INTRODUCTION

The properties of the PTFE filter material in the dust removal bag are excellent, and the advantages are obvious, such as high temperature resistance, acid and alkali resistance, hydrolysis resistance, oxidation resistance, etc. The better temperature is 260 degrees. However, it also has certain disadvantages, such as: difficult to comb, low filtering accuracy, and slightly poor wear resistance.

2. Why the filtering accuracy of the PTFE filter material in the dust filter bag is low. Because it is made by the membrane splitting method, the fiber fineness is uneven, and the fibers are flat fibers. The fiber diameter is a few microns low and hundreds of microns high. The diameter of conventional fibers is generally ten microns. The smaller the diameter, the finer the fiber, the larger the specific surface area, and the higher the filtration area.

4. P84 dust bag filter material has good high temperature resistance and acid resistance. The disadvantage is that it is resistant to alkalis, not hydrolysis, and the best temperature is 240 degrees. However, it has a three-lobed or cylindrical shape, the filtration accuracy is high, and the price is too expensive.
