I-annealing yangaphandle kuthetha ukuba ukufakwa kwakhona kwentsimbi eshushu okanye ebandayo kwipleyiti yentsimbi eqengqelekayo kuqhutywa kuhlobo olusezantsi lwesithando somlilo okanye uhlobo lwesithando somlilo ngaphambi kokungena kumgca wocwecwe olushushu, ukuze kungabikho inkqubo yokuqhobosha kwigalvanized. umgca.Ipleyiti yensimbi kufuneka igcine indawo ecocekileyo esebenzayo yentsimbi ecocekileyo, engenazo ii-oxides kunye nolunye ukungcola, ngaphambi kokuba idiphu ifake i-galvanizing.Kule ndlela, i-annealed surface oxide sheet isuswa kuqala nge-pickling method, kwaye igqunywe ngomqolo we-zinc chloride okanye umxube we-ammonium chloride kunye ne-solvent ye-zinc chloride yokukhusela, ukuze kuthintelwe ipleyiti ukuba iphinde ifakwe i-oxidized.
Le ndlela ngokubanzi ukusetyenziswa ipleyiti eshushu esongwayo elaminethiweyo njengento ekrwada, ipleyiti annealed steel ithunyelwa kuqala kwi workshop pickling, kunye sulfuric acid okanye hydrochloric acid ukususa umphezulu sheet sheet ioksijini indlela eshushu galvanizing.Emva kokukhetha, ipleyiti yensimbi ngokukhawuleza ingena kwi-tank ukuze idibanise kwaye ilinde i-galvanized, enokuthintela ukuphinda kufakwe i-plate yensimbi.Emva kokukhetha, ukucocwa kwamanzi, ukukhama, ukomisa, kwimbiza ye-zinc, ubushushu bugcinwe kwi-445-465 ℃.
Idiphu eshushu igalelwa ioli ifakwe ioyile kwaye ifakwe ichrome.Umgangatho weshiti elishushu elenziwe yile ndlela liphuculwe kakhulu xa lithelekiswa nolo ngendlela emanzi yokugalela.Ixabisekile kuphela kwimveliso encinci.Umgca wokuvelisa i-galvanizing oqhubekayo uquka uchungechunge lweenkqubo zokulungiswa kwangaphambili, ezifana ne-alkali degreasing, i-hydrochloric acid pickling, ukuhlamba amanzi, ukugquma kwe-solvent, ukomisa, njl.
