What does the simplest PP cotton hide that you don't know?

PP cotton cartridge, also known as meltblown PP cartridge, the use of non-toxic and odorless polypropylene particles, through the heating of molten, spraying, traction, acceptance of molding made of tubular cartridges; if the raw material to polypropylene-based, it can be called PP meltblown cartridge.

PP cotton cartridge features
1, the filtration precision of this cartridge is very high, after a relatively strict production technology, so that the quality of the product is extremely stable and reliable. Its filtration capacity is also larger than other cartridges, and the pressure loss is small.
2, the service life of this kind of cartridge is long, and its cost is not very high. It is mainly in the structure, completely tight inside and outside the loose structure characteristics, to ensure that the dirt holding capacity, so that the life has been extended.
 3、Absolute corrosion resistance, a wide range of applications. Because this kind of cartridge is only composed of one kind of material, so it is absolutely stable in nature, which makes it corrosive.

PP cotton cartridge application areas
PP cotton cartridge has a wide range of applications, in pure water, solvents, pharmaceutical industry, electronics industry, petrochemical industry, food and beverage industry, liquid filtration and compressed gas can be filtered.
For example, in the pharmaceutical industry, some of the injection, liquid and injection bottle washing water pre-filtration, I.V. and a variety of antimicrobial agents, Chinese medicine injection pre-filtration. In the food industry, there are filtration of alcohol, beverage and drinking water. Petroleum and chemical industry, filtration of all kinds of organic solvents, acids and alkalis, and filtration of oilfield water injection. Electronic industry, pre-filtration of pure water and ultra-pure water.

PP cotton filter element quality identification
The quality of PP cotton cartridge is determined by the tightness of its fibers, high quality PP cotton cartridge internal fibers are tight and uniform. And this difference in the purchase we can not use the naked eye can be seen. Then how should we recognize it?
First: look at the weight. We can use our hands to weigh the weight. The heavier the weight, the fiber density of the cartridge is greater. The better the quality.
Second: look at the compression. Usually the greater the fiber 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.
Second: look at the material. When choosing a cartridge must look at the material of the cartridge, the regular cartridge filter paper color unity, paper surface flat. The poor quality cartridge filter paper color is not uniform, poor texture.
Fourth: look at the gel. Regular cartridge rubber is very good, good elasticity, while the poor quality cartridge rubber is soft, poor texture.
These two points we may not be able to use in the purchase of a new water purifier, but we can come in handy when we buy a separate PP cotton filter replacement.

PP cotton cartridge life
1, precision
1 micron (um), 10 micron (um), 20 micron (um), 50 micron (um)
The higher the precision the shorter the service life, but the filter medium is more thorough, due to the turbidity of the filter medium (fine particles, etc.), so the cartridge is more prone to dirt gambling, once the cartridge dirt gambling, it will affect its service life.

2, water media
Pure water: after reverse osmosis or ultrafiltration filtration of pure water and then filtered with PP cotton cartridge, the use of this water cartridge should be relatively long, because the water itself is very clean, PP cotton cartridge cycle is generally 6 months.
Tap water: water company treated groundwater or river water, called tap water, generally used for pure water production. Now the domestic use of pure water production industry, common mainly to reverse osmosis RO water purifier, after the sand carbon filter, reverse osmosis into the water before the use of filters, containing PP cotton core, general accuracy of 10 microns, used to filter sand carbon filter can not be filtered out of fine turbid particles, according to the effect of the sand carbon filter, the differences in the source of tap water around the world, the use of PP cotton filter cycle of 15 days -2 months.
Ultra-pure water: ultra-pure water is after reverse osmosis, ultra-pure water resin or EDI after the end of the filtration, its water quality to achieve absolute purity, so the use of a longer cycle, the use of PP cotton cartridge cycle of 6-12 months replacement.
Drinking water for domestic use: small water purifier, used in front of the water purifier, its service life is 1-2 months.
 Water reuse: also known as water reuse, is the industrial discharge of sewage, in accordance with national emission standards for treatment, and then further processing to achieve recycling. Which the first section of water filtered with PP cotton cartridge, the relative turbidity particulate matter is more, more large, so the service life will be shortened, PP cotton cartridge use cycle for 7 days -30 days.
