Description and composition characteristics of pp filters

PP filter based on polypropylene ( PP) Hot melt way, the micron number from 1 um to 300 um. Within the filter without inner shaft adopts the thin outside design, not only can maintain the stability of flow rate, pressure difference and service life, and has an excellent filtering effect depth and pollutant accumulation amount, is a kind of high efficiency, low pressure, long service life and applicability to a wide range of filter. Due to the chemical clean PP, and conform to the hygiene standards, not to have to filter liquid due to material to produce secondary pollution, has a large flow, high accuracy, corrosion resistance, high pressure, etc, are widely applied in PCB, plating, pure water, food and drinking water front filter processing, A prerequisite for the RO filter processing, etc.

PP filter is made from superfine polypropylene fiber thermal entanglement. Superfine fiber, relying on self bonding and tangles, in random space constitute a three-dimensional porous structure, fiber coupling between don't need any adhesives, especially has the characteristics of radial fiber a gradient variation, is a complex of many pass and fabric type filter medium. On one hand it can form deep filtering ( The characteristics of multi pass filtering material) , on the other hand, can form on the surface of filtering ( The characteristics of the fabric type filter material) , is the collection forecast 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 with high filtration efficiency, small pressure loss, stable filtration efficiency, long service life, the filter of low cost, good safety, strong adaptability.

melt-blown new filter different traditional fabric filter material, the material size is very fine, tend to be less than 5 - 25 micron, an irregular porous fiber mesh structure, average diameter less than 40 microns in diameter, the average porosity is greater than 75%, this structure for filtration precision control is very reliable.

PP filter internal fine fiber layer and outer layer of thick pine double fiber structure, effectively reduce the pressure loss, maintain the stability of the filtration efficiency. PP filter pore diameter gradient distribution along diameter direction, when filtering, part of the large aperture is large enough to hold the larger particles of impurities, to ensure that the filter is not quickly blocked, at the same time provide a good shape rigid; Aperture small part to stop the tiny particles, ensure that the filtering precision, so as to avoid the high precision filter clogging of the quick, short service life of disease, but also reduce the filtration resistance, reduce the energy consumption of the equipment, prolong the service life of filter element.

PP filters using the filter material is non-toxic, no smell of PP material, raw material sources and reliable security, no other chemical substances generated in the process of production, can be directly used for drinking water and beverage products, and because there was no any glue medium, the application material is dissolved. Mildew resistance, resistance to acid and alkali, inorganic and organic solvent ( Except chlorosulfonic acid, nitric acid and strong oxidizer) 。
