The base support layer of the membrane is a porous material layer formed in a non-phase inversion manner. The material of the porous material layer is polypropylene or polyethylene.
The thickness of the membrane of this example is specifically 45 μm. The thickness of the membrane sheet of the present invention may be 50 μm or less, such as 45 μm in this embodiment, or 40 μm, 50 μm, 30 μm, 20 μm, 10 μm, 5 μm, etc., and the specific embodiment is determined according to the actual situation.
The substrate supporting layer of the membrane of the utility model is a porous material layer formed in a non-phase inversion mode. Wherein the material of the porous material layer is polypropylene or polyethylene. The material of the porous material layer in this embodiment is polypropylene.
The material of the porous material layer of the utility model can also be polyethylene. For a base support layer of polyethylene or polypropylene, which is a material of the porous material layer, the thickness of the membrane can be reduced, so that a thin membrane sheet with a thickness of 50um or less can be made, and the thickness of a conventional membrane is generally 150 um. Because the membrane is thin, the filter element with the same volume can roll more membranes, and because the membranes are more, the pollution resistance and the blockage resistance are good, and the cost of the porous material is low, the porous material can be replaced frequently.
