Does the PP cotton filter really play a non-negligible role in the water purifier?

Does the PP cotton filter really play an important role in the water purifier? Because the water purifier can produce high-quality pure water, it is mainly determined by the filter element, and the PP filter element is the first-stage filter element of the water purifier, which plays a very important role in the water purifier, so Lvyuan Electronics Co., Ltd. briefly introduces The five functions of the PP cotton filter element are as follows: 1. Hygienic and safe Polypropylene is meltblown, pulled and received technology, so that polypropylene fibers are entangled with each other by 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 the food hygiene standards, it will not cause secondary pollution to the liquid to be filtered due to the material, and it is safer to use. 2. The purification effect of particulate impurities is good. The water flows from the outside of the pp cotton to the inside, and is filtered layer by layer. The closer it is to the inner layer of the filter element, the smaller the pore size, the higher the filtering accuracy. When the particulate impurities pass through the pores of the PP filter element, bridging will occur, and even particles smaller than the pores can be blocked, and more than 80% of the particulate impurities in the water will be filtered out at this stage. 3. Strong dirt holding capacity The outer layer of the PP cotton filter core is relatively thick, while the inner layer is relatively thin, the outer layer is relatively loose, and the inner layer is tight, forming a multi-layer gradient structure with gradual diameter and gradual tightening. The unique gradient depth filtration forms a three-dimensional filter residue effect, so that each layer of the multi-layer structure can intercept and store impurities in the water. 4 The raw polypropylene fibers of PP cotton with large flow and low pressure drop rely on self-adhesion to entangle each other to form a three-dimensional labyrinth microporous structure. Different from the fiber distribution in traditional fabrics and carded nonwovens, it has greater specific surface area, higher porosity. The large surface area and many small holes allow the water to pass through the PP cotton quickly, and the height of the inner and outer water will not be too different, so not only the filtration flow is large, but also the pressure difference is small. 5. Good chemical stability The chemical stability of PP cotton is closely related to its raw material polypropylene. The chemical stability of polypropylene is very good. In addition to being attacked by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to various other chemical preparations. Because of this performance, pp cotton is widely used in water purification and filtration of strong acids, alkalis and organic solvents. Therefore, in the future, when you replace the filter element of the water purifier, you should buy a high-quality PP filter element. Learn about PP filter elements:
