Exploring the Applications and Benefits of Lotte HPMC in Modern Industry
Cellulose ether has a slow setting effect on mortar. With the increase of cellulose ether content, the setting time of mortar is prolonged. The retarding effect of cellulose ether on cement slurry mainly depends on the degree of substitution of alkyl group, which is not much related to its molecular weight. The lower the degree of alkyl substitution, the higher the hydroxyl content, the more obvious the retarding effect. And the higher the content of cellulose ether, the more obvious the retarding effect of the composite film on the early hydration of cement. Therefore, the more significant the retarding effect is.
