Dust filter bag is a kind of high efficiency dust filter material, with good ventilation performance, high dust removal efficiency, and a certain degree of acid and alkali resistance and heat resistance. In the weaving process, a multi-sided brushing is used to increase the thickness of the fabric and it is flexible. The dust removal effect is very good and the dust removal rate can reach 99.99%.
For the dust filter bag, the verification and test contents are as follows:
1. Appearance test: puncture, blemishes, dark spots, jumpers, broken wires, connectors, etc.
2. Physical properties: such as the mass per unit area of the bag, the thickness, the amplitude, the organization of the woven fabric, the density of the fabric, the bulk density of the nonwoven fabric, and the porosity.
3. Filter dust characteristics: such as drag coefficient, static dust removal efficiency, dynamic dust removal efficiency, dynamic resistance of filter material, regenerative resistance coefficient and dust stripping rate.
4. Mechanical properties: such as the breaking strength of the dust filter bag, the elongation at break, the elongation and the load in the warp and weft direction of the bag, and the bursting strength of the filter material.
5. Dust filter bag special features: such as temperature resistance, corrosion resistance, electrostatic properties, hydrophobicity and so on.
