I-viscosity ye-hydroxyethyl cellulose

I-Hydroxyethyl cellulose (HEC) iyi-polymer e-nonionic, encibilika emanzini esetshenziswa kabanzi njenge-thickener, stabilizer, kanye ne-binder ezimbonini ezahlukahlukene, ezihlanganisa ezemithi, izimonyo, nezokwakha. I-viscosity yayo idlala indima ebalulekile ekunqumeni ukusebenza kwayo kulezi zinhlelo zokusebenza.

I-viscosity ye-HEC inqunywa izici eziningi, okuhlanganisa izinga layo lokushintshwa (DS), isisindo samangqamuzana, ukugxila, kanye ne-pH. I-degree of substitution ibhekisela enanini lamaqembu e-hydroxyethyl angezwe ku-molecule ye-cellulose, kuyilapho isisindo se-molecule sibhekisela kusayizi wamaketanga e-polymer. Ukugxila kwe-HEC esixazululweni nakho kuthinta i-viscosity yayo, ngokugxila okuphezulu okuholela ekubonakaleni okuphezulu. I-pH yesisombululo ingaba nomthelela ku-viscosity, ngamavelu e-pH aphezulu ngokuvamile aholela ekunciphiseni kwe-viscosity.

I-viscosity ye-HEC ingalinganiswa kusetshenziswa i-viscometer, ekala ukumelana noketshezi olugeleza. Izinhlobo ezahlukene zama-viscometer zingasetshenziswa, okuhlanganisa ama-viscometer ajikelezayo nama-capillary viscometers, kuye ngohlelo olukhethekile kanye nebanga le-viscosity lentshisekelo.

Ngokuvamile, i-viscosity ephakeme i-HEC ikhethwa ezinhlelweni lapho ukuqina nokuzinza kubaluleke kakhulu, njengasekwenziweni kwemithi, izimonyo, kanye nemikhiqizo yokunakekelwa komuntu siqu. Isibonelo, i-HEC ene-viscosity ephezulu ivame ukusetshenziswa kuma-shampoos nama-conditioner ukuze kuthuthukiswe ukuthungwa nokusebenza kwawo, kanye nakumakhilimu nama-lotions ukuze kunikeze umuzwa obushelelezi, wokunethezeka.

Embonini yezokwakha, i-HEC isetshenziswa njenge-ejenti yokuqinisa kanye nokugcina amanzi emikhiqizweni esekwe usimende, efana nodaka, ama-grouts, nokhonkolo. I-viscosity ye-HEC kulezi zicelo ibalulekile ekufinyeleleni ukusebenza okufunayo, ukunamathela, nokuvumelana komkhiqizo wokugcina.

I-viscosity ye-HEC ingabuye ishintshwe ngezindlela ezihlukahlukene zamakhemikhali nezomzimba, okuhlanganisa ukuxhumanisa, i-acid hydrolysis, nokuxuba namanye ama-polymer. Lezi zinguquko zingashintsha izakhiwo ze-HEC futhi ziphumele ekusebenzeni okuthuthukisiwe ezinhlelweni ezithile.

Kafushane, i-viscosity ye-HEC iyisici esibalulekile ekunqumeni ukusebenza kwayo ezinhlelweni ezihlukahlukene. Izinga lokushintsha, isisindo samangqamuzana, ukugxila, kanye ne-pH konke kudlala indima ekunqumeni i-viscosity yayo, engalinganiswa kusetshenziswa i-viscometer. Izimboni ezihlukene kanye nezinhlelo zokusebenza zingadinga amazinga ahlukene we-viscosity, futhi ukuguqulwa ku-HEC kungenziwa ukuze kuthuthukiswe ukusebenza kwayo ezinhlelweni ezithile.
