In industrial production, it is sometimes possible to judge the time for resin regeneration by observing the color change of the resin used. Therefore, people continue to use ion exchange resins with indicators, which not only have a distinct function of discoloration, but also have better exchange ability than ordinary resins. Suzhou Bojie Resin Technology Co., Ltd. provides color-changing mixed-bed resin, which has obvious color change and can effectively display the working state of the resin exchange column. The color difference between regenerative and failure is very obvious.
