I-Celluloseether

I-Cellulose ether iwumndeni wokuphuma kwe-cellulose eguqulwe ngamakhemikhali esetshenziswa kakhulu emikhiqizweni eyahlukene yezimboni nezabathengi. Ama-cellulose ether akhiqizwa ngokushintsha amakhemikhali imicu yemvelo ye-cellulose noma i-pulp, ngokuvamile ngokusabela nge-alkali noma i-ejenti etherifying. Ama-molecule e-cellulose aguquliwe athuthukise ukuncibilika, ukugcinwa kwamanzi, kanye nezakhiwo ezijiya, eziwenza abe usizo ohlotsheni lwezinhlelo zokusebenza.

Ezinye izinhlelo zokusebenza ezijwayelekile ze-cellulose ethers zifaka:

Ukwakhiwa: Ama-cellulose ether asetshenziswa kakhulu embonini yezokwakha njengezithasiselo zikasimende, udaka, nezinye izinto zokwakha. Zithuthukisa ukusebenza, ukunamathela, nokugcinwa kwamanzi kwalezi zinto ezisetshenziswayo, ezingathuthukisa ikhwalithi nokuqina komkhiqizo wokugcina.

Ukudla neziphuzo: Ama-cellulose ether asetshenziswa njengama-ejenti ajiyayo, iziqinisi, nama-emulsifiers ezinhlobonhlobo zokudla neziphuzo, okuhlanganisa amasaladi okugqoka, amasoso, u-ayisikhilimu, nezinto ezibhakwayo.

Ezemithi: Ama-cellulose ether asetshenziswa njengezihlanganisi ekwakhiweni kwemithi ukuze kuthuthukiswe ukuzinza, ukunyibilika, kanye nokutholakala kwe-bioavailability kwezithako ezisebenzayo.

Imikhiqizo yokunakekela umuntu: Ama-cellulose ether asetshenziswa ezinhlobonhlobo zemikhiqizo yokunakekela umuntu, njengamashampu, okokugcoba, nezimonyo, ukuze anikeze ukuthungwa, ukubukeka, nezinye izici ezifiselekayo.

Ezinye izinhlobo ezivamile ze-cellulose ethers zihlanganisa:

I-Methyl cellulose (MC): I-MC iyi-ether ye-cellulose encibilika emanzini esetshenziswa kakhulu njenge-ejenti ejiyayo, isibopho, kanye ne-emulsifier kuhlu lwemikhiqizo yezimboni nezabathengi.

I-Hydroxyethyl cellulose (HEC): I-HEC iyi-ether ye-cellulose encibilika emanzini evame ukusetshenziswa njenge-ejenti ejiyayo kanye ne-stabilizer emikhiqizweni yokunakekelwa komuntu siqu kanye nokwakhiwa kwemithi.

I-Carboxymethyl cellulose (CMC): I-CMC iyi-ether ye-cellulose encibilika emanzini esetshenziswa kabanzi njenge-ejenti ejiyayo, i-binder, kanye ne-stabilizer ezinhlobonhlobo zezimboni nemikhiqizo yabathengi, okuhlanganisa ukudla, iziphuzo, nemikhiqizo yokunakekelwa komuntu siqu.
