Mokhoa oa ho lokisa ethyl cellulose microcapsule

Li-microcapsules tsa Ethyl cellulose ke likaroloana tse nyenyane kapa li-capsules tse nang le sebopeho sa khetla ea mantlha, moo motsoako o sebetsang kapa mojaro o lefang o kentsoeng ka har'a khetla ea ethyl cellulose polymer. Li-microcapsules tsena li sebelisoa liindastering tse fapaneng, ho kenyeletsoa meriana, lijo, litlolo le temo, bakeng sa tokollo e laoloang kapa phano e lebisitsoeng ea ntho e kentsoeng. Mona ke kakaretso e akaretsang ea ts'ebetso ea ho lokisa li-microcapsules tsa ethyl cellulose:

1. Khetho ea Lintho tsa Bohlokoa:

  • Lisebelisoa tsa mantlha, tse tsejoang hape e le motsoako o sebetsang kapa mojaro oa moputso, li khethoa ho ipapisitse le ts'ebeliso e lakatsehang le litšobotsi tsa tokollo.
  • E ka ba ntho e tiileng, e metsi, kapa ea khase, ho itšetlehile ka tšebeliso e reretsoeng ea microcapsules.

2. Tokisetso ea Lintho tsa Bohlokoa:

  • Haeba thepa ea mantlha e tiile, e ka 'na ea hloka ho siloa kapa ho etsoa micron ho finyella kabo ea boholo bo lakatsehang.
  • Haeba thepa ea mantlha ke mokelikeli, e lokela ho ba homogenized kapa e qhalakantsoeng ka tharollo e loketseng ea solvent kapa carrier.

3. Tokiso ea Tharollo ea Ethyl Cellulose:

  • Ethyl cellulose polymer e qhibiliha ka har'a mokelikeli o sa tsitsang oa lintho tse phelang, tse kang ethanol, ethyl acetate, kapa dichloromethane, ho etsa tharollo.
  • Khatello ea cellulose ea ethyl ka tharollo e ka fapana ho latela botenya bo lakatsehang ba khetla ea polymer le litšobotsi tsa tokollo ea li-microcapsules.

4. Mokhoa oa Emulsification:

  • Tharollo ea thepa ea mantlha e kenyelletsoa ka tharollo ea ethyl cellulose, 'me motsoako o etsoa emulsified ho etsa emulsion ea oli-ka-metsi (O/W).
  • Emulsification e ka finyelloa ka ho ferekanngoa ha mechine, ultrasonication, kapa homogenization, e senyang tharollo ea thepa ea mantlha ka marotholi a manyenyane a qhalakantsoeng ka tharollo ea ethyl cellulose.

5. Polymerization kapa Solidification ea Ethyl Cellulose:

  • Motsoako o entsoeng ka emulsified o kenngoa tšebetsong ea polymerization kapa solidification ho theha khetla ea ethyl cellulose polymer ho potoloha marotholi a mantlha.
  • Sena se ka finyelloa ka mouoane oa solvent, moo mokelikeli o tsitsitseng oa tlhaho o tlosoa ho emulsion, o siea ka morao li-microcapsules tse tiileng.
  • Ntle le moo, ho ka sebelisoa lisebelisoa tse hokahanyang kapa mekhoa ea ho kopanya ho tiisa khetla ea ethyl cellulose le ho tsitsisa li-microcapsules.

6. Ho Hlatsoa le ho Omisa:

  • Li-microcapsules tse entsoeng li hlatsuoa ka solvent e loketseng kapa metsi ho tlosa litšila leha e le life tse setseng kapa thepa e sa sebetsanoeng.
  • Kamora ho hlatsoa, ​​​​li-microcapsules li omisitsoe ho tlosa mongobo le ho netefatsa botsitso nakong ea ho boloka le ho sebetsana.

7. Sebopeho le Taolo ea Boleng:

  • Li-microcapsules tsa ethyl cellulose li khetholloa bakeng sa kabo ea boholo ba tsona, morphology, katleho ea encapsulation, kinetics ea tokollo, le thepa e meng.
  • Liteko tsa taolo ea boleng li etsoa ho netefatsa hore li-microcapsules li kopana le litlhaloso tse lakatsehang le litekanyetso tsa ts'ebetso bakeng sa ts'ebeliso e reriloeng.

Qetello:

Mokhoa oa ho lokisa li-microcapsules tsa ethyl cellulose o kenyelletsa emulsification ea thepa ea mantlha ka tharollo ea ethyl cellulose, e lateloa ke polymerization kapa ho tiisa khetla ea polymer ho koahela thepa ea mantlha. Khetho e hlokolosi ea lisebelisoa, mekhoa ea emulsification, le mekhahlelo ea ts'ebetso e bohlokoa ho fihlela li-microcapsules tse ts'oanang le tse tsitsitseng tse nang le thepa e lakatsehang bakeng sa lits'ebetso tse fapaneng.
