Dab tsi yog cov ntawv thov ntawm ultrasound hauv kev rho tawm ntawm cov khoom xyaw nquag hauv Suav tshuaj?
Cov cuab yeej siv tshuaj lom neeg ntawm cov tshuaj suav ib txwm muaj cuam tshuam ntau, thiab kev nthuav tawm ntawm nws cov khoom siv tau zoo yog cov ntsiab lus tseem ceeb hauv kev tshawb fawb ib txwm muaj. Cov tshuaj ua tau zoo ntawm cov tsoos suav tshuaj feem ntau hais txog cov tshuaj khes mis nrog cov qauv ntshiab hauv tshuaj lom neeg thiab cov teeb meem lub cev. Yog hais tias qhov concentration ntawm cov khoom xyaw zoo tsis siab, ntau npaum li cas yuav ua rau. Nyob rau tib lub sijhawm, lub hav zoov tsis muaj qhov muaj txiaj ntsig lossis qhov tsis zoo yuav ua rau cov tshuaj hauv Suav cov tshuaj yooj yim kom nqus dej noo. Nws muaj kev tsis txaus thiab tsis yooj yim khaws cia, yog li nws yog qhov yuav tsum tau muab rho tawm thiab cais cov khoom zoo ntawm Suav tshuaj. Ntau yam tshuaj lom neeg muaj txiaj ntsig hauv cov tshuaj hauv Suav yog cov tshuaj sib xyaw, uas yuav tsum tau tawg thaum rho tawm cov cell lossis cell cell. Txawm li cas los xij, nws yog feem ntau nyuaj rau cov txheej txheem tshuaj uas muaj tam sim no thiab kev siv tshuab txhawm rau txhawm rau rhuav cov hlwb kom ua tiav qhov kev tawg zoo tagnrho, uas cuam tshuam rau cov txiaj ntsig tawm.
Ultrasonic extraction tau qhia pom meej meej rau hauv kev rho tawm ntawm cov khoom siv tshuaj ntawm cov tshuaj suav ib txwm muaj vim nws qhov txawv txav mechanism thiab cov nyhuv extraction zoo tagnrho. Tshuab ultrasonic-pab tau siv lub zog kev co, lub nrawm nrawm, qhov ua tau zoo cavitation, thiab lub zog muaj zog ntawm ultrasonic kom luv lub sijhawm rau cov khoom xyaw zoo ntawm cov khoom ntuj tsim kom nkag mus rau qhov hnyav, ua kom cov txheej txheem rho tawm, nce tus nqi ntxiv, thiab ua haujlwm zoo kom tsis txhob muaj qhov kub thiab txias rau cov khoom xyaw zoo.
Xyoo tsis ntev los no, nrog kev tsim kho muaj zog ntawm kev tshawb nrhiav niaj hnub ntawm cov khoom siv ntuj tsim thiab cov thev naus laus zis ultrasonic, ntau tus kws tshawb fawb tau sib tham txog kev qhia txog kev siv tshuab mus rau hauv cov txheej txheem ntawm kev rho tawm cov khoom xyaw nquag, ib qho tseem ceeb ntawm kev tsim cov khoom ntuj.
Nyiaj txiag
Hauv cov khoom tsim cov txheej txheem rho tawm, txheej txheem ntawm phab ntsa tau tawg thiab lub ntsiab lus ntawm tes tau muab rho tawm tau yooj yim thiab ceev nrooj. Txij li thawj lub cim hluav taws xob ultrasound xyoo 1830, nws tau siv dav hauv ntau lub teb, xws li khoom noj khoom haus, kev kho mob thiab kev noj qab haus huv, thiab khoom siv hauv tsev. Nws yog manifested nyob rau hauv ultrasonic rho tawm, ultrasonic kom qhuav, ultrasonic kom tsis muaj menyuam, pom ultrasonic, ntxuav ultrasonic thiab lwm yam. Ntawm lawv, cov txheej txheem ultrasonic rho tawm kev siv cavitation, kev siv tshuab, thiab thermal cuam tshuam ntawm ultrasonic tsis ntxiv cov zaus thiab nrawm ntawm kev txav ntawm cov khoom siv molecules, nce kev nkag mus ntawm cov kuab tshuaj, thiab txhim kho kev qiv ntawm lub hom phiaj.
Nws muaj qhov zoo ntawm lub sijhawm-txuag, lub zog-txuag, thiab lub zog rho tawm ua haujlwm. Nws yog ib txoj kev nrawm thiab ua haujlwm tshiab hauv kev rho tawm, thiab tsis muaj txheej txheem ntawm cov cua kub hauv qhov kev rho tawm, uas tuaj yeem zam qhov kev hloov pauv ntawm cov qauv ntawm cov txheej txheem tshuaj los ntawm cua sov yam, thiab tuaj yeem siv rau kev rho tawm ntawm cov khoom cua sov. Ultrasonic rho tawm tau siv dav hauv kev coj ua rau kev soj ntsuam zoo ntawm tsoos suav tshuaj.
Nyob rau hauv xyoo tas los, nws daim ntawv thov hauv cov txheej txheem rho tawm ntawm cov tshuaj Hmoob ib txwm npaj tau kuj tau nyiam ntau dua thiab ntau, thiab qhov tseem ceeb tau ua tiav. Cov yoj ultrasonic siv nyob rau hauv cov kev rho tawm ntawm cov qauv ntoo yog feem ntau tsim los ntawm cov khoom siv sib nqus los ntawm lub zog hloov pauv. Kev siv tau nquag yog feem ntau nyob hauv thaj tsam ntawm 20-50kHz. Nws yog dav ntseeg tias nws cavitation, thermal thiab txhua yam teebmeem yog cov thev naus laus zis technology hauv kev rho tawm ntawm tsoos suav tshuaj. Peb lub hauv paus ntsiab lus.
