Unyango lweSteel Surface - Inkqubo yokuDitshwa kweGalavanizing eshushu

I-Hot Dipped Galvanizing Process yinkqubo yokugquma umphezulu wesinyithi kunye nomaleko we-zinc ukuthintela ukubola. Le nkqubo ifaneleka ngokukhethekileyo kwizinto zetsimbi kunye nentsimbi, njengoko yandisa ngokufanelekileyo ubomi bezinto eziphathekayo kwaye iphucula ukuxhathisa ukubola. Inkqubo jikelele yokugalela amanzi ashushu iquka la manyathelo alandelayo:

1. Unyango lwangaphambili: Izinto zensimbi ziqala ukuthotyelwa phantsi konyango lwangaphambili, oluhlala lubandakanya ukucocwa, ukucocwa, ukucocwa kunye nesicelo se-flux ukuqinisekisa ukuba isinyithi sicocekile kwaye sikhululekile kwizinto ezingcolileyo.
2. I-Dip Plating: Intsimbi efakwe ngaphambili ifakwe kwisisombululo se-zinc esityhidiweyo sishushu malunga ne-435-530 ° C. Emva koko intsimbi ifakwa kwibhafu yezinki etyhidiweyo. Kwiqondo lokushisa eliphezulu, umgangatho wensimbi uphendula kunye ne-zinc ukwenza i-zinc-iron alloy layer, inkqubo apho i-zinc idibanisa kunye nentsimbi yensimbi ukuze yenze i-metallurgical bond.
3. Ukupholisa: Emva kokuba intsimbi isuswe kwisisombululo se-zinc, kufuneka ipholile, enokuthi iphunyezwe ngokupholisa kwendalo, ukupholisa kwamanzi okanye ukupholisa umoya.
4. Emva kokunyanga: Intsimbi epholileyo epholileyo inokufuna ukuhlolwa kunye nonyango olongezelelweyo, njengokususwa kwe-zinc engaphezulu, i-passivation yokuphucula ukuxhathisa kwe-corrosion, kunye ne-oiling okanye ezinye iindlela zonyango zokubonelela ngokhuseleko olongezelelweyo.
Iipropathi zeemveliso ezifakwe kwi-galvanized ze-hot-dip ziquka ukuxhathisa okugqwesileyo kwe-corrosion, ukusebenza kakuhle kunye neempawu zokuhombisa. Ubukho be-zinc layer bukhusela intsimbi kwi-corrosion ngokusebenzisa isenzo se-anode yedini, nangona i-zinc layer yonakaliswa. Ukongeza, inkqubo yokwakhiwa kwe-galvanizing layer ye-zinc-iron ngokuchithwa kwesiseko sesinyithi ngesisombululo se-zinc, ukusasazwa ngakumbi kwee-ion ze-zinc kuluhlu lwe-alloy kwi-substrate ukwenza umaleko we-zinc-iron intercalation, kunye nokwakheka komgangatho ococekileyo we-zinc layer kumphezulu we-zinc.

 

I-Hot-dip galvanizing isetyenziswa kwiintlobo ezininzi zezicelo, kubandakanywa izakhiwo zokwakha, ukuthutha, isinyithi kunye nemigodi, ezolimo, iimoto, izixhobo zasekhaya, izixhobo zamakhemikhali, ukuqhutyelwa kwepetroleum, ukuhlola olwandle, izakhiwo zetsimbi, ukuhanjiswa kwamandla, ukwakhiwa kweenqanawa kunye nezinye iindawo. Iinkcazo ezisemgangathweni kwiimveliso ezifakwe kwi-galvanized ye-hot-dip zibandakanya umgangatho wamazwe ngamazwe we-ISO 1461-2009 kunye nomgangatho wesizwe waseTshayina we-GB/T 13912-2002, ochaza iimfuno zobunzima bomaleko we-galvanized we-hot-dip, imilinganiselo yeprofayili kunye nomgangatho womphezulu.
