Why is the raw material of filter element PP ?
Aug 24, 2021
Most of the household water purifier or pure water machine first filter element is used are PP filter element, the first filter element will not only directly affect the water quality but also affect the back three or four filter effect and the life of the filter element, so the quality of PP filter element for water purifier is particularly important.
PP filter principle
PP filter element with polypropylene resin as raw material made of fiber, through the fiber itself wound bond. The structure of the filter element is a gradual diameter gradually tightening structure with coarse outer fiber, fine inner fiber, loose outer layer, and tight inner layer.
Filter from the outside to the inside layer, the closer to the inner layer of the filter element, the smaller the aperture of the filtration accuracy is also higher.
Because the particles in the PP melt-blown filter core in the bridge phenomenon, so that the particles smaller than the channel can also be blocked, can effectively remove all kinds of particle impurities in the filtered liquid.
This unique gradient deep filtration forms a three-dimensional filter slag effect, can be multi-layer depth structure, a large amount of pollution; PP melt-blown filter core strength, when the pressure difference between the inlet and outlet of the filter is 0.4mpa, the filtration flow is large, the pressure difference is small, the filter core is not deformed; 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.
Main functions of PP
PP has the characteristics of strong pollution capacity, long service life, low cost, does not contain any chemical adhesive, security guards, so it is used in large amounts in water purification, such as the use of groundwater/surface water initial filtration and pre-filtration of water purifier equipment. PP is mainly to remove coarse particles in water impurities, sludge, rust, suspended matter, etc.
