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.
