Each cellulose ether has the basic structure of cellulose-anhydroglucose structure. In the process of producing cellulose ether, the cellulose fiber is first heated in an alkaline solution, and then treated with an etherifying agent. The fibrous reaction product is purified and ground to form a uniform powder with a certain fineness.

Generally speaking, the higher the viscosity, the better the water retention effect of gypsum mortar. However, the higher the viscosity, the higher the molecular weight of the cellulose ether, and the corresponding reduction in its solubility, which has a negative impact on the strength and construction performance of the mortar. The higher the viscosity, the more obvious the thickening effect on the mortar, but it is not proportional.

In ready-mixed mortar, only a little bit of cellulose ether can significantly improve the performance of wet mortar. It can be seen that cellulose ether is a major additive that affects the construction performance of mortar.

Cellulose ethers are classified according to the different products of the etherifying agent used. Hydroxypropyl methyl cellulose, methyl cellulose, carboxymethyl cellulose, ethyl cellulose, hydroxyethyl cellulose, benzyl cyanoethyl cellulose Vegetarian, carboxymethyl hydroxyethyl cellulose, etc.
