PP melt blown filter element is mainly made of polypropylene, which is a filter material made by heating and melting. The filtration of PP melt blown filter element is mainly divided into two types: deep filtration and surface filtration.

The filtration of PP melt blown filter element is a composite filter material integrating 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 melt blown filter element is made of ultra-fine polypropylene fiber hot melt entanglement.

Superfine fibers rely on their own adhesion and entanglement to randomly form a three-dimensional microporous structure in space. The connection between fibers does not need any adhesive. In particular, it has the characteristics of gradient change of radial fibers. It is a complex of porous and fabric filter media.

PP melt blown filter element has a deep filtration structure with uniform pore size, sparse outside and dense inside, and has the excellent characteristics of high filtration efficiency and acid and alkali resistance. It can effectively remove suspended solids, particles, rust and other impurities in the liquid.

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

The PP melt blown filter element is different from the traditional fabric filter material. The wire diameter of this material is very fine, often less than 5-25 microns, and the fiber presents an irregular porous network structure. The average diameter is less than 40 microns, and the average porosity is greater than 75%. This structure is very reliable for the control of filtration accuracy.

The fine fiber layer inside the PP melt blown filter element and the coarse fiber layer outside form a double-layer fiber structure, which effectively reduces the pressure loss and maintains a stable filtration efficiency.

The micropore diameter of PP melt blown filter element is distributed in gradient along the diameter direction. During filtration, the part with large diameter can accommodate large particle impurities to ensure that the filter element will not be blocked quickly;

The part with small pore diameter can block fine particles and ensure the filtration accuracy, so as to avoid the disadvantages of fast blockage and short service life of the high-precision filter element, reduce the filtration resistance, reduce the energy consumption of the equipment and prolong the service life of the filter element.

The filter material of PP melt blown filter element is non-toxic and odorless PP material. The source of raw materials is reliable and safe. No other chemical substances are generated in the production process. It can be directly used in drinking water and beverage products. Because there is no adhesive medium, there is no soluble material in application.
