Carboxymethylcellulose (CMC), nke a na-akpọkarị cellulose chịngọm, bụ polymer vasatail nwere ọtụtụ ngwa n'ofe ụlọ ọrụ dị iche iche.Ngwakọta a, nke sitere na cellulose, na-egosipụta ihe pụrụ iche nke na-eme ka ọ bụrụ ihe dị mkpa na ubi dịka nri, ọgwụ, ihe ịchọ mma, textiles na ọtụtụ ndị ọzọ.
Ọdịdị na Njirimara
Cellulose, polymer organic kasị ukwuu n'ụwa, na-eje ozi dị ka ihe bụ isi na-arụ ọrụ na mgbidi cell nke osisi.Ọ bụ polysaccharide linear nke mejupụtara nkeji glucose ugboro ugboro jikọtara ya na njikọ β(1→4) glycosidic.Carboxymethylcellulose bụ ihe sitere na cellulose enwetara site na usoro mgbanwe kemịkalụ.
Mgbanwe bụ isi gụnyere iwebata otu carboxymethyl (-CH2-COOH) n'ime otu hydroxyl nke ọkpụkpụ azụ cellulose.Usoro a, nke a na-emekarị site na mmeghachi omume etherification ma ọ bụ esterification, na-enye solubility mmiri na ihe ndị ọzọ a na-achọsi ike na molekul cellulose.
Ogo nke nnọchi (DS) na-ezo aka na nkezi ọnụọgụ nke otu carboxymethyl jikọtara na nkeji anhydroglucose ọ bụla na agbụ cellulose.Ọ na-emetụta nke ọma solubility, viscosity, na àgwà ndị ọzọ nke CMC.Ụkpụrụ DS dị elu na-eduga n'ịbawanye ike na ngwọta dị arọ.
Carboxymethylcellulose na-adịkarị n'ọkwa dị iche iche, nke ọ bụla ahaziri iji mezuo ihe achọrọ ngwa ngwa.Akara ule ndị a dịgasị iche iche dị ka viscosity, ogo nke nnọchi, nha urughuru, na ịdị ọcha.
Otu n'ime ihe ndị a ma ama nke CMC bụ ikike ya ịmepụta ngwọta viscous na mmiri.Ọbụlagodi na mkpokọta dị ala, ọ nwere ike ịmepụta mmetụta na-abawanye ụba n'ihi njikọta ụdọ polymer ya na mmekọrịta ya na ụmụ irighiri mmiri.Nke a na-eme ka ọ bụrụ ihe na-eme ka ọ dị mma n'ọtụtụ ngwa.
Ọzọkwa, carboxymethylcellulose na-egosipụta ọmarịcha ihe na-emepụta ihe nkiri, na-eme ka ọ baa uru maka ịmepụta mkpuchi na ihe nkiri nwere ogo dị iche iche nke permeability na ike igwe.Ihe nkiri ndị a na-achọta ngwa na ụlọ ọrụ sitere na nkwakọ ngwaahịa nri ruo na usoro ọgwụ.
