The PP melt-blown filter core machine mainly uses the non-toxic and tasteless polypropylene particles, which is tubular filter through heating melting, spinneret, traction, acceptance forming. The raw material is mainly polypropylene, it can be called PP melt-blown filter core.
The PP melt-blown filter core machine is not only used in water purification in large quantities, but also has outstanding chemical compatibility. It is suitable for the filtration of strong acid, strong alkali and organic solvent. It has the high pollution capacity, long service life and low cost.
The PP melt-blown filter core machine has uniform pore density and more than 99 % filtration efficiency. The whole equipment has small filtration resistance and large filter flow, large pollutant holding quantity and long service life. In the process of production, the fiber diameter and clearance can be adjusted. The small inner layer of the filter core is small and outer layer is large, which increases the flow and pollutant holding quantity. The filter element is not easy to block and prolongs the service life.
The PP melt-blown filter core machine has very high cleanliness and no pollution to the water quality. The strength of the whole equipment is large. The filter element will not be deformed when the pressure difference of the inlet and outlet of the filter exceeds 0.4Mpa. When the temperature exceeds 90 ℃, the filtration efficiency will not decrease.
The structure of the PP melt-blown filter core machine is the gradual gradient structure whose outer layer fiber is thick and loose, and the inner layer fiber is thin and close. The unique gradient depth filtration formed the three-dimensional filter effect, with high porosity, high rejection rate, large pollutant holding quantity, large flow, low pressure drop.
