    摘要: PROBLEM TO BE SOLVED: To provide a vinylidene fluoride family resin porosity water treatment membrane (a) little in membrane contamination during filtration (high flux retention rate), (b) maintaining its low stain resistance after repeated washing with a chemical (high tolerance to chemical-washing); and (c) having a favorable mechanical strength. SOLUTION: A low stain resistance porosity water treatment membrane is a porous membrane made of a vinylidene fluoride-based resin wherein the outer surface is selectively hydrophilized. Preferably, the low stain resistance porosity water treatment membrane includes a porosity membrane having a hollow fiber shape. COPYRIGHT: (C)2008,JPO&INPIT
