I-hydroxyethyl cellulose yenziwe ngani?

I-Hydroxyethyl cellulose (HEC) iyi-polymer yokwenziwa etholakala ku-cellulose, i-polysaccharide eyenzeka ngokwemvelo etholakala ezitshalweni.Kuyimpushana emhlophe, encibilika emanzini esetshenziswa njenge-ejenti ejiyayo, emisiwe, futhi eqinisayo emikhiqizweni eyahlukene, okuhlanganisa izimonyo, imithi, okokuhlanza, nemikhiqizo yokudla.

I-HEC ikhiqizwa ngokusabela kwe-cellulose nge-ethylene oxide, ikhemikhali etholakala ku-ethylene, igesi ye-hydrocarbon.I-ethylene oxide ihlangana namaqembu e-hydroxyl kuma-molecule e-cellulose, yakhe ukuxhumana kwe-ether phakathi kwama-molecule e-cellulose.Lokhu kusabela kudala i-polymer enesisindo samangqamuzana esiphezulu kuneselulosi yasekuqaleni, futhi kunikeza i-polymer izici zayo ezincibilika emanzini.

I-HEC isetshenziswa emikhiqizweni eyahlukene, okuhlanganisa izimonyo, imithi, okokuhlanza, nemikhiqizo yokudla.Kwezimonyo, isetshenziswa njenge-ejenti yokuqina, i-ejenti yokumisa, kanye ne-stabilizer.Kwezemithi, isetshenziswa njenge-binder, i-disintegrant, kanye ne-ejenti yokumisa.Kuma-detergents, isetshenziswa njenge-ejenti yokuqina, i-ejenti yokumisa, kanye ne-stabilizer.Emikhiqizweni yokudla, isetshenziswa njenge-ejenti yokuqina, i-ejenti yokumisa, kanye ne-stabilizer.

I-HEC iphinde isetshenziswe emisebenzini yokumba uwoyela negesi, lapho isetshenziselwa ukwandisa i-viscosity yokubhoboza uketshezi kanye nokunciphisa ukulahlekelwa kwamanzi kusukela ekubunjweni.Ibuye isetshenziswe ekwenzeni iphepha, lapho isetshenziselwa ukwandisa amandla nokuqina kwephepha.

I-HEC iyimpahla engenabuthi, engacasuli, futhi engeyona i-allergenic, okwenza iphephe ukusetshenziswa emikhiqizweni ehlukahlukene.Iyakwazi futhi ukubola, okuyenza ibe yinketho evumelana nemvelo.
