1. Cyanide galvanizing: Qhov zoo: Lub plating siv lead ua kom zoo, qhov peev xwm dispersing thiab npog muaj peev xwm ntawm cov plating daws tau zoo, thiab nws tsis muaj qhov cuam tshuam zoo rau cov khoom siv steel. Qhov tsis zoo: Cov tshuaj plating muaj cov tshuaj lom cyanide heev, thiab cov dej paug tawm thiab cov roj pov tseg yuav muaj teeb meem rau ib puag ncig.
2. Sulfate galvanizing: qhov zoo: tus nqi qis, ruaj khov plating daws, siab efficiency tam sim no, siab tso cai cathode ceev tam sim no, thiab ceev ceev ceev ceev. Qhov tsis zoo: lub peev txheej plating muaj peev xwm thiab qhov tob plating muaj peev xwm tsis zoo, cov plating siv lead ua yog tuab, thiab nws tsuas yog haum rau plating qhov chaw nrog cov qauv yooj yim. Lub plating daws muaj qhov ua tau zoo rau cov khoom siv steel.
3, tsis muaj zog acid potassium chloride galvanizing: qhov zoo: tsis muaj cyanide, plating kua muaj pes tsawg leeg yog yooj yim, ruaj khov, qis tus nqi ntau lawm, tam sim no kev ua haujlwm zoo, txuag hluav taws xob, ceev ceev ceev ceev, ntau lawm kev ua hauj lwm zoo, haum rau nrum hlau qhov chaw, siab carbon steel qhov chaw yog galvanized. Cov txheej xim yog qhov ci, kom ntxaws thiab muaj cov theem zoo. Qhov tsis zoo: Lub plating daws muaj qhov ua rau tsis zoo ntawm cov cuab yeej steel. Yog tias qhov kev kho mob tom qab tsis zoo, xim pleev xim hla passivation zaj duab xis muaj qhov tsis zoo ntsev tsuag tsis kam dua li alkaline galvanizing.
4. Ammoniatriacetic acid-ammonium chloride galvanizing: Cov txiaj ntsig zoo: Vim tias lub zog muaj peev xwm ntawm ammonia triacetic acid rau zinc, cov nyhuv cathodic polarization thaum zinc deposition yog nce ntxiv, thiab lub peev xwm dispersing thiab npog muaj peev xwm ntawm cov plating daws tau zoo dua. Cov txheej xim yog qhov ci dua. Qhov tsis zoo: Lub plating daws yog corrosive heev rau cov khoom siv steel.
5. Alkaline zincate galvanizing: Cov txiaj ntsig zoo: tsis muaj cyanide, tsis muaj xeb rau cov cuab yeej steel, zaj duab xis passivation tsis yooj yim hloov xim thiab dub hauv cov huab cua kub thiab noo. Qhov tsis zoo: Muaj qee qhov tsis sib txawv hauv qhov sib zog thiab qhov nkig ntawm cov xim sib piv rau zinc cyanide plating.
