Brief description and composition characteristics of PP filter element

PP filter is made of polypropylene (PP) hot melt method, its micron number from 1um to 300um. The filter element has no inner shaft and adopts the design of inner dense and outer sparse, which can not only maintain stable flow, pressure difference and service life, but also have excellent depth filtration effect and pollutant accumulation. It is a filter element with high efficiency, low pressure difference, long service life and wide applicability. Because the chemical composition of PP is clean, and in line with the food hygiene standards, will not be due to the material and the secondary pollution of the liquid to be filtered, has the characteristics of large flow, high precision, corrosion resistance, high pressure resistance, widely used in PCB, electroplating, pure water, food and drinking water pre-filtration treatment; RO pre-filter processing, etc.

PP filter element is made of ultra-fine polypropylene fiber hot melt tangles. Microfiber randomly forms three-dimensional microporous structure in space by its own bonding and tangling, and the interfiber connection does not need any adhesive. In particular, the radial fiber is characterized by gradient change, which is a complex of multi-pass and fabric type filter media. On one hand it can form deep filter (multi pass filtering material characteristics), on the other hand, can be formed on the surface of filtering the characteristics of the type of filtration material (fabric), is a concentration of pre filtration and fine filtration and gravity sedimentation in the integration of composite filter materials, has been widely used in drinking water purification, industrial pure water filter and other fluid.

PP filter element has high filtration efficiency, small pressure loss, stable filtration efficiency, long service life, low filtration cost, good safety and strong adaptability.

The melt-blown new filter element is different from the traditional fabric filter material. The filament diameter of this material is very fine, often less than 5-25 microns. The fiber presents an irregular porous network structure, with an average diameter of less than 40 microns and an average porosity of more than 75%.

PP filter inner fine fiber layer and external coarse fiber layer composed of double fiber structure, effectively reduce the pressure loss, to maintain a stable filtration efficiency. PP filter micropore diameter along the diameter of the gradient distribution, in the filtration, the large aperture can be enough to accommodate large particle impurities, to ensure that the filter will not be quickly blocked, while providing a good shape rigidity; The small aperture part can block fine particles, ensure the filtration accuracy, so as to avoid the disadvantages of high precision filter fast blockage, short life, but also reduce the filtering resistance, reduce the energy consumption of the equipment, prolong the service life of the filter element.

The filter material of PP filter element is non-toxic and odorless PP material, the source of raw material is reliable and safe, no other chemical substance is generated in the production process, can be directly used for drinking water and beverage products, and because there is no any adhesive medium, the application of insoluble material. Resistance to mildew, acid and alkali, organic or inorganic solvents (except chlorosulfonic acid, concentrated nitric acid and strong oxidants).
