The dust bag in the process should pay attention to the dust filter bag sewing methods to determine the size of a good specification. Dust bag fabric and design should be the pursuit of high efficiency filter, easy-to-dust stripping and durable effect. The selection of the dust bag is essential, it has a direct impact Precipitator effect, select the select the optional dust bag from the following aspects: the gas temperature, humidity, and chemical; particle size; dust concentration; filtration velocity; clear dust way. The dust bag before leaving the factory should do the following inspections: 
 An appearance inspection: puncture defects, spots, jumpers, disconnection, and other joints. 
 Physical properties: such as sack mass per unit area, thickness, ranging from woven tissue, fabric density, non-woven fabric bulk density, porosity, etc.. 
 Dust features: such as drag coefficient, static http://www.hjztcc.com/ state collection efficiency dynamic collection efficiency, the dynamic resistance of the filter regeneration drag coefficient and dust peel rate. 
 Mechanical properties: dust filter, such as the breaking strength, elongation at break, latitude and longitude of the cloth bag to load elongation rate, the filter of the bursting strength and so on. 
 Dust filter special features: such as temperature resistance, corrosion resistance, static characteristics, hydrophobicity, etc..
