Galvanized yeeb nkab
Khoom Description
I. Core Classification: Kev faib tawm los ntawm txheej txheem Galvanizing
Galvanized yeeb nkab feem ntau muab faib ua ob pawg: kub-dip galvanized yeeb nkab thiab txias-dip galvanized yeeb nkab. Ob hom no txawv heev hauv cov txheej txheem, kev ua haujlwm, thiab kev siv:
• Kub-dip galvanized yeeb nkab (kub-dip galvanized yeeb nkab): Tag nrho cov yeeb nkab steel yog immersed nyob rau hauv molten zinc, tsim ib tug uniform, ntom zinc txheej rau ntawm qhov chaw. Cov txheej zinc no feem ntau tshaj 85μm tuab, khav theeb muaj zog adhesion thiab zoo corrosion kuj, nrog rau kev pab cuam lub neej ntawm 20-50 xyoo. Tam sim no nws yog hom tseem ceeb ntawm cov yeeb nkab galvanized thiab tau dav siv hauv dej thiab roj faib, kev tiv thaiv hluav taws, thiab kev tsim vaj tsev.
• Cold-dip galvanized yeeb nkab (electrogalvanized yeeb nkab): zinc txheej yog tso rau ntawm cov yeeb nkab steel nto los ntawm electrolysis. Lub zinc txheej yog nyias (feem ntau 5-30μm), muaj zog adhesion, thiab muaj kev tiv thaiv corrosion tsawg tshaj li kub-dip galvanized yeeb nkab. Vim nws qhov kev ua haujlwm tsis txaus, cov kav dej galvanized tam sim no raug txwv tsis pub siv hauv cov ntawv thov uas xav tau kev tiv thaiv corrosion siab, xws li cov kav dej haus. Lawv tsuas yog siv nyob rau hauv qhov txwv tsis pub muaj nyob rau hauv cov ntaub ntawv uas tsis yog-load-bearing thiab tsis-dej-txog daim ntaub ntawv, xws li kho kom zoo nkauj thiab sib sib zog nqus brackets.
II. Qhov Zoo Tshaj Plaws
1. Muaj zog Corrosion Resistance: zinc txheej cais cov yeeb nkab steel los ntawm huab cua thiab noo noo, tiv thaiv xeb. Cov kav dej kub-dip galvanized, tshwj xeeb tshaj yog, tuaj yeem siv tau ntev hauv qhov chaw hnyav xws li cov av noo thiab sab nraum zoov.
2. Lub zog muaj zog: khaws cov khoom siv hluav taws xob ntawm cov kav dej carbon steel, lawv tuaj yeem tiv taus qee qhov kev ntxhov siab thiab qhov hnyav, ua rau lawv tsim nyog rau kev siv xws li kev txhawb nqa thiab kev thauj mus los.
3. Tus nqi tsim nyog: Piv rau cov kav hlau tsis muaj steel, cov kav dej galvanized muaj cov nqi tsim khoom qis dua. Muab piv rau cov pa roj carbon zoo tib yam, thaum cov txheej txheem galvanizing cov nqi nce, lawv lub neej kev pab cuam tau txuas ntxiv, ua rau muaj kev siv nyiaj ntau dua.
III. Cov ntawv thov tseem ceeb
• Kev Lag Luam Kev Tsim Kho: Siv rau hauv cov kav dej tiv thaiv hluav taws, cov kav dej thiab cov kav dej (cov dej tsis siv tau), cov kav dej cua sov, cov ntaub thaiv phab ntsa txhawb nqa, thiab lwm yam.
• Industrial Sector: Siv los ua cov kav dej thauj khoom (xws li dej, chav dej, thiab cua compressed) thiab cov khoom siv hauv cov chaw ua haujlwm hauv lub hoobkas.
• Kev Ua Liaj Ua Teb: Siv hauv cov kav dej ua liaj ua teb, cov tsev cog khoom txhawb nqa, thiab lwm yam.
• Kev thauj mus los: Siv me me los ua cov kav dej hauv lub hauv paus rau txoj kev loj guardrails thiab txoj kev teeb ncej (feem ntau yog cov kav dej kub-dip galvanized).
