Cov laj thawj tseem ceeb rau kev ua kom haum hauv qhov chaw noo
Alloy Compinition Combles Tiv Thaiv Patina: S355555555555555555555555555555555555555555555555 cov ntsiab lus xws li tooj liab (Cu), cov tshuaj chromium (p), thiab cov pa roj oxygen, thiab carbon dioxide hauv huab cua. Cov tshuaj tiv thaiv no ua cov tuab tuab, cov txheej oxide txheej (patina) saum npoo.
Patina blocks ntxiv corrosion: Muaj ib zaug patina stabilizes (feem ntau nyob rau hauv ob peb hlis hauv damp yam xwm txheej), nws ua raws li lub cev lub cev. Nws tiv thaiv kev ya raws thiab cov tshuaj uas muaj xeb ntawm cov hlau hauv qab, ua kom qeeb qeeb qeeb ntawm cov pa roj carbon hlau.
Ua raws li cov qauv hluav taws xob hlau: As per European standard EN 10025-5, S355J0WP is classified as a "atmospheric corrosion-resistant structural steel." Damp ib puag ncig, thaj chaw los nag, cov kev ua haujlwm maj mam qhuav, lossis npog sab nraum zoov) poob rau hauv nws cov kev pabcuam tsim qauv.
Sau ntawv rau kev siv hauv cov chaw noo
Zam kev tawm dag zog tas mus li: S355555555555555555555555555555555555555555555555555555555555555555555555555555555555g "(ntu ntub dej lossis siab}}}}} eg, underwater teeb). Kev immersion mus tas li tuaj yeem tiv thaiv lub patina los ntawm stabilizing thiab nrawm hauv kev ua kom huv.
Xyuas kom muaj qhov chaw tso pa tawm: Hauv cov chaw ntub dej (piv txwv li, sab hauv tsev qhuav chav), ua kom muaj kev tiv thaiv kom zoo. Stagnant noo yuav ncua sij hawm pata tsim lossis ua rau muaj kev hws saum npoo av, uas tuaj yeem raug kev sib tw ntawm huab cua ncig.
Pib Saib Xyuas: Ua ntej siv, tshem tawm cov roj, av, lossis cov yeeb yaj kiab tiv thaiv ib ntus ntawm cov hlau deg. Qhov no ua kom cov alloy cov khoom tawm tsam tusyees nrog ib puag ncig ua ib qho kev sib dhos patina.
