Material：
polyester felt are made of 100% filament polyester fiber.
Polyester needle-punched felt can be supplied with surface finishes selected for the application. Confirm the fiber and scrim construction, air permeability and finish with the applicable product specification. Dust release, pressure drop and chemical compatibility depend on the process and cleaning system; gas and liquid filtration duties require separate suitability review.
Feature:
1. Maximum continuous operating temperature: 130°C.
2.the max surge is 150 deg c.
3. Review acid, alkali and moisture exposure for the intended process; polyester compatibility depends on operating conditions.
4.Mean Air Permeability: 10-15 m3/m2/min@12.7mmH2O
Available Finish: singed,calendar,PTFE membrane,W/O
Advantage:
Listed breaking elongation is less than 20% in MD and 40% in CMD. Confirm the test method and dry-shrinkage data for the supplied grade. The maximum continuous operating temperature is 130°C; actual suitability also depends on moisture and chemical exposure.
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.
Application:
Potential applications include mineral processing, cement, metals and wood-processing dust collection. Confirm process compatibility before selection. Food or pharmaceutical applications require review of the applicable product documentation.
