Inkqubo yokulungiselela i-Ethyl cellulose microcapsule

I-Ethyl cellulose microcapsules ngamasuntswana amancinci okanye i-capsules ene-core-shell structure, apho isithako esisebenzayo okanye i-payload ifakwe ngaphakathi kwe-ethyl cellulose polymer shell. Ezi microcapsules zisetyenziswa kumashishini ahlukeneyo, kubandakanywa amayeza, ukutya, izimonyo, kunye nezolimo, ukukhutshwa okulawulwayo okanye ukuhanjiswa okujoliswe kuyo kwezinto ezifakiweyo. Nantsi inkcazo jikelele yenkqubo yokulungiselela i-ethyl cellulose microcapsules:

1. Ukukhethwa kweMathiriyeli enguNdoqo:

• Izinto ezingundoqo, ezaziwa ngokuba sisithako esisebenzayo okanye umthwalo wokuhlawula, ukhethwa ngokusekelwe kwisicelo esifunwayo kunye neempawu zokukhulula.
• Inokuba yinto eqinileyo, ulwelo, okanye igesi, kuxhomekeke kusetyenziso olucetywayo lwemicrocapsules.

2. Ukulungiswa kwezinto ezingundoqo:

• Ukuba i-core material iqinile, inokufuna ukuba iphantsi okanye i-micronized ukufezekisa ukuhanjiswa kwesayizi ye-particle efunekayo.
• Ukuba i-core material ilulwelo, kufuneka i-homogenized okanye ihlakazwe kwi-solvent efanelekileyo okanye isisombululo sokuthwala.

3. Ukulungiswa kwe-Ethyl Cellulose Solution:

• I-Ethyl cellulose polymer inyibilika kwi-solvent eguqukayo ye-organic, njenge-ethanol, i-ethyl acetate, okanye i-dichloromethane, ukwenza isisombululo.
• Ukuxinwa kwe-ethyl cellulose kwisisombululo kunokuhluka ngokuxhomekeke kubukhulu obufunwayo begobolondo yepolymer kunye neempawu zokukhululwa kwe-microcapsules.

4. Inkqubo ye-Emulsification:

• Isisombululo sezinto eziphambili zongezwa kwisisombululo se-ethyl cellulose, kwaye umxube ufakwe emulsified ukwenza i-emulsion yeoli emanzini (O / W).
• I-Emulsification inokufezekiswa ngokusebenzisa i-mechanical agitation, i-ultrasonication, okanye i-homogenization, ephula isisombululo sezinto ezingundoqo zibe ngamaconsi amancinci ahlakazwe kwisisombululo se-ethyl cellulose.

5. Ukwenziwa kwePolymerization okanye ukuDityaniswa kwe-Ethyl Cellulose:

• Umxube we-emulsified ke uphantsi kwe-polymerization okanye inkqubo yokuqinisa ukwenza i-ethyl cellulose polymer iqokobhe elijikeleze amathontsi ezinto ezingundoqo.
• Oku kunokufezekiswa nge-evaporation ye-solvent, apho i-solvent ye-organic eguquguqukayo isuswa kwi-emulsion, ishiya emva kwe-microcapsules eqinile.
• Ngenye indlela, i-agent edibanisa i-cross-link okanye iindlela zokudibanisa zingasetyenziselwa ukuqinisa i-ethyl cellulose shell kunye nokuzinzisa i-microcapsules.

6. Ukuhlamba kunye nokomisa:

• Ii-microcapsules ezibunjiweyo zihlanjwa nge-solvent efanelekileyo okanye amanzi ukuze kususwe nayiphi na into engcolileyo eseleyo okanye izinto ezingenakulinganiswa.
• Emva kokuhlamba, ii-microcapsules zomisiwe ukuze zisuse umswakama kwaye ziqinisekise ukuzinza ngexesha lokugcinwa kunye nokuphatha.

7. Ubulinganiswa kunye noLawulo loMgangatho:

• I-ethyl cellulose microcapsules ibonakaliswe ngokusabalalisa ubungakanani bayo, i-morphology, i-encapsulation efficient, i-kinetics yokukhululwa, kunye nezinye iimpawu.
• Iimvavanyo zokulawula umgangatho ziqhutyelwa ukuqinisekisa ukuba i-microcapsules ihlangabezana neenkcukacha ezifunwayo kunye neendlela zokusebenza kwisicelo esijoliswe kuyo.

Isiphelo:

Inkqubo yokulungiselela i-ethyl cellulose microcapsules ibandakanya i-emulsification yezinto eziphambili kwisisombululo se-ethyl cellulose, elandelwa yi-polymerization okanye ukuqina kwegobolondo ye-polymer ukuze ifake izinto ezingundoqo. Ukukhethwa ngokucokisekileyo kwemathiriyeli, ubuchule be-emulsification, kunye neeparitha zenkqubo kubalulekile ukufezekisa ii-microcapsules ezifanayo kunye nezinzile kunye neempawu ezifunwayo kwizicelo ezahlukeneyo.
