Ọdịdị 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:

(C6H10O5) n-CH2COOH

ebe n bụ ogo nnọchi anya (DS) nke otu carboxymethyl. Ogo nke nnọchi bụ ọnụọgụ nke otu carboxymethyl kwa molekul glucose. Ọganihu nke ngbanwe dị elu, ka viscosity nke ngwọta CMC dị elu.

Njirimara Carboxymethyl cellulose nwere ọtụtụ ihe pụrụ iche na-eme ka ọ baa uru na ngwa dị iche iche. Ọ bụ polymer soluble mmiri nke na-akwụsi ike nke ukwuu na ngwọta mmiri. Ọ bụkwa ihe na-adịghị egbu egbu, na-adịghị ewe iwe, na ọ dịghị ihe nfụkasị ahụ. CMC na-eguzogidekwa mmebi microbial na pH ma ọ bụ okpomọkụ adịghị emetụta ya. CMC bụ ihe na-emepụta ihe siri ike, enwere ike iji ya mee ka mmiri dị iche iche sie ike, gụnyere nri, ọgwụ na ihe ịchọ mma. A na-ejikwa ya dị ka emulsifier, stabilizer, na onye na-akwụsịtụ. A na-ejikwa CMC dị ka colloid nchebe na-emepụta akwụkwọ na textiles. Nchikota Carboxymethyl cellulose (CMC) bụ ụdị nke cellulose ewepụtara nke sitere na cellulose site 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 eriri ahịrị ahịrị nke molekul glucose jikọtara ọnụ site na njikọ glycosidic na carboxymethylated. Ọ nwere ọnụọgụ pụrụ iche nke na-eme ka ọ baa uru na ngwa dị iche iche. CMC bụ ihe na-eme ka ọ sie ike ma nwee ike iji ya dị ka emulsifier, stabilizer, na onye na-akwụsịtụ. A na-ejikwa ya dị ka colloid nchebe na-emepụta akwụkwọ na textiles.
