Introduction to the principle of PP cotton filter cartridge

PP cotton filter cartridge is made of polypropylene resin as raw material, which is wound and bonded by the fiber itself. The outer layer of the filter catridge is coarse fiber, and the inner layer is loose. It is filtered from the outside to the inner layer. The closer it is to the inner layer of the filter cartridge, the smaller the aperture is, the higher the filtering accuracy is.
