Kutuluka kwa mzere annealing kumatanthauza kuti recrystallization annealing otentha kapena ozizira adagulung'undisa zitsulo mbale ikuchitika pansi mtundu annealing ng'anjo kapena chivundikiro annealing ng'anjo pamaso kulowa otentha plating waya mzere, kuti palibe njira annealing mu kanasonkhezereka. mzere.Chitsulo mbale ayenera kukhala woyera yogwira pamwamba chitsulo koyera, wopanda oxides ndi dothi zina, pamaso otentha divi galvanizing.Mu njira iyi, annealed pamwamba okusayidi pepala poyamba kuchotsedwa ndi pickling njira, ndiyeno wokutidwa ndi wosanjikiza nthaka kolorayidi kapena osakaniza ammonium kolorayidi ndi nthaka kolorayidi zosungunulira kuteteza, kuteteza mbale kukhala oxidized kachiwiri.
Njira imeneyi zambiri ntchito otentha adagulung'undisa mbale laminated monga zopangira, ndi annealed zitsulo mbale choyamba anatumiza ku msonkhano pickling, ndi asidi sulfuric kapena hydrochloric acid kuchotsa pamwamba zitsulo pepala mpweya otentha galvanizing njira.Pambuyo pickling, mbale zitsulo nthawi yomweyo kulowa thanki zilowerere ndi kuyembekezera kanasonkhezereka, amene angalepheretse reoxidation wa mbale zitsulo.Pambuyo pickling, kuyeretsa madzi, Finyani youma, kuyanika mu mphika nthaka, kutentha wakhala anakhalabe pa 445-465 ℃.
Hot dip galvanizing ndiye mafuta ndi chromed.Ubwino wa pepala lotenthetsera lopangidwa ndi njirayi umakhala bwino kwambiri poyerekeza ndi njira yonyowa yopangira malata.Ndiwofunika pakupanga pang'ono.Kusalekeza galvanizing kupanga mzere zikuphatikizapo mndandanda wa pretreatment ndondomeko, monga degreasing alkali, hydrochloric asidi pickling, kutsuka madzi, zosungunulira ❖ kuyanika, kuyanika, etc., ndi mbale choyambirira ayenera annealed mu ng'anjo chivundikirocho asanalowe mzere galvanizing.
