CMC in Ceramic Industry
1.CMC for ceramics features uniform distribution of substituents (carboxymethyl group) on the cellulose backbone. It produces fewer gel granules in glaze formulation.
2. It contains no colored impurity and is 100% combustible under firing condition, to ensure clean ceramic glaze.
3. It can stabilize physical and chemical property of glaze formulation.
4. It can improve glaze adhesion and reduce glaze cracking.
5. It facilitates formation of a smooth dense glaze layer.
6. It can improve the rheological property of glaze formulation.
7. The glaze viscosity is proportional to the concentration of CMC added
