Uyini umehluko phakathi kwe-HEC ne-CMC?

I-HEC ne-CMC yizinhlobo ezimbili ze-cellulose ether, i-polysaccharide etholakala ezitshalweni futhi isetshenziswa emikhiqizweni eyahlukene. Ngenkathi zombili zitholakala ku-cellulose, zinezakhiwo ezihlukile kanye nezicelo.

I-HEC, noma i-hydroxyethyl cellulose, iyi-polymer engeyona i-ionic, encibilika emanzini etholakala ku-cellulose. Isetshenziswa njenge-ejenti yokuqina, i-emulsifier, i-stabilizer, kanye ne-ejenti emisa okwesikhashana emikhiqizweni eyahlukene, okuhlanganisa izimonyo, imithi, nemikhiqizo yokudla. I-HEC iphinde isetshenziselwe ukukhulisa i-viscosity yezixazululo ezinamanzi kanye nokwenza ngcono ukuthungwa kwemikhiqizo. Ibuye isetshenziselwe ukwenza iphepha, upende nezinto ezinamathelayo.

I-CMC, noma i-carboxymethyl cellulose, i-polymer encibilika emanzini etholakala ku-cellulose. Isetshenziswa njenge-ejenti yokuqina, i-emulsifier, i-stabilizer, kanye ne-ejenti emisa okwesikhashana emikhiqizweni eyahlukene, okuhlanganisa izimonyo, imithi, nemikhiqizo yokudla. I-CMC iphinde isetshenziselwe ukukhulisa i-viscosity yezixazululo ezinamanzi kanye nokwenza ngcono ukuthungwa kwemikhiqizo. Ibuye isetshenziselwe ukwenza iphepha, upende nezinto ezinamathelayo.

Umehluko omkhulu phakathi kwe-HEC ne-CMC usesakhiwo sazo samakhemikhali. I-HEC iyi-polymer engeyona i-ionic, okusho ukuthi ayinawo amashaji ahlotshaniswa nayo. I-CMC, ngakolunye uhlangothi, i-polymer ye-ionic, okusho ukuthi ineshaji elibi elihlotshaniswa nayo. Lo mehluko ekuphathweni uthinta indlela ama-polymers amabili asebenzisana ngayo namanye ama-molecule, futhi ngaleyo ndlela athinte izakhiwo zawo nokusebenza kwawo.

I-HEC incibilika kakhulu emanzini kune-CMC, futhi isebenza kangcono njenge-ejenti ejiya. Iphinde izinze kakhulu ezixazululweni ezine-asidi ne-alkaline, futhi imelana kakhulu nokushisa nokukhanya. I-HEC futhi imelana kakhulu nokuwohloka kwamagciwane, okwenza kube ukukhetha okungcono emikhiqizweni edinga isikhathi eside seshelufu.

I-CMC ayincibiliki kancane emanzini kune-HEC, futhi ayisebenzi kahle njenge-ejenti ejiya. Futhi ayizinzile ezixazululweni ezine-asidi ne-alkaline, futhi ayimelani nokushisa nokukhanya. I-CMC futhi isengozini yokuwohloka kwe-microbial, okuyenza ibe ukukhetha okufanele kancane emikhiqizweni edinga impilo yeshelufu ende.

Sengiphetha, i-HEC ne-CMC yizinhlobo ezimbili ze-cellulose ether ezinezakhiwo ezihlukile nezindlela zokusebenza. I-HEC incibilika kakhulu emanzini futhi isebenza kangcono njenge-ejenti yokujiya, kuyilapho i-CMC incibilika kancane emanzini futhi ingasebenzi kahle njenge-ejenti ejiya. I-HEC iphinde izinze kakhulu ezixazululweni ezine-asidi ne-alkaline, futhi imelana kakhulu nokushisa nokukhanya. I-CMC ayizinzile ezixazululweni ezine-asidi ne-alkaline, futhi ayimelani nokushisa nokukhanya. Womabili ama-polymers anezinhlobonhlobo zezinhlelo zokusebenza ekukhiqizeni izimonyo, imithi, imikhiqizo yokudla, iphepha, upende, nezinto zokunamathisela.
