Performance Inspection and Testing of Dust Collector Bags
In the field of bag dust removal, what kind of dust-containing smoke can be treated by the bag filter depends mainly on the conditions of the chemical fiber itself used to make the bag. Therefore, it is necessary to know how to test the performance of the dust collector bag in order to select the most suitable dust collector bag. For the dust collector bag, the contents to be inspected and tested are as follows:
1. Appearance inspection: puncture, defect, black spot, jumper, broken wire, joint, etc.
2. Physical properties: such as the per unit weight of the dust bag, the thickness, the amplitude, the structure of the woven fabric, the density of the fabric, the bulk density of the non-woven fabric, and the porosity.
3. Mechanical properties: such as the resistance strength of the dust bag, elongation at break, the warp and weft load elongation of the bag, the bursting strength of the filter material, etc.
4. Dust filtration characteristics: such as resistance coefficient, static dust removal efficiency, dynamic dust removal efficiency, dynamic resistance of filter material, regeneration resistance coefficient and dust stripping rate.
5. Special functional characteristics: such as temperature resistance, corrosion resistance, electrostatic properties, hydrophobicity and so on.
