Kub dip galvanizingyog ib txoj kev siv dav dav los tiv thaiv hlau los ntawm kev xeb. Cov txheej txheem muaj ntau kauj ruam tseem ceeb, suav nrog kev kho ua ntej, uas yog qhov tseem ceeb rau kev ua kom zoo thiab ruaj khov ntawm cov txheej txheem galvanized. Ib qho tseem ceeb ntawm kev kho ua ntej yog kev siv cov thoob dej degreasing nrog rau cua sov los npaj nws rau cov txheej txheem galvanizing.
Kauj ruam thawj zaug hauv cov txheej txheem galvanizing kub-dip yogkev kho mob ua ntej, uas cuam tshuam txog kev ntxuav cov hlau kom tshem tawm cov khoom tsis huv uas yuav cuam tshuam rau cov txheej txheem galvanizing. Qhov no feem ntau ua tiav hauv lub tank degreasing, qhov twg cov hlau raug muab tso rau hauv cov kua alkaline kub kom tshem tawm cov roj, roj lossis lwm yam organic residues ntawm qhov chaw. Lub tank degreasing yog ib feem tseem ceeb ntawmtxheej txheem ua ntej kev kho mobvim nws ua kom cov hlau raug ntxuav kom huv si ua ntej raug galvanized.
Thaum cov hlau raug ntxuav hauv lub tank degreasing, nws tuaj yeem ua tauua ntej cua sovKauj ruam no yog ua kom cov hlau sov kom tshem tawm cov dej noo uas tseem tshuav thiab npaj qhov chaw rau cov txheej txheem galvanizing. Kev ua kom cov hlau sov yog qhov tseem ceeb vim nws pab ua kom cov txheej galvanized lo rau ntawm qhov chaw kom zoo, ua rau nws ruaj khov dua thiab siv tau ntev dua.
Thaum cov kauj ruam ua ntej kho tiav lawm, cov hlau npaj txhij raukub-dip galvanizingtxheej txheem. Qhov no suav nrog kev muab cov hlau tso rau hauv ib lub dab da dej ntawm cov zinc uas yaj, uas ua rau cov hlau sib txuas nrog cov hlau los tsim cov txheej tiv thaiv uas tiv taus xeb heev. Cov txheej txheem galvanizing tshwm sim ntawm qhov kub siab, feem ntau nyob ib puag ncig 450 ° C (850 ° F), kom ntseeg tau tias cov txheej zinc sib txuas zoo rau cov hlau.
Tom qab cov hlau raug galvanized, nws raug txias thiab kuaj xyuas kom paub tseeb tias cov txheej txheej yog sib npaug thiab tsis muaj qhov tsis zoo. Cov zinc ntau dhau raug tshem tawm, thiab cov hlau ces npaj txhij rau ntau yam kev siv, los ntawm kev tsim kho thiab kev tsim kho vaj tse mus rau tsheb thiab cov khoom siv hauv kev lag luam.
Hauv kev xaus lus, cov txheej txheem galvanizing kub-dip muaj ntau kauj ruam tseem ceeb, suav nrogkev kho mob ua ntej kub-dip galvanizing, kev siv cov tank tshem roj, thiab kev kho cua sov ua ntej. Cov kauj ruam no yog qhov tseem ceeb kom ntseeg tau tias cov hlau tau npaj kom zoo rau cov txheej txheem galvanizing, ua rau muaj cov txheej txheem zoo, ntev ntev uas muab kev tiv thaiv zoo tiv thaiv xeb. Los ntawm kev ua raws li cov kauj ruam no, cov chaw tsim khoom tuaj yeem ua kom ntseeg tau tias lawv cov khoom siv hlau galvanized ua tau raws li cov qauv zoo tshaj plaws thiab kev ua tau zoo.
