The PP cotton filter produced by the PP filter cartridge machine is used as a pretreatment part of the reverse osmosis equipment, which can filter 80% of impurities. The quality of the pretreatment water directly affects the quality of the whole machine. Therefore, the PP filter produced by the PP filter machine The quality is especially important for ultrapure water machines.
When the PP filter core machine is used to produce the PP filter element, the polypropylene raw material is used. The PP cotton filter core has a uniform pore size and dense cloth, and the inner and outer dense filtration structure has the advantages of high filtration efficiency and acid and alkali resistance. The primary role is to filter impurities of different particle sizes. Since the principle of PP cotton filter is caused by tightening and swell, its aperture determines the filtration precision. In the case of passing water, the smaller the aperture, the higher the precision of filtration, which plays a vital role in the filtration of water impurities. Long-term impurity filtration simply blocks the filter element, so it is recommended to replace the filter element every 3-6 months.
The fiber density produced by the PP filter machine can be judged by the quality. The larger the standard filter element, the higher the density, the smaller the aperture and the better the quality. The better the tightening, the better the quality. The larger the tightening, the smaller the aperture and the better the filtering effect. In general, in order to improve the quality of the water flowing out, people will let tap water flow through many filter elements.
