Description of cmc chemical china
CMC Ceramic Grade can be used in the ceramic body as a reinforcer, excipient, and plasticizer. It can facilitate body shaping, CMC can also be used in glazing pulp and fancy glaze plays a role of thickening, binding, and dispersion.
It can raise surface tension of the glaze pulp.
It can stabilize the physical and chemical properties of glaze formulation.
As excipient of blank material to increase the mud plasticity, and make easy for body shaping.
Increase bending-resistant strength and smoothness of glaze.
High smoothness on glaze surface and stable glazing material, reduce the pinholes of the glaze surface after burning.
