The preparation technology and pore-forming mechanism of the three methods were introduced respec- tively, and the history and development of them are reviewed and discussed. The trends of preparation methods for hollow fiber membrane are also indicated. Key words: solution spinning method; melt-spinning-cold stretching method; thermally induced phase separa- tion method; hollow fiber membrane; preparation methods; development 前 言 究进展进行介绍。 随着我国经济社会的发展,传统的水净化工 1 溶液纺丝法 艺如氯化、絮凝沉淀、离子交换等处理方法已不 能满足低投资、低运行成本、高水质和稳定可靠 1.1 致孔机理 的要求,新技术、新产品的开发显得尤为重要。
