摘要

为解决混床内阳、阴树脂分离和混合效果的评价问题

提出了分离系数与混合系数的定义

介绍相关理论基础

给出计算方法。通过对国内外3家企业生产的混床用阳、阴树脂分离系数与混合系数的测定

提出了混床用树脂的评价指标和选择方法:根据粒径差选择均匀度好的阳、阴树脂;在允许混脂率和保证分离系数为正值的前提下

选择混合系数小的阳、阴树脂。

Abstract

In order to solve the problem for evaluating the separating effect and mixing effect of cation and anion resins in a mixed bed

the definisions of separation coefficient and mixing coefficient have been put forward

the related theoritical basis being presented

and the calculation method being given.Through measurement of the separation coefficient and the mixing coefficient for cation and aion resins used in a mixed bed and produced from three enterprises at home and abroad

the evaluation indices and selection method of resins used in the mixed bed have been given:selecting cation and anion lesins with good uniformity based on particle size difference;under prerequisite of having allowable mixing rate of resins and ensuring the separation coefficient to be positive value

cation and anion resins with little mixing coefficient have to be selected.
