Sodium carboxymethyl cellulose

Sodium carboxymethyl cellulose (CMC-Na) ke motsoako oa carboxymethylated oa selulose 'me ke ionic cellulose gum ea bohlokoa ka ho fetisisa. Sodium carboxymethyl cellulose hangata ke motsoako oa anionic polymer o lokiselitsoeng ka ho arabela cellulose ea tlhaho ka caustic alkali le monochloroacetic acid, e nang le boima ba molek'hule ho tloha ho likete tse 'maloa ho isa ho limilione. CMC-Na ke phofo e tšoeu ea fibrous kapa granular, ha e na monko, ha e na tatso, e hygroscopic, e hasanngoa habonolo metsing ho etsa tharollo ea colloidal e hlakileng.
