Ntau cov khoom siv tu ultrasonic muaj degassing muaj nuj nqi, yog li dab tsi yog lub hauv paus ntsiab lus thiab kev ua haujlwm ntawm no degassing muaj nuj nqi?

Thaum ultrasound nkag mus rau hauv ib qho kev daws teeb meem, alternating siab yog generated. Thaum lub suab nthwv dej siv rau qhov pib cavitation propagates hauv cov kua, nws tuaj yeem tsim cov npuas cavitation thiab txhim kho qhov loj ntawm cov pa los ntawm kev daws rau cov npuas. Cavitation npuas yog tsim los ntawm me me roj nuclei nyob rau hauv cov tshuaj, thiab lawv yog generated nyob rau hauv lub sparse theem ntawm lub suab nthwv dej vim qhov kev txiav txim ntawm tensile kev nyuaj siab (tsis zoo siab). Yog hais tias tensile kev nyuaj siab tseem nyob tom qab tsim ntawm cavitation, lub cavitation npuas yuav nthuav mus rau ntau zaus nws pib loj. Nyob rau hauv cov ntaub ntawv no, lub cavitation npuas tuav ib tug spherical qauv thiab txuas ntxiv loj hlob, vibrate, thiab vau. Thaum siv ultrasound, cov khoom siv roj hauv cov tshuaj tuaj yeem "directionally diffuse" los ntawm cov roj-kua interface thiab nkag mus rau hauv cov npuas cavitation, uas nkag mus rau theem kev loj hlob. Thaum lub cavitation npuas tawg rau saum npoo ntawm cov tshuaj, cov pa roj yuav khiav tawm ntawm cov npuas, uas ua rau degassing.
Qhov zoo ntawm cov khoom siv ultrasonic degassing: ua npuas ncauj yog hais txog ntau cov npuas sib sau ua ke, thiab cov khoom siv ultrasonic degassing yog siv los defoaming thiab degassing cov kua nyob rau hauv thaum ntxov theem ntawm ua npuas ncauj tiam thiab ua ntej ib tug loj tus naj npawb ntawm npuas sib sau ua ke, los yog defoaming thiab degassing cov kua. gas yaj thiab tov rau hauv cov kua. Tag nrho cov txheej txheem tsis siv ib qho defoamer thiab yog ib txoj kev ua kom tiav lub cev defoaming, tseem hu ua mechanical defoaming method. Rau qhov tsim ua npuas ncauj, cov khoom siv tsis muaj qhov pom tseeb, uas yuav tsum tau daws ua ke nrog defoaming zaj duab xis.
Qhov tseem ceeb ntawm kev siv degassing yog "directional diffusion" ntawm ultrasound. Thaum cavitation tshwm sim, tseem muaj huab cua sab hauv. Hauv qee qhov molten kua degassing thiab purification daim ntaub ntawv, nws yog qhov zoo tshaj kom tsis txhob muaj cavitation. Cov huab cua ua kua yog tawm, txo qhov tsis kam ntawm npuas tsim los ntawm ultrasonic cavitation cov tshuaj tiv thaiv, thiab txhim khu kev tu efficiency ntawm lub tshuab ntxuav ultrasonic. Lwm qhov ua haujlwm yog tias lub tshuab ntxuav ultrasonic tuaj yeem ua kom muaj zog ultrasonic tom qab ua haujlwm ntev, txo cov nyhuv tu thiab ua haujlwm. Kev tshem tawm oxygen thiab degassing muaj nuj nqi kuj tuaj yeem tshem tawm qhov qaug zog ultrasonic.
Hauv cov ntsiab lus, nws tuaj yeem pom tias degassing muaj nuj nqi ntawm cov cuab yeej tu ultrasonic muaj zog heev, thiab ntau yam khoom hauv qab Gute Ultrasonic muaj degassing muaj nuj nqi, uas tuaj yeem ua tiav cov hom phiaj tu thiab txhim kho kev tu kom zoo.
