Dry-wet spinning of PSF hollow fiber membranes for the separation of N2-H2(Ⅰ)——effects of polymer solution and membrane thickness
【摘要】 采用干湿法纺丝工艺纺制了聚砜中空纤维 N2—H2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.
【Abstract】 The PSF hollow fiber membranes for the separation of nitrogen and hydrogen gases were manufactured by dry-wet spinning method.Effects of the polymer solution(its concentration,temperature,composition)and the membrane thickness on membrane perme- ation and separation properties were investigated.The structures of membranes were ob- served and analyzed by SEM and discussed by phase inversion theory.
