Ethyl cellulose pokonzekera kukonzekera

Ethyl cellulose microboseles ndi tinthu ta microscopic kapena makapisozi okhala ndi chipolopolo chachikulu, pomwe chophatikizika chophatikizira kapena cholipidwa chimakhazikika mkati mwa ethyl cellulose. Izi zimagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo zamankhwala osiyanasiyana, chakudya, zodzoladzola, ndi ulimi, chifukwa chotulutsidwa kapena kuperekera katundu. Nayi mwachidule za njira yokonzekera ya Ethyl cellose sodi:

1. Kusankhidwa kwa zinthu zakunja:

• Zinthu zodziwika bwino, zimadziwikanso kuti ndizophika kapena kulipira ndalama, zimasankhidwa kutengera zomwe mukufuna komanso kumasulidwa.
• Itha kukhala yolimba, yamadzimadzi, kapena gasi, kutengera kugwiritsa ntchito ma microbopsules.

2. Kukonzekera kwa zinthu zoyambira:

• Ngati zinthu zolimba ndi zolimba, zingafunike kukhala pansi kapena kusamala kuti mukwaniritse gawo lomwe lingafunikire kukula kwa tinthu tambiri.
• Ngati zinthu zomwe zili pachimake ndi madzi, iyenera kukhala yovuta kapena yomwazika mu solvent yoyenerera kapena yankho lovomerezeka.

3. Kukonzekera kwa Ethyl cellulose yankho:

• Ethyl cellulose polymer imasungunuka m'malo osasunthika, monga ethanol, ethyl acetate, kapena dichloromethane, kuti apange yankho.
• Kukhazikika kwa ethyl cellulose mu yankho kumatha kusiyanasiyana kutengera kukula kwa chipolopolo cha polymer ndi mawonekedwe omasulira microcapsules.

4.. Kuchita Zinthu:

• Njira yothetsera matendawa imawonjezeredwa ku ethyl cellulose yankho, ndipo osakaniza amaphatikizidwa kuti apange mafuta am'madzi (o / w) emulsion.
• Emulsization imatha kugwiritsidwa ntchito pogwiritsa ntchito magetsi kusokonekera, ma ultrasonication, kapena homogenization, yomwe imaphwanya njira yothetsera matupi ang'onoang'ono m'mphepete mwa ethyl cellulose.

5. Polymerization kapena kulimbikitsa kwa ethyl cellulose:

• Kusakaniza kosakanikirana kumaperekedwa ndi polymerization kapena njira yolimbikitsira kuti apange ethyl cellulose polymese shell mozungulira malovu akuthupi.
• Izi zitha kuchitika kudzera mu sosurvent evicnuration, pomwe osasunthika osungunuka amachotsedwa kuchokera ku emulsion, kusiya microvoapsules.
• Kapenanso, magwiridwe antchito olumikizirana kapena njira zolumikizira zolumikizira zikagwiritsidwe ntchito kulimbitsa chipolopolo cha ethyl ndikukhazikitsa microbopsules.

6. Kusamba ndi kuyanika:

• Microcapsu yopangidwa imatsukidwa ndi zosungunulira kapena madzi okwanira kuchotsa zosakhazikika kapena zinthu zosafunikira.
• Mukatsukidwa, microcapsules imawuma kuti ichotse chinyezi ndikutsimikiza kukhazikika nthawi yosungira ndikugwira.

7..

• Mafuta a Ethyl cellose amadziwika kuti amagawa, morphology, amasinthasintha, amatulutsa kinetics, ndi zina.
• Mayeso apadera owongolera amachitika kuti awonetsetse kuti ma microbapsules amakwaniritsa zomwe mukufuna kuchita komanso zomwe mukufuna kugwiritsa ntchito.

Pomaliza:

Kukonzekera njira ya ma ethyl cellose microboseles kumaphatikizapo kufalikira kwa zinthu zomwe zili mu ethyl cellulose yankho, kutsatiridwa ndi polymerization kapena kulimbikitsa kwa polymerization kapena kutsimikizira kwa polymer chipolopolo kuti chiziphatikiza zinthu. Kusankha mosamala zida, njira za emulsization, ndi magawo a ndondomeko ndiyofunikira kuti tikwaniritse ma yunifolomu komanso zokhazikika zokhazikika ndi zomwe mukufuna pazogwiritsa ntchito zosiyanasiyana.
