Introduction of aramid filter bag
Aramid needle felt as one of the new high temperature filter media can be
continuous used at 200℃ working conditions, and keep performance no changed. Also, depend on the special technical process and material, it have
better filtration efficiency and service life.
Feature of aramid filter bag
Aramid has the advantages of acid and alkali resistant, high temperature resistance, high strength, wear-resistant, abrasion resistance, bending
resistance, heat resistance, fire resistance, insoluble, long working Iife etc.
Application of aramid filter bag
It is widely used many fields such as asphalt, cement, steel , non-ferrous
