Do you have water purifier product in your home ? why now many household use water purifier instead of using tap water. this is the study to know water purifier.At present, the first filter cartridges for almost every water purifier are pp cotton. Why is it always pp cotton in the first level? What kind of advantage does it have in the end?
The pp cotton filter adopts non-toxic and odorless polypropylene particles, and after being heated and melted, sprayed, hauled, and shaped to form a tubular filter element. If the raw material is polypropylene, it can be called PP solvent spray filter.
The advantages of PP cotton filter
- Can effectively remove various granular substances in water
The water flows from the outside of the pp cotton to the inside. After being filtered through layers, the closer the filter is to the inner layer of the filter, the smaller the hole diameter is, the higher the filtering accuracy is. Particle bridging occurs when passing through a PP filter cartridge channel. Even particles smaller than the channel can be blocked. This removes various particulate impurities from the filtered liquid.
- Multi-layer depth structure, very large amount of pollution
The outer layer of PP cotton filter has relatively thick fibers, while the inner layer has finer fibers, the outer layer is looser, and the inner layer is tighter, which constitutes a multi-layered gradient structure with progressively smaller diameters. Each layer of this multi-layer structure can intercept and store impurities in the water. When many layers are added together, the amount of pollutants will be large.
- Filter flow, small pressure difference
Polypropylene fibers of PP cotton rely on self-adhesion to entanglement with each other to form a three-dimensional labyrinth microporous structure, which is different from the fiber distribution in traditional fabrics and carded nonwovens, it has a larger specific surface area, higher Porosity. The large surface area and many small holes allow the water to pass through the PP cotton very quickly. The height of the inside and outside water will not be too different. Therefore, not only the filtration flow is large, but also the pressure difference is small.
- Non-chemical adhesive, more hygienic and safe
Polypropylene melt-blown, traction, receiving technology, so that polypropylene fibers rely on self-adhesion tangled each other to form different shapes and sizes of PP cotton filter. Unlike other filter elements, PP cotton filter elements do not require the use of other materials. Because the chemical composition of PP is clean, and meets the food hygiene standards, it will not cause secondary pollution of the liquid to be filtered due to the material, and it is safer to use.
- Good chemical stability, acid, alkali, organic solution, oil
The chemical stability of PP cotton is closely related to its raw material polypropylene. Polypropylene has good chemical stability, and it is stable to other chemical agents in addition to being eroded by concentrated sulfuric acid and concentrated nitric acid. Because of this property, pp cotton is used in various fields such as chemistry and electronics.
- Set surface, deep, coarse fine filter as a whole, with the characteristics of large flow, corrosion resistance, high pressure resistance
Due to the multiple advantages of PP cotton, it has the characteristics of large flow, high precision, corrosion resistance, high pressure, plus its cost is not very high, widely applicable to pure water, food pre-filtering treatment of drinking water, RO machine penetration Pre-filter processing.
