PP filter is made of ultra-fine polypropylene fiber hot melt entanglement. Ultrafine fibers rely on their own bonding and entanglement, in space randomly constitute a three-dimensional microporous structure, fiber-to-fiber junction does not require any adhesive, in particular, has a radial fiber gradient characteristics, porous and fabric-based filter media Complex. On the one hand it can form a deep filter (porous filter material characteristics), on the other hand can also form a surface filter (fabric type filter material characteristics), is set pre-filter, fine filter and gravity settlement in one of the composite filter material, Has been widely used in drinking water purification, industrial water filtration and other fluid filtration.
PP melt spray new filter filter high efficiency, low pressure loss, filtration efficiency and stability, long life, low filtration cost, good security, strong adaptability. Melt blown new filter different traditional fabric filter material, this material is very fine wire diameter, often less than 5-25 microns, the fibers appear irregular porous network structure, the average diameter of less than 40 microns, the average porosity of more than 75%, so that The structure is very reliable for the control of the filter accuracy.
PP melt-blown new filter element using a non-toxic odorless PP material, the source of reliable and safe source of raw materials in the production process without other chemical substances can be directly used for drinking water and beverage products, and because no any bonding Medium, the application of non-soluble material appears. Resistant to mildew, acid and alkali resistance, organic or inorganic solvents (except chlorosulfonic acid, concentrated nitric acid and strong oxidants)
