Qhov zoo ntawm ultrasonic emulsification tshuab
Muaj ntau hom emulsifiers siv hauv kev lag luam. Hauv cov sijhawm sib txawv, cov khoom sib txawv siv txawv emulsifiers. Hauv qab no, kuv yuav qhia qhov zoo ntawm ultrasonic emulsifiers.
Txhim kho cov nyhuv emulsification ntawm cov emulsifier
Raws li qhov poob ntawm qhov loj me ntawm qhov sib txawv theem, lub emulsion tuaj yeem muab faib ua microemulsion (10-100 nm), nanoemulsion (100-1000 nm) thiab emulsion loj (0.5-100μm). Ultrasound yog ib txoj hauv kev zoo los txo qhov me me ntawm qhov me me ntawm kev sib faib thiab emulsions. Cov khoom siv ultrasonic emulsification tuaj yeem tau emulsions nrog cov khoom me me me (tsuas yog 0.2-2μm) thiab nqaim droplet loj faib (0.1-10μm). Kev siv cov emulsifiers tseem tuaj yeem nce cov emulsion siab los ntawm 30% rau 70%.
Txhim kho emulsion ruaj khov
Hauv cov ntsiab lus, emulsions yog kev ua tsis ruaj khov, tsis txhob ua nthawv, thiab yog tias lawv txoj kev nyob ruaj khov tsis tswj hwm, lawv yuav cais mus rau lawv cov ntu sib nrug. Yog li no, txhawm rau ua kom cov kua dej tsim tawm tshiab ntawm cov theem dispersed kom tiv thaiv coalescence, emulsifiers thiab stabilizers ntxiv rau emulsion. Ultrasonic emulsification tsuas xav siv me me lossis tsis muaj emulsifier kom tau txais emulsion ruaj khov. Tom qab sonication, lub emulsion yuav nyob ruaj khov rau ntau lub hlis lossis ntau dua li ib nrab xyoo.
Tswj hom emulsion
Hauv qee qhov xwm txheej, ob hom emulsions," dej-hauv-roj" thiab" roj-hauv-dej" tuaj yeem tsim los ntawm ultrasonic technology. Cov qauv emulsification ib txwm tuaj yeem tswj cov khoom ntawm emulsion los ntawm kev ntxiv emulsifiers, thiab hom emulsion tsis tuaj yeem hloov los ntawm kev siv tshuab ib leeg. Cov khoom siv ultrasonic emulsification ua rau cov txheej txheem emulsification yooj yim dua thiab yoog raws.
Tsawg zog siv ntawm emulsifier
Lub zog noj ntawm phacoemulsification yog me me, thiab lub zog siv zog uas yuav tsum tau tsim tib lub ntim ntawm emulsion tsawg dua li ntawm qhov siab ntawm homogenizer. Los tsim cov emulsion uas muaj peev xwm ntawm 4.55 m3 / h thiab dej ntws ntawm 1μm hauv qhov loj me, yog siv ultrasonic emulsification siv, tsuas yog 57 HP ntawm kev quab yuam siv zog ntawm qhov ua haujlwm siab ntawm 10.514.1kg / cm2, tab sis kev ua haujlwm siab homogenizer yog ntawm 70.3351.6kg Raws li qhov ua haujlwm siab ntawm / cm2, 4050 HP yog qhov yuav tsum tau ua, yog li kev siv phacoemulsification technology tuaj yeem txo lub zog siv ntau.
Txhim kho txoj kev ua haujlwm emulsification
Ultrasonic emulsification tuaj yeem tsim cov emulsions uas tsis tuaj yeem tsim los ntawm cov qauv emulsification dav dav. Raws li lub zog ntom ntom zuj zus, qhov ntws los yuav tsawg zuj zus. Raws li qib tsim nyog ntawm lub zog ceev, phacoemulsification technology tuaj yeem ua tiav qhov nruab nrab qhov poob qis ntawm tsawg dua 1μm. Ultrasound txhawb nqa tag nrho cov txheej txheem emulsification kom tau nrawm dua thiab cov kev coj huv ntawm cov emulsion ua ntau dua.
Altrasonic yog lub tuam txhab uas tshwj xeeb hauv kev tsim emulsifiers. Txij li kev muag khoom ua ntej rau tom qab-muag, nws tau teeb tsa ib qho kev pabcuam ua tiav. Txawm hais tias nws yog lub tshuab nqus emulsifier, kua ntxuav ntxhua lauj kaub, ntim tshuab, thiab lwm yam, peb yuav pab cov neeg siv khoom ua ntej muag Qhov chaw tsim qauv, xaiv cov khoom siv, thiab ib qho kev pab txhawb nqa tau muab. Tau yeej kev qhuas zoo tshaj plaws los ntawm cov qhua tuaj noj mov.
