HC purification network now, according to the size of the filtering accuracy of the water purifier can be divided into four categories: microfiltration, ultrafiltration, nanofiltration and reverse osmosis. In these four types of water purification, almost a first stage of each filter is a water purifier pp cotton. Why always on pp cotton first stage of it?
Currently, the accuracy of the size of the filter press can be purifier into four categories: microfiltration, ultrafiltration, nanofiltration and reverse osmosis. In these four types of water purification, almost a first stage of each filter is a water purifier pp cotton. Why always on pp cotton first stage of it? It has in the end what advantage?
pp cotton filter using non-toxic and odorless polypropylene particles, after heating and melting, spinning, drawing, tubular shaped filter made of acceptance. If the polypropylene-based feedstock, it can be called PP meltblown filter.
Advantages PP cotton filter performance
1 can effectively remove a variety of particulate matter
pp water from the outside to the inside of the cotton flow of water through the layers of filtration , the inner layer closer to the filter, the filter pore size is smaller the higher the accuracy. After particulate impurities in the PP filter channels when, bridging phenomenon occurs even particles smaller than the pores, blocking can also be live, so that the filtered liquid to go addition of various particulate impurities.
2. The multilayer structure of a depth, a very large amount of pollutant
PP cotton filter outer relatively thick fibers, fine fibers and the inner layer, the outer layer is relatively loose, the inner then close, the graded composition gradual tightening diameter gradient multilayer structure. Each layer of such a multilayer structure can be intercepted, impurities in the water reservoir, together many layers, dirt holding capacity will be enormous.
3. The flow rate of filtration, pressure difference
PP raw cotton from polypropylene fibers bonded to each other to rely entangled three dimensional labyrinth microporous structure is formed, and with conventional textile carding different distribution of fibers in the nonwoven web, which has a larger specific surface, higher porosity. Large surface area and more holes, allowing water quickly through PP cotton, will not make too much difference between the height of the water inside and outside, so not only filter flow rate, and pressure is also smaller.
4. Free of chemical adhesives, more hygienic, safe
by the melt-blown polypropylene, traction, receiving technology, rely on the self-adhesive polypropylene fibers entangled with each other to form different shapes and sizes PP cotton filter. And other cartridges are not the same, PP cotton filter does not need to bond with other materials. Since the chemical composition of the PP clean, and in line with food hygiene standards, will not produce secondary pollution due to the material of the liquid to be filtered, safer to use.
5. Good chemical stability, acid, alkali, organic solvents, oils
PP cotton and chemical stability it is closely linked polypropylene material. Very good chemical stability of polypropylene, acid addition can be eroded, are relatively stable to a variety of other chemicals. Because of this property, pp quilts used in various fields of chemical, electronics and the like.
6. Collection surface, deep, coarse and fine filtration as a whole, has a large flow resistance, corrosion resistance, high pressure characteristics
Since the multiple advantages of PP cotton, having a large flow, high precision, corrosion resistance, and high pressure, coupled with its cost is not very high, pure water is widely used in food processing drinking water pre-filter, pre-filter processing machine RO penetration.
how we take the time to replace the cartridge?
In general, we can replace one time PP cotton filter through the first, to determine our home tap water is dirty or relatively normal, such as three months to replace PP cotton filter, the next time you will know later extended 2-3 months to replace does not matter, it can also prove water quality is relatively normal, the overall filter as the second, third, fifth grade filter 8-10 months or so to replace the big problem, an ultrafiltration membrane or fourth grade RO membrane 20 months or so does not matter.
Keep in mind that the interest of health, in time for the core is more important than the original buy water purifiers.
