Mmetụta nke ogo nnọchi anya (DS) na Ogo HEC

HEC (hydroxyethyl cellulose) bụ polymer na-abụghị ionic, mmiri soluble nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche dị ka nlekọta onwe onye, ​​ọgwụ, na nri dị ka ihe na-eme ka ọ sie ike, na-ejikọta ya na onye na-eme ka ọ kwụsie ike. Ogo nke nnọchi (DS) bụ oke dị oke egwu nke nwere ike imetụta akụrụngwa na arụmọrụ nke HEC.

Ogo nke nnọchi na-ezo aka na nkezi ọnụ ọgụgụ nke otu hydroxyethyl nke jikọtara na nkeji anhydroglucose ọ bụla nke ọkpụkpụ azụ cellulose. N'ikwu ya n'ụzọ ọzọ, ọ na-atụ oke ókè ejirila otu hydroxyethyl gbanwee mkpụrụ ndụ cellulose.

Mmetụta nke ogo ngbanwe na àgwà HEC dị ịrịba ama. N'ozuzu, ka ogo nke nnọchi na-abawanye, solubility nke HEC na mmiri na-abawanye, na viscosity ya na-ebelata. HEC na ọkwa dị elu nke nnọchi nwere obere viscosity, ọ na-esikwa ike na mmiri. Nke a bụ n'ihi na otu hydroxyethyl na-akpaghasị njikọ nke hydrogen n'etiti ụdọ cellulose, na-eduga n'usoro mepere emepe ma na-agbanwe agbanwe.

Ọzọkwa, ọkwa dị elu nke ngbanwe nwere ike imeziwanye nkwụsi ike nke okpomọkụ nke HEC ma mee ka ọ ghara iguzogide mmebi enzymatic. Otú ọ dị, ngbanwe dị elu nke ukwuu nwere ike iduga mbelata nke ịdị arọ molekụla na nkwụsị nke ihe mbụ nke ọkpụkpụ azụ cellulose, nke nwere ike imetụta ọrụ zuru ezu nke HEC.

Na nchịkọta, ogo nke nnọchi bụ oke dị oke egwu nke nwere ike imetụta njirimara na arụmọrụ nke HEC. Ọkwa dị elu nke nnọchi nwere ike imeziwanye ihe solubility na nkwụsi ike nke HEC, mana oke ngbanwe nke ukwuu nwere ike iduga na-efunahụ ihe mbụ nke ọkpụkpụ azụ cellulose, nke nwere ike imetụta ọrụ zuru oke nke HEC.
