Inqubo yokulungiselela i-Ethyl cellulose microcapsule
Ama-microcapsules e-Ethyl cellulose ayizinhlayiya ezincane kakhulu noma amaphilisi anesakhiwo segobolondo eliyinhloko, lapho isithako esisebenzayo noma umthwalo okhokhelwayo umbozwa ngaphakathi kwegobolondo le-ethyl cellulose polymer. Lawa ma-microcapsules asetshenziswa ezimbonini ezahlukahlukene, okubandakanya ezemithi, ukudla, izimonyo, nezolimo, ukuze kukhishwe okulawulwayo noma ukulethwa okuhlosiwe kwento ehlanganisiwe. Nakhu ukubuka konke okujwayelekile kwenqubo yokulungiselela ama-microcapsules e-ethyl cellulose:
1. Ukukhethwa Kwezinto Ezibalulekile:
- Into esemqoka, eyaziwa nangokuthi isithako esisebenzayo noma umthwalo okhokhelwayo, ikhethwa ngokusekelwe kuhlelo olufiswayo nezici zokukhishwa.
- Kungaba okuqinile, uketshezi, noma igesi, kuye ngokusetshenziswa okuhlosiwe kwama-microcapsules.
2. Ukulungiswa Kwezinto Ezibalulekile:
- Uma i-core material iqinile, kungase kudingeke ukuthi igaywe noma yenziwe nge-micronized ukuze kuzuzwe ukusabalalisa usayizi wezinhlayiyana oyifunayo.
- Uma i-core material iwuketshezi, kufanele ihlukaniswe i-homogenized noma ihlakazwe ku-solvent efanelekile noma isixazululo sokuthwala.
3. Ukulungiswa Kwesixazululo Se-Ethyl Cellulose:
- I-Ethyl cellulose polymer incibilika ku-solvent yemvelo eguquguqukayo, njenge-ethanol, i-ethyl acetate, noma i-dichloromethane, ukwenza isixazululo.
- Ukuhlushwa kwe-ethyl cellulose esixazululweni kungahluka kuye ngokuthi ugqinsi olufunwayo lwegobolondo le-polymer kanye nezici zokukhululwa zama-microcapsules.
4. Inqubo ye-Emulsification:
- Isixazululo sezinto eziyisisekelo sengezwe kusisombululo se-ethyl cellulose, futhi ingxube ifakwe emulsified ukuze yakhe i-emulsion yamafutha emanzini (O/W).
- I-Emulsification ingafinyelelwa kusetshenziswa i-mechanical agitation, i-ultrasonication, noma i-homogenization, ephula isisombululo sezinto eziyinhloko sibe amaconsi amancane ahlakazekile kusixazululo se-ethyl cellulose.
5. I-Polymerization noma Ukuhlanganiswa Kwe-Ethyl Cellulose:
- Ingxube ye-emulsified ibe isingaphansi kwe-polymerization noma inqubo yokuqinisa ukuze yakhe igobolondo le-ethyl cellulose polymer elizungeze amaconsi abalulekile.
- Lokhu kungafezwa ngokuhwamuka kwe-solvent, lapho i-solvent ephilayo eguquguqukayo isuswa ku-emulsion, ishiya ama-microcapsules aqinile.
- Kungenjalo, ama-cross-linking agents noma izindlela zokuhlanganisa zingase zisetshenziswe ukuze kuqiniswe igobolondo le-ethyl cellulose kanye nokusimamisa ama-microcapsules.
6. Ukuwasha nokomisa:
- Ama-microcapsules akhiwe ahlanzwa nge-solvent efanelekile noma amanzi ukuze asuse noma yikuphi ukungcola okusele noma izinto ezingaphenduliwe.
- Ngemuva kokugeza, ama-microcapsules omisiwe ukuze asuse umswakama futhi aqinisekise ukuzinza ngesikhathi sokugcina nokuphatha.
7. Ukuhlukaniswa kwezinhlamvu nokulawulwa kwekhwalithi:
- Ama-microcapsules e-ethyl cellulose abonakala ngokusatshalaliswa kosayizi wawo, i-morphology, ukusebenza kahle kwe-encapsulation, i-kinetics yokukhululwa, nezinye izakhiwo.
- Ukuhlolwa kokulawula ikhwalithi kuyenziwa ukuze kuqinisekiswe ukuthi ama-microcapsules ahlangabezana nezicaciso ezifiselekayo kanye nenqubo yokusebenza yohlelo oluhlosiwe.
Isiphetho:
Inqubo yokulungiselela ama-microcapsules e-ethyl cellulose ihilela ukufakwa kwe-emulsification yezinto eziyinhloko kusixazululo se-ethyl cellulose, okulandelwa yi-polymerization noma ukuqina kwegobolondo le-polymer ukuze kuhlanganiswe into eyinhloko. Ukukhetha ngokucophelela izinto zokwakha, amasu e-emulsification, kanye nemingcele yenqubo kubalulekile ukuze kuzuzwe ama-microcapsules afanayo futhi azinzile anezici ezifiselekayo zezinhlelo zokusebenza ezihlukahlukene.
