Cov txheej txheem yooj yim ntawm cov yas electroplating rau hluav taws xob cua sov raj
Txhua txheej txheem ntawm electroplating tsim cov dej khib nyiab, xws li cov txheej txheem ntawm cov yas electroplating:
Kev tshem tawm cov roj, tshem tawm roj, hydrophilicity, roughening, neutralization, pre impregnation, catalysis, gelation, tshuaj nickel, hydrochloric acidification, pyrocopper (los yog npib tsib xee), sulfuric acid activation, tooj liab acid activation, ammonium persulfate activation, semi gloss nickel nickel, sealing npib tsib xee, sulfuric acid activation, chromium anhydride activation, hexavalent chromium plating (trivalent chromium plating), sealing, thiab tev. Muaj cov txheej txheem uas tuaj yeem siv rau cov txheej txheem variegated, xws li tooj liab blackening, phom, pearl nickel, thiab chromium hloov. Rau galvanized alloy substrates, muaj hauv qab tooj liab plating (cyanide tooj liab plating), Micro cyanide kub plating, cyanide silver plating, thiab methylsulfonic acid tin plating rau kev ua haujlwm electroplating; Cov txheej txheem ntawm zinc plating tuaj yeem muab faib ua cyanide zinc plating, zincate zinc plating, chloride zinc plating, sulfate zinc plating, zinc nickel alloy plating, thiab lwm yam. . Cov txheej txheem sib txawv raug xaiv, thiab cov phiaj xwm zoo thiab kho cov dej khib nyiab yuav tsum muaj cov kev hloov pauv sib xws; Ntau cov nroj tsuag electroplating tau hloov pauv hauv lawv cov txheej txheem kev ntsuam xyuas ib puag ncig, cov txheej txheem tsim khoom tiag tiag, thiab cov tshuaj siv tshuaj, tab sis cov dej phwj tuaj thiab cov phiaj xwm dej tsis hloov pauv, ua rau cov nqi nce ntxiv thiab txo cov txiaj ntsig ntawm kev kho dej khib nyiab.
(4) Cov nag lossis daus pH qhov tseem ceeb ntawm cov hlau hnyav sib txawv yog qhov sib txawv, thiab qee cov dej khib nyiab tsis tuaj yeem sib xyaw thiab nag los ua ke. Higher pH qhov tseem ceeb (alkaline) hlau ions yaj hloov. Siv cov tooj liab, npib tsib xee, chromium, zinc, thiab nyiaj ua piv txwv, qhov zoo tshaj pH tus nqi thiab ntau yam uas tuaj yeem ua tau raws li tus qauv tso tawm.
Hauv qee cov txheej txheem hlau electroplating, cov dej khib nyiab nws tus kheej muaj ob lossis ntau dua cov hlau hnyav, xws li tooj liab thiab tin hloov nickel, tin thiab cobalt hloov chromium, tin thiab npib tsib xee uas muaj phom xim, thiab tooj liab thiab zinc muaj tooj dag. Hom kev kho dej khib nyiab no yuav tsum tau txheeb xyuas thiab kho ua ntej yog tias tsim nyog.
