摘要
本文以聚矾和磺化聚砜共混物为膜材料,二甲基乙酰胺为溶剂,聚乙烯吡咯啉酮和邻苯二甲酸二甲酯为添加剂配制纺丝液,纺制外压中空纤维超滤膜。该膜对2万分子量的聚乙二醇溶液的截留率≥94%,纯水透过率为12—18 l/h·m^2。探讨了制膜液组成,不同填加剂及用量等参数对膜性能的影响。
This paper reported the preparation of hollow fiber UF membrane,using PS and SPS as membrane spinning materials,DMA as solvent,PVPand dimethyl phthalate as additives.Its rejection rate of PEG(M_N=20000)is≥94%,pure water fluxes 12-18 L/(h·m^2).The influence of many parameters on the membrane properties,forexample,the composition of spinning solution,the kind of additives,thecontent of additives etc,was also described in this paper.
