Dab tsi yog qhov kub ntawm chav da dej?
Acid zinc plating feem ntau yog 20-40 degree, alkaline zinc plating 40-60 degree. Qhov kub thiab txias dhau tuaj yeem yooj yim decompose cov additives, thaum kub qis heev tuaj yeem ua rau qeeb tus nqi deposition.
Dab tsi yog qhov txheej txheem txheej thickness yuav tsum tau?
Rau kev tiv thaiv corrosion dav dav, qhov yuav tsum tau muaj yog 5-15μm, thaum muaj zog tiv thaiv corrosion (xws li cov khoom siv tsheb), 15-30μm yuav tsum tau. Cov kev cai tshwj xeeb yog txiav txim siab los ntawm cov qauv khoom.
Dab tsi yog "leveling agent"? Nws txoj haujlwm yog dab tsi?
Kuj tseem hu ua tus neeg sawv cev theem, nws txhim kho qhov kev faib tawm tam sim no, kom ntseeg tau tias muaj cov txheej txheem ntau dua ntawm cov txheej txheem nyuaj (xws li qhov sib sib zog nqus thiab cov ces kaum), thiab tiv thaiv cov cheeb tsam ntawm cov thinness ntau dhau.
Vim li cas thiaj yuav tsum tau passivation tom qab electrogalvanizing? Zinc txheej nws tus kheej yog raug rau oxidation. Passivation (such as chromate passivation and chromium-free passivation) forms a dense passive film on the surface, significantly improving corrosion resistance.
Dab tsi yog qhov txawv ntawm cyanide - dawb zinc plating thiab cyanide - muaj zinc plating?
Cyanide- dawb zinc plating siv ib puag ncig tus phooj ywg chelating cov neeg ua haujlwm los hloov cov tshuaj lom cyanide. Nws muaj kev nyab xeeb heev thiab muaj kuab paug tsawg, tab sis nws yuav tsum tau tswj cov txheej txheem nruj dua. Cyanide zinc plating muaj cov txheej txheem ruaj khov, tab sis muaj kev pheej hmoo ib puag ncig thiab maj mam hloov.
