双层阳离子交换器树脂选择

THE Choice of Resin in Double-deck Cation Exchanger

对含盐量较高的碱性水或碳酸盐性水进行离子交换除盐处理时，采用双层阳离子交换器是比较经济的。在对单层床进行双层床改造过程中，需要解决的主要问题有两个：一是强、弱酸树脂比例的确定；二是强、弱酸树脂的选型。为此应对强、弱酸树脂比例及型号加以确定。

Adopting the double-deck canon exchanger to take the salt in the basic water and the carbonate water involving more salt away is a more economical means. in the process of transforming one-course bed into doubledeck bed, there are two main problems to be solved. 1 .Define the resins ratio between strong acid and weak acid. 2. Define the resins type of strong acid and weak acid. There for,it is necessary to define the resins ratio between these two acids and the resins hoe of these two acids.
