1.Dab tsi yog qhov txawv ntawm kev tiv thaiv -corrosion mechanism ntawm galvanized kauj thiab npib tsib xee-plated kauj?
Corrosion Protection Mechanism: Sacrificial Anode
Zinc yog chemically reactive dua hlau. Thaum cov zinc txheej yog khawb los yog puas, nthuav tawm lub hauv paus hlau, zinc ua raws li "anode" thiab corrodes nyiam, thaum hlau, ua raws li "cathode," tiv thaiv. Cov txheej txheem no txuas ntxiv mus txog thaum cov zinc txheej tau noj tag nrho. Qhov no yog qhov tseem ceeb ntawm galvanizing.

Corrosion Protection Mechanism: Kev Tiv Thaiv Kev Tiv Thaiv
Nickel is a highly inert metal that forms an extremely thin and dense passivation film on its surface, effectively blocking external corrosive media (such as moisture and oxygen) from contacting the underlying steel substrate. Nws ua zoo li airtight "s armor" rau cov hlau.
2.Dab tsi yog cov yam ntxwv ntawm kev tiv thaiv -corrosion nyhuv ntawm galvanized coils?
Ntev ntev - kav ntev: Nyob rau hauv cov huab cua ib puag ncig, zinc txheej muab ntau xyoo los yog ntev dua ntawm kev tiv thaiv, nyob ntawm seb qhov tuab ntawm zinc txheej.
Tus kheej- kho: Cov txheej txheem "kho" me me khawb thiab txiav, tiv thaiv lub hauv paus hlau los ntawm xeb.
Dawb xeb: Nyob rau hauv cov av noo, qhov cua tsis zoo, cov zinc txheej reacts nrog dej thiab carbon dioxide los tsim cov zinc carbonate dawb (dawb xeb). Txawm hais tias qhov no tuaj yeem cuam tshuam rau cov tsos, nws feem ntau tsis cuam tshuam nws cov khoom tiv thaiv. Cov tsos ntawm xeb liab (ferrous xeb) yog ib qho cim ntawm kev ua tsis tiav.
Alkali kuj tau txais, tab sis acid kuj tsis zoo: Zinc tsis ruaj khov nyob rau hauv ob qho tib si acidic thiab alkaline ib puag ncig, tab sis nws kuj ruaj khov nyob rau hauv ib puag ncig nrog pH ntawm 6-12.
3.Dab tsi yog cov yam ntxwv ntawm nickel-plated coil los tiv thaiv-corrosion effect?
High Decorative tus nqi thiab ruaj khov: Cov nickel txheej muaj qhov zoo nkauj zoo nkauj thiab ruaj khov heev nyob rau hauv atmospheric thiab ntau qhov chaw muaj kev lag luam, tiv thaiv tsis muaj xim thiab tswj nws cov luster ntev.
Tsis Muaj Tus Kheej -Kev Muaj Peev Xwm Zoo: Thaum cov txheej npib tsib xee raug khawb, nthuav tawm cov hlau hauv qab, corrosion yuav pib ntawm qhov ntawd. Vim tias cov hlau muaj zog ntau dua li npib tsib xee, qhov no tsim qhov tsis zoo "me me anode- loj cathode" qhov xwm txheej, ua rau corrosion ntawm cov hlau substrate kom muaj zog ntawm qhov khawb thiab nrawm.
Cov tshuaj tiv thaiv zoo heev: Nws muaj kev tiv thaiv zoo rau alkalis, tsis muaj zog hauv paus, thiab qee cov organic acids. Qhov no ua rau nws tsim nyog rau kev siv hauv kev lag luam tshuaj thiab zaub mov.
Cov teeb meem porosity: Electroplated npib tsib xee txheej yuav muaj cov pores me me, los ntawm cov xov xwm corrosive tuaj yeem nkag mus rau hauv cov substrate. Cov txheej txheem "piv tooj liab plating + sab saum toj nickel plating" lossis "multi- txheej nickel" txheej txheem feem ntau yog siv los daws qhov teeb meem no.
4.Thaum twg xaiv galvanized kauj?
Lub hom phiaj tseem ceeb: Kev lag luam thiab tiv thaiv xeb ntawm cov qauv hlau.
Daim Ntawv Thov Ib puag ncig: Sab nraum zoov atmospheric ib puag ncig (xws li cov tsev thiab cov chaw thauj mus los), thiab cov chaw lag luam dav dav.
Cov peev nyiaj tsawg tsawg, thiab kev zoo nkauj tsis yog qhov tseem ceeb.
Cheebtsam tej zaum yuav raug khawb thiab dents, yuav tsum tau tus kheej -kev tiv thaiv zoo.
Daim ntawv thov: Agricultural irrigation equipment,》delivery sorting racks, cable trays, water pipelines, and automotive interior components.
5.Thaum twg xaiv nickel-plated kauj?
Lub hom phiaj tseem ceeb: Kev xeb zoo heev thiab hnav tsis kam ua ke nrog qhov zoo nkauj zoo nkauj.
Yuav tsum muaj hluav taws xob zoo conductivity (xws li, rau cov khoom siv hluav taws xob).
Daim ntawv thov ib puag ncig: raug tshuaj lom neeg, yuav tsum tau yooj yim - rau- huv qhov chaw (xws li, chav ua noj thiab chav dej), los yog raug rau cov av noo nyob hauv tsev rau lub sijhawm ntev.
Muaj peev xwm txaus.
Cov ntawv thov raug: Siab-kawg faucets, chav dej hauv chav ua noj, khoom siv kho mob, roj teeb casings, hluav taws xob connectors, suab grilles, thiab txiaj.
