Water retention of cellulose ether

The water retention of mortar refers to the ability of mortar to maintain and lock moisture. The higher the viscosity of cellulose ether, the better the water retention.

Since the cellulose ether structure contains both the hydroxide and the ether bond, the oxygen atoms on the OH and ether bond groups form hydrogen bonds with the water molecules, making the free water into bound water and winding the water, thus acting as water retention.

The finer the particles of cellulose ether, the better the water retention, and the surface of coarse cellulose ether immediately dissolved and formed a gel phenomenon after contact with water. The glue wraps the material to prevent the water molecules from continuing to penetrate.

Sometimes it is not evenly dispersed and dissolved after a long period of stirring, forming a turbid and fluffy solution or agglomeration. Fine particles are dispersed and dissolved immediately after contact with water to form a uniform viscosity.
