Dent marks nyob rau hauv txheej ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov yeeb nkab
Qhov sib ntxiv ntawm surfactant txo qhov nro ntawm cov tshuaj electroplating, uas ua rau cov txheej txheem hydrogen evolution nrog cov txheej txheem cathodic electrodeposition. Cov dents, pits thiab pinholes ntawm txheej yog tiv thaiv, thiab lub zog sib txuas ntawm cov txheej thiab cov substrate yog qhov zoo.
Surfactant rau lub tshuab nqus tsev electroplating hluav taws xob cua sov raj
Surfactant yog ib yam khoom uas txo qhov nro ntawm cov kua hauv lub xeev, thiab tseem muaj cov khoom ntawm solubilization, emulsification, wetting, decontamination, sterilization, foaming, thiab lwm yam, thiab yog dav siv nyob rau hauv ntau yam teb. Surfactant yog ib qho tseem ceeb raw cov ntaub ntawv nyob rau hauv kev kho mob ntawm cov hlau nto, thiab nws kuj yog ib tug ntawm cov indispensable Cheebtsam ntawm feem ntau electroplating additives.
Nyob rau hauv tag nrho cov txheej txheem ntawm electroplating ua, xws li tshuaj degreasing ua ntej electroplating, pickling thiab xeb tshem tawm, electrolytic degreasing, matrix activation rau ib leeg hlau hauv electroplating, additives rau alloy electroplating, anti-coating discoloration tus neeg saib xyuas tom qab electroplating, txheej tiv thaiv Membrane thiab txawm electroplating. Kev kho dej khib nyiab, yuav luag txhua tus yuav tsum siv nws. Ntau hom kev siv tau txais txiaj ntsig los ntawm cov qauv tshuaj tshwj xeeb ntawm surfactants thiab yog li lawv cov khoom tshwj xeeb.
Roughness thiab burrs ntawm lub tshuab nqus tsev plating hluav taws xob cua sov raj
Tom qab ntawd nws yog ib qho tsim nyog yuav tsum tau tsom mus rau kev ntsuas pH tus nqi ntawm cov tshuaj ua kua, seb cov sludge nyob rau hauv lub hnab anode tshaj tus qauv, thiab tib lub sij hawm, xyuas cov dej zoo uas siv los saib seb cov calcium ion tshaj li tus qauv, thiab kuj. xyuas seb cov nickel ion hauv cov nickel sulfate siab dhau lawm. Roughness thiab burrs tuaj yeem tshwm sim yog tias nws tsis nyob hauv qhov tsim nyog
Kev tshem tawm ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov raj
Nyob rau hauv cov ntaub ntawv ntawm tev, ua ntej xyuas seb qhov kev kho mob ua ntej ntawm lub workpiece yog degreasing kiag li, seb puas muaj roj residue nyob rau hauv lub ces kaum tuag, thiab nyob rau tib lub sij hawm xyuas seb tus nqi pH ntawm cov tshuaj plating yog nyob rau hauv ib tug tsim nyog ntau yam. Nruab nrab ntawm grams ib liter, xyuas cov acid concentration ntawm pretreatment pickling, concentration ntawm hlau ions nyob rau hauv lub ntsiab plating tov, thiab tswj cov organic cov ntsiab lus thiab impurity cov ntsiab lus nyob rau hauv lub plating tov.
