Cov Txheej Txheem Kub Galvanizing yog ib qho txheej txheem ntawm kev txheej ib txheej ntawm zinc rau saum npoo hlau kom tiv thaiv kev xeb. Cov txheej txheem no yog qhov tsim nyog rau cov hlau thiab cov khoom siv hlau, vim nws ua kom lub neej ntawm cov khoom siv ntev dua thiab txhim kho nws txoj kev tiv thaiv xeb. Cov txheej txheem dav dav ntawm kev kub-dip galvanizing suav nrog cov kauj ruam hauv qab no:
1. Kev kho ua ntej: Cov khoom siv hlau yog thawj zaug raug rau kev kho ua ntej ntawm qhov chaw, uas feem ntau suav nrog kev ntxuav, tshem roj, pickling thiab flux daim ntawv thov kom ntseeg tau tias qhov chaw hlau huv thiab tsis muaj impurities.
2. Kev Sib Tov: Cov hlau uas tau kho ua ntej lawm raug muab tso rau hauv cov kua zinc uas yaj uas kub txog li 435-530°C. Tom qab ntawd cov hlau raug muab tso rau hauv lub dab dej zinc uas yaj. Thaum kub siab, qhov chaw hlau yuav ua rau cov zinc sib xyaw ua ke los ua ib txheej zinc-hlau sib xyaw, uas yog ib qho txheej txheem uas cov zinc sib xyaw nrog qhov chaw hlau los ua ib qho kev sib txuas hlau.
3. Txias: Tom qab cov hlau raug tshem tawm ntawm cov kua zinc, nws yuav tsum tau txias, uas tuaj yeem ua tiav los ntawm kev txias ntuj, txias dej lossis cua txias.
4. Kev kho tom qab: Cov hlau galvanized txias yuav xav tau kev tshuaj xyuas thiab kev kho ntxiv, xws li tshem tawm cov zinc ntau dhau, passivation kom txhim kho kev tiv thaiv xeb, thiab roj lossis lwm yam kev kho saum npoo kom muab kev tiv thaiv ntxiv.
Cov yam ntxwv ntawm cov khoom siv galvanized kub muaj xws li kev tiv taus xeb zoo heev, ua haujlwm tau zoo thiab kho kom zoo nkauj. Qhov muaj txheej zinc tiv thaiv cov hlau los ntawm kev xeb los ntawm kev ua haujlwm ntawm sacrificial anode, txawm tias thaum txheej zinc puas lawm. Tsis tas li ntawd, cov txheej txheem ntawm kev tsim txheej galvanizing kub muaj xws li kev tsim cov txheej zinc-hlau alloy los ntawm kev yaj ntawm qhov chaw hlau los ntawm cov kua zinc, kev sib kis ntxiv ntawm cov zinc ions hauv cov txheej alloy mus rau hauv lub substrate los tsim cov txheej zinc-hlau intercalation, thiab kev tsim cov txheej zinc ntshiab ntawm qhov chaw ntawm cov txheej alloy.
Kev siv galvanizing kub-dip yog siv rau ntau yam kev siv, suav nrog cov qauv tsev, kev thauj mus los, metallurgy thiab kev khawb av, kev ua liaj ua teb, tsheb, khoom siv hauv tsev, khoom siv tshuaj lom neeg, kev ua roj av, kev tshawb nrhiav hauv dej hiav txwv, cov qauv hlau, kev xa hluav taws xob, kev tsim nkoj thiab lwm yam. Cov qauv txheem rau cov khoom siv galvanized kub-dip suav nrog tus qauv thoob ntiaj teb ISO 1461-2009 thiab tus qauv hauv tebchaws Suav GB / T 13912-2002, uas qhia meej txog qhov yuav tsum tau ua rau cov txheej txheem galvanized kub-dip tuab, qhov loj me ntawm cov profile thiab qhov zoo ntawm qhov chaw.
