IHydroxyethyl cellulose (HEC) iyinhlanganisela esetshenziswa kabanzi enezinhlelo zokusebenza ezahlukahlukene kuzo zonke izimboni. Eyaziwa nangokuthi i-hydroxyethylcellulose noma i-HEC, ingeyomndeni we-cellulose ethers, etholakala ku-cellulose ngokuguqulwa kwamakhemikhali. Lokhu kuguqulwa kuhilela ukwethulwa kwamaqembu e-hydroxyethyl kumgogodla we-cellulose, okuthuthukisa ukunyibilika kwawo nezinye izici zokusebenza. Nakuba i-hydroxyethyl cellulose iyigama elivamile, ingase futhi ibhekiselwe kulo ngamanye amagama ezimweni ezehlukene, kuye ngokuthi isetshenziswa kanjani kanye nemboni ethile ehilelekile.
Emkhakheni wamakhemikhali nezimboni, i-hydroxyethyl cellulose ingaziwa ngegama layo lamakhemikhali, i-ethyl hydroxyethyl cellulose noma i-hydroxyethyl cellulose nje. Kwezohwebo nakwezohwebo, kungase kuhambisane namagama emikhiqizo ahlukahlukene noma izimpawu zokuthengisa, kuye ngomkhiqizi noma umphakeli. Lawa magama angafaka i-Natrosol, i-Cellosize, i-Bermocoll, namanye, kuye ngokuthi inkampani ekhiqizayo noma esabalalisa umkhiqizo.
Ezakhiweni zokwakha nezokwakha, i-hydroxyethyl cellulose ivame ukusetshenziswa njenge-ejenti yokuqina, insiza yokugcina amanzi, kanye nesilungisi se-rheology emikhiqizweni esekwe usimende, njengodaka, ama-grouts, nama-cementitious coatings.
Kwezemithi kanye nemikhiqizo yokunakekelwa komuntu siqu, i-hydroxyethyl cellulose isebenza njengesithako esisebenza ngezindlela eziningi esisetshenziswa ekwenziweni okufana nokhilimu, ama-lotions, ama-shampoos, nezixazululo ze-ophthalmic. Phakathi kwalezi zimboni, ingase ifakwe ohlwini lwamalebula omkhiqizo ngegama layo lekhemikhali noma njenge-ejenti ejiyayo, i-stabilizer, noma i-viscosity modifier. Amanye amagama angase afake i-Natrosol, i-Cellosize, noma i-HEC nje, kuye ngezivumelwano zokufaka uphawu noma zokulebula zomkhiqizi.
Embonini yokudla neziphuzo, i-hydroxyethyl cellulose isetshenziswa njenge-thickener, stabilizer, noma emulsifier emikhiqizweni eyahlukene kusukela kumasoso nezindwangu zokugqoka kuya eziphuzweni naku-ayisikhilimu. Kulo mongo, ingabizwa nje ngokuthi i-HEC noma ngamagama ayo emikhiqizo uma kusetshenziswa imikhiqizo ethile yezentengiso.
kuyilapho i-hydroxyethyl cellulose iyigama lekhemikhali elijwayelekile lale nhlanganisela, ingaziwa ngamanye amagama ahlukahlukene kuye ngemboni, umongo, kanye nokusebenza okuqondile. Lawa magama angabandakanya amagama okuhweba, amagama emikhiqizo, noma izincazelo ezijwayelekile zomsebenzi noma izakhiwo zayo. Ngaphandle kwegama elisetshenzisiwe, i-hydroxyethyl cellulose isalokhu iyisithako esibalulekile nesiguquguqukayo esisetshenziswa kabanzi ezimbonini eziningi.
