CMC FC1200

CMC FC1200

KimaCell® CMC FC1200 sodium carboxymethyl cellulose. The ceramic industry is commonly known as "methyl", which is an anionic substance and is a white or slightly yellow powder made from natural cellulose through chemical modification. CMC has good solubility and can be dissolved into a transparent and uniformly viscous solution in both cold water and hot water. Density 0.5-0.7 g/cm3, almost odorless, tasteless, hygroscopic. Easily dispersed in water to form a transparent colloidal solution, insoluble in organic solvents such as ethanol. CMC is used in ceramics as retarder, water retention agent, thickener and stabilizer. In the ceramic production process, it is used in the ceramic body, glaze slurry and printing to significantly improve the flexural strength of the body and improve the stability of the glaze slurry.

Application of CMC FC1200

KimaCell® CMC FC1200 sodium carboxymethyl cellulose is has a unique linear polymer structure. When CMC is added to water, its hydrophilic group (-COONa) combines with water to form a solvation layer, so that CMC molecules gradually disperse in water, thus showing cohesiveness. The body-specific CMC can be used as an excipient, plasticizer, and reinforcing agent for green bodies in the ceramic industry. Adding an appropriate amount of CMC to the billet can increase the cohesive force of the billet, make the billet easy to form, increase the flexural strength by 2 to 3 times, and improve the stability of the billet, thereby increasing the high-quality product rate of ceramics and reducing post-processing costs. . At the same time, due to the addition of CMC, it can increase the green body processing speed and reduce production energy consumption. It can also make the moisture in the billet evaporate evenly and prevent drying and cracking. Especially when it is applied to large-sized floor tile billets and polished brick billets, the effect is even better. obvious. Compared with other green body reinforcing agents, green body special CMC has the following characteristics: less dosage: the addition amount is generally less than 0.1%, which is 1/5 to 1/3 of other green body strengthening agents, while green body The increase in flexural strength is obvious, and the cost can be reduced at the same time. Good inflammability: almost no ash is left after burning, and there is no residue, which does not affect the color of the blank. It has very good suspending ability: prevent the barren raw material and color paste from settling, and make the paste disperse evenly. Anti-abrasion: In the process of ball milling, the molecular chain is less damaged.
