Electroplating ntshiab palladium electroplating
Ni tuaj yeem ua rau dermatitis, thiab EU tau ntev tsis lees txais cov khoom lag luam uas muaj Ni-muaj cov hniav nyiaj hniav kub. Palladium yog qhov zoo tshaj plaws hloov rau Ni. Txoj haujlwm no tau ua tiav hauv xyoo 1997, suav nrog ob txheej txheem, ib qho yog nyias palladium electroplating nrog lub thickness ntawm 0.1 ~ 0.2μm, uas tau siv los ua cov txheej txheem los tiv thaiv corrosion thiab anti-corrosion txheej. - nyiaj discoloration txheej ntawm cupronickel tin; lwm yam yog tuab palladium electroplating nrog lub thickness ntawm 3μm Tsis muaj kab nrib pleb (tam sim no thoob ntiaj teb theem), vim hais tias palladium yog kim, nws tseem tsis tau nkag mus rau hauv lub domestic kev ua lag luam.
Electroplating Tsis-Formaldehyde Autocatalytic Electroless Copper Plating
Rau kev hla-qhov plating thiab non-conductor nto metallization ntawm Circuit Court boards. Tshem tawm cov tshuaj lom formaldehyde thiab hloov nws nrog pheej yig thiab tsis muaj tshuaj lom hypophosphite. Tam sim no, tsis muaj cov khoom lag luam nyob hauv tsev thiab txawv teb chaws. Kev tshawb fawb hauv chaw soj nstuam tau ua tiav, tus nqi tso nyiaj yog 3 ~ 4μm / h, lub neej yog ntau tshaj 10 cycles (MTO), thiab cov txheej yog ntom thiab ci. Txawm li cas los xij, nws yuav tsum tau txhim kho ntxiv thiab sim hauv qhov kev sim ntsuas.
Electroplating cyanide-dawb autocatalytic electroless kub plating
Cov ntsev tseem ceeb yog Na3 [Au(SO3)2], thiab cov tuab ntawm txheej kub tuaj yeem ncav cuag 1.5μm, uas tau siv los ua kub plating ntawm high-density saj zawg zog Circuit Court boards thiab hluav taws xob ceramics.
Electroplating cyanide-dawb ci nyiaj plating
Hom hom siv thiosulfate ua tus neeg sawv cev tseem ceeb, thiab hom qib siab siv sulfur-free organics ua tus neeg sawv cev tseem ceeb. Lub thickness ntawm tag nrho cov ci txheej tuaj yeem ncav cuag ntau dua 40μm, qhov ua haujlwm ntawm cov txheej yog ~ 41μΩ·cm, hardness yog ~ HV101.4, thiab thermal shock yog tsim nyog ntawm 250 degree, uas yog ze rau qhov kev ua tau zoo. ntawm cyanide silver plating.
