How to choose pp filter

PP filter element (also known as melt blown filter element) is a filter material made of non-toxic and odorless polypropylene as raw material, which is heated and melted, sprayed, drawn, and received. The pp filter element has a deep filtration structure with uniform pore size, sparse outside and dense inside, and has excellent characteristics of high filtration efficiency and acid and alkali resistance. Can effectively remove suspended solids, particles, rust and other impurities in the liquid.　　一, pp filter element 　　PP filter element is made of polypropylene (PP) by hot melt, and its micron number ranges from 1um to 300um. The filter element has no inner shaft and adopts inner density and outer sparse design, which not only can maintain stable flow, pressure difference and service life, but also has excellent deep filtration effect and pollutant accumulation. It is a kind of high efficiency, low pressure difference and long service life. And a filter element with a wide range of applicability. Because the chemical composition of PP is clean and meets food hygiene standards, it will not cause secondary pollution to the liquid to be filtered due to the material. It has the characteristics of large flow rate, high precision, corrosion resistance, and high pressure resistance. It is widely used in PCB and electroplating. , Pure water, food and drinking water pre-filtration treatment; RO permeation pre-filtration treatment, etc.　　Second, composition characteristics 　　PP filter element is made of ultra-fine polypropylene fiber thermally entangled. Ultra-fine fibers rely on self-bonding and entanglement to randomly form a three-dimensional microporous structure in space. The connection between fibers does not require any adhesive. It has the characteristic of gradient changes in radial fibers. It is a porous and fabric filter medium. Complex. On the one hand, it can form deep filtration (features of porous filter materials), on the other hand, it can form surface filtration (features of fabric filter materials). It is a composite filter material that integrates pre-filtration, fine filtration and gravity sedimentation. It has been widely used in the purification of drinking water, the filtration of industrial pure water and the filtration of other fluids.　　PP filter element has high filtration efficiency, low pressure loss, stable filtration efficiency, long service life, low filtration cost, good safety and strong adaptability. The new meltblown filter element is different from the traditional fabric filter material. The diameter of this material is very thin, often less than 5-25 microns. The fiber presents an irregular porous network structure. The average diameter is less than 40 microns, and the average porosity is greater than 75%. The structure is very reliable for the control of filtration accuracy.　　 The fine fiber layer inside the PP filter element and the loose fiber layer outside form a double-layer fiber structure, which effectively reduces pressure loss and maintains a stable filtration efficiency. The pore size of the PP filter element is distributed in a gradient along the diameter direction. During filtration, the larger pore size can accommodate larger particles and impurities to ensure that the filter element will not be clogged quickly, and at the same time provide good shape rigidity; small pore size part It can block fine particles and ensure the filtration accuracy, thus avoiding the shortcomings of fast clogging and short life of the high-precision filter element. It also reduces the filtration resistance, reduces the energy consumption of the equipment, and prolongs the service life of the filter element. The filter material of the PP filter element is made of non-toxic and odorless PP material. The raw material source is reliable and safe. No other chemical substances are generated during the production process. It can be directly used in drinking water and beverage products, and because there is no bonding medium, it is used No soluble material appears. It is resistant to mildew, acid and alkali, organic or inorganic solvents (except chlorosulfonic acid, concentrated nitric acid and strong oxidants). 3.
