Description:
In ceramic industry, carboxymethyl cellulose ceramic grade is used as the ceramic blank adhesive, plasticizer, glaze suspending agent, color fixing agent and etc. Adding carboxymethyl cellulose into blanks will enhance the blank adhesiveness (no residues and easily forming), improve mechanical strength and reduce the blank breaking rate. After adding carboxymethyl cellulose into the glaze, it will enhance the bonding of blanks and glaze, promote the glaze dispersing, and also enhance the adhesion strength of the glaze and ceramics.
As the flow control agent in ceramic glaze, carboxymethyl cellulose can prevent the glaze from falling off into tear stains before burning finished, and the high-purity CMC leaves no ash in the process of burning.

Applications:
The application aim is to:
1). Carboxymethyl cellulose 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.
