nws daim ntawv thov ntawm ultrasonic homogenizer yog raws li nram no:
1. Rhuav tshem cov hlwb, cov kab mob, cov kab mob, cov noob kab mob, fungi, lossis cov ntaub so ntswg
2. Extraction ntawm cov khoom xyaw
3. Homogenization ntawm cov tshuaj ntawm txhua yam
4. Kev tsim cov tshuaj emulsions zoo tshaj plaws nrog cov kabmob me me ntawm qhov loj me
5. Kev zom cov roj-kom yaj thiab tsis tshua yaj-zom hauv cov dej
6. Ua khoom siv ntawm kev tawg thiab raug ncua
7. Catalysis thiab ua kom nrawm nrawm rau cov tshuaj lom neeg
Tsis tas li ntawd, tseem muaj ntau cov ntawv thov tshwj xeeb hauv chemistry, biology, thiab hauv ntau yam txuj ci kev kawm. Yog li ultrasonic homogenizers tau pom nce qhov tseem ceeb hauv kev tshawb fawb mob cancer rau kev npaj liposomes hauv xyoo tsis ntev los no. Tsis tas li cov homogenization ntawm kev tshem tawm ntawm tes hauv kev txiav txim siab kom cais tawm cov kab mob thiab tshem tawm cov protein los ntawm cov qauv tshwj xeeb yog cov piv txwv ntawm cov ntawv kho mob. Kev siv peev txheej muaj peev xwm yuav luag tsis paub kawg, txuas ntxiv ntawm kev tsim cov xim thiab xim xim siv ultrasonics, rau homogenization ntawm cov dej khib nyiab, kom tawg ntawm cov laum cores los ntawm cov av hauv lub hom phiaj rau kev tsom xam, thiab kev txiav txim siab ntawm qhov loj me me hauv kev soj Cov.
Hauv SONOCHEMISTRY, cov ntawv thov uas nrawm nrawm yog tshwj xeeb tshaj yog nthuav. Yog li, piv txwv li, cov tshuaj tiv thaiv reactivity ntawm cov hlau xws li lithium, magnesium, zinc, lossis txhuas tuaj yeem nce ntxiv los ntawm tshem cov txheej oxidized ntawm lawv cov chaw los ntawm kev sib kis ultrasonic. Ultrasonics kuj tseem muaj cov catalytic effect hauv cov tshuaj tiv thaiv ntawm hmoov. Lub catalytic hais tau zoo tsim los ntawm cavitation, uas ua rau muaj kev tawm tsam loj dua. Cov txiaj ntsig catalytic ntawm hmoov npib tsib xee, piv txwv, tau nce los ntawm qhov muaj txiaj ntsig ntau tshaj 100.000 thaum kho nrog ultrasonic vuam. Homogenizers kuj tseem siv tau los ua cov qauv hauv cov khoom xyaw ua ke, rau kev rhuav tshem cov saw hlau loj (depolymerization), thiab rau liquefaction ntawm cov xaim hlau hauv dej. Cov hluav taws xob tau nrawm nrawm thiab cua txias dhau ntawm" cavitation" hauv cov dej hauv lub cev los ntawm ultrasonics kuj pab txoj kev sib cais ntawm H2O rau hauv H+ reactive heev - thiab OH- - radicals. Tsis tas li" tawg" los ntawm alkanes (cov khoom tseem ceeb ntawm cov roj crude) rau hauv cov khoom me me uas xav tau (piv txwv li roj av), uas feem ntau tshwm sim ntawm qhov kub siab tshaj 500 ° C, yuav tshwm sim txawm nyob rau hauv chav sov thaum siv ultrasonics. Hauv chav kuaj ntawm German Red Cross hauv Berlin, kev tshawb pom tau ua uas cawm ntau lub sijhawm thiab ua haujlwm hauv kev sim paternity los ntawm kev siv ultrasonic homogenizers los npaj rau kev soj ntsuam dav dav. Nyob rau hauv no txoj kev, ib qho stroma-tsis muaj hemolysate, ib cov ntshav los daws teeb meem ntawm cov ntaub so ntswg ntawm tes raug tshem tawm, yog tsim tawm. Qhov kev daws teeb meem feem ntau yuav tsum tau ua los ntawm toluol ntawm 4 ° C rau tsawg kawg ib nrab ib teev thiab daim ntaub (= stroma) yuav tsum tau shaken tawm manually hauv toluol. Siv cov ultrasonic homogenizer, txawm li cas los xij, cov tshuaj daws ntshav tsuas yog pom nrog ultrasonics li ob peb lub vib nas this thiab cov qauv ntawm tes raug rhuav tshem. Cia thiab haking tawm yog tshem tawm, txo lub sijhawm npaj ntawm ntau dua 30 feeb txog 5 vib nas this. Qhov piv txwv ntxaws qhia txog qee qhov tseem ceeb ntawm kev siv tswv yim ntawm ultrasonic homogenizers. Qee yam tshuaj yeeb yaj kiab tuaj yeem xaiv tau rhuav tshem, cov sijhawm siv cov txheej txheem tuaj yeem yooj yim, cov txiaj ntsig ntawm ntau cov tshuaj tiv thaiv tau nce, thiab rov ua dua thiab siv cov tshiab uas tsis tau xav txog muaj tshwm sim. Kev tshawb nrhiav ultrasonic yog li ua pov thawj yog ib qho txaus nyiam teb uas rov ua dua rau tus kws tshawb fawb nrog cov txiaj ntsig xav tsis thoob. Yog li, piv txwv li, cov xov saw hlau ntev yuav tau tawg ua ke los ntawm ultrasonics yog tias lawv muaj lub cev qhov nyhav nyhav txaus. Tej yam macromolecules, txawm li cas los xij, yeej nce qhov loj me thiab qhov nyuaj yog tias lawv raug rau ultrasonics. Tus mob polio thiab lwm yam kab mob tsis hloov pauv mus rau sab nraud los ntawm sonic raug (piv txwv li lawv tsis tawg), tab sis kuj ceeb tias lawv tuaj yeem raug tua yooj yim nyob hauv txoj kev no. Thiab ib qho piv txwv ua tiav: Saccharomyces globulus, poov xab, ib txwm tsis muaj qhov cim tseg ntawm enzyme invertase uas sib cais sucrose Los ntawm kev siv ultrasonics, txawm li cas los xij, invertase tuaj yeem nrhiav pom sai sai (cov enzyme yog tej zaum nyob rau hauv daim ntawv tsis muaj zog thiab tau tsim los ntawm cov tshuaj sib npaug nrog Kev Lom Zem Zoo Nkauj lub pw tsaug zog). Hauv kev kaw, rau lub hom phiaj ntawm kev ua tiav ib daim ntawv thov sib txawv ntawm ultrasonic vuam yuav tsum tau hais: namely raws li kev pabcuam hauv kev ntxuav cov khoom ntawm txhua yam. Cov cavitation tau piav qhia saum toj saud kuj tso cov microcurrents hauv dej - sib" jetstreams" - whichare tuaj yeem tshem tawm txawm tias cov av tawv ncauj ntau tshaj plaws ntawm ib qhov chaw. Thiab vim tias cavitation tshwm sim txhua qhov chaw uas ultrasonic tsis ncav cuag hauv cov kua dej, txoj kev no yog qhov zoo tshaj plaws rau qhov kev ntxuav ntawm qhov muaj qhov tsis yooj yim, tsis zoo li cov cheebtsam uas yuav txwv tsis zoo lossis tsis nkag ntawm txhua qhov nkag tau xws li cov cuab yeej, li qub, nozzles, sib sau ua ke subassemblies, solder cov ntawv ntas, cov ntawv cog lus, thiab lwm yam.
