Dab tsi yog qhov zaus ntawm Ultrasonic emulsification?

Ultrasonic emulsificationyog ib txoj kev uas siv high-siv ultrasonic tsis yog siv los tsim ib tug nplua thiab ruaj khov emulsion. Qhov zaus ntawm ultrasonic emulsification yog ib qho tseem ceeb parameter uas txiav txim qhov loj ntawm cov tee dej thiab li no lub stability ntawm lub resulting emulsion.

Qhov zaus ntawm ultrasonic tsis siv rau emulsification feem ntau yog li ntawm 20 kHz mus rau ob peb megahertz. Feem ntau cov zaus siv rau emulsification yog nyob rau hauv thaj tsam ntawm 20 txog 40 kHz, uas yog suav tias yog tsawg zaus. Ntawm cov frequencies no, lub ultrasonic tsis tsim cavitation npuas nyob rau hauv cov kua, ua rau tsim thiab tawg ntawm me me tee dej.

Lub zog siab siv zog tsim los ntawm ultrasonic tsis ua rau muaj kev cuam tshuam ntawm kev sib tshuam ntawm cov kua dej tsis sib haum. Qhov no ua rau kev tsim cov tee me me uas me dua li cov uas tsim los ntawm cov txheej txheem ib txwm muaj xws li nplawm lossis homogenization.

Ultrasonic emulsification muaj ntau qhov zoo dua li cov txheej txheem ib txwm muaj. Qhov txiaj ntsig tseem ceeb tshaj plaws yog qhov ceev ntawm cov txheej txheem tuaj yeem ua tiav. Ultrasonic emulsification tuaj yeem tsim cov emulsion ruaj khov nrog qhov ntau thiab tsawg ntawm cov tee dej hauv thaj tsam ntawm 0.1 txog 10 μm hauv ob peb feeb xwb, uas yog nrawm dua li lwm txoj hauv kev.

Lwm qhov zoo ntawm ultrasonic emulsification yog tias nws yog ib qho yooj yim thiab tus nqi qis. Tsis zoo li lwm txoj hauv kev uas yuav tsum tau siv cov cuab yeej kim lossis kev cob qhia tshwj xeeb, ultrasonic emulsification tuaj yeem ua tiav siv qhov yooj yim ultrasonic sojntsuam lossis horn.

Cov ntawv thov ntawm ultrasonic emulsification muaj ntau thiab ntau yam. Nws yog feem ntau siv hauv kev lag luam zaub mov thiab dej haus los tsim cov emulsions ruaj khov ntawm cov roj thiab cov khoom xyaw dej. Nws kuj tseem siv rau hauv kev lag luam kws tshuaj los tsim cov tshuaj xa khoom nrog kev txhim kho bioavailability.

Hauv kev lag luam tshuaj pleev ib ce, ultrasonic emulsification yog siv los tsim cov emulsion ruaj khov rau cov tshuaj pleev, cream, thiab lwm yam khoom siv tawv nqaij. Hauv kev lag luam roj av, ultrasonic emulsification yog siv los tsim cov emulsions ruaj khov ntawm cov roj thiab dej kom txhim kho cov roj rov qab.

Hauv kev xaus, ultrasonic emulsification yog ib qho zoo heev thiab ntau yam txheej txheem rau tsim kom ruaj khov thiab zoo emulsions. Nws cov nqi qis, yooj yim, thiab nrawm ua rau nws yog ib txoj hauv kev zoo nkauj rau ntau yam kev siv, los ntawm kev ua zaub mov thiab dej haus rau cov roj rov qab thiab cov tshuaj xa mus.
