1. Dab tsi yog lub corrosion resistance ntawm galvanized DX51d?
Kev Tiv Thaiv Kev Tiv Thaiv
Lub zinc txheej ua lub cev lub cev kom ncaj cais tawm ntawm cov roj corrosive (acid thiab alkali kev tawm tsam los ntawm tshwm sim {}}
Electrochemical kev tiv thaiv (kev tiv thaiv kev tua tsiaj)
Thaum lub zinc txheej puas lawm lossis tsis xws luag tshwm sim nyob rau saum npoo, yog qhov tsim muaj peev xwm ntawm cov hlau (corrote ua ntej
Passivation zaj duab xis tiv thaiv
Cov saum npoo ntawm zinc txheej yuav hnov qab nrog oxygen, carbon dioxide, thiab lwm yam txuas ntxiv zinc carbonate, uas txuas ntxiv mus qeeb zawv rau cov xeb uas muaj zog rau kev xeb.
2. Qhov tseeb dab tsi cuam tshuam rau kev corrosion tsis kam ntawm galvanized DX51d?
Zinc Txheej ceeb thawj: feem ntau qhia raws li "G / M²", tus loj dua tus nqi, qhov muaj zog dua corrosion tsis kam .
Vaum noo: Kev loj hlob ib puag ncig ib puag ncig (xws li chav dej, ntug dej hiav txwv corrosion, xav tau kev kho siab ntau dua
Cov pa paug piecutants: CLT), sulfide (so₂) {} {{1} {{1} {{1} {{1} {{1} {{1}
Qhov kub thiab txias: Qhov kub ib puag ncig yuav ua kom nrawm dua cov tshuaj lom neeg ntawm zinc txheej thiab cov kev cuam tshuam hauv nruab nrab, tab sis qhov cuam tshuam yog txwv ntawm chav tsev kub {}}}
{{0 {}} Dab tsi yog qhov zoo ntawm DX51D cov corrosion tsis kam?
Cov corrosion tawm tsam yog qhov zoo dua li cov khoom siv roj carbon tsawg, thiab tus nqi ua tau zoo yog high.
Cov txheej txheem tau paub tab, cov txheej zinc muaj zog muaj yooj yim rau poob tawm .
Lub zinc txheej thickness thiab nto kev kho mob tuaj yeem hloov kho kom haum rau cov sib txawv corrosion {}}
{{0 {}} Dab tsi yog qhov tsis zoo ntawm DX51D cov corrosion tsis kam?
Cov txheej zinc txheej muaj qhov tsawg tsawg thiab yuav ua corroded yog tias raug rau ib puag ncig corrosive heev rau ib lub sij hawm ntev .
Kev ua xws li txiav thiab vuam yuav puas tsuaj rau ntug zinc txheej (xws li zoo li kev pleev xim theem nrab thiab zinc ntxiv) .
5. Yuav ua li cas txhawm rau txhim kho lub corrosion tsis kam ntawm DX51D?
Xaiv cov txheej zinc zinc tuab raws li ib puag ncig: high corrosion scenarios muab qhov tseem ceeb rau tuab zinc txheej (xws li 275g / m²).
Cov tom qab kev kho mob: passivation los yog xim ua ntxiv rau lub neej .
Tom qab ua cov tshuaj tiv thaiv corrosion: zinc ntxiv lossis tiv thaiv xeb pleev xim rau ntawm txiav saum npoo thiab vuam cov ntsiab lus {}}
Kev tu ib txwm muaj: hauv cov av noo lossis kev coj tsis tu ncua ib puag ncig ntawm zinc txheej thiab kho qhov chaw uas zinc nyob rau hauv lub sij hawm .
