Kedu akụrụngwa ultrasonic?

Ultrasonic akụrụngwa bụ elu - teknụzụ teknụzụ na-eji elu - ugboro ultrasonic iji nweta agwakọta nke mmiri. E jiri ya tụnyere usoro emulsification ọdịnala dị ka nke na-egbo mkpa na elu - nrụgide homogenization, ultrasonic nwere uru dị elu, na ezigbo emullification. Ọ bụrụla ngwa ọrụ dị mkpa n'ọhịa nri, ọgwụ, ihe ịchọ mma, na kemịkal.

Ulttasonic teknụzụ Emisic nke sitere na - narị afọ nke 20 ma nọgide na-etolite n'ọdịnihu nke teknụzụ ultrasonic. Ngwaọrụ Emulsiction ultrasonic nke ọgbara ọhụrụ etolitewo site na nyocha nke usoro mmepụta ihe, na-enwe ikike nhazi site na milileters n'ọtụtụ ụlọ ọrụ, na-ezute mkpa nke ụlọ ọrụ dị iche iche.

1. Core arụ ọrụ
Isi ihe eji arụ ọrụ nke akụrụngwa emulsics ultrasonic sitere na "cavitation acoustatic". Mgbe dị elu - ebili mmiri ultrasonic (ọ na-abụkarị na 20khz - a na-ebufe 100khz) na-ebugharị na mmiri mmiri, na-agbanwe dị elu - a na-etolite ebe nrụgide. Na ala - Nrụgide na-agba, obere anụ a na-emepụta na mmiri mmiri; Na elu - Nrụgide a, ụfụfụ ndị a na-akụda ngwa ngwa, na-ewepụta ọnọdụ okpomọkụ dị elu (ihe dị ka 5000K), nrụgide dị elu (ihe dị ka 1000atm) na ebili mmiri siri ike.

Mmetụta cavitation a na-eme ihe ike nwere ike:

Gbasaa agbada agbada
Na-akwalite mgbanwe ihe n'etiti oghere a
Wedata oke esemokwu
Melite nkwụsi ike emulsing

2. Ihe mejupụtara akụrụngwa
Usoro emulsifiction zuru oke na-agụnyekarị ihe ndị a na-esote:

Ultrasonic na-emepụta ihe: Na-agbanweta isi eletrik ka ọ dị elu - ugboro ugboro akara elektrọnik, na-agbanwe agbanwe na ike na ike
Mgbakọ transducer: Na-atụgharị ike eletriki n'ime usoro nke ọma, nke a na-ejikarị ihe eji eme nri cei
Amplifier (nyocha): na-atụpụta njupụta nke igwe kwụ ọtọ ma na-eme ihe na-agwọ ọrịa
Ngwunye ọgwụgwọ: Ezubere dika usoro usoro si dị, yana jaket dị jụụ
Usoro njikwa: Chọpụta usoro nrụpụta, usoro nlekota na ndekọ data

3.compared na teknụzụ emulsication ọdịnala, akụrụngwa emulsiction nwere ọtụtụ uru:

3.1. Ezigbo emulsification: nwere ike ịkwadebe emulsions na obere urughuru (ruo ọkwa nanosta) na nkesa dị warara, na ezigbo nkwụsi ike
3.2. Njikwa usoro: A na-enweta njikwa zuru oke site na idozigharị usoro dịka ike, ugboro na oge nhazi
3.3. Arụmọrụ ike dị elu: ike na-arụ ọrụ na usoro emulsification, mfu pere mpe, na-ebelata ike na 30 - 50%
3.4. Oge nhazi mkpụmkpụ mkpụmkpụ: na-abụkarị naanị nkeji ole na ole iji mezue usoro emulsig
3.5. Ngwa dịgasị iche iche: nwere ike ijikwa viscosity dị elu na sistemụ ọdịnaya siri ike, ma nwee omume enyi na-ewu ewu
3.6. Nhicha dị mfe na mmezi: Enweghị usoro arụ ọrụ siri ike, belata ihe ize ndụ mmetọ, ma na-ezute ihe ndị GMP
3.7. Enwere ike iji ya na teknụzụ ndị ọzọ: mfe ijikọ na microfluid, memplane emullification na teknụzụ ndị ọzọ na-etolite usoro
