Tin free sheet sheet coil Electrolytic chromic acid treatment

Koyilo yachitsulo ya Chrome imatanthawuza mbale yachitsulo yokutidwa ndi chromium. Pofuna kupewa dzimbiri pamwamba pa mbale yachitsulo ndikutalikitsa moyo wake wautumiki, chitsulo cha chromium chimakutidwa pamwamba pa mbale yachitsulo. Chrome plating ndi njira yomwe imagwiritsidwa ntchito pafupipafupi komanso yothandiza polimbana ndi dzimbiri. Kuchuluka kwa ayoni a chromium mu electrolyte kuyenera kusamalidwa powonjezera pafupipafupi zosakaniza za chromium mu njira yopumira. Mapangidwe a koyilo ya chromium ali ndi zigawo zinayi: gawo lapansi lachitsulo, chitsulo cha chromium wosanjikiza, hydrated chromium oxide wosanjikiza ndi filimu yamafuta. Popeza gawo lapansi ndilofanana, mawonekedwe amakina ndi ofanana ndi mbale ya malata, The chromium-yokutidwa ndi coil imatenga mbale yachitsulo yocheperako ya carbon structural, koma wosanjikiza wa chromium ndi woonda kwambiri (<1.3μm), ndi njira yake. n'chimodzimodzi ndi tin-plated mbale.etc.
