Water purifier filter accessories - what are the advantages of PP cotton filter?

The filter element is the core component of the water purifier. The water purifier can produce high-quality water, and the filter element is the key. As the first-stage filter element of each water purifier, PP cotton plays a very important role in the water purifier and is an essential filter accessory. So what advantages does the PP cotton filter element have? 1. Purification of particulate impurities The effect 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. Even particles smaller than the pores can be blocked. More than 80% of the particulate impurities in the water will be filtered out at this stage. 2. 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 gradually increasing diameter and 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. 3 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 more 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. 4 Hygienic and safe Polypropylene is melt-blown, drawn, 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. 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 corroded 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. 6. Strong chemical compatibility and low cost Because of the multiple advantages of PP cotton, it has the characteristics of large flow, high precision, corrosion resistance and pressure resistance. In addition, its cost is not very high. It is widely used in pure water, food and drinking water. Pre-filtration treatment of RO water purifier, etc. Guangzhou fine-core filter element manufacturers talk about the relevant knowledge of the above PP filter elements based on the summary and experience of more than 10 years of Ru0026D and production, and hope to be helpful to you.
