Four - proof punched felt
High-Performance Mixed Conductive Punched Felts
Mixed conductive punched felts are subject to blending of polyester staple fiber and carbon fiber and made through opening,carding,mesh placement,pre-punching,high-speed upper and lower punching,singeing,calendaring and heat setting.It can greatly improve conductive performance of filter bag,prolong life of filter bag and reach better service effect
Punched Polyester Felts Under Normal Temperature
Polyester-based (PET-based)punched filter felts are produced with first grade polyester staple fibers as raw materials.In addition to unique advantages including high porosity,good air permeability, high dust collection efficiency,long service life and other aspects possessed by common felt-type filter cloths,due to medium high temperature resistance grade,instantaneous temperature to reach 150℃, medium acid and alkali resistance,it has very excellent abrasive resistance.Hence,it is the mostly frequently used category in felt-type filter materials.In terms of surface treatment,singeing,calendar- ing or coating and other treatments can be adopted according to different requirements of working conditions,
