以纤维素浆板和二醋酸纤维素为原料 ,通过直接制膜和醋酸纤维素成膜后水解两种方法制备再生纤维素超滤膜 ,并以酱油、药酒和牛奶等为料液 ,对膜进行了耐污染实验 .与聚砜和聚丙烯腈膜比较 ,再生纤维素膜具有良好的耐污染特性 . Using cellulose pulp and cellulose diacetate as raw materials, regenerated cellulose ultrafiltration membrane was prepared by direct membrane formation and hydrolysis after cellulose acetate membrane formation. Using soy sauce, wine and milk as feed solution, Pollution resistance experiments were carried out.Compared with polysulfone and polyacrylonitrile membranes, the regenerated cellulose membranes had good anti-pollution properties.
