Several points should be considered in the selection of filter paper:
1. The effective area and effective area are large, that is to say, the filter paper has a large use area, a large dust capacity, a small resistance, a long service life and a corresponding increase in cost.
2. The finer the fiber diameter, the better the interception effect and the higher the filtration efficiency.
3. In the filter material, the binder content is high, the tensile strength of paper is high, the filtration efficiency is high, the shedding phenomenon is less, the dust on the bottom of the filter material is small, the resistance is good, but the resistance increases correspondingly.
