Ultrasonic kua emulsification khoom

Nqe lus piav qhia:

Nano-emulsions tuaj yeem siv tau hauv ntau daim ntawv thov thiab kev lag luam sib txawv. Kev muag tshuaj thiab kev xa tshuaj tuaj yeem hais tau tias yog ib qho tseem ceeb tshaj plaws uas nanoemulsions tau siv los ua nano-carriers kho ntau yam kab mob. Cov tshuaj tua kab mob, tshuaj tiv thaiv kab mob, thiab tshuaj tiv thaiv hypertensive yog cov tshuaj tsis ntev los no solubilized hauv nano-emulsions.

Tsis tas li ntawd, kev siv nanoemulsions hauv cov zaub mov thiab khoom noj khoom haus kev tshawb fawb thiab thev naus laus zis yog ib thaj chaw uas cov kws tshawb fawb tau ua haujlwm los tsim cov khoom noj khoom haus muaj kev ruaj ntseg, noj qab haus huv, thiab nyab xeeb dua. Nanoemulsion thev naus laus zis tshwj xeeb yog siv rau hauv cov zaub mov encapsulation thiab kev ua, cov txheej txheem khaws cia thiab kev tiv thaiv, nrog rau kev xa khoom rau ntau cov khoom siv bioactive lipophilic. Kev ua tau zoo thiab kev ua haujlwm ntawm cov nanoemulsions tau pom tias muaj txiaj ntsig ntau dua li cov pa emulsions thiab lawv tiv thaiv cov zaub mov degradation thiab txhim kho bioavailability.

Nanoemulsions kuj tau nce kev ua haujlwm hauv cov tshuaj pleev ib ce tshwj xeeb rau kev tswj xyuas kom zoo nkauj thiab cov khoom xyaw nquag rau cov tawv nqaij tshwj xeeb. Lawv feem ntau yog thermodynamically ruaj khov, pob tshab thiab muab kev tiv thaiv hydrolysis thiab oxidation. Vim yog qhov me me me me thiab nws qhov chaw siab, nanoemulsions muaj cov nyhuv bioactive uas tso cai rau nkag mus rau hauv daim tawv nqaij sai thiab muaj txiaj ntsig. Cov tshuaj pleev ib ce nanoemulsions feem ntau tsis pom cov sedimentation, coalescence lossis flocculation feem ntau qhia rau cov macroemulsions. Cov nanoemulsions siv hauv tshuaj pleev ib ce feem ntau xav tau lub zog qis thiab qis qis ntawm surfactant piv rau microemulsion.

Dej thiab roj, raws li ob lub kua dej nrog ntau daim ntawv thov, muaj cov khoom tshwj xeeb ntawm ib qho. Ntau dua vaporization kub, lubricity thiab durability nyob rau hauv cov roj thiab qis viscosity, xwm compatibility thiab muaj nyob rau hauv dej yog ib co ntawm cov laj thawj rau ncua kev siv ntawm cov kua. Muaj ntau lub lag luam uas siv dej thiab roj ib txhij; Txawm li cas los xij, tsim cov nano-emulsions lossis miniemulsions (xws li emulsions feem ntau nrog cov tee me me ntawm 50-500 nm, tsim los ntawm ob peb cov kua dej tsis zoo nrog cov khoom ruaj khov) tseem yog qhov nyuaj hauv ntau qhov kev lag luam. Txhawm rau tsim homogenous nano-emulsions, cov txheej txheem sib txawv, xws li txo cov roj theem concentration, siv cov khoom siv saum npoo av (surfactants), kev kub ceev stirring, thov kev kub siab, thiab cov txheej txheem ua ultrasonic tau tsim. Peb tsom ntsoov rau txoj kev kawg, piv txwv li cov txheej txheem ua ultrasonic.

Qee cov neeg tshawb nrhiav tau npaj lawv cov nanoemulsion los ntawm txoj kev ultrasonic emulsification thiab siv nws rau polymerization, encapsulation lossis crystallization. Qee qhov kev tshawb fawb tau siv cov emulsification hauv kev lag luam zaub mov, tshuaj thiab tshuaj pleev ib ce, biodiesel, atomization thiab ntxuav. Txoj kev emulsification tsis ntev los no tau ua haujlwm ua ib txoj hauv kev zoo tshaj plaws rau kev npaj homogenous nano-emulsions. ib qho ultrasonic transducer (piv txwv li qhov tseem ceeb ntawm lub tshuab ultrasonic) feem ntau yog ua los ntawm piezoelectric ceramics nruj los ntawm cov ntsia liaj qhov rooj ntawm lub nraub qaum (feem ntau yog ua los ntawm cov khoom siv hlau) thiab qhov sib txuam (feem ntau yog ua los ntawm titanium lossis aluminium alloy) yog siv. los tsim ultrasonic vibrations. Nyob rau hauv cov ntaub ntawv ua kua los yog ib nrab khoom, UPT tsim ib qho kev sib zog acoustic cavitation teb tawg, piv txwv li, kua / kua cuam tshuam ntawm cov roj-tej dej, ua kom yooj yim nanoemulsions npaj nrog me me me me me me me me me me me me me me (MDDS) thiab ntau ntau lub sijhawm ruaj khov.

Daim ntawv thov:

Phacoemulsification tau siv rau hauv ntau qhov chaw, thiab nws ua lub luag haujlwm tshwj xeeb hauv txhua qhov chaw.

Muaj ntau daim ntawv thov kev lag luam phacoemulsification. Ultrasonic emulsification yog ib qho ntawm cov thev naus laus zis tshaj plaws siv hauv kev ua zaub mov. Piv txwv li, cov dej qab zib, ketchup, mayonnaise, jam, mis nyuj, khoom noj rau menyuam yaus, chocolate, zaub xam lav, dej qab zib thiab lwm yam khoom siv sib xyaw siv hauv kev lag luam zaub mov tau raug sim thiab siv hauv tsev thiab txawv teb chaws, thiab txhim kho cov nyhuv ntawm cov khoom zoo thiab kev ua haujlwm zoo, thiab dej-carotene emulsification tau ua tiav kev sim thiab siv hauv kev tsim khoom.
