| titleOfInvention | Polymer ultrafiltration membrane applied to polyamide composite membrane support and preparation method thereof |
| abstract | The invention provides a polymer ultrafiltration membrane applied to support of a polyamide composite membrane, which has a two-layer structure, wherein the two-layer structure comprises a small pore structure layer close to a polyamide separation layer and a large pore structure layer adjacent to the small pore structure layer, the pore diameter of the small pore structure layer is about 5-20nm, the pore diameter of the large pore structure layer is about 50-500nm, and a dealuminized aluminosilicate molecular sieve is doped in the small pore structure layer. The invention improves the ultrafiltration support body, and ensures the spreading of the water phase monomer on the surface of the membrane on the basis of ensuring the water flux. |
