Ethyl cellulose microcapsule yokonzekera njira

Ethyl cellulose microcapsules ndi tinthu tating'onoting'ono kapena makapisozi okhala ndi chipolopolo chapakati, pomwe chophatikizira kapena katundu wolipidwa amatsekeredwa mkati mwa chipolopolo cha ethyl cellulose polima. Ma microcapsules awa amagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza mankhwala, chakudya, zodzoladzola, ndi ulimi, kuti atulutse molamulidwa kapena kubweretsa zinthu zomwe zasungidwa. Nayi chidule cha njira yokonzekera ma microcapsules a ethyl cellulose:

1. Kusankhidwa kwa Core Material:

• Zomwe zimayambira, zomwe zimadziwikanso kuti zomwe zimagwiritsidwa ntchito kapena zolipira, zimasankhidwa kutengera zomwe mukufuna ndikutulutsa.
• Itha kukhala yolimba, yamadzimadzi, kapena gasi, kutengera momwe ma microcapsules akufuna kugwiritsa ntchito.

2. Kukonzekera kwa Core Material:

• Ngati pachimake zakuthupi ndi olimba, pangafunike pansi kapena micronized kukwaniritsa kufunika tinthu kukula kugawa.
• Ngati pachimake zakuthupi ndi madzi, ayenera homogenized kapena omwazika mu abwino zosungunulira kapena chonyamulira njira.

3. Kukonzekera kwa Ethyl Cellulose Solution:

• Ethyl cellulose polima amasungunuka mu zosungunulira za organic, monga ethanol, ethyl acetate, kapena dichloromethane, kuti apange yankho.
• Kuchuluka kwa ethyl cellulose mu yankho kumatha kusiyanasiyana malinga ndi makulidwe omwe amafunidwa a chipolopolo cha polima komanso kutulutsa kwa ma microcapsules.

4. Njira ya Emulsification:

• The pachimake zinthu njira anawonjezera kuti ethyl mapadi njira, ndi osakaniza ndi emulsified kupanga mafuta-mu-madzi (O/W) emulsion.
• Emulsification chingapezeke ntchito makina mukubwadamuka, ultrasonication, kapena homogenization, amene akuswa pachimake zakuthupi njira ang'onoang'ono m'malovu omwazika mu ethyl mapadi njira.

5. Polymerization kapena Solidification wa Ethyl Cellulose:

• The emulsified osakaniza ndiye pansi polymerization kapena solidification ndondomeko kupanga ethyl mapadi polima chipolopolo kuzungulira pachimake zinthu m'malovu.
• Izi zitha kutheka chifukwa chosungunulira evaporation, pomwe chosungunulira cha organic chimachotsedwa mu emulsion, ndikusiya ma microcapsules olimba.
• Kapenanso, njira zolumikizirana kapena njira zolumikizira zingagwiritsidwe ntchito kulimbitsa chipolopolo cha ethyl cellulose ndikukhazikitsa ma microcapsules.

6. Kuchapa ndi Kuyanika:

• Ma microcapsules opangidwa amatsukidwa ndi zosungunulira zoyenera kapena madzi kuti achotse zonyansa zilizonse zotsalira kapena zinthu zosagwiritsidwa ntchito.
• Pambuyo kutsuka, ma microcapsules amawumitsidwa kuti achotse chinyezi ndikuwonetsetsa kukhazikika pakusungidwa ndi kusamalira.

7. Makhalidwe ndi Kuwongolera Ubwino:

• Ma microcapsules a ethyl cellulose amadziwika chifukwa cha kukula kwawo, morphology, encapsulation performance, kumasula kinetics, ndi zina.
• Mayesero owongolera khalidwe amachitidwa kuti awonetsetse kuti ma microcapsules akukwaniritsa zomwe mukufuna komanso njira zogwirira ntchito zomwe akufuna.

Pomaliza:

Kukonzekera kwa ethyl cellulose microcapsules kumaphatikizapo emulsification yazinthu zapakati mu njira ya ethyl cellulose, ndikutsatiridwa ndi polymerization kapena kulimba kwa chipolopolo cha polima kuti chitsekere zakuthupi. Kusankhidwa mosamala kwa zida, njira zama emulsification, ndi magawo azinthu ndikofunikira kuti mukwaniritse ma microcapsules ofananirako komanso okhazikika okhala ndi zomwe mukufuna pazogwiritsa ntchito zosiyanasiyana.

zonse.
