Ultrasound fais fab hauv Ultrasonic kua Dispersion

Qhov feem ntau mas thiab dav paub zoo ntawm fais fab ultrasound hauv dej yog cov nyhuv dispersing. Xws li phacoemulsification, ultrasonic pulverization, ultrasonic gel liquefaction, ultrasonic kua atomization thiab ultrasonic tu.

Ultrasound nyob rau hauv cov kua dispersion, txhua tus tub rau cov kua cavitation nyhuv. Txawm li cas los xij, cavitation yuav tsis tshwm sim yog tias qhov kev siv acoustic dua qis dua qhov cavitation valve los yog cavitation yog txhob txwm suppressed. Ultrasound dispersion hauv qhov kev ntsuam xyuas zaum kawg yog raws li "cavitation" ntawm qhov yooj yim mechanism.

Siv ultrasonic dispersion, emulsifiers tsis tas yuav siv, feem ntau qhov ultrasonic emulsification yuav 1μm hais hauv qab no. Tus tsim ntawm no zoo-emulsion yog feem ntau vim yog lub zog cavitation ntawm ultrasound ze lub cuab tam dispersive.

Ultrasonic dispersion ntawm kev siv:

Dispersion nrog ultrasonic tsis, emulsifiers tsis tas yuav siv ntau zaus, phacoemulsification yuav 1μm hais hauv qab no. Tus tsim ntawm no zoo-emulsion yog feem ntau vim yog lub zog cavitation ntawm ultrasound ze lub cuab tam dispersive.

Ultrasound dispersion nyob rau ntau qhov chaw muaj ntau hom kev siv: xws li zaub mov, tshuaj pleev ib ce, tshuaj, chemistry thiab lwm yam.

Ultrasound nyob rau hauv daim ntawv thov ntawm cov zaub mov dispersion yuav muab faib ua: kua - kua dispersion (emulsion), khoom - kua dispersion (raug tshem tawm), roj - kua dispersion ntawm peb tus neeg mob.

Ua kua - kua dispersion (emulsion): Yog hais tias butter yuav emulsified, ua los ntawm high lactose; sauce ntau lawm, lub dispersion ntawm raw cov ntaub ntawv.

Khoom - kua dispersion (suspension): xws li cov dispersion ntawm hmoov emulsion.

Gas-liquid dispersion: xws li cov khoom siv ua kua dej, CO2 txoj kev nqus tau zoo tuaj yeem tuaj yeem khees me ntsis ntxiv, kom zoo rau kev ruaj ntseg.
