電子線グラフト重合法による製塩用次世代イオン交換膜の研究開発

抄録

We have been tackling research and development of next generation ion-exchange membranes for salt manufacturing process by electron–beam–induced graft polymerization from 2006 to 2010 on the research and development project of high–degree seawater concentration process for salt–manufacturing technology. First, an ultra high molecular weight polyethylene film was selected for a synthetic base film, and optimization of a synthetic method of ionexchange membranes was studied. Next, scale-up of the synthesis method of the ion–exchange membranes was studied, and pilot–scale synthetic equipments were constructed. Furthermore, the next generation ion–exchange membranes were produced by using the pilot–scale synthetic equipments. The produced ion–exchange membranes had high concentration performance, practical use and long-term stability.
