Kev kub dip galvanizing yog ib txoj kev siv dav dav los tiv thaiv cov hlau los ntawm kev xeb. Nws muab cov hlau tso rau hauv ib lub dab dej ntawm cov zinc molten, tsim ib txheej tiv thaiv rau ntawm qhov chaw ntawm cov hlau. Cov txheej txheem no feem ntau hu ua alub lauj kaub zincvim nws yuav tsum muab cov hlau tso rau hauv lub lauj kaub uas muaj cov zinc yaj. Cov hlau galvanized uas tau los ntawm cov hlau no paub txog nws qhov ruaj khov thiab tiv taus xeb, ua rau nws yog qhov kev xaiv nrov rau ntau yam kev siv, txij li kev tsim kho mus rau kev tsim tsheb.
Ib lo lus nug uas feem ntau cuam tshuam nrogkub-dip galvanizingyog seb cov txheej zinc puas yuav ua rau cov hlau galvanized xeb dhau sijhawm. Txhawm rau daws qhov teeb meem no, nws yog ib qho tseem ceeb kom nkag siab txog cov yam ntxwv ntawm zinc thiab lawv cuam tshuam li cas nrog cov hlau substrate.
Zinc yog ib qho hlau uas muaj zog heev uas thaum siv rau hlau, nws ua rau cov hlau tsis yooj yim puas tsuaj.kub-dip galvanizing, tsim cov txheej zinc-hlau sib xyaw ua ke rau ntawm qhov chaw ntawm cov hlau. Cov txheej no muab ib qho kev thaiv lub cev, tiv thaiv cov hlau hauv qab los ntawm cov khoom xeb xws li dej noo thiab oxygen. Tsis tas li ntawd, cov txheej zinc ua haujlwm ua ib qho anode sacrificial, uas txhais tau tias yog tias cov txheej puas lawm, cov txheej zinc yuav xeb dua li cov hlau, ntxiv tiv thaiv cov hlau los ntawm kev xeb.
Feem ntau, cov txheej zinc rau ntawm cov hlau galvanized muab kev tiv thaiv xeb mus sij hawm ntev txawm tias nyob rau hauv qhov chaw ib puag ncig hnyav. Txawm li cas los xij, qee zaum, cov txheej galvanized tuaj yeem ua rau puas tsuaj, ua rau muaj peev xwm xeb ntawm cov hlau hauv qab. Ib qho xwm txheej zoo li no yog kev raug rau cov kua qaub lossis alkaline ib puag ncig, uas ua rau xeb ntawm cov txheej zinc sai dua thiab ua rau nws cov khoom tiv thaiv puas tsuaj. Tsis tas li ntawd, kev raug rau qhov kub siab ntev tuaj yeem ua rau cov txheej zinc puas tsuaj, ua rau xeb ntawm cov hlau substrate.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum lub sijhawm ua haujlwm ntawm zinc txheej, cov khoom siv zinc txheej yuav tsum tau ua tib zoo saib xyuas.hlau galvanizedNws zoo heev rau kev tiv thaiv cov hlau ntawm kev xeb, nws tsis tiv thaiv kev puas tsuaj. Kev puas tsuaj ntawm lub tshuab, xws li khawb lossis gouges, tuaj yeem ua rau lub zinc txheej puas tsuaj thiab ua rau cov hlau hauv qab muaj kev pheej hmoo ntawm kev xeb. Yog li ntawd, kev tuav thiab kev saib xyuas cov khoom siv hlau galvanized kom zoo yog qhov tseem ceeb kom ntseeg tau tias lawv tiv taus kev xeb mus sij hawm ntev.
Xaus lus,kub dip galvanizing, tseem hu ua zinc lauj kaub, yog ib txoj hauv kev zoo los tiv thaiv cov hlau los ntawm kev xeb.Kev kho kom zoo nkaujtsim ib txheej tiv thaiv ruaj khov rau ntawm qhov chaw hlau, muab kev tiv thaiv xeb mus sij hawm ntev hauv feem ntau ib puag ncig. Txawm hais tias cov txheej galvanized tuaj yeem puas tsuaj nyob rau hauv qee qhov xwm txheej, kev saib xyuas thiab kev tuav cov khoom hlau galvanized kom zoo pab ua kom lawv tiv thaiv xeb mus ntxiv. Zuag qhia tag nrho, hlau galvanized tseem yog qhov kev xaiv txhim khu kev qha thiab ruaj khov rau ntau yam kev siv vim yog cov khoom tiv thaiv ntawm zinc txheej.
