填充液压力对聚醚砜中空纤维膜微结构和性能的影响
Dependence of the Properties of PES Hollow Fiber on the Pressure of Internal Quench Medium
-
摘要: 研究了聚醚砜／二甲基亚砜(PEs／DMS0)体系中填充液压力的变化对PES中空纤维结构及性能的影响。结果表明，随着填充液压力的增大，中空纤维膜的水通量增大，轴向取向度下降。为纺制具有合适性能的中空纤维膜提供参考。Abstract: Dry-wet spinning technique was used for the preparation of PES hollow fiber membrane in this experiment. With increasing the pressure of internal quench medium, the water flux of PES hollow fiber membrane increases and the degree of orientation decreases.
