Los ntawm cov seem ntawm cov zinc tshauv, nws tuaj yeem pom tias ntxiv rau zinc oxide ua cov khoom tseem ceeb, zinc tshauv tseem muaj lwm cov oxides xws li txhuas oxide, antimony oxide, chlorides, hlau, thiab acid-insoluble impurities. Yog li ntawd, lub xub ntiag ntawm cov tshuaj no tuaj yeem ua rau muaj kev cuam tshuam ntau yam ntawm cov kav hlau galvanized. Cov teebmeem no tshwm sim raws li hauv qab no:
(1) Zinc tshauv ntawm qhov kub siab dua zaum ntawm qhov chaw ntawm zinc molten. Cov kav hlau hlau pib raus rau hauv cov zinc molten tom qab dhau los ntawm zinc tshauv. Yog li ntawd, cov kuab tshuaj yuav raug hlawv tawm, ua rau thaj chaw tsis muaj coated.
(2) Zinc tshauv tuaj yeem nkag mus rau cov kuab tshuaj seem thiab lwm yam impurities. Yog hais tias cov residues ua raws li cov kav hlau uas yuav tsum tau galvanized, lawv yuav tsis tau txais cov zinc txheej, tab sis lawv kuj yuav raug muab tso rau hauv cov zinc txheej ntshiab. Thaum cov kav hlau galvanized nqus dej noo los ntawm huab cua, cov chlorides hauv cov khoom seem no hnov mob nrog dej los tsim cov xov xwm corrosive, ua kom cov xeb ntawm cov zinc txheej ntshiab thiab ua rau nws poob rau hauv cov kua muag zoo li streaks, ua rau muaj kev puas tsuaj. Thaum cov kav hlau galvanized tawm los ntawm cov zinc molten, cov kuab tshuaj (flux) residues kuj tuaj yeem ua raws li cov kav dej sab nrauv, ua rau corrosion ntawm cov chaw no tom qab nqus dej noo los ntawm huab cua.
(3) Zinc tshauv tuaj yeem muaj cov pa roj carbon monoxide coj los ntawm cov txheej txheem pickling ntawm cov kav hlau, nrog rau cov pa roj carbon monoxide uas tshwm sim los ntawm kev tawg ntawm galvanizing pots thiab steel kav. Qhov no tuaj yeem ua rau pom qhov chaw tsis muaj coated ntawm galvanized txheej txheej. Txawm hais tias ib txheej hlau-zinc alloy tseem muaj nyob rau hauv, nws yog thinner dua li ib puag ncig cov zinc txheej, cuam tshuam rau lub neej kev pab cuam.
(4) Qhov muaj ntau ntawm zinc tshauv tuaj yeem ua rau qhov zoo ntawm cov zinc molten, tshwj xeeb tshaj yog ua rau sab saum toj txheej ntawm molten zinc thicker.
(5) Thaum zinc tshauv accumulates ntau dhau ntawm qhov molten zinc, ntau cov zinc tshauv tuaj yeem ua raws li cov kav dej hlau thaum lawv tawm hauv lub lauj kaub galvanizing. Yog tias tsis tam sim ntawd tshuab tawm thiab so tawm sab hauv thiab sab nraud, cov pob daj daj lossis thaj ua rau thaj yuav tshwm rau ntawm qhov chaw. Yog hais tias cov yeeb nkab steel raug xa tawm tam sim ntawd los ntawm cov menyuam conveyor thaum tawm hauv lub lauj kaub galvanizing, qhov hnyav ntawm cov kav hlau yuav nias cov zinc tshauv rau hauv cov zinc txheej ntshiab. Tsis tas li ntawd, raws li cov kav dej galvanized steel nce mus rau hauv kev dhia ntawm cov menyuam conveyor, linear distributions ntawm dotted daj zinc tshauv me ntsis yuav tshwm rau saum npoo. Yog tias cov zinc tshauv no tsis raug tshem tawm, cov tshuaj chlorides thiab lwm yam acidic impurities nyob rau hauv lawv yuav corrode galvanized txheej tom qab absorbing noo noo los ntawm huab cua. Thaum cov zinc tshauv ntawm cov pob no raug tshem tawm, cov pits yuav tshwm sim, thiab cov zinc txheej ntshiab yuav thinner los yog tsis tuaj, ua rau lub neej luv luv.
(6) Txij li zinc tshauv kuj muaj qee yam ntawm cov hlau, yog tias nws sib xyaw rau hauv cov zinc txheej ntshiab ntawm cov zinc molten, cov xim daj xeb tuaj yeem tshwm sim nyob rau hauv qee qhov ntub dej, thiab cov ntsiab lus tsis tseeb yuav tshwm sim thaum kuaj, cuam tshuam rau galvanizing. zoo.
