Ọdịdị nke sodium carboxymethyl cellulose

Okwu mmalite

Carboxymethyl cellulose (CMC) bụ ụdị mkpụrụ ndụ cellulose nke sitere na cellulose sitere na carboxymethylation.Ọ bụ ntụ na-acha ọcha, enweghị isi, ntụ ntụ na-enweghị ụtọ nke a na-ejikarị eme nri, ọgwụ, ihe ịchọ mma, na ụlọ ọrụ ndị ọzọ.CMC bụ polymer soluble mmiri nke nwere ọtụtụ ihe eji eme ihe n'ihi njirimara pụrụ iche ya.A na-eji ya dị ka ihe na-eme ka ọ dị arọ, ihe nkwụsi ike, emulsifier, na onye na-akwụsịtụ.A na-ejikwa CMC dị ka colloid nchebe na-emepụta akwụkwọ na textiles.

Ọdịdị nke carboxymethyl cellulose (CMC) bụ eriri ahịrị ahịrị nke molekul glucose jikọtara ọnụ site na njikọ glycosidic.A na-ejikọta ụmụ irighiri glucose na ibe ha site na otu atom oxygen, na-akpụ agbụ ahịrị.A na-emezi ụdọ linear carboxymethylated, nke pụtara na otu carboxymethyl (CH2COOH) jikọtara ya na otu hydroxyl (OH) nke molekul glucose.Usoro carboxymethylation a na-ebute molikula carboxymethyl cellulose ebubo na-adịghị mma.

Enwere ike ịnọchite anya usoro nke carboxymethyl cellulose site na usoro ndị a:
