Mtundu TACHIMATA zitsulo mbale amatchedwanso organic yokutidwa zitsulo mbalekapena mbale yachitsulo yopangidwa kale. Monga njira yopititsira patsogolo yopangira ma coils, mbale zachitsulo zamtundu zitha kugawidwa m'njira ziwiri: zokongoletsedwa ndi electro-galvanized ndi dip dip galvanized.
Panthawi imodzimodziyo, electro-galvanizing ndi njira yopangira utoto wopangidwa ndi golide- "wosanjikiza zinki zitsulo kapena aloyi ya zinki" kupyolera mu electroplating.
Hot-dip galvanizing, yomwe imadziwikanso kuti hot-dip galvanizing, ndikuviika zitsulo zomwe zimafunikira kukonza muzitsulo zosungunula za zinki kuti ziwoneke ngati zokutira zitsulo zokonza. Poyerekeza ndi electroplating, ❖ kuyanika zitsulo otentha-kuviika ndi thicker; pansi pa malo omwewo, amakhala ndi moyo wautali.
Kudzimbirira kwa galvanized wosanjikiza wotentha pamwamba pachitsulo kumakhala kofanana ndi zinki yoyera. Kuwonongeka kwa zinki mumlengalenga kumafanana ndi chitsulo chomwe chimawonongeka mumlengalenga. Chemical makutidwe ndi okosijeni dzimbiri zimachitika, electrochemical dzimbiri kumachitika pamwamba nthaka, ndi madzi filimu condensation kumachitika. M'malo osalowerera ndale kapena ofooka acidic, zinthu zowonongeka zomwe zimapangidwa ndi chitsulo chosungunuka zimakhala zosasungunuka (zinc hydroxide, zinc oxide, ndi zinc carbonate). Zogulitsa izi zidzalekanitsidwa ndi kuyikapo ndikupanga wosanjikiza wabwino kwambiri.
Nthawi zambiri imatha kufika makulidwe a 8μm”. Filimu yamtunduwu imakhala ndi makulidwe ake, koma sikuti imasungunuka m'madzi, ndipo imakhala yomatira kwambiri. Choncho, akhoza kusewera chotchinga pakati mlengalenga ndi kanasonkhezereka pepala. Pewani dzimbiri zina. Zosanjikiza zamagalasi zimawonongeka panthawi yokonza, ndipo mbali ina yazitsulo imawonekera mumlengalenga.
Panthawiyi, zinki ndi chitsulo zimapanga batri yaying'ono. Kuthekera kwa zinc ndikotsika kwambiri kuposa chitsulo. Monga anode, nthaka imakhala ndi mphamvu yapadera yokonza anode pa gawo lapansi lachitsulo kuti musawononge mbale yachitsulo.
Bolodi yokhala ndi utoto ndi mtundu wa zokutira zamadzimadzi, zomwe zimagwiritsidwa ntchito poyeretsa pamwamba pazitsulo ndi burashi kapena roller. Pambuyo pa kutentha ndi kuchiritsa, filimu ya utoto yokhala ndi makulidwe omwewo ingapezeke.
