Superiority
| A. The Application Of CMC In The Ceramic Body |
| 1. It can stabilize physical and chemical property of glaze formulation. |
| 2. It can improve glaze adhesion and reduce glaze cracking. |
| 3.Make the moisture in the body evaporate uniformly to avoid dryness and cracking |
| B.The Application Of CMC In The Ground Coat And Cover Coat Of Ceramic Tile |
| 1. Make the glaze body in a state of stable dispersion |
| 2. Improve the surface tension of the glaze |
| 3. Slow water spreading from the glaze to the body |
| 4. Increase the smoothness of the glaze |
| 5.Avoid glazing cracking and printing fracture in the process of delivery caused by the decrease of body strength |
| 6 .Reduce the glaze pinhole after sintering |
| C. The Application Of CMC In The Printing Glaze (Or Stamp-Pad Ink, Ointment), Soluble Salt Glaze |
| 1. High water solubility, high transparency after dissolving, |
| 2. Not sticky, not plugging, effectively reduce the Frequency of wiping network |
| 3. Fine, good lubricity, high efficiency in passing network |
| 4. Good printing rheological property, make the printing more fluent, clear and consistent in color and luster |
| 5.Have a good compatibility with glazes, make the flower glaze steady, have a good performance of acid |
| resistance and alkali salt kang resistance. |
Details
1. Carboxymethyl cellulose (CMC) is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone.
2. It is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive.
3. The functional properties of CMC depend on the degree of substitution of the cellulose structure (i.e., how many of the hydroxyl groups have taken part in the substitution reaction), as well as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl substituents.
