Carboxy Methyl Cellulose (CMC)
SodiumCarboxymethyl Cellulose(CMC)
CAS: 9004-32-4
Carboxy Methyl Cellulose(CMC) kuj tseem hu ua SodiumCarboxymethyl Cellulose, yooj yim soluble hauv dej txias thiab dej kub. Sodium Carboxymethyl Cellulose (CMC) yog cov dej-soluble anionic cellulose ether uas tau los ntawm cov cellulose ntuj los ntawm kev hloov kho tshuaj. Nws muab cov khoom zoo ntawm thickening, water retention, film-forming, rheology thiab lubricity, uas ua rau CMC npog ntau yam kev siv xws li zaub mov, khoom siv tu tus kheej, xim pleev xim, ceramics, roj drilling, cov ntaub ntawv tsim kho thiab lwm yam. CMC yog synthesized los ntawm kev kho cellulose nrog sodium monochloroacetate hauv alkaline medium, ua rau carboxymethylation ntawm hydroxyl (-OH) pawg hauv cov saw cellulose.
