2017-03-28
At this time, some bag filter bags require film. The biggest advantage of the membrane filter bag is to achieve the surface filtration, the principle is through the smooth surface of the microporous expanded PTFE film dust trapped in the surface of the filter bag, and no longer in the filter material inside the formation of dust layer, so that the real surface filtration. And because of the smooth and hydrophobic characteristics of PTFE, the dust is not easy to adhere, the effect of stripping and cleaning is very good, and it also has the characteristics of high temperature resistance and corrosion resistance.
It can be seen that the coated filter bag plays a major role in the process of filtering and cleaning ash. However, the thickness of this layer of coating is only a few microns, which is a veritable "thin" film. Therefore, in order to ensure the quality of the finished product of the film filter bag, the production of the filter bag must have a special process to ensure that the film is not damaged. And exquisite sewing technology is the guarantee of high-quality film-coated filter bag.
