Ethyl Cellulose Microhrapsule Npaj Txheej Txheem

Ethyl cellulose microcapsules yog cov qauv me me los yog cov khoom siv plhaub ua kom nquag plias lossis payload yog ething cellulose plhaub polymer. Cov microcapsules no tau siv nyob rau hauv ntau yam kev lag luam, suav nrog cov tshuaj, zaub mov, tshuaj pleev ib ce, thiab kev ua liaj ua teb, rau kev xa khoom ntawm cov khoom encapsulated. Ntawm no yog ib qho kev txhawb nqa dav dav ntawm kev npaj cov txheej txheem rau Ethyl cellulose microcapsules:

1. Xaiv cov khoom siv tseem ceeb:

• Cov khoom siv tseem ceeb, tseem hu ua cov khoom siv nquag lossis payload, yog xaiv raws li daim ntawv thov xav tau thiab tso tawm cov yam ntxwv.
• Nws tuaj yeem yog cov khoom siv, kua, lossis roj, nyob ntawm qhov kev npaj siv ntawm cov microCapsules.

2. Npaj cov khoom siv tseem ceeb:

• Yog tias cov khoom siv tseem ceeb yog ib qho khoom siv, nws yuav tsum tau ua av lossis micronized kom ua tiav qhov xav tau qhov ntsuas qhov qis.
• Yog tias cov khoom siv tseem ceeb yog cov kua, nws yuav tsum yog homogenized los yog dispersed nyob rau hauv ib cov kuab tshuaj uas tsis haum lossis cov cab kuj daws teeb meem.

3. Kev npaj ntawm Ethyl cellulose kev daws teeb meem:

• Ethyl cellulose polymer yog yaj nyob rau hauv lub zog loj heev, xws li ethanol, ethyl acetate, lossis dichhloromethane, los tsim kev daws teeb meem.
• Qhov kev pom zoo ntawm cov tshuaj ethylose hauv kev daws yuav sib txawv raws li qhov xav tau tuab ntawm cov qauv ntawm cov microCapsules.

4. Emulsification Txheej Txheem:

• Cov khoom siv tseem ceeb tau ntxiv rau cov tshuaj tua kab, thiab cov sib xyaw yog emulsified los ua cov roj-hauv-dej (O / W) emulsion.
• Emulsification tuaj yeem ua tiav siv kev ntxhov siab, lossis homogenization, uas tawg cov khoom tseem ceeb rau hauv cov tee tshuaj me me hauv cov tshuaj tiv thaiv kab mob hauv lub ethyl.

5. Polymerization lossis Solrorification ntawm Ethyl Cellulose:

• Lub emulsified sib xyaw yog ces raug rau cov txheej txheem polymerization lossis salorification txheej txheem los ua cov kab mob ethulose polymer plhaub nyob ib ncig ntawm cov khoom tseem ceeb.
• Qhov no tuaj yeem ua tiav los ntawm cov kuab tshuaj evaporation, qhov chaw uas tsis yog cov khoom siv volaticy yog muab tshem tawm los ntawm emulsion, tawm hauv qab cov microcapsules.
• Hloov pauv, hla-txuas cov nom tswv lossis cov txheej txheem sib xyaws tuaj yeem ua haujlwm rau lub ethyl cellulose plhaub thiab ruaj khov cov microcapsules.

6. Ntxuav thiab ziab:

• Cov qauv tsim tau microcapsules tau ntxuav nrog cov kuab tshuaj uas haum lossis dej kom tshem tawm cov khoom siv tsis zoo lossis siv cov khoom siv.
• Tom qab ntxuav, lub microcapsules tau qhuav los tshem cov dej noo thiab xyuas kom ruaj khov thaum lub sijhawm cia thiab tuav.

7. Cwj Pwm thiab Tswjhwm Zoo:

• Lub Ethyl Cellulose microcapsules yog tus cwj pwm rau lawv qhov loj me, morphology, encapsulation kev ua hauj lwm zoo, thiab lwm yam khoom.
• Kev ntsuas zoo yog ua kom ntseeg tau tias cov microCapsules tau raws li cov kev xav tau zoo thiab kev ua tau zoo rau cov ntawv thov.

Xaus:

Cov txheej txheem npaj rau Ethyl nrho cellulose cuam tshuam nrog emulsification ntawm cov khoom siv tshuaj tiv thaiv corulose, ua raws li cov plhaub polymer kom encapsulate cov khoom tseem ceeb kom encapsulate cov khoom tseem ceeb. Ua tib zoo xaiv cov ntaub ntawv, emulsification cov tswv yim, thiab cov txheej txheem tsis zoo los ua kom tiav cov khoom siv uas xav tau rau ntau yam kev siv.
