Dab tsi yog Ultrasonic Degassing?

Ultrasonic degassing qhov tseem ceeb siv "cov nyhuv cavitation" tsim thaum ultrasound nthwv dej tawm los ntawm cov kua rau strip, sib sau ua ke, thiab tshem tawm cov pa roj tawm ntawm cov kua. Nws cov txheej txheem tseem ceeb tuaj yeem muab faib ua peb theem tseem ceeb:

 

Thawj theem yog tsim cov npuas cavitation. Thaum ultrasound nthwv dej (feem ntau ntawm 20kHz thiab 1MHz) ua rau cov kua, cov kua molecules vibrate hnyav nyob rau hauv lub sij hawm hloov siab ntawm lub suab tsis. Nyob rau theem tsis zoo ntawm lub suab tsis zoo, cov pores me me hauv cov kua (xws li pawg ntawm cov pa roj molecules los yog qhov khoob ntawm qhov chaw me me impurities) nthuav dav sai, tsim ntau cov npuas me me, lossis "cavitation npuas." Nyob rau theem zoo siab, cov cavitation npuas no tau nrawm nrawm.

 

Qhov thib ob theem yog kev loj hlob thiab kev sib koom ua ke ntawm npuas. Nyob rau hauv qhov kev txiav txim tas mus li ntawm ultrasound tsis, cavitation npuas txuas ntxiv nqus cov pa yaj los ntawm cov kua ib puag ncig. Ib txhij, cov npuas me me uas nyob ib sab sib tsoo thiab sib koom ua ke nyob rau hauv kev tsav ntawm lub suab nthwv dej, maj mam tsim cov npuas loj. Thaum cov txheej txheem no, cov roj yaj hauv cov kua tsis tu ncua hloov ntawm cov kua theem mus rau theem gaseous, paub txog kev hloov pauv ntawm "cov pa yaj" mus rau "cov pa dawb."

 

Qhov thib peb theem yog qhov nce thiab tshem tawm ntawm npuas. Raws li cov npuas ntim nce, nws cov buoyancy maj mam dhau qhov viscous tsis kam ntawm cov kua, ua rau cov npuas nce sai heev rau cov kua nto, nws thiaj li tawg thiab tso nws cov pa hauv tsev, yog li ua tiav cov txheej txheem degassing. Tsis tas li ntawd, ultrasonic vibrations tuaj yeem ceev cov kua convection, ntxiv kev txhawb nqa npuas thiab sib sau ua ke, thiab txhim kho degassing efficiency.

Daim ntawv thov tseem ceeb ntawm ultrasonic degassing tshuab

 

1. Kev lag luam Electronics thiab Semiconductor

Nyob rau hauv semiconductor nti manufacturing thiab LCD vaj huam sib luag tsim, me me npuas npuas nyob rau hauv cov tshuaj tseem ceeb xws li photoresist, etching tov, thiab tus tsim tawm tuaj yeem ua rau muaj qhov tsis xws luag hauv cov qauv photolithographic thiab tsis sib xws, cuam tshuam rau cov khoom lag luam. Ultrasonic degassing tuaj yeem tshem tawm cov pa yaj thiab cov npuas huab cua los ntawm cov tshuaj no ntawm chav tsev kub, kom ntseeg tau qhov tseeb ntawm photolithography thiab etching txheej txheem. Tsis tas li ntawd, hauv kev tu cov khoom siv hluav taws xob, ultrasonic degassing txhim khu kev nkag mus ntawm kev ntxuav cov kev daws teeb meem, tiv thaiv huab cua npuas los ntawm adhering rau cov khoom siv thiab cuam tshuam rau kev tu kom zoo.

2. Kev lag luam tshuaj thiab khoom siv

 

Hauv kev tsim cov coatings, inks, thiab adhesives, muaj huab cua npuas tuaj yeem ua rau muaj qhov tsis xws luag xws li pinholes, craters, thiab tsis txaus gloss tom qab txheej. Ultrasonic degassing tuaj yeem tshem tawm cov npuas hauv huab cua sai sai tom qab txheej txheej txheej, txhim kho qib thiab kev ua haujlwm ntawm cov txheej. Hauv kev sib xyaw ntawm cov khoom siv polymer, cov roj yaj hauv cov monomers lossis cov tshuab polymerization tuaj yeem ua rau cov pores hauv cov polymer, cuam tshuam rau cov khoom siv tshuab; ultrasonic degassing zoo zam qhov teeb meem no. Tsis tas li ntawd, nyob rau hauv kev tsim thiab siv cov roj lubricating thiab hydraulic roj, ultrasonic degassing tuaj yeem tshem tawm cov huab cua los ntawm cov roj, tiv thaiv oxidation thiab deterioration, thiab txo cov khoom hnav thiab malfunctions.

3. Kev lag luam zaub mov thiab dej haus

Hauv kev tsim cov kua txiv hmab txiv ntoo, npias, dej haus carbonated (degassing theem), thiab cov khoom noj siv mis, cov roj yaj tuaj yeem ua rau cov khoom oxidation thiab deterioration, uas ua rau cov saj tsis zoo, los yog npuas dej thaum lub sij hawm bottling. Ultrasonic degassing tuaj yeem tshem tawm cov pa oxygen, carbon dioxide, thiab lwm yam gases los ntawm cov kua hauv chav tsev kub, ncua cov khoom txee lub neej thiab txhim kho saj stability. Piv txwv li, nyob rau hauv cov kua txiv hmab txiv ntoo concentration txheej txheem, degassing tuaj yeem tiv thaiv kom tsis txhob muaj xim tsis zoo thiab hloov tsw vim oxidation; nyob rau hauv ua ntej - pom theem ntawm npias ntau lawm, degassing tuaj yeem txhim kho pom kev ua haujlwm zoo thiab ua kom pom tseeb meej.

4. Kev lag luam Biopharmaceutical thiab Cosmetic

Cov ntaub ntawv xws li tshuaj lom neeg (xws li, tshuaj tiv thaiv, tshuaj tiv thaiv kab mob, kev npaj enzyme), tshuaj suav tshuaj suav tshuaj, thiab tshuaj pleev ib ce (xws li, ntsej muag cream, serums) feem ntau yog cua sov-rhiab heev thiab yooj yim oxidized, ua rau cov tshuaj degassing ib txwm nyuaj rau hloov. Ultrasonic degassing tuaj yeem tshem tawm cov roj tau zoo nyob rau hauv qis - kub, tshuaj lom neeg -dawb tej yam kev mob, tiv thaiv cov khoom denaturation thiab ua kom cov khoom ua haujlwm lom thiab ua tau zoo. Piv txwv li, hauv kev tsim tshuaj tiv thaiv, degassing tiv thaiv huab cua npuas los ntawm kev cuam tshuam rau qhov raug thiab ruaj khov ntawm kev xa tshuaj tiv thaiv; nyob rau hauv cov tshuaj pleev ib ce ntau lawm, degassing zam foaming thaum lub sij hawm siv cov khoom, txhim kho cov neeg siv kev paub.

5. Chaw kuaj thiab tshawb fawb teb

Hauv kev sim tshuaj thiab tshuaj lom neeg, cov roj yaj hauv cov tshuaj tiv thaiv tuaj yeem cuam tshuam cov txheej txheem tshuaj tiv thaiv thiab cuam tshuam rau qhov tseeb ntawm qhov kev sim. Ultrasonic degassing, raws li ib txoj kev sai thiab maj mam degassing, yog dav siv nyob rau hauv lub pretreatment ntawm kev sim kev daws teeb meem, xws li degassing chromatographic soj ntsuam kuaj thiab degassing electrolytes nyob rau hauv electrochemical thwmsim, kom ntseeg tau qhov kev ntseeg ntawm cov ntaub ntawv sim.
