Ethyl cellulose microcapsule nkwadebe usoro

Ethyl cellulose microcapsules bụ microscopic ụmụ irighiri ihe ma ọ bụ capsules nwere nhazi isi-shell, ebe a na-etinye ihe na-arụ ọrụ ma ọ bụ ụgwọ ọrụ n'ime shei polymer ethyl cellulose. A na-eji microcapsules ndị a na ụlọ ọrụ dị iche iche, gụnyere ọgwụ, nri, ịchọ mma, na ọrụ ugbo, maka ntọhapụ a na-achịkwa ma ọ bụ ebufe ebumnobi nke ihe mkpuchi. Nke a bụ nkọwa zuru ezu nke usoro nkwadebe maka microcapsules ethyl cellulose:

1. Nhọrọ nke isi ihe:

• A na-ahọrọ ihe bụ isi, nke a makwaara dị ka ihe na-arụ ọrụ ma ọ bụ ụgwọ ọrụ, dabere na ngwa a chọrọ na njirimara ntọhapụ.
• Ọ nwere ike ịbụ ihe siri ike, mmiri mmiri, ma ọ bụ gas, dabere na ebumnuche ejiri microcapsules mee ihe.

2. Nkwadebe nke isi ihe:

• Ọ bụrụ na isi ihe bụ ihe siri ike, ọ nwere ike ịdị mkpa ka ọ bụrụ ala ma ọ bụ micronized iji nweta nkesa nha nha nke achọrọ.
• Ọ bụrụ na ihe bụ isi bụ mmiri mmiri, ọ ga-abụ homogenized ma ọ bụ gbasasịa na ihe mgbaze kwesịrị ekwesị ma ọ bụ ihe na-ebu ibu.

3. Nkwadebe nke ngwọta ethyl cellulose:

• Ethyl cellulose polymer na-agbaze n'ime ihe mgbaze organic na-agbanwe agbanwe, dị ka ethanol, ethyl acetate, ma ọ bụ dichloromethane, iji mepụta ngwọta.
• Ntinye uche nke ethyl cellulose na ngwọta nwere ike ịdịgasị iche dabere na ọkpụrụkpụ nke shei polymer na ntọhapụ nke microcapsules.

4. Usoro emulsification:

• A na-agbakwunye ihe ngwọta isi ihe na ngwọta ethyl cellulose, na ngwakọta a na-eme ka emulsion na-emepụta mmanụ n'ime mmiri (O / W).
• Enwere ike nweta emulsification site na iji mkpasu iwe, ultrasonication, ma ọ bụ homogenization, nke na-agbaji isi ihe ngwọta n'ime obere ụmụ irighiri mmiri gbasasịrị na ngwọta ethyl cellulose.

5. Polymerization ma ọ bụ Mgbakwunye Ethyl Cellulose:

• A na-edobe ngwakọta emulsified na polymerization ma ọ bụ usoro siri ike iji mepụta shei polymer ethyl cellulose gburugburu isi ihe ụmụ irighiri mmiri.
• Enwere ike nweta nke a site na evaporation ihe mgbaze, ebe a na-ewepụ ihe mgbaze organic na-agbanwe agbanwe na emulsion, na-ahapụ microcapsules siri ike.
• N'aka nke ọzọ, enwere ike iji ihe ndị na-emekọrịta ihe ma ọ bụ usoro ịgbakọ coagulation iji mee ka shei ethyl cellulose sie ike ma mee ka microcapsules guzosie ike.

6. Ịsa na ihicha:

• A na-eji ihe mgbaze ma ọ bụ mmiri na-asacha microcapsules ndị a kpụrụ akpụ iji wepụ ihe ọ bụla na-adịghị mma ma ọ bụ ihe ndị na-emeghị eme.
• Mgbe ịsachara, microcapsules na-akpọnwụ iji wepụ mmiri mmiri ma hụ na nkwụsi ike n'oge nchekwa na njikwa.

7. Njiri mara na njikwa ogo:

• A na-eji microcapsules ethyl cellulose mara maka oke nkesa, morphology, arụmọrụ encapsulation, ntọhapụ kinetics, na ihe ndị ọzọ.
• A na-eme nyocha njikwa mma iji hụ na microcapsules na-emezu nkọwapụta achọrọ na njirisi arụmọrụ maka ngwa ezubere.

Mmechi:

Usoro nkwadebe maka ethyl cellulose microcapsules gụnyere emulsification nke isi ihe dị na ngwọta ethyl cellulose, na-esote polymerization ma ọ bụ ịkwado nke shei polymer iji kpuchie isi ihe. Nhọrọ nke ọma nke ihe, usoro emulsification, na usoro nhazi dị mkpa iji nweta microcapsules edo na nke kwụsiri ike na ihe ndị a chọrọ maka ngwa dị iche iche.
