Kuyini ukubonakala kwe-hydroxyethyl cellulose?

IHydroxyYethylcellulose (HEC) yi-nonionic, i-polymer ene-soluble ancibilike ethathwe ku-cellulose. Ngenxa yezakhiwo zayo ezihlukile zembongo, isetshenziswa kakhulu kwizimboni ezahlukahlukene kufaka phakathi ama-Pharmaceuticals, izimonyo nokwakha. Enye yezinto ezibalulekile ze-hydroxyethyl cellulose yayo yokubonakala, edlala indima ebalulekile ekutholeni ukusebenza kwayo kuzicelo ezahlukahlukene.

I-Viscosity iyisihlobo sokumelana noketshezi ukugeleza. Endabeni ye-hydroxyyethylcelcellellellulose, ukubonakala kwayo kuthintwa yizici eziningana, kufaka phakathi izinga lokushisa, izinga lokushisa kanye nezinga le-shear. Ukuqonda lezi zinto kubalulekile ekwakheni ukusetshenziswa kwe-HEC ngokwakhiwa okuhlukile.

I-viscoxyethylcelcellose ngokuqinile ngokugxila kwayo kusixazululo. Ngokuvamile, njengoba ukuncishiswa kwe-HEC kukhuphuka, ukubonakala kwayo kuyanda. Lokhu kuziphatha kuyindlela ejwayelekile yezixazululo ze-polymer futhi kuvame ukuchazwa yimodeli yoMthetho Wezamandla olandisa ukubonakala kokuqonda.

Ukushisa futhi kunomthelela obalulekile ekuboneni kwe-hydroxyethylll pullose solutions. Ezimweni eziningi, ukuhlakanipha kunciphisa ngokushisa okungeziwe. Lokhu kuzwela kokushisa kubalulekile ekusetshenzisweni kwezicelo lapho izinto zokwakha zidinga khona ukuguqulwa ekuboneni kwe-viscosity, njengasesikhathini sokukhiqiza noma lapho zisetshenziswa ezindaweni ezahlukene.

Izinga le-Shear kungenye into ebalulekile ethinta ukubonakala kwe-hydroxyethyl cellulose. Izinga le-Shear lisho isilinganiso lapho izingqimba ezisondelene ze-fluid zihambisa isihlobo komunye nomunye. I-Viscosity ye-HEC Solutions ivame ukukhombisa ukuziphatha okunciphise ukuncipha, okusho ukuthi njengoba isilinganiso se-shear sikhuphuka, i-visa iyehla. Le mpahla inenzuzo kuzinhlelo zokusebenza ezifana nezimbozo kanye nokunamathela lapho kutholakala khona kalula isicelo.

Isisindo samangqamuzana se-hydroxyethyl cellulose futhi sinquma ukubonakala kwaso. Ama-Heal Healind High aphezulu athambekele ekuboneni okuphezulu kokuhlushwa okunikezwe. Lesi sici sibalulekile lapho ukhetha ibanga elithile le-HEC ngesicelo esithile.

Emakhishini emithi, i-hydroxyyethylcellose ivame ukusetshenziswa njenge-ejenti ekhuthele ezindaweni zomthamo we-oral nezophezulu. I-viscosity ye-HEC iqinisekisa ukumiswa okufanele kwezinhlayiya futhi inikezela ukuvumelana okudingekayo kwe-dosing elula. Ngaphezu kwalokho, ukusebenza okunciphisayo kwe-Hear ka-HEC kungathuthukisa ukusakazeka kwezindlela eziphezulu.

Embonini yezimonyo, i-hydroxyyethylcellose isetshenziswa emikhiqizweni ehlukahlukene, kufaka phakathi ama-shampoos, ama-lotion kanye nokhilimu. Izakhiwo zayo zokusishintsha zisiza ukuthuthukisa ukuqina kanye nokuthungwa kwalezi zinhlaka, ngaleyo ndlela kuthuthukise isipiliyoni somsebenzisi jikelele.

Embonini yezokwakha, i-HydroxyYethylcellose ivame ukusetshenziswa njengomuntu omkhulu emikhiqizweni esekwe kuthusi. I-viscosity ye-HEC isiza ukulawula ukuhamba nokucutshungulwa kokuqukethwe ngesikhathi sohlelo lokusebenza. Lokhu kubaluleke kakhulu kwizicelo ezinjengezinamathiseli ze-tile nama-grouts.

I-viscoxyethyl celtulose iyipharamitha esemqoka ethinta ukusebenza kwayo kuzicelo ezihlukile. Ukuqonda izici ezithonya ukubonakala, njengokuhlushwa, izinga lokushisa, kanye nezinga le-shear, kubalulekile ukwenza kahle ukusetshenziswa kwe-HEC kwizimboni ezahlukahlukene. Njenge-polymer eguquguqukayo, i-hydroxyyethyl celtulose iyaqhubeka nokudlala indima ebalulekile ekwenzeni ngcono ukusebenza kwemikhiqizo ehlukahlukene kuyo yonke imboni ehlukahlukene.
