For the wear of dust, the choice of filter bag should pay attention to three points
Chemical fiber is better than glass fiber, expanded glass fiber is better than general glass, fine, short, curly fiber is better than thick, long, smooth fiber.
In the felt should be needled to strengthen the crosslinking between the fibers, the best fabric with satin fabric, fabric surface pull is also to improve the wear resistance measures, but felt, satin fabric and pile filter bag will increase the resistance value.
(3) for ordinary filter material surface coating, pressing and other post-treatment can also improve the wear resistance. For glass fiber filter bag, silicone oil, graphite, polytetrafluoroethylene resin treatment can improve the wear-resistant folding. However, when the film coated filter material is used in the condition of strong abrasion, the film will be worn out prematurely and lose the film coating effect.
