Muaj ntau ntau hom kev daws teeb meem ntawm ib puag ncig tus phooj ywg electroplating; ntau tshaj kaum tau siv nyob rau hauv kev tsim kev sim. Plaub feem ntau siv plating kev daws teeb meem hauv kev tsim khoom yog cyanide zinc plating, zincate zinc plating, chloride zinc plating, thiab sulfate zinc plating. Txawm hais tias ntau yam kev daws teeb meem plating hloov zuj zus raws li qhov sib txawv ntawm cov ntsev tseem ceeb thiab lwm yam khoom, lawv yeej tseem zoo ib yam.
Cyanide Zinc Plating
Qhov zoo ntawm cyanide zinc plating: zoo siv lead ua qauv; zoo dispersion thiab npog lub zog, muaj zog ua kom muaj zog, thiab zoo heev tiv thaiv impurities; ua ib tug bluish-dawb passivation zaj duab xis tom qab kev kho mob passivation; tuav zoo adhesion rau lub substrate txawm nyob rau ntawm ib tug tuab ntawm 30μm los yog ntau tshaj, nrog tsawg brittleness; columnar siv lead ua qauv, ua rau zoo corrosion kuj tshaj zinc plating daws; zoo tshuaj stability.
Zinc Plating
Qhov zoo ntawm zincate zinc plating: zoo siv lead ua qauv, zoo gloss, dispersion thiab sib sib zog nqus plating peev nyob ze rau cyanide plating; ruaj khov thiab tsis yog -cov tshuaj corrosive, haum rau electroplating complex- zoo li qhov chaw; dej khib nyiab yog yooj yim kho.
Chloride Zinc Plating
Chloride zinc plating daws muaj peb qhov txhawb nqa electrolytes. Vim muaj kev txhawb nqa electrolytes sib txawv, cov kev daws teeb meem plating poob rau hauv peb pawg tseem ceeb: ib qho ntawm cov tshuaj ammonium chloride, ib qho ntawm cov tshuaj poov tshuaj chloride, thiab lwm yam muaj cov tshuaj sodium chloride. Muab piv rau peb qhov kev txhawb nqa electrolytes, ammonium chloride tov muaj qhov zoo tshaj plaws conductivity thiab muaj peev xwm loj tshaj plaws rau cov neeg nqa khoom brighteners.
Sulfate Zinc Plating
Qhov zoo ntawm sulfate zinc plating: yooj yim muaj pes tsawg leeg, tsis tshua muaj nqi, muaj peev xwm siv tau ntau dua tam sim no, thiab feem ntau tsis tas yuav tsum tau passivation tom qab plating.
