Test methods for performance of the dust bag

1.Visual inspection: Gill pores, defects, spots, jumper, break, etc.

2.physical performance: dust bag the mass per unit area, depth, amplitude, woven organization, fabrics, non-woven fabric density, porosity, etc.

3.mechanical properties: dust bag, breaking strength, elongation, bag weft load elongation, the bursting strength of the filter, etc.

4.dust filter features: drag coefficient of static dust removal efficiency and dynamic efficiency, filter dynamic resistance, resistance coefficient and dust removal rate of regeneration.

5.special features: such as high temperature resistance, corrosion resistance, electrostatic properties, hydrophobicity etc.
