Kub dip galvanizingyog ib txoj kev siv dav los tiv thaiv hlau los ntawm corrosion. Cov txheej txheem suav nrog ntau cov kauj ruam tseem ceeb, suav nrog kev kho ua ntej, uas yog qhov tseem ceeb rau kev ua kom zoo thiab ua haujlwm ntev ntawm cov galvanized txheej. Ib qho tseem ceeb ntawm kev kho mob ua ntej yog kev siv cov degreasing tso tsheb hlau luam nrog rau cua sov los npaj rau txheej txheem galvanizing.
Thawj kauj ruam hauv cov txheej txheem kub-dip galvanizing yogkho ua ntej, uas cuam tshuam nrog kev tu cov hlau kom tshem tawm cov kab mob uas tuaj yeem cuam tshuam cov txheej txheem galvanizing. Qhov no feem ntau yog ua nyob rau hauv lub tank degreasing, qhov twg cov hlau yog immersed nyob rau hauv ib tug kub alkaline tov kom tshem tawm cov roj, roj los yog lwm yam organic residues los ntawm qhov chaw. Lub tank degreasing yog ib qho tseem ceeb ntawm lub tanktxheej txheem ua ntej khoraws li nws xyuas kom meej tias cov hlau yog huv si ua ntej yuav galvanized.
Thaum cov hlau raug ntxuav hauv lub tank degreasing, nws tuaj yeem ua taupre-rhuab. Cov kauj ruam no suav nrog cua sov cov hlau kom tshem tawm cov dej noo seem thiab npaj qhov chaw rau txheej txheem galvanizing. Cua sov cov hlau yog ib qho tseem ceeb vim nws pab xyuas kom meej tias cov galvanized txheej adheres rau saum npoo kom zoo, uas ua rau kom muaj kev ruaj khov thiab kav ntev.
Thaum cov kauj ruam ua ntej kev kho mob tiav, cov hlau yog npaj rau lubkub-dip galvanizingtxheej txheem. Qhov no yog immersing cov hlau nyob rau hauv ib da dej ntawm molten zinc, uas metallurgically bonds rau cov hlau los tsim ib tug heev corrosion-resistant txheej. Cov txheej txheem galvanizing yuav siv qhov chaw ntawm qhov kub thiab txias, feem ntau nyob ib ncig ntawm 450 ° C (850 ° F), kom ntseeg tau tias zinc txheej bonds zoo rau cov hlau.
Tom qab cov hlau yog galvanized, nws yog txias thiab tshuaj xyuas kom ntseeg tau tias cov txheej yog txawm thiab tsis muaj qhov tsis xws luag. Tshaj zinc raug tshem tawm, thiab cov hlau yog tom qab ntawd npaj rau ntau yam kev siv, los ntawm kev tsim kho thiab kev tsim kho tsheb mus rau tsheb thiab khoom siv.
Yuav kom ua tiav, cov txheej txheem kub-dip galvanizing muaj ob peb kauj ruam tseem ceeb, suav nrogpre-kho kub-dip galvanizing, siv cov degreasing tso tsheb hlau luam, thiab ua ntej kev kho cua sov. Cov kauj ruam no yog qhov tseem ceeb los xyuas kom meej tias cov hlau tau npaj tau zoo rau cov txheej txheem galvanizing, uas ua rau muaj cov txheej txheem zoo, cov txheej txheem ntev ntev uas muab kev tiv thaiv zoo tiv thaiv corrosion. Los ntawm kev ua raws li cov kauj ruam no, cov tuam ntxhab tuaj yeem xyuas kom meej tias lawv cov khoom siv galvanized steel ua tau raws li cov qauv zoo tshaj plaws thiab kev ua tau zoo.
