Polyester needled filter mats are produced from Dahua Polyester Staple Fiber. The polyester needle punch felt has the advantages of high air void height, good air permeability, high dust collection efficiency and long service life, in addition to the ordinary felt filter cloth.
Introduction
Polyester needled filter felts are produced from Dahua Polyester Staple Fiber. Polyester needle felts have the advantages of high voids, high air permeability, high dust collection efficiency, long service life, etc., besides the characteristics of ordinary felt filter cloths, due to its moderate high temperature resistance, instant up to 150°C, acid resistance, and resistance Alkali is suitable for its characteristics, and it has very good wear resistance, so it is the largest one used in the felt filter media. The surface treatment method can be singed, calendered or coated according to the different requirements of working conditions. All fabrics are woven with filament 1000D. After being finished, the finished product is shaped at a high temperature of 155°C. The surface is coated with Teflon. The effect of iron and steel flue gas dust removal is much better than that of other polyester materials. The service life is more than one year.
