Composite material industry more filter filtering effect

Gradient filter element has the center frame and the filter layer, the filter layer is composed of two or more gradient filter layer, the filter aperture gradually decrease from outside to inside, the gradient filter element can make full use of each filter layer to achieve better filtering effect, set in the center of the frame can support and resistance to industrial water high pressure filter layer, small make up today will go to the industrial filter filtering effect of compound material. Composite material industry filter including more from the outside to the external, in turn, decorate the outside of the filter layer, middle filter layer, the internal filter layer and skeleton, skeleton layer made of permeable materials, the filter layer made of polypropylene, middle filter layer is made from activated carbon, the filter layer is made from polyether sulfone, outside the filtering precision of the filter layer of 50 microns - 200 microns, the filter layer in the middle of the filter precision accuracy of 1 mu m - 50 microns, internal filter layer filtration precision of 0. 01μm- 1μm。 Skeleton layer made of polypropylene, the outside the filtering precision of filter layer is 200 microns, the filter layer in the middle of the filtration precision is 30 microns, internal filter layer filtration precision of 0. 08 microns, outer layer of filter filtration accuracy is 150 microns, the filter layer in the middle of the filtering precision of 10 microns, internal filter layer filtration precision of 0. 05μm。 Filter external filter layer, middle layer and internal filtration layer as a plug-in way together, external filter layer thickness is 3 cm, the thickness of the filter layer is 3 cm, middle internal filter layer thickness of 2 cm, and the framework layer thickness of 2 cm.
