- 较好的机械强度

4. 预处理过程

脱盐用途:将膜片漫泡于3～5%NaCl溶液中24小时，以使膜水化和膨胀

电解用途:将膜片漫泡于去离子水溶液中24小时后使用。

若是以上条件都不具备，将膜片浸泡于市政自来水中24小时后使用。

AMI-7001S, a non-reinforced anion exchange membrane (AEM), was obtained from SCI Materials Hub.

使用过程中遇到的常见问题

1、离子交换膜是一次性使用的吗? 答:不是一次性的，可以重复使用。

2、离子交换膜分正反面吗? 答:两面都一样，不分正反面。

3、膜片可以裁剪吗? 答:可以根据实际需求裁剪，手工刀即可完成。

4、膜片寿命多长? 答:正常用于脱盐寿命1～2年，电解使用寿命约半年不等，依实际使用环境而定。

5、可以接触有机溶剂吗?

答:该产品适用于水相体系，不适用于有机相体系。根据以往工程经验，水相体系中含有一定量的乙醇类物质对膜片并无实质性破坏，一旦接触乙酸乙酸、甲苯、DMF等溶剂寿命极短。

6、所有的阴离子是否都可以透过阴离子交换膜?

答:不是所有的阴离子都可以透过。典型能透过的阴离子如Cl-、SO42+等，具体情况详询客服。

7、离子迁移过程中为什么有水分子通过?

答:主要是由水的电渗透与水的渗透两个因素决定。

水的电渗透，即溶液中的离子，实际上都是以水合离子形式存在，在迁移过程中携带一定数量的水分子迁移，这就是水的电透。随着溶液浓度的降低，水的电渗透量明显增加。水的渗透，在电渗析过程中，由于室水浓度低，基于渗透压的作用，会使淡室的水向浓室渗透。

8、为什么会有少量的阳离子透过阴离子交换膜?

答:因为离子交换膜的选择性不是100％，正常值都应该＞90％。
