Ubuninzi be-hot-dip galvanized layer ineenzuzo zokugquma okufanayo, ukunamathela okuqinileyo, ubomi obude benkonzo kunye nokunye.Ixabiso le-galvanizing liphantsi, umphezulu awululanga kakhulu, kwaye ukuxhathisa ukubola kubi kakhulu kunombhobho we-galvanized dip.Inkqubo yokwenziwa kwe-hot-dip galvanizing layer yinkqubo yokwenza i-iron zinc alloy phakathi kwe-iron matrix kunye ne-zinc ecocekileyo engaphandle.I-iron zinc alloy layer yenziwa kumphezulu we-workpiece ngexesha le-hot-dip galvanizing, eyenza ukudibanisa okulungileyo phakathi kwentsimbi kunye ne-zinc ecocekileyo.Inkqubo inokuchazwa nje ngokuba: xa i-workpiece yentsimbi ifakwe kwi-zinc etyhidiweyo, i-zinc slag.Xa i-workpiece isusiwe kwisisombululo sokucwiliswa kwe-zinc, i-zinc ecocekileyo yenziwa phezu komhlaba, eyi-crystal ene-hexagonal.Umxholo wayo wentsimbi awukho ngaphezu kwe-0.003%.
Umbhobho wediphu oshushu:
Kukwenza isinyithi esityhidiweyo siphendule nge-matrix yentsimbi ukuvelisa i-alloy layer, ukwenzela ukudibanisa i-matrix kunye ne-coating.Ukugalela idiphu eshushu kukuchola umbhobho wentsimbi kuqala.Ukuze ukususa intsimbi oxide phezu kombhobho wentsimbi, emva pickling, icocwe ammonium chloride okanye zinc chloride isisombululo aqueous okanye ammonium chloride kunye nezinki chloride exutywe nesisombululo aqueous itanki, kwaye emva koko ithunyelwe kwidiphu eshushu galvanizing itanki.I-Hot dip galvanizing ineenzuzo zokugquma okufanayo, ukunamathela okuqinileyo kunye nobomi benkonzo ende.Uninzi lweenkqubo zaseMantla zamkela inkqubo yokuqengqeleka ngokuthe ngqo komcu wegalvanized ukongeza i-zinc.I-matrix yombhobho wensimbi kunye nesisombululo se-plating esityhidiweyo sineempendulo eziyinkimbinkimbi zomzimba kunye neekhemikhali, zenza i-zinc-resistant-resistant iron alloy layer kunye nesakhiwo esiqinileyo.Uluhlu lwe-alloy luhlanganiswe kunye ne-zinc ecocekileyo kunye ne-matrix yombhobho wensimbi.Ngoko ke, inokumelana ne-corrosion enamandla.
