摘　　要：醋酸纤维素中空纤维初生膜由于膜孔径较大,结构疏松,因而必须经过一定的后处理才能获得较好的脱盐性能,而处理手段不同,其反渗透性能有很大不同,本文着重研究了表面活性剂、增塑荆、热处理时间、温度等对CA 中空反渗透膜脱盐性能的影响,从而找到获得最好脱盐性能的最佳后处理条件。The inital cellulose acetate hollow fiber reverse osmosis membrane hasa bigger pores and porous network structure,so it need heating-treatmentto obtain the better performance.In this paper,many factors during aftertreatment were investigated,such as the concentration of surfactant orplasticizers,duration and the temperture of thermal treatment on membraneperformance.
