Where is the advantage of PP cotton filter element?

Among the various water filter elements, the PP cotton filter element stands out for no reason, which is inseparable from its advantages. Below, let us take a closer look at the advantages of PP cotton filter in combination with the actual situation. 1. It can remove all kinds of particulate matter in water. The water flows from the outside of the pp cotton to the inside and passes through layers of filtration. The closer to the inner layer of the filter element, the smaller the pore size, the higher the filtration accuracy. When particulate impurities pass through the pores of the PP filter element, bridging will occur. Even particles smaller than the pores can be blocked, thus removing various particulate impurities in the filtered liquid. 2. Multi-layered deep structure, large pollution holding capacity. The fiber of the outer layer of the PP cotton filter element is relatively thick, while the inner fiber is thinner. The outer layer of the boiler is relatively loose, and the inner layer is tight, forming a multi-layer gradient structure with a gradually tightening diameter. Each layer of this multi-layer structure can intercept and store impurities in the water, and when many layers add up, the dirt holding capacity will be large. 3. Large filtration flow and small pressure difference. The raw material of PP cotton, polypropylene fiber, relies on self-adhesive entanglement to form a three-dimensional tortuous microporous structure. It is different from the fiber distribution in traditional fabrics and carded nonwovens. It has a large specific surface area and a high Porosity. The large surface area and many small holes can allow water to pass through the PP cotton quickly, without too much difference in the height of the inner and outer water, so not only the filtration flow is large, but the pressure difference is also small. 4. It does not contain chemical adhesives, which is more hygienic and safe. Polypropylene undergoes melt-blown, traction, and receiving technology to make polypropylene fibers intertwined with each other through self-adhesion to form PP cotton filter elements of different shapes and sizes. Unlike other filter elements, the bonding of PP cotton filter elements does not require other materials. Because the chemical composition of PP is clean and meets food hygiene standards, it will not cause secondary pollution to the liquid to be filtered due to the material, and it is more secure to use. 5. Good chemical stability, resistance to acids, alkalis, organic solvents and oils. The chemical stability of PP cotton is closely related to its raw material polypropylene. The chemical stability of polypropylene is very good, except that it can be corroded by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to various other chemical agents. Because of this performance, pp cotton is used in various fields such as chemistry and electronics. 6. It integrates surface, deep, coarse and fine filtration. Due to the multiple advantages of PP cotton, it has the characteristics of large flow, corrosion resistance, high pressure resistance, and its cost is not very high. It is widely used in pure water, food and drinking water pre-filtration treatment, and RO machine penetration pre-filtration. Processing etc.
