Most of the household water purifier or water purifier are used in the first level of the filter are PP filter, the first level of the filter will not only directly affect the water quality, will also affect the back of the three or four filtration effect and the life of the filter, so the quality of the PP filter for the water purifier is particularly important.
PP cartridge with polypropylene resin as raw material made of fibres, by the fibre itself winding bonded and become. The structure of the cartridge for the outer layer of fibre coarse, inner layer of fibre fine, the outer layer of loose, inner layer of tight gradient diameter gradient tight structure. From the outside to the inner layers of filtration, the closer to the inner layer of the cartridge, the smaller the pore size of the filtration precision is also higher.
As the particles will occur in the PP meltblown cartridge aperture bridging phenomenon, so that particles smaller than the aperture can also be blocked, can effectively remove all kinds of particles in the filtered liquid impurities.
This unique gradient deep filtration formed a three-dimensional filtration effect, can be multi-layer depth structure, large amount of dirt; PP meltblown cartridge Strength, when the filtration import and export pressure difference of 0.4Mpa, the filtration flow rate is large, the pressure difference is small, the filter element is not deformed; collection of the surface, the depth of the coarse and fine filtration as a whole; has a large flow rate, corrosion resistance, high pressure resistance, low-cost and other characteristics. It is used to block the rust, sediment, insect eggs and other large particles in the water.
There are many types of PP cotton filter on the market, we inevitably have some distress when choosing, then how to judge the quality of the cartridge good or bad as well as in the replacement of the problems that should be noted.
First, how to judge the quality of PP cotton filter good or bad
PP cotton cartridge quality is determined by the tightness of its fibres, high quality PP cotton cartridge internal fibres tight and uniform, and this difference in the purchase we can not see with the naked eye. A lot of filter material on the market is filter paper, good filter paper filtration performance is very good, those poor quality filter element using filter paper, can not prevent dust into the engine, will affect the normal operation of the machine.
First: look at the weight. We can use our hands to weigh the weight. The heavier the weight, the greater the fibre density of the filter element. The better the quality.
Second: look at the material. When choosing a cartridge, we must look at the material of the cartridge, the regular cartridge filter paper colour is uniform, the paper surface is flat. The poor quality filter cartridge filter paper colour is not uniform, the texture is poor.
Third: look at the compression. Usually the greater the fibre density of the cartridge. The better the compression performance, the better the quality of PP cotton cartridge. We can use the feel to judge, the stronger the feel, the better the compression performance.
Fourth: look at the gel. The rubber of the regular cartridge is very good, good elasticity, while the poor quality cartridge rubber is soft, poor texture.
Second, in the replacement of PP cotton filter need to pay attention to the problem
After a long time to replace the cartridge, when we want to replace the cartridge length is not enough when you can increase the rubber cushion method to solve. In the placement of the cartridge should also pay attention to put the cartridge correctly, in screwing the filter bottle if not screwed when not hard to unscrew the bottle to put the cartridge correctly, so as not to damage the cartridge. After the installation of the cartridge must be rinsed first, before access to the back of the system, general flushing time to ensure that more than 5 minutes. In fact, there is a problem is the cartridge in the end in what time to replace, there is no specific hard standard, the use of the cartridge time will depend on the water quality, generally 6-8 months, but it is best not to exceed 1 year!
After we choose a good PP cartridge, is our operation, the correct installation and replacement of the cartridge, to ensure that the normal work of the cartridge.
PP cotton cartridge aperture uniform and dense, the highest precision filtration up to 1μm, mainly used for tap water impurities greater than 1μm filtered out, in addition to the filtration process of the PP cotton filter is due to PP cotton filter belongs to the first level of the water purifier cartridge, more than 80% of the impurities will be filtered out in the level, and the more the filtered impurities, the more prone to clogging the cartridge. So the life of PP cotton filter is very short, poor water quality in the region may need to replace the cartridge more than two months, while the water quality of the region will not be more than six months at the longest. So if you buy a home water purifier inside the PP cotton filter, in order to avoid secondary pollution of the water purifier as well as the impact of the filter effect of the back of the cartridge, it is recommended that we replace the filter every 3-6 months or so.
