摘要
根据Stocks模型 ,对混床用阳阴树脂沉降速度、沉降比进行计算和分析。结果表明 ,符合标准的阳、阴树脂沉降速度、沉降比有很大差别 ,粒度、密度不同 ,分离效果就不同 ,选择和评价混床树脂时 ,应对阳、阴树脂粒度分布、沉降速度、沉降比进行综合考察 。
Based on Stokes Law,settling velocity and ratio of settling velocity of cation and anion exchange resin in mixed bed are calculated and analyzed. It shows that the settling velocity and the ratio of settling velocity differ greatly and this results in different resin separation effect if cation and anion exchange resin according with the standard is different in particle size and density. In order to determine its separation effect,the distribution of particle size settling velocity as well as ratio of settling velocity of cation and anion exchange resin should be considered comprehensively in choosing and evaluating the exchange resin in mixed bed.
