I-Ethyl Cellulose

I-Ethyl cellulose iphuma ku-cellulose, i-polymer yemvelo etholakala ezitshalweni. Ikhiqizwa ngokusabela kwe-cellulose nge-ethyl chloride phambi kwe-catalyst. I-Ethyl cellulose isetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo eziyingqayizivele kanye nokuhlukahluka. Nazi ezinye izici ezibalulekile kanye nokusetshenziswa kwe-ethyl cellulose:

1. Ukungancibiliki emanzini: I-Ethyl cellulose ayincibiliki emanzini, okwenza ifanelekele izinhlelo zokusebenza lapho kudingeka ukumelana namanzi. Lesi sakhiwo sivumela futhi ukusetshenziswa kwayo njengesimbozo sokuzivikela emithini yemithi nanjengento evimbelayo ekufakweni kokudla.
2. I-Solubility ku-Organic Solvents: I-Ethyl cellulose inyibilika ezinhlobonhlobo zezinyibilikisi zemvelo, okuhlanganisa i-ethanol, i-acetone, ne-chloroform. Lokhu kuncibilika kwenza kube lula ukucubungula nokwenza imikhiqizo ehlukahlukene, efana nama-coatings, amafilimu, noyinki.
3. Ikhono Lokwenza Ifilimu: I-Ethyl cellulose inamandla okwenza amafilimu aguquguqukayo futhi aqinile lapho omisiwe. Lesi sakhiwo sisetshenziswa ezinhlelweni ezifana nezingubo zethebhulethi emithini yemithi, lapho inikeza ungqimba oluvikelayo lwezithako ezisebenzayo.
4. I-Thermoplasticity: I-Ethyl cellulose ibonisa ukuziphatha kwe-thermoplastic, okusho ukuthi ingathanjiswa futhi ibunjwe lapho ishiswa bese iqina lapho ipholisa. Lesi sakhiwo siyenza ifanelekele ukusetshenziswa kuma-adhesive ancibilikayo ashisayo namapulasitiki abumbekayo.
5. Ukungena Kwamakhemikhali: I-Ethyl cellulose ayisebenzi ngamakhemikhali futhi imelana nama-asidi, ama-alkali, kanye nezinyibilikisi eziningi eziphilayo. Lesi sakhiwo siyenza ifanelekele ukusetshenziswa ekwakhiweni lapho ukuzinza nokuhambisana nezinye izithako kubalulekile.
6. I-Biocompatibility: I-Ethyl cellulose ngokuvamile ithathwa njengephephile (i-GRAS) ukuze isetshenziswe emikhiqizweni yezemithi, yokudla, neyezimonyo. Ayinabuthi futhi ayifaki ingozi yemiphumela emibi uma isetshenziswa njengoba kuhlosiwe.
7. Ukukhishwa Okulawulwayo: I-Ethyl cellulose ivame ukusetshenziswa ekwakhiweni kwemithi ukulawula ukukhishwa kwezithako ezisebenzayo. Ngokulungisa ukujiya kwe-ethyl cellulose enamathela kumaphilisi noma ama-pellets, izinga lokukhishwa kwezidakamizwa lingashintshwa ukuze kuzuzwe amaphrofayili anwetshiwe noma aqhubekayo.
8. I-Binder ne-Thickener: I-Ethyl cellulose isetshenziswa njenge-binder kanye ne-thickener emisebenzini ehlukahlukene, kuhlanganise noyinki, okokunamathela, nezinamatheliso. Ithuthukisa izakhiwo ze-rheological of formulations futhi isiza ukufeza ukuvumelana okufunayo kanye ne-viscosity.

I-ethyl cellulose iyi-polymer eguquguqukayo enezinhlobonhlobo zokusetshenziswa ezimbonini ezifana nemithi, ukudla, izimonyo, okokunamathela, nezinamathiselo. Inhlanganisela yayo eyingqayizivele yezakhiwo iyenza ibe isithako esibalulekile ekwakhiweni okuningi, lapho inikela khona ekuzinzeni, ekusebenzeni, nasekusebenzeni.
