Taw qhia rau emulsification txoj kev
Nyob rau hauv xyoo tsis ntev los no, lub emulsification tau txais kev saib xyuas tseem ceeb thoob plaws ntau yam lag luam, suav nrog cov tshuaj, tshuaj pleev, khoom noj khoom haus. Emulsions yog colloidal tov nrog immiscible kua xws li roj thiab dej uas yog ruaj khov rau hauv homogeneous daim ntawv. Ntau txoj hauv kev ua haujlwm kom ua tiav emulsification, nrogUltrasonic EmulsificationTawm los ua cov txheej txheem cog lus.
Cov tswv yim emulsification ib txwm Txheej txheem cej luam
Tsoos Emulsification kev ntseeg rau lub cev sib xyaw thiab cov tshuab siv tshuab txhais tau tias, rotor mixers, thiab siab - lub siab homogenizers. Cov hau kev no tau ua qauv kev lag luam rau xyoo, vim lawv lub peev xwm ua kom muaj emulsions ruaj khov nrog qhov chaw zoo. Txawm li cas los xij, lawv feem ntau xav tau cov tswv yim tseem ceeb thiab cov tshuaj ntxiv ntawm cov tshuaj emulsifiers, uas tsis yog ib txwm yog vim ib puag ncig thiab kev noj qab haus huv.
Cov qauv hluav taws xob ultrasonic emulsifications
Ultrasonic emulsification siv cov siab siab - zaus suab tsis tsim kom muaj microlotculence hnyav nyob rau hauv nruab nrab ua kua. Tus txheej txheem no, hu ua acoustic cavitation, ua rau kev tsim cov microbubbles uas ua rau muaj kev sib tsoo thiab cov dav hlau ua kua uas tawg cov theem dispected rau hauv cov tee dej zoo.
Lub luag haujlwm ntawm cavitation thiab roj npuas
Lub hauv paus ntsiab lus ntawm cavitation plays lub luag hauj lwm tseem ceeb hauv ultrasonic emulsification los ntawm kev tsim cov siab shear rog thiab cua hlob. Lub xub ntiag ntawm cov roj npuas yog ib qho tshwj xeeb hauv hom no, pab txhawb kom me thiab muaj cov khoom ruaj khov me me vim lawv cov nqaij ntxig oscillations. Kev tshawb fawb qhia tau tias nce cov ntsiab lus roj txhim kho cavitation, ua rau txhim kho emulsification efficiency.
Kev sib piv ntawm droplet loj thiab ruaj khov
Droplet loj thiab ruaj khov yog qhov tsis tseem ceeb hauv kev ntsuas cov tswv yim emulsificate. Cov txheej txheem ib txwm muaj peev xwm tsim cov tee nrog qhov nruab nrab loj ntawm 1 txog 10 micrometers. Nyob rau hauv sib piv, ultrasonic emulsification tuaj yeem tsim cov tee dej me me li 100 nanometers, nyob ntawm seb cov xwm txheej zoo li ntau yam thiab kev siv fais fab. Qhov me me no droplet loj yog txuam nrog kev ruaj ntseg nce ntxiv, txo txoj kev pheej hmoo ntawm theem sib cais dhau sijhawm.
Cov txheej txheem ntawm emulsion stability
Qhov ruaj khov ntawm emulsification tsim ntawm ultrasonic emulsification feem ntau yog ntaus nqi rau cov steeler thiab electrostatic repulsions ntawm lub droplet interface. Tsis zoo li cov txheej txheem ib txwm, uas feem ntau vam khom tshuaj stabilizers, ultrasonic emulsification yuav ua tiav kev ruaj khov los ntawm lub cev rog. Qhov sib ntxiv ntawm cov xwm txheej ntuj xws li polysaccharides tuaj yeem txhim kho kom ruaj khov ntxiv, muab cov kev daws teeb meem ntau ib puag ncig.
Kev Noj Qab Haus Huv Ib Cheeb Tsam thiab Kev Noj Qab Haus Huv
Cov kev ua pov thawj emulsification feem ntau yuav tsum siv tshuaj chivilizers tshuaj lom neeg, uas yuav ua rau ib puag ncig thiab kev pheej hmoo. Cov tshuaj no tuaj yeem ua rau ib puag ncig, ua rau ntev ntev - TERVICATION kev puas tsuaj. Nyob rau hauv sib piv, ultrasonic emulsification txo lossis tshem tawm qhov xav tau rau cov stabilizers zoo li no, muab lub tshuab nqus tsev ntxhua khaub ncaws, ua kom huv si, kom ua tau zoo dua. Qhov no ua kom haum nrog kev cog qoob loo rau eco - Cov txheej txheem phooj ywg hauv kev lag luam wholesale ntau lawm thiab kev tsim khoom lag luam.
Kev siv cov ntaub ntawv thiab kev ua tau zoo
Daim ntawv thov kev lag luam ntawm ultrasonic emulsification ntau cov haujlwm, suav nrog cov tshuaj ua haujlwm, qhov uas nws pab hauv cov kev tawg ntawm cov khoom xyaw nquag. Kev lag luam kom zoo nkauj kuj tseem muaj txiaj ntsig los ntawm txoj kev muaj peev xwm tsim cov qauv ruaj khov thiab xwm yeem. Ntxiv mus, ultrasonic emulsification ua rau muaj zog dua ua hluav taws xob piv rau cov qauv ib txwm muaj, muab cov nqi txuag rau cov teeb meem thiab cov chaw muag khoom ntev.
Kev siv thev naus laus zis thiab cov lus qhia yav tom ntej
Kev nce qib hauv ultrasonic emulsification thev naus laus zis txuas ntxiv ua rau nws muaj peev xwm hauv cov ntawv thov kev lag luam. Kev sib koom ua ke ntawm microfluidics nrog ultrasound nthuav tawm cov cib fim rau kev tswj kom meej meej ntawm cov txheej txheem emulsification. Tsis ntev los no kev tsim tawm tau qhia cov tshiab parmetating rau kev ntsuas cov kev txuag hluav taws xob, xws li Dμ0.6 / ev nplai, uas muab piv rau kev ua tau zoo thoob plaws.
Haus peb hwjMuab cov kev daws teeb meem
Ntawm Hanspire, peb muab cov kev txhim kho emulsificate tshiab ua kom haum kom tau raws li kev lag luam xav tau tshwj xeeb.
