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 nke microcapsules.

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 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 Solidification nke 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 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 dị mma na-asa 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.
