Isakhiwo se-sodium carboxymethyl cellulose

Isingeniso

I-Carboxymethyl cellulose (CMC) iwuhlobo lokuphuma kwe-cellulose olutholakala ku-cellulose nge-carboxymethylation. Kuwumpushana omhlophe, ongenaphunga, onganambitheki osetshenziswa kakhulu ekudleni, emithini yemithi, kwezimonyo nakwezinye izimboni. I-CMC iyi-polymer encibilika emanzini enezinhlobonhlobo zokusetshenziswa ngenxa yezakhiwo zayo ezihlukile. Isetshenziswa njenge-ejenti yokuqina, i-stabilizer, i-emulsifier, ne-ejenti yokumisa. I-CMC iphinde isetshenziswe njenge-colloid evikelayo ekwenzeni iphepha nezindwangu.

Isakhiwo

Isakhiwo se-carboxymethyl cellulose (CMC) sakhiwe uchungechunge oluqondile lwama-molecule eglucose axhunywe ndawonye ngamabhondi e-glycosidic. Ama-molecule e-glucose axhunywe elinye nelinye nge-athomu eyodwa yomoya-mpilo, akha iketango eliwumugqa. Iketango eliwumugqa libe yi-carboxymethylated, okusho ukuthi iqembu le-carboxymethyl (CH2COOH) lixhunywe eqenjini le-hydroxyl (OH) le-molecule ye-glucose. Le nqubo ye-carboxymethylation iphumela ku-molecule ye-carboxymethyl cellulose ekhokhiswe kabi.

Isakhiwo se-carboxymethyl cellulose singamelelwa yifomula elandelayo:

(C6H10O5)n-CH2COOH

lapho u-n kuyizinga lokushintsha (DS) leqembu le-carboxymethyl. Izinga lokushintsha inani lamaqembu e-carboxymethyl nge-molecule ye-glucose. Uma izinga lokushintsha liphakeme, i-viscosity yesisombululo se-CMC iyanda.

Izakhiwo I-Carboxymethyl cellulose inenani lezinto ezihlukile eziyenza ibe wusizo ezinhlelweni ezihlukahlukene. Kuyi-polymer encibilika emanzini ezinzile kakhulu ezixazululweni ezinamanzi. Futhi ayinabo ubuthi, ayicunuli, futhi ayiyona i-allergenic. I-CMC futhi imelana nokuwohloka kwe-microbial futhi ayithinteki i-pH noma izinga lokushisa. I-CMC iyi-ejenti yokuqina enamandla futhi ingasetshenziselwa ukujiya uketshezi oluhlukahlukene, okuhlanganisa ukudla, imithi, nezimonyo. Ibuye isetshenziswe njenge-emulsifier, i-stabilizer, ne-ejenti yokumisa. I-CMC iphinde isetshenziswe njenge-colloid evikelayo ekwenzeni iphepha nezindwangu. Isiphetho I-Carboxymethyl cellulose (CMC) iwuhlobo lokuphuma kwe-cellulose olutholakala ku-cellulose nge-carboxymethylation. Kuwumpushana omhlophe, ongenaphunga, ongenambitheki futhi osetshenziswa kakhulu ekudleni, emithini yemithi, kwezimonyo nakwezinye izimboni. I-CMC yakhiwe iketango eliwumugqa lama-molecule eglucose axhunywe ndawonye ngamabhondi e-glycosidic kanye ne-carboxymethylated. Inenani lezinto eziyingqayizivele ezenza kube usizo ezinhlobonhlobo zezinhlelo zokusebenza. I-CMC iyi-ejenti yokuqina eqinile futhi ingasetshenziswa njenge-emulsifier, i-stabilizer, ne-ejenti elengayo. Ibuye isetshenziswe njenge-colloid evikelayo ekwenzeni iphepha nezindwangu.
