摘要
介绍了EDI膜堆填充材料的研究现状,认为离子交换树脂仍是今后填充材料的主要研究对象,离子交换纤维和其它新型填充材料的研究亟待有新的突破。同时,以树脂为例,对离子交换材料的3种填充方式(混合填充、分层填充、分置式填充)进行了系统介绍。最后对EDI膜堆填充材料及其填充方式的研究与发展作了展望。
The filling material in EDI stack is introduced in this paper. It is pointed out that the research on ion exchange resin filled in EDI stack is still the keystone in the future which is urgently needed for the new breakthrough on others new ion exchange materials and fiber for EDI stacks. Moreover, taking the ion exchange resin with filling materials for example, the three different filling forms i.e., mixed bed, layered bed and separate bed are reviewed. Finally, further research and development of the filling materials and filling forms is prospected.
