I-Ethylcellulose iyi-polymer esebenzayo etholakala ku-cellulose ngokusungulwa kwamaqembu e-ethyl.Lokhu kuguqulwa kunikeza izakhiwo ezihlukile ze-polymer, okuyenza ifaneleke ezinhlotsheni zezicelo zezimboni.Isici esibalulekile sokusebenzisa i-ethylcellulose emikhakheni ehlukene ukuqonda ukuziphatha kwayo kokuqedwa njengoba kuthinta ukucubungula kanye nokusetshenziswa kwayo.
Indlela yokuqeda i-ethylcellulose:
Izici zokuncibilika:
Ngenxa yemvelo ye-hydrophobic ye-ethyl substituent, i-ethylcellulose inyibilika kancane emanzini.Kodwa-ke, ikhombisa ukuncibilika ezinhlobonhlobo zezincibilikisi eziphilayo, okuyenza ifaneleke ikakhulukazi izinhlelo zokusebenza lapho ukumelana kwamanzi kubalulekile.Izinyibilikisi ezivamile ze-ethylcellulose zihlanganisa i-ethanol, i-ethyl acetate, i-methylene chloride, ne-toluene.Inqubo yokuhlakaza ihlanganisa ukuphula amandla e-intermolecular ngaphakathi kwe-polymer, okuvumela i-solvent ukuthi ingene futhi ihlakaze amaketanga e-polymer.
Izinto ezithinta ukuqedwa:
Kunezici eziningi ezithinta ukuqedwa kwe-ethylcellulose:
Ukukhetha isincibilikisi: Ukukhetha isincibilikisi kudlala indima ebalulekile enqubweni yokuchithwa.Izincibilikisi ezinokuhlangana okuphezulu kwe-ethylcellulose, njenge-ethyl acetate, zizosheshisa ukuqedwa.
Izinga lokushisa: Ukwenyuka kwezinga lokushisa ngokuvamile kwandisa izinga lokuchithwa ngoba kunikeza amandla engeziwe okusebenzelana kwe-polymer-solvent.Nokho, amazinga okushisa aphakeme angase abangele ukuwohloka.
Usayizi wezinhlayiyana ze-polymer: Usayizi wezinhlayiyana ezincane unikeza indawo enkulu yokusebenzelana kwe-solvent, okuholela ekuhlakazweni ngokushesha.Amasu okugaya afanelekile noma okunciphisa usayizi wezinhlayiyana angasetshenziswa ukuze kuthuthukiswe ukuncibilika.
Ibanga lePolymer: Ibanga le-ethylcellulose linqunywa okuqukethwe kwe-ethoxy nesisindo samangqamuzana, okuthinta ukunyibilika kwayo.Okuqukethwe okuphezulu kwe-ethoxy ngokuvamile kukhulisa ukuncibilika.
Ukunyakazisa noma ukuyaluza: Ukunyakazisa kwemishini noma ukuyaluza kusiza ukungena kwe-solvent ku-matrix ye-polymer futhi kusheshise inqubo yokuchithwa.
Izindlela ezivame ukusetshenziswa kakhulu zokuqeda:
Izindlela eziningi zingasetshenziswa ukuncibilikisa i-ethylcellulose:
Ukuxuba Isixazululo: Lokhu kuhlanganisa ukuxuba i-ethylcellulose ne-solvent efanelekile futhi ugovuze ingxube ize ichitheke ngokuphelele.Le ndlela ivame ukusetshenziswa ezindaweni zaselabhorethri.
I-Spray coating: Ekusetshenzisweni kwezimboni, izixazululo ze-ethylcellulose zivame ukulungiswa ngenqubo yokumboza isifutho.I-solvent iyahwamuka, ishiye ifilimu encane ye-ethylcellulose ku-substrate.
I-hot melt extrusion: Le nqubo ihlanganisa ukushisisa ingxube ye-ethylcellulose nezinye izakhi endaweni encibilikisiwe bese iyikhipha ngedayizi.Ngemuva kokupholisa, i-ethylcellulose iyaqina.
Ukuqonda izici nezindlela zokuhlakazeka kubalulekile ukuze uhlanganise i-ethylcellulose nezinhlelo ezithile zokusebenza.
Ukusetshenziswa okuyinhloko kwe-ethyl cellulose:
Imboni yezemithi:
I-Tablet Coating: I-Ethylcellulose isetshenziswa kakhulu njengento yokumboza amaphilisi ukuze anikeze ukukhululwa okulawulwayo nokuvikela isithako esisebenzayo semithi.
I-Microencapsulation: Iwubuchwepheshe be-microencapsulation obusetshenziswa ezinhlelweni zokulethwa kwezidakamizwa ukuvikela izidakamizwa ezicini zemvelo.
imboni yokudla:
Izindwangu Ezidliwayo: I-Ethylcellulose isetshenziswa njengesimbozo esidliwayo esithelweni nemifino ukuze kunwetshwe impilo yazo yeshalofu nokugcina ubusha.
Amapende nama-Coatings:
Ama-inks nama-Coatings: I-Ethylcellulose iyisithako esivamile kumayinki nama-coatings, ihlinzeka ngezakhiwo zokwenza ifilimu futhi ithuthukise ukwakheka kokuqina.
Imboni yePlastiki:
Isengezo sePolymer: Isetshenziswa njengesengezo kumapulasitiki ukuthuthukisa izici zabo zokucubungula, inikeze ukuguquguquka nokuqina.
Okunamathelayo:
I-Hot Melt Adhesives: I-Ethylcellulose isetshenziswa ekwakhiweni kwezinamathelisi ezincibilikayo ezishisayo ukuze zisize ukuthuthukisa ukunamathela kwazo nokuhlangana kwazo.
Imboni yezindwangu:
Usayizi Wendwangu: Ekucutshungulweni kwendwangu, i-ethylcellulose isetshenziswa ekulinganisweni ukuze kunikeze ukumbozwa okuyisivikelo emiculweni futhi kwandise amandla ayo.
umkhiqizo we-elekthronikhi:
Imishini ye-Photovoltaic: Ngenxa yezakhiwo zayo zefilimu kanye ne-dielectric, i-ethylcellulose ingasetshenziswa ukwenza amafilimu amancane emishini kagesi, kuhlanganise namaseli elanga.
Imikhiqizo yokunakekelwa komuntu siqu:
Ukwakhiwa kwezimonyo: Kusetshenziswa njenge-thickener kanye ne-stabilizer ekwakhiweni kwezimonyo ezifana nokhilimu nama-lotions.
Ukuphrinta kwe-3D:
Izibophezelo ekuphrinteni kwe-3D: I-Ethylcellulose ingasetshenziswa njengesihlanganisi kunqubo yokuphrinta ye-3D, esiza ukugcina ubuqotho besakhiwo bento ephrintiwe.
Imboni yamaphepha:
I-Paper coating: I-Ethyl cellulose isetshenziswa njengesimbozo sephepha ukuthuthukisa izakhiwo zayo ezingaphezulu, ukuthuthukisa ukuphrinta nokuhlinzeka ukumelana namanzi.
I-Ethylcellulose inezinhlelo zokusebenza ezimbonini ezihlukahlukene ngenxa yezimpawu zayo eziyingqayizivele zokuncibilika kanye nezakhiwo eziningi.Izindlela zokuhlakaza ziyisici esibalulekile ekufezekiseni amandla azo, okwenza izixazululo ezenzelwe izidingo ezithile.Njengoba isayensi ye-polymer iqhubeka nokuthuthuka, i-ethylcellulose ingase idlale indima ebalulekile ezinhlobonhlobo zezinhlelo zokusebenza ezintsha, ezifaka isandla ekwakhiweni kwezinto eziphambili kanye nemikhiqizo.
