Q:What need to test when use the dust filter bags ?
A:For dust filter bags , content verification and testing needs as follows : 1. Visual inspection : puncture , defects, spots, jumpers, disconnection, and other joints. 2. Physical properties: dust filter bags as mass per unit area , thickness, amplitude , woven tissue , fabric density , non-woven fabric bulk density , porosity and the like. 3. Mechanical properties : such as dust collector filter bag breaking strength, elongation at break , bag of latitude and longitude to the load elongation , bursting strength of filter media . 4. Dust features: such as the drag coefficient , static dust removal efficiency , dynamic collection efficiency filter dynamic resistance , resistance coefficient and dust stripping regeneration rate . 5. Special feature: such as temperature resistance , corrosion resistance , electrostatic properties , hydrophobicity and the like.
