What is the difference between PP filter and PE filter? PP filter element
and PE filter element are both commonly used filter elements in water treatment. Both filter elements are white. If the specifications are the same, it is difficult to distinguish which is PP filter element and which is PE filter element with the naked eye. Is there any way to quickly distinguish it? The PP filter element adopts the melt-blown process, and the PE filter element adopts the sintering process. In terms of hardness, the PE filter element is harder than the PP filter element. You can press it by hand. Let me introduce it to you. their specific differences. Features of PP filter element: Polypropylene PP filter element is a tubular filter element made of non-toxic and odorless polypropylene particles after heating, melting, spinning, pulling and receiving. If the raw material is mainly polypropylene. It can be called PP meltblown filter element. It is not only used in large quantities of water purification. It also has excellent chemical compatibility and is suitable for filtration of strong acids, strong alkalis and organic solvents. Strong dirt holding capacity, long service life and low cost. (1) The pore size of the filter element is dense and uniform, and the filtration efficiency is high. Since the particles will bridge in the filter element pores, the particles smaller than the pores can also be blocked, and the filtration efficiency is above 98%. (2) It has high cleanliness and no pollution to water quality. (3) Corrosion of chemical reagents such as acid and alkali and organic solvents. (4) The strength is high. When the pressure difference between the inlet and outlet of the filter is 0.4mpa, the filter element will not be deformed. When the pressure is high, it can be lined with polypropylene brackets (or immortal steel skeletons) (5) The price is cheap, and it is mostly used for first-stage filtration, one-time use. Features of PE filter element: 1. Ultra-large flow rate: high porosity (60%) Ensures a larger fluid flow per unit area; 2. Smooth outer surface: smooth outer surface, impurities are not easy to stick, and backwashing is easy and thorough; 3. Strong anti-fouling ability: the filtration accuracy of small outside and large inside makes impurities cannot remain in the filter element. , the sludge can be pressed to 70% of the water content; 4. Excellent cost performance: the filter element has excellent comprehensive performance and low price, and is suitable for water treatment, reclaimed water reuse, chemical product filtration and other working conditions with large flow. 4. Corrosion resistance of strong acid and alkali, and resistance to the dissolution of organic solvents; 5. Excellent strength and wear resistance ensure its service life; 6. The surface of the external light makes it difficult for impurities to stick; 7. Backflushing and backflushing are easy to repeat Use; 8. Good toughness, the filter element is not easy to break; 9. There is absolutely no threshing phenomenon; 10. Strong pressure resistance.
