Effect of cellulose ether etherification degree and temperature on water retention

A. The solubility and temperature of cellulose ether in water dependent on the degree of etherification.

B. As the temperature increases, the water retention decreases.

C. The higher the degree of etherification of cellulose ether, the better the high-temperature water retention of cellulose ether.

Usually, the temperature of fresh-mixed mortar is below 35 degree Celsius when in use. But under special climatic conditions, temperature can reach or even beyond 40 degree Celsius.

In this case, it is necessary to adjust the formula, considering not only other component but also the selection of appropriate cellulose ether.
