Plating Process - Mtundu Umodzi Wa Chithandizo Chapamwamba

Plating Process

Njira ya electroplatingndi njira ❖ kuyanika kondakitala ndi wosanjikiza zitsulo ntchito mfundo electrolysis.Electroplating imatanthawuza njira yopangira pamwamba pomwe chitsulo choyambira chimagwiritsidwa ntchito ngati cathode mumchere wothira mchere wokhala ndi zitsulo zokutidwa kale, ndipo ma cations a zitsulo zopukutidwa kale muzitsulo zomata zimayikidwa pamwamba pa chitsulo. zitsulo zoyambira kudzera mu electrolysis kupanga zokutira.

Zomwe zimapangidwira ndizosiyana ndi zitsulo zoyambira ndipo zimakhala ndi makhalidwe atsopano.Malingana ndi ntchito yophimba, imagawidwa kukhala yotetezera, yokongoletsera ndi zina zogwirira ntchito.

Panthawi ya electroplating, chitsulo chosungunuka kapena zinthu zina zosasungunuka zimagwiritsidwa ntchito ngati anode, chogwiritsira ntchito kuti chipangidwe chimagwiritsidwa ntchito ngati cathode, ndipo ma cations a zitsulo zowonongeka amachepetsedwa pamwamba pa workpiece kuti apangidwe kuti apange wosanjikiza. .Itha kukulitsa kukana kwachitsulo kwachitsulo (chitsulo chokwirira chimakhala chitsulo chosapanga dzimbiri), kukulitsa kuuma, kupewa kuvala, kukonza madulidwe, kusalala, kukana kutentha ndi kukongola kwapamwamba.

Zofunika

Electroplatingndi njira ya electrochemical komanso njira ya redox.Njira yayikulu ya electroplating ndikumiza gawolo mumchere wachitsulo monga cathode, mbale yachitsulo ngati anode,amphamvu ya DC ikayatsidwa, zokutira zomwe mukufuna zimayikidwa pagawolo.

Ndondomeko yonse: 1. Pickling → mbale yodzaza ndi electroplating

Mkuwa → kutengera chitsanzo → kutsitsa asidi → kutsuka kwachiwiri → kupukuta pang'ono → kutsekemera pang'ono → ku pickling → kulata → malata → kuchapa kachiwiri 2, kuthirira kobwerezabwereza → pickling → kupukuta → kuchapa kwachiwiri → kuchapa kwa faifi tambala → kuviika kwa nickel → mulingo wachiwiri wochapira citric acid → plating golide → kubwezeretsanso → mlingo 2-3 kutsuka madzi oyera → kuyanika.
