| 摘 要： | 通过相转变法制备了一系列三醋酸纤维素/醋酸纤维素正渗透膜,并探索了影响正渗透膜水通量的三个重要因素:膜厚度、凝胶时间、热处理过程。结果表明膜厚度为300mm、凝胶时间48 h,并经过热处理以后的正渗透膜水通量效果最佳,达到7.088 L/m~2·h。

Performance Effects on Preparation Process of Cellulose Triacetate/Cellulose Acetate Forward Osmosis Membrane |
| |
| Abstract: | Series of osmosis membrane were prepared by phase inversion method with cellulose acetate and cellulose triacetate as membrane materials, and explored three important factors affecting water flux of forward osmosis membranes:The thickness of membrane, the gel time and the heat treatment process. The results show that the best technological conditions for preparing forward osmosis membrane is that the thickness is 300mm, gel time is 48 h and through heat treatment process. The water flux of forward osmosis prepared by these technological conditions reach 7.088 L/m2·h. |
