The microporous filter material of the filter bag cannot accurately measure the diameter, how to determine the precision?

The raw material of the surface filter sieve can accurately measure the obtained diameter value at the same time, that is, the precision of the filter system. The microporous filtration material of the filter bag cannot determine the exact value, so the traditional calibration method is to calibrate a raw material with corresponding net weight, thickness and permeability to the rated value precision. Each raw material distributor has different specifications, but each raw material should have rigorous industrial production characteristics and complete data testing. Therefore, when the dust removal bag brought by your dust removal bag dealer is calibrated to 5um, the precision is only relative filtering precision, which does not mean that the dust removal bag accuracy is 5um in diameter.

It should be understood that the service life of the filtration system is closely related to the breathability of the material. If the air permeability of the raw material is low, the initial pressure difference of the dust bag application is small, and the working pressure is relatively slow. Of course, the service life of the dust bag is longer, and vice versa. In addition, the manipulation of the surface treatment process will also directly affect the service life of the dust bag. Liquid felt is a harsh surface calendering process. If the perfect surface smoothness is pursued too much, the melted chemical fibers will block the safe passage of filtration, which will of course reduce the availability of the solution, increase the loss of the filtration system, and finally reduce the service life of the filter bag. Therefore, the smooth appearance of the textile does not necessarily mean that the application effect of the textile will be very good.
