一、前言六十年代以来,离子交换膜电渗析技术已被大规模应用于浓缩海水制盐,咸水淡化制取淡水以及处理工业废水等方面。稍后,作为电极反应隔膜的应用也获得了推广,如:丙烯腈电解还原二聚制取尼龙66的原料已二腈,铀的电解还原以及电解食盐制取低含盐量的氢氧化钠等。作为电极反应隔膜用的离子交换膜和一般电渗析膜的要求不同,因为它要接触电极室的渗液,所以除一般要求外,还应具有耐酸、碱、化学腐蚀,耐温性好,抗氧化性好的特点。随着我国社会主义建设的发展,离子交换膜电渗析技术在国内已得到了广泛的应用,并对适于电解隔膜应用的离子交换膜提出了要求。为了寻找一种具有上述性能的离子交换膜,我们开
I. Introduction Since the 1960s, ion exchange membrane electrodialysis technology has been widely applied in the field of salt water concentration, desalination of fresh water and industrial wastewater treatment. Later, as the electrode reaction membrane applications have also been promoted, such as: acrylonitrile Electrolytic reduction dimerization of nylon 66 raw material has been two nitrile, electrolytic reduction of uranium and electrolysis of salt to make low-salt sodium hydroxide . As the electrode reaction membrane with ion exchange membrane and the general requirements of the electrodialysis membrane is different, because it is to contact the electrode compartment exudate, so in addition to the general requirements, but also with acid, alkali, chemical corrosion, temperature resistance, resistance Oxidation is good. With the development of socialist construction in our country, ion exchange membrane electrodialysis technology has been widely used in China, and the requirements of ion exchange membranes for electrolytic membrane applications are put forward. In order to find an ion exchange membrane with the above properties, we open
