Ultrasonic homogenizer tshuab hauv kev lag luam tshuaj pleev ib ce

Ua ntej sawv ntawm ultrasonic thev naus laus zis, cov tshuaj pleev cov tshuaj pleev ib ce kev vam meej xws li high}} {}}} hom homogenizers rau homogenization. Thaum siab - hilling homogenizers tuaj yeem kho cov ntsiab lus rau qee qhov kev kub siab, siv cov teebmeem siab, cov teebmeem siab kom ua tiav homogenization. Txoj kev tawm tsam no los txo qhov nyuaj {}} pa tawm ntawm cov nroj tsuag thiab nqus ntawm cov khoom lag luam nquag. Piv txwv li, hauv zus tau tej cov tshuaj pleev ib ce muaj cov nroj tsuag tseem ceeb, muaj kev faib tawm dav dav. Ib qho me me ntawm cov microcapsules tsis yog cuam tshuam rau cov khoom zoo nkauj tab sis kuj tseem tuaj yeem ua rau nqus tsis haum los ntawm daim tawv nqaij, txo cov khoom lag luam tsis zoo.

Agitator -} Hom homogenizers feem ntau cia siab rau tsim kom muaj kev ntseeg siab thiab cov rog shear hauv lub thawv, ua tiav kev sib xyaw ua ke thiab homogenization. Txawm li cas los xij, cov qauv no ua rau muaj zog tiv thaiv shear, ua rau nws muaj txiaj ntsig zoo rau qhov siab- viscosity cov ntaub ntawv lossis cov tshuab yuav tsum tau ua tiav qib siab. Thaum npaj siab siab -}}}} Homogenizers tawm tsam rau tusyees cov khoom siv lub neej thiab cuam tshuam nws cov khoom ruaj khov. Tsis tas li ntawd, cov txheej txheem homogenization feem ntau ua haujlwm ntawm cov vitamins siab, uas tuaj yeem txo cov khoom xyaw kub, uas yog li tsis muaj zog ntawm kev ua kom zoo nkauj.

(I) cavitation nyhuv: "cov khoom tawg" ntawm lub ntiaj teb microscopic
Ib qho ntawm cov tub ntxhais secrets ntawm Ultrasonic homogenization lus dag nyob rau hauv cov cavitation nyhuv, uas yog qhov muaj zog "tawg" hauv ntiaj teb me me. Thaum lub tshuab hluav taws xob ultrasonic tsim cov siab- Cov suab nrov zoo li 15kHz, thiab 1MHz, thiab 1MHz, thiab 1MHz, "ua txuj ci tseem ceeb," ua yeeb yam txuj ci txawv hauv cov kua. Qhov kev sib txuas ntawm kev sib txuas thiab txuas ntxiv ntawm cov suab nrov, zoo li lub ntsej muag tsis pom, tsim ntau yam me me "Cavitation npuas" nyob rau hauv cov kua. Cov npuas no zoo li nquag "me me foob pob" muaj roj lossis vapor.

Raws li lub suab tsis txuas ntxiv, cov pa cavitation bubbles pib lawv luv luv tab sis khaus taug kev. " Thaum lub sijhawm txuas ntxiv, npuas nthuav dav zoo li cov pa zais pa; Thaum lub sij hawm compressress, lawv vau xws li cov zais pa dheev. Tag nrho cov txheej txheem tshwm sim nyob rau hauv tsuas yog micreeconds. Thaum lub sijhawm luv luv no ntawm lub sij hawm tsaus muag, cov txheej txheem huab heev tshwm sim nyob ib ncig ntawm cavitation npuas, zoo li me me "supororm." Cov chaw kub hauv zos tuaj yeem soar rau 5000k, kub tshaj li saum npoo ntawm lub hnub; Pressures tuaj yeem ncav cuag 100 MPA, sib npaug los tso ob peb tons ntawm qhov hnyav ntawm cov rau tes. Ib txhij, khaus microejets, mus txog nrawm txog li 100 m / s, zoo li kev tawm tsam ceev, thiab muaj zog} ceev cov mos txwv, mob ntshav, lossis cov hlwb tsis pub dhau cov khoom siv. Piv txwv li, thaum npaj nanoemulsions, cov kev mob siab no tuaj yeem ua li cas rau theem AGGROMERTE rau hauv cov khoom siv aqueous, tso lub hauv paus rau cov tshuaj pleev ib ce thiab nqus tau zoo.

(II) Txhua yam shear thiab cua hlob: syeroistic "masters ntawm kev sib xyaw"
Ntxiv rau cov cavitation nyhuv, tshuab shear thiab cua hlob kuj ua tau lub luag haujlwm tsis tseem ceeb hauv ultrasonic homogenization. Zoo li kev sib koom tes zoo ib yam "tus tswv ntawm kev sib xyaw," lawv ua haujlwm hauv tandem nrog cov cavitation cuam tshuam. Thaum ultrasound propagates los ntawm cov khoom siv, nws induces siab- kev co thiab pov tseg ntawm cov khoom siv cov lwg me. Qhov kev co thiab kev hloov hluav taws xob ua rau cov tshuab hluav taws xob hnyav. Cov neeg kho tshuab cov tshuab hluav taws xob ua zoo li ntse "piab," txiav thiab tawg cov khoom loj lossis maj mam txo lawv mus rau cov ntawv me me. Thaum ua cov ntaub ntawv pleev xim rau cov polymer loj, tshuab ntxiag rog tuaj yeem ua rau cov tawg loj, ua kom yooj yim rau tawg thiab sib tov.

Cua hlob, ntawm qhov tod tes, yog zoo li ib qho kev ntxhov siab tsis tau lees tias "seev cev," sib sau cov qauv ntws hauv cov khoom siv. Ultrasonic tsis muaj zog induce tsis xwm yeem thiab kho nyob rau hauv cov khoom siv. Cov cua hlob no ntws txhawb ntau dua thiab ua kom pom sib ze ntawm cov khoom sib txawv hauv cov khoom siv. Thaum ua semi- cov tshuaj pleev ib ce xws li cov tshuaj xyaw ua ke, tiv thaiv ntau yam kev hloov hauv cheeb tsam. Mechanical shear thiab tsiv ua haujlwm hauv tandem nrog cov cavitation nyhuv. Lub zog muaj zog muaj zog tsim los ntawm cavitation thaum tawg cia cov khoom loj, thiab cua tshuab ua kom cov khoom sib faib ntawm cov lus zoo thoob plaws thoob plaws hauv cov khoom siv. Peb yam peb yam ua kom tau ib leeg ua tiav txhua tus kom ua tiav cov khoom siv homogenized, muab lub hauv paus ruaj khov rau qhov siab {{}} Cov tshuaj pleev ib ce siab.

Kev tsim kho nruj ua lag luam hauv ultrasonic homogenization technology tseem yuav nqa cov qauv khoom tshiab thiab cov txiaj ntsig rau kev lag luam tshuaj pleev ib ce tshiab. Nrog rau hauv - qhov tob nrhiav rau hauv lub cev cov qauv thiab cov tshuaj pleev ib ce tuaj yeem tso cov tshuaj tua kab mob zoo dua thiab cov khoom siv ceev ceev. Ultrasonic homogenization thev naus laus zis muaj lub peev xwm kom ua tiav nanoscale encapsulation thiab tsom cov khoom xyaw tshwj xeeb, txhim kho kev ua kom zoo nkauj skincare? Tsim Nano {{{{4 4}}}}}}}}} Cov khoom puas uas tuaj yeem tsim kho cov khoom siv dawb, lossis cov khoom ntxuav hniav dawb uas tsis muaj kev nkag tau zoo me me, thiab lwm yam muaj peev xwm.
Los ntawm macro pom, qhov kev thov cuam tshuam ntawm ultrasonic homogenization kev lag luam yuav tsav lub tshuaj pleev ib ce kev lag luam rau ntsuab thiab muaj kev lag luam kom ruaj khov. Nws lub siab ua haujlwm, txuag hluav taws xob, thiab qis {{{-} kub ua raws li kev tiv thaiv thoob ntiaj teb no thiab kev txhim kho kom ruaj khov. Raws li cov thev naus laus zis tau ntau dua, ntau dua cov chaw pleev tshuaj Qhov no yuav tsis tsuas pab cov tuam txhab txo cov nqi thiab txhim kho lawv cov duab tseem ceeb, tab sis kuj tseem yuav muaj kev tsim kho tshiab ntawm cov tshuaj pleev ib ce kev lag luam txhua tus.
