Cov nyhuv ntawm Ultrasonic zaus ntawm Deposition ceev

Lub zog nkhaus ntawm 40kHz thiab 60kHz ultrasound ntawm cov tshuaj deposition tus nqi ntawm lub ntiaj teb tsis tshua muaj ntau npaum li cas ntawm additives.

Nyob rau tib lub ntiaj teb tsis tshua muaj ntau npaum li cas, qhov tso tawm tus nqi qis dua 40kHz ultrasound siab dua qhov qis dua 60kHz. Raws li tus nqi ntawm lub ntiaj teb tsis tshua muaj cov ntsiab lus ntxiv, qhov sib txawv ntawm sedimentation tus nqi hloov pauv tsis pom tseeb, uas yog, nyob rau hauv qhov kev txiav txim ntawm ultrasound, qhov sib ntxiv ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb muaj kev cuam tshuam me me rau sedimentation tus nqi. Lub ntiaj teb tsis tshua muaj Ce muaj cov nqi hluav taws xob ntau thiab muaj peev xwm adsorption muaj zog, uas tuaj yeem txo cov haujlwm ntawm cov hlau ions xws li pob zeb diamond thiab npib tsib xee hauv cov tshuaj plating thiab ua rau kom muaj kev ruaj ntseg ntawm cov tshuaj plating. Cov kev sim hauv qab no tau ua los ntawm kev siv ultrasonic zaus ntawm 40kHz thiab lub suab siv ntawm 0.15W / cm'o

2.4 Cov nyhuv ntawm cov concentration ntawm cov ntsev tseem ceeb f ntawm sedimentation tus nqi

Lub zog nkhaus ntawm qhov loj concentration ntawm cov ntsev tseem ceeb ntawm cov tshuaj deposition tus nqi.

Cov ntsev tseem ceeb yog CoC12.6HZO thiab NiC12.6H20, nrog rau qhov sib piv loj ntawm 7: 3. Los ntawm daim duab, nws tuaj yeem pom tau tias cov sedimentation tus nqi tsawg heev thaum muaj cov ntsev ntsev tsawg dua, thiab nce sai nrog qhov nce ntawm cov ntsev loj concentration. Lub complexing neeg sawv cev tsim ib tug complex nrog hlau ions, uas txhawb lub dissociation equilibrium ntawm hlau ions raws li cov loj concentration ntawm lub ntsiab ntsev nce [3]. Yog li ntawd, thaum lub concentration ntawm cov ntsev tseem ceeb nce mus rau ib qho nqi, qhov deposition nqi yuav stabilize. Ntawm no, qhov siab tshaj plaws tshuaj deposition tus nqi tsis muaj ultrasound yog li ntawm 6mg / (cm '· h); Qhov siab tshaj plaws deposition npaum li cas nyob rau hauv ultrasonic tej yam kev mob yog hais txog 8mg / (cm '"h), uas txhais tau hais tias cov deposition tus nqi nce mus txog 30Yo. Nws tuaj yeem pom tau tias qhov zoo tshaj plaws rau COC12.6H, O, thiab NiC12.6H30 hauv ultrasonic tshuaj deposition yog 9.4 ^ -11.7g/L thiab 3.5-5.0g/L, feem.
