Core Tip: Why always on pp cotton first stage of what it has in the end what advantages does pp cotton filter using non-toxic and tasteless polypropylene particles, through heating and melting, spinning, traction, receiving forming
?? Why in the first stage is always pp cotton? it does in the end has the advantage of what? pp cotton particle filter using a polypropylene non-toxic, odorless, after heating and melting, spinning, traction, receiving the tubular shaped filter made of . If the polypropylene-based feedstock, it can be called PP meltblown filter.
Currently, there is almost a first stage water filter cartridge are each pp cotton. Why always on pp cotton first stage of it? What is it in the end has the advantage of it?
pp cotton filter using non-toxic and tasteless polypropylene particles, through heating 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
Water flows from the inside to the outside pp cotton in water, filtered through layers , 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 a PP cotton filter different shapes and sizes. 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, in addition to be concentrated sulfuric acid, concentrated nitric acid corrosion, 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.
