Ceramic Grade CMC

Description:

Sodium carboxymethyl cellulose (referred to CMC)  is  white  or yellowish powder,  granular  or fibrous  solid,tasteless,  non-toxic, and water  soluble. CMC  is  chosen  as  the  electrolyte  in  the production  of  sanitary  ceramics, due  to  its  good  adhesion, suspension, deagglomeration, and water retention effects.

Applications:

The application aim is to:

1). act as the binder and play a bonding role. It can increase the strength of raw glaze, reduce the drying shrinkage of glaze, make the green body and the glaze firmly combined and not easy to fall off, be easy for process operation, and prevent such defects as rolling and missing of glaze. While playing the role of suspension, it makes the ceramic slurry suspended and prevents precipitation.

2). play its role of water retention, so that the glaze slurry has a certain water retention and the glaze  layer  are  uniform  drying,  forming  a flat,  dense  glazed  surface  and  the  glazed surface  is  flat and smooth after firing.

3). use  the  deagglomeration  effects  of  CMC  (of  medium  and  low viscosity)  to  improve  the liquidity  of  glaze  slurry  and  facilitate  the  spraying  operation  of  glaze.  To  achieve  the  above purposes, it is very important to give full play to the effects of CMC, grasp the properties of CMC and the effects of temperature and time on it, and properly select and apply CMC.
