CMC can add in ceramic body or glaze,
CMC has the following excellent performance in the ceramic body:
- It can strengthen the bond of the body,and increase the plasticity of sediment material,easier molding;
- Improve the flexural strength,improve body stability,and it is more suitable for machining ceramic products processing;
- Improve the body production speed,reduce processing cost,and can make the water in body material evenly evaporation, prevent the dry cracking,improve the top-grade product rate.
CMC has the following excellent performance in the ceramic glaze:
- Improve the surface tension of glaze;
- Make the compostion of glaze evenly dispersed;
- Increase the bending strength of body and the surface smoothness;
- Avoid body spalling and bubble after glazing because of body strength changed,reduced pinhole after drying, and produce the smooth glaze.
