Hot dip galvanizing amatchedwanso otentha dip zinki ndi otentha kuviika galvanizing: ndi njira yothandiza ya dzimbiri zitsulo, makamaka ntchito m'mafakitale osiyanasiyana a zitsulo kapangidwe zipangizo.Ndiko kumiza zigawo zachitsulo pambuyo pochotsa dzimbiri mumadzi osungunuka a zinki pafupifupi 500 ℃, kotero kuti pamwamba pazitsulo zazitsulo zimamangiriridwa ndi nthaka wosanjikiza, kuti azisewera cholinga cha anticorrosion.Hot dip galvanizing ndondomeko: yomalizidwa pickling - kuchapa - kuwonjezera bafa thandizo - kuyanika - atapachika plating - kuzirala - mankhwala - kuyeretsa - akupera - otentha divi galvanizing kumaliza.Kutentha kwa dip galvanizing kumapangidwa kuchokera ku njira yakale yopangira dip galvanizing.Ili ndi mbiri ya zaka 140 kuchokera pamene idagwiritsidwa ntchito ku mafakitale ku France mu 1836. Komabe, mafakitale otentha a dip galvanizing apangidwa pamlingo waukulu m'zaka 30 zapitazo ndi chitukuko chofulumira cha waya wotentha wa dip galvanizing.
Greenhouse wapadera electroplating ndondomeko chitsulo waya blackening njira:
Chimodzi ndikuchita ntchito yabwinowaya wamalatama CD, kupewa kugunda, kuonetsetsa kukhulupirika kwa nthaka wosanjikiza;
Awiri ndi kulabadira kusungirako ndi ntchito kanasonkhezereka waya mankhwala, malinga ndi mfundo zenizeni zachilengedwe kusankha specifications zosiyanasiyana za kanasonkhezereka waya mankhwala;
Chachitatu ndi kuchita ntchito yabwino kupanga kanasonkhezereka waya mankhwala mwaukhondo ndi mwaudongo, mogwirizana ndi njira sayansi ntchito ntchito kupanga, woyendetsa ayenera kuvala chovala chofunika.Ngati kutentha kuviika kanasonkhezereka waya mankhwala, tiyenera kuchita ntchito yabwino ya passivation, adzatha mogwira kupewa ma discoloration, kutalikitsa njira kusinthika, angathe kuthetsa vuto la kusinthika.
