干湿法纺制聚砜中空纤维N_2—H_2分离膜(Ⅰ)——料液及膜厚的影响

Dry-wet spinning of PSF hollow fiber membranes for the separation of N_2-H_2(Ⅰ)——effects of polymer solution and membrane thickness

采用干湿法纺丝工艺纺制了聚砜中空纤维 N_2—H_2分离膜,研究了料液的浓度、温度、组成及中空纤维壁厚对膜性能的影响,用电镜照片观察和分析了膜的结构并结合相转化原理进行了讨论.

Effects of coagulation conditions on the membrane permeation properties and membrane structures were studied, especially that of bore liquid. The structures of membranes were observed by SEM and discussed by phase inversion theory and solubility parameter theory.
