Inqubo ye-ethylpulese microcappule ukulungiselela i-microcapsapsose

I-Ethyl Cellulose Microcapsops iyizinhlayiya ze-microscopic noma ama-capsule ngesakhiwo se-core-shell, lapho isithako esisebenzayo noma esikhokhelwayo singena ngaphakathi kwe-ethyl cellmer shell. Lawa ma-microcapsaps asetshenziswa ezimbonini ezahlukahlukene, okubandakanya ama-Pharmaceuticals, ukudla, izimonyo kanye nezolimo, ukukhishwa okulawulwayo noma ukulethwa okuhlosiwe kwento evunyelwe. Nakhu ukubuka konke okujwayelekile kwenqubo yokulungiselela ye-Ethyllulose Microcapsops:

1. Ukukhetha kwezinto ezibalulekile:

• Izinto ezibalulekile, ezaziwa nangokuthi isithako esisebenzayo noma i-payload, zikhethiwe ngokususelwa kuhlelo lokusebenza olufunayo kanye nokukhishwa kwezimpawu.
• Kungaba okuqinile, okuwuketshezi, noma igesi, kuya ngokusetshenziswa okuhlosiwe kwama-microcappules.

2. Ukulungiselela izinto ezibalulekile:

• Uma impahla eyisisekelo iqinile, kungadinga ukuba yinhlabathi noma i-mainronised ukuze kufinyelelwe ukusatshalaliswa kosayizi oyindilinga oyifisayo.
• Uma impahla eyisisekelo iwuketshezi, kufanele ibe yi-homogenized noma ihlakazeke kwi-solvent efanelekile noma isixazululo senkampani yenethiwekhi.

3. Ukulungiselela isixazululo se-ethyl cellulose:

• I-Ethyl Cellulose polymer ichithwa ku-solvent eguquguqukayo ye-organic, njenge-ethanol, ethyl acetate, noma i-dichloromethane, ukwakha ikhambi.
• Ukuhlushwa kwe-ethyl cellulose kusisombululo kungahluka ngokuya ngobukhulu obufunayo be-polymer igobolondo kanye nezimpawu zokukhishwa kwama-microcapsops.

4. Inqubo ye-emulsafication:

• Isixazululo sezinto ezibonakalayo esiyisisekelo sengezwe kwisixazululo se-ethyl cellulose, futhi ingxube ivezwa ukwakha i-emulsion (O / W) emulsion.
• I-Emulsation ingatholakala kusetshenziswa ukuguga kwemishini, i-ultrasonication, noma i-homogenization, ephula isixazululo sezinto ezibonakalayo esiyisisekelo kumaconsi amancane ahlakazeke kwisisombululo se-ethyllulose.

I-5. I-Polymerization noma ukuqina kwe-ethyl cellulose:

• Ingxube ekhuphukile ihanjiswa nge-polymerization noma inqubo yokuqina yokwakha i-ethyl cellulose polymer shell ezungeze amaconsi wezinto ezibonakalayo.
• Lokhu kungatholwa ngokuvela kwe-solvent, lapho i-slouseile organic solvent isuswa emulsion, ishiye ngemuva kwe-microcappules eqinile.
• Ngenye indlela, ama-ejenti axhumanisa ama-cross-activing noma amasu okubumbana angaqashwa ukuze aqinise i-ethyl cellulose igobolondo futhi aqinise ama-microcapsules.

6. Ukugeza nokomisa:

• Ama-microcapsabales asungulwa agezwa nge-solvent efanele noma amanzi okususa noma yikuphi ukungcola okusele noma izinto ezingezona ezenziwe.
• Ngemuva kokugeza, ama-microcapsops amiswa ukususa umswakama futhi aqinisekise ukuqina ngesikhathi sokugcina nokuphatha.

7. Isimo nokulawulwa kwekhwalithi:

• I-ethyl cellulose microcapsoses ibonakala ngokusatshalaliswa kwazo ngosayizi, i-morphology, ukusebenza kahle kwe-encyology, ukukhulula ama-kinetics, nezinye izakhiwo.
• Ukuhlolwa kokulawulwa kwekhwalithi kwenziwa ukuze kuqinisekiswe ukuthi ama-microcapsops ahlangabezana nezincazelo ezifiselekayo nezinqubo zokusebenza kohlelo lokusebenza okuhlosiwe.

Isiphetho:

Inqubo yokulungiselela ye-Ethyllulose microcapsoses ifaka ama-emulsation of the ecore material esikhaleni se-ethyl cellulose, elandelwa yi-polymerization noma ukuqina kwe-polymer igobolondo ukuze kuhlanganise nezinto ezibalulekile. Ukukhethwa ngokucophelela kwezinto zokwenziwa, amasu we-emulsaturatiefication, kanye namapharamitha enqubo kubalulekile ukuze kufinyelelwe ama-microcappulles afanayo nezakhiwo ezifunwayo ngezicelo ezahlukahlukene.

ku-on.
