Dust filter bag filter material is good or bad, how to spot checks?
5, film coated media: detection of film firmness.6, filter material dust removal performance: such as filter resistance coefficient, static dust removal rate, dynamic dust removal rate, filter media dynamic resistance, coefficient of regeneration resistance and ash cleaning efficiency.
3, filter material physical indicators: such as filter media thickness, uniformity, quality, permeability, amplitude, fabric weave, woven fabric density, non-woven fabric volume density, porosity, etc..4, special function characteristics: Determination of its temperature resistance, heat resistance, abrasion resistance, flame retardancy, anti-static characteristics, acid, alkali, corrosion, hydrophobic and so on.
Filter bag is the filter core of the dust collector, its quality directly reflects the dust removal efficiency and service life. In order to ensure the quality of the filter bag, the filter bag of the filter bag should be checked to determine its performance to the standard. The filter material needs verification and testing:1, filter material appearance: observe whether there are jumper, defect, puncture hole, black spot, joint, broken line, etc..2. The mechanical properties of filter media: check the breaking strength, elongation at break, load elongation of the warp and weft direction, and the bursting strength of the filter bag, etc., whether it conforms to the standard or not.
