth, not easy to be blocked
by dust, the filter material porosity, permeability is good,
use very extensive, strong resistance to chemical stability,
not only can filter room temperature gas, and the filtering
with acid and alkali corrosive gas, and can filter, oil
filter, water is the normal temperature condition,
solid-liquid separation in areas such as the ideal filter
material.
Advantage:
Breaking Elongation is less than 20% for MD and 40% for
CMD,low dry shrinkage, can work well in the 130 deg C. the
material is cheaper than other material, so widely used in a
lot of bag house system.
Polyester 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.
