Function5结构

The main use of carboxymethylcellulose calcium is in tablet formulations, where it is used as a binder, diluent, and disintegrant.Although carboxymethylcellulose calcium is insoluble in water, it is an effective tablet disintegrant as it swells to several times its original bulk on contact with water. Concentrations up to 15% w/w may be used in tablet formulations; above this concentration, tablet hardness is reduced.

Carboxymethylcellulose calcium is also used in other applications similarly to carboxymethylcellulose sodium; for example, as a suspending or viscosity-increasing agent in oral and topical pharmaceutical formulations. Carboxymethylcellulose calcium is also used in modern wound dressings for its water absorption, retention and hemostatic properties.


Application
 
CMC-LV and CMC-HV can be directly used in all water base drilling fluids as filter loss reducer and viscosifier.

CMC-LV and CMC-HV are compatible with many water base drilling fluid additives. Recommended treatment is 0.3 - 1.5% in fresh water drilling fluids, and 0.7 - 0.9% in saltwater drilling fluids.
