1.How Tus SecC piv rau SGCC piv?
Galvanizing txheej txheem: Secc txias txias {{k}}}}}}} follolytic Depepition (Qhov Chaw Zinc Electrolytic yog tso los ntawm hluav taws xob tam sim no; SGCC Kub-} {{{{{- dip galvanizing (immersing tus hlau nyob rau hauv molten zinc).
Zinc Txheej Thickness: Secc yog thinner, nrog ib qho tuab ntawm 5-20μm (8-12μm yog ib txwm tswj hwm; SGCC yog thicker, nrog ib tug tuab tuab ntawm 30-100μm (50-80μm yog ib txwm muaj), nrog ntau dua thickness variation.
Corrosion Repertance kuj: Secc Zinc Fewb (nyias, muaj kev tiv thaiv lub cev) thiab kev tiv thaiv anodic (nyias nyias zinc tau noj sai sai); SGCC Zinc Faib muab rwb thaiv tsev lub cev (cov txiaj ntsig kev pab cuam, muaj kev tiv thaiv muaj zog (tuab zinc txheej, lub sijhawm tiv thaiv ntev).
2.Yow yog qhov corrosion tiv taus nyob rau hauv ib puag ncig corrosive sab nraum zoov?
SGCC (Kub - dip galvanizing)> GA (Galvannealing)> Secc (electrolytic Galvanizing)
Core Yog vim li cas: Ob SGCC thiab GA tiv taus dawb (zinc oxidation), tab sis yog tias SECC tsis tshwm sim hauv 1-2 hlis, cuam tshuam rau cov tsos thiab lub neej; Yog tias SECC Undergoes "Xim Passivation" (xws li chromate passivation), cov xeb tawm tsam tuaj yeem txhim kho, tab sis nws tseem tsis zoo li qhov qub.
3.Qhov ib puag ncig sab hauv tsev, ib puag ncig corrosion tawm tsam?
SGCC ≈ Ga> Secc
Core Yog: Muaj tsawg dua corrosive media nyob rau hauv ib puag ncig qhuav, thiab cov zinc txheej ntawm peb hom galvanized steel tsis yooj yim noj. Qhov nyias nyias zinc txheej ntawm Secc kuj tseem tuaj yeem ua tau raws li kev siv ntawm 5-10 xyoo (xws li cov cuab yeej siv hauv tsev).
4.Yuas ib puag ncig sab hauv tsev, ib puag ncig corrosion tawm tsam?
SGCC ≈ Ga ≈ Secc
Core Yog: Muaj tsawg dua corrosive media nyob rau hauv ib puag ncig qhuav, thiab cov zinc txheej ntawm peb hom galvanized steel tsis yooj yim noj. Qhov nyias nyias zinc txheej ntawm Secc kuj tseem tuaj yeem ua tau raws li kev siv ntawm 5-10 xyoo (xws li cov cuab yeej siv hauv tsev).
5.Qhov dab tsi yog cov yam ntxwv tseem ceeb ntawm Secc Corrosion tsis kam?
"Scenario -} muaj tsawg" corrosion tsis kam: haum tsuas yog rau cov chaw pw hauv tsev. Kev ntub dej qhuav
"Kev Khom Nqi" corrosion tsis kam: vim nws nyias zinc txheej, corrosion kuj zoo rau kev ua (piv txwv li, passive, painting). Thaum siv ib leeg, nws corrosion tsis muaj zog yog tsis muaj zog tshaj li ntawm kub - dip galvanized khoom.
"Tus nqi - Performance tshuav nyiaj li cas suav nrog qhov chaw du, qhov txias} {rolled puag phaj), thiab tus nqi qis dua SGCC / GA. Nws yog qhov tsim nyog rau cov ntawv thov uas yuav tsum muaj cov tsos thiab muaj peev xwm tab sis muaj kev tiv taus qis condabion. Nws tsis tuaj yeem hloov kub - dip galvanized steel nyob rau hauv kev xeb ib puag ncig.
