Iyini i-viscosity ye-hydroxyethyl cellulose?

IHydroxyethylcellulose (HEC) i-nonionic, i-polymer encibilika emanzini etholakala ku-cellulose. Ngenxa yezakhiwo zayo eziyingqayizivele ze-rheological, ivame ukusetshenziswa ezimbonini ezihlukahlukene ezihlanganisa ezemithi, izimonyo nezokwakha. Enye yezinto ezibalulekile ze-hydroxyethyl cellulose yi-viscosity yayo, edlala indima ebalulekile ekunqumeni ukusebenza kwayo ezinhlotsheni ezahlukene.

I-viscosity isilinganiso sokumelana koketshezi nokugeleza. Endabeni ye-hydroxyethylcellulose, i-viscosity yayo ithinteka yizici eziningana, kuhlanganise nokugxila, izinga lokushisa kanye nesilinganiso se-shear. Ukuqonda lezi zici kubalulekile ekuthuthukiseni ukusetshenziswa kwe-HEC ekwakhiweni okuhlukene.

I-viscosity ye-hydroxyethylcellulose incike kakhulu ekugxilweni kwayo esixazululweni. Ngokuvamile, njengoba ukuhlushwa kwe-HEC kwanda, i-viscosity yayo nayo iyanda. Lokhu kuziphatha kujwayelekile kwezixazululo ze-polymer futhi kuvame ukuchazwa imodeli yomthetho wamandla ehlobene ne-viscosity nokugxilisa ingqondo.

Izinga lokushisa libuye libe nomthelela omkhulu ku-viscosity yezixazululo ze-hydroxyethyl cellulose. Ezimweni eziningi, i-viscosity iyancipha ngokukhuphuka kwezinga lokushisa. Lokhu kuzwela kwezinga lokushisa kubalulekile ezinhlelweni zokusebenza lapho izinto ezidingekayo zidinga ushintsho ku-viscosity, njengalapho kukhiqizwa noma lapho kusetshenziswa ezindaweni ezihlukene.

Izinga le-Shear lingenye into ebalulekile ethinta i-viscosity ye-hydroxyethyl cellulose. Izinga le-Shear lisho izinga lapho izingqimba zoketshezi eziseduze zinyakaza zihlobene. I-viscosity yezixazululo ze-HEC ngokuvamile ibonisa ukuziphatha kokugunda kwe-shear, okusho ukuthi njengoba izinga lokugunda likhuphuka, i-viscosity iyancipha. Lesi sakhiwo sinenzuzo ezinhlelweni ezifana nezingubo zokunamathisela kanye nama-adhesives lapho kulula ukufaka isicelo.

Isisindo samangqamuzana e-hydroxyethyl cellulose siphinde sinqume i-viscosity yayo. Isisindo samangqamuzana aphezulu ama-HEC avame ukuba nama-viscosity aphezulu ekugxilweni okunikeziwe. Lesi sici sibalulekile lapho kukhethwa ibanga elithile le-HEC lohlelo oluthile.

Ekwakhekeni kwemithi, i-hydroxyethylcellulose ivamise ukusetshenziswa njenge-ejenti yokuqina emafomu omthamo womlomo kanye ne-topical. I-viscosity ye-HEC iqinisekisa ukumiswa okufanele kwezinhlayiya futhi inikeza ukuvumelana okudingekayo ukuze kube lula ukudosa. Ngaphezu kwalokho, ukuziphatha kokunciphisa i-shear kwe-HEC kungathuthukisa ukusabalala kokwakheka kwezihloko.

Embonini yezimonyo, i-hydroxyethylcellulose isetshenziswa emikhiqizweni ehlukahlukene, kufaka phakathi ama-shampoos, ama-lotions nama-creams. Izici zayo zokuguqula i-viscosity zisiza ukuthuthukisa ukuzinza nokuthungwa kwalezi zakhiwo, ngaleyo ndlela kuthuthukise ulwazi olunzulu ngomsebenzisi.

Embonini yezokwakha, i-hydroxyethylcellulose ivame ukusetshenziswa njenge-thickener emikhiqizweni esekwe usimende. I-viscosity ye-HEC isiza ukulawula ukugeleza nokucutshungulwa kwezinto ngesikhathi sokufaka isicelo. Lokhu kubaluleke kakhulu ekusetshenzisweni okufana nokunamathiswa kwamathayili nama-grouts.

I-viscosity ye-hydroxyethyl cellulose iyipharamitha eyinhloko ethinta ukusebenza kwayo ezinhlelweni ezahlukene. Ukuqonda izici ezithonya i-viscosity, njengokugxila, izinga lokushisa, nezinga lokugunda, kubalulekile ekuthuthukiseni ukusetshenziswa kwe-HEC ezimbonini ezihlukahlukene. Njengepolymer eguquguqukayo, i-hydroxyethyl cellulose iyaqhubeka nokubamba iqhaza elibalulekile ekuthuthukiseni ukusebenza kwemikhiqizo ehlukahlukene kuzo zonke izimboni ezahlukahlukene.
