Umbhobho owenziwe ngegalvanized
Inkcazelo emfutshane:
Umbhobho ofakwe igalvanized, owaziwa ngokuba ngumbhobho wentsimbi, wahlulwe waba yigalvanizing eshushu kunye ne-electro galvanizing.I-hot-dip galvanizing layer ingqindilili kwaye ineenzuzo zokwaleka okufanayo, ukuncamathela okuqinileyo kunye nobomi benkonzo ende.Iindleko ze-electro galvanizing ziphantsi, umphezulu awugudi kakhulu, kwaye ukuchasana kwayo nokugqwala kubi kakhulu kunombhobho we-galvanized dip-dip.
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 ezisemantla zamkela inkqubo yokuqengqeleka ngokuthe ngqo kombhobho nge-galvanized strip yokongeza i-zinc.
