PP Cotton Functions And Characteristics
Aug 07, 2021
The chemical composition of the PP cotton filter element is in line with the food hygiene standards, and its adhesion without other adhesives, is the direct use of polypropylene melt-blown, traction, receive these technologies, so that polypropylene fiber relying on self-bonding and bonding each other. So PP cotton filter does not contain chemical adhesive, very safe and hygienic.
Its functions and features are as follows:
1. It can effectively remove and filter all kinds of particle impurities in the water
Raw water (tap water, groundwater, etc.) flows from the outside to the inside of PP cotton, after layers of filtration, the closer to the inner layer of the filter core, the smaller the aperture of the filtration accuracy is also higher. When the particle impurities pass through the PP filter core channel, the phenomenon of bridging will occur. Even the particles smaller than the channel can also be blocked to effectively remove all kinds of particle impurities in the filtered liquid.
2, multi-layer depth structure, A large amount of pollution
The outer fiber of the PP cotton filter core is coarse, and the inner fiber is fine, the outer layer is relatively loose, the inner layer is tight, and the multilayer gradient structure is formed. Each layer of this multilayer structure traps and stores impurities in the water, and the many layers add up to a large amount of contamination.
3. Large filtration flow and small pressure difference
PP cotton raw material polypropylene fiber relies on self-bonding to intertwine with each other, forming a three-dimensional curved microporous structure, and the distribution of fiber in the traditional fabric and carded net nonwovens is different, it has a larger specific surface area, higher porosity. A large surface area and more holes can let the water quickly through PP cotton, Which will not make the height of the water inside and outside too much different, so not only the filtration flow is large, but also the pressure difference is small.
4.set surface, deep, coarse fine filter as one; It has the characteristics of large flow, corrosion resistance, high-pressure resistance, and low cost. To block the water rust, sand, eggs, and other large particles.
