Unyango lweNsimbi yoMphezulu – Inkqubo yokuGcina iGalvanizing eshushu

Inkqubo ye-Hot Dipped Galvanizing yinkqubo yokugquma umphezulu wesinyithi ngomaleko we-zinc ukuthintela ukugqwala. Le nkqubo ifanelekile ngokukodwa kwizixhobo zentsimbi nezesinyithi, njengoko yandisa ubomi bezinto kwaye iphucula ukumelana nokugqwala kwayo. Inkqubo eqhelekileyo ye-hot-dip galvanizing ibandakanya la manyathelo alandelayo:

1. Unyango lwangaphambi kokulungiswa: Izinto zentsimbi ziqala zifakwe kumphezulu ngaphambi kokulungiswa, okuhlala kubandakanya ukucocwa, ukususwa kwamafutha, ukucolwa kunye nokusetyenziswa kwe-flux ukuqinisekisa ukuba umphezulu wesinyithi ucocekile kwaye awunazo izinto ezingcolileyo.
2. I-Dip Plating: Intsimbi elungisiweyo kwangaphambili ifakwa kwisisombululo se-zinc esinyibilikisiweyo esishushu ukuya kuthi ga kwi-435-530°C. Emva koko intsimbi ifakwa kwi-zinc bath enyibilikisiweyo. Kumaqondo obushushu aphezulu, umphezulu wentsimbi udibana ne-zinc ukwenza umaleko we-zinc-iron alloy, inkqubo apho i-zinc idibana nomphezulu wentsimbi ukwenza i-metallurgical bond.
3. Ukupholisa: Emva kokuba intsimbi isusiwe kwisisombululo se-zinc, kufuneka ipholiswe, nto leyo enokufezwa ngokupholisa kwendalo, ukupholisa ngamanzi okanye ukupholisa umoya.
4. Emva konyango: Intsimbi epholisiweyo egalelweyo ingadinga uhlolo nonyango olongezelelekileyo, njengokususwa kwe-zinc egqithisileyo, ukususwa kwe-passivation ukuphucula ukumelana nokugqwala, kunye ne-oyile okanye ezinye iindlela zonyango zomphezulu ukubonelela ngokhuseleko olongezelelekileyo.
Iimpawu zeemveliso ze-hot-dip galvanized ziquka ukumelana nokugqwala okugqwesileyo, ukusebenza kakuhle kunye neempawu zokuhombisa. Ubukho bomaleko we-zinc bukhusela intsimbi ekugqwaleni ngesenzo se-anode ye-sacrificial, nokuba umaleko we-zinc wonakele. Ukongeza, inkqubo yokwakheka komaleko we-hot-dip galvanizing ibandakanya ukwakheka komaleko we-zinc-iron alloy phase ngokunyibilikisa umphezulu wesiseko sesinyithi ngesisombululo se-zinc, ukusasazwa ngakumbi kwee-zinc ions kumaleko we-alloy kwi-substrate ukwenza umaleko we-zinc-iron intercalation, kunye nokwakhiwa komaleko we-zinc ococekileyo kumphezulu womaleko we-alloy.

 

I-hot-dip galvanizing isetyenziswa kwiintlobo ngeentlobo zezicelo, kuquka izakhiwo zezakhiwo, ezothutho, i-metallurgy kunye nemigodi, ezolimo, iimoto, izixhobo zasekhaya, izixhobo zamakhemikhali, ukucubungula ipetroli, uphando lwaselwandle, izakhiwo zesinyithi, uthumelo lwamandla, ukwakhiwa kweenqanawa kunye nezinye iindawo. Iinkcukacha ezisemgangathweni zeemveliso ze-hot-dip galvaning ziquka umgangatho wamazwe ngamazwe we-ISO 1461-2009 kunye nomgangatho wesizwe waseTshayina i-GB/T 13912-2002, ochaza iimfuno zobukhulu beleyara ye-hot-dip galvaning, ubungakanani beprofayili kunye nomgangatho womphezulu.
