Sodium Carboxymethyl Cellulose For Ceramic Billets
CMC can be used in ceramic body, glazing pulp, and fancy glaze. Used in ceramic body, it is a good strengthening agent, which can strengthen the mouldability of mud and sand materials, facilitate body shaping and increase the folding strength of the green body. Used in glazing pulp and fancy glaze, it is a binder that plays a role of suspending, deflocculating and water holding.
Application in ceramic decalcomania
CMC, with good solubility and high transparency of the solution, as well as no residue, possesses the excellent shear-thinning and lubrication, and greatly enhance the decalcomania adaptability and
*Good printing rheology to make printing fluency
*Clear pattern by printing and maintain the consistent color
*High smoothness, good lubrication, excellent effect
*Good water solubility, no residue, no sticking net, no blocking net
*high transparency of solution, and good net permeability
*Excellent thixotropy and lubrication, and greatly enhance the decalcomania adaptability.
The application of CMC in ceramic billets
1. It can increase the bonding strength of the billet and make the billet easy to form;
2. Improve the flexural strength of the billet and effectively reduce the damage rate of the billet;
3. Evenly evaporate the moisture in the billet to prevent dry explosion and cracking.
Application of CMC in Ceramic Tile Bottom Glaze and Top Glaze
1. Keep the glaze in a stable dispersed state;
2. Improve the surface tension of glaze;
3. Slow down the diffusion of water from the glaze to the billet;
4. Increase the smoothness of the glaze surface;
5. To avoid cracking and printing breakage during the conveying process caused by a decrease in the strength of the body after glaze application;
6. Reduce pinholes on the glazed surface after sintering.
