Lub hauv paus ntsiab lus ntawm S355JOW weathering steel:
Ntxiv ib qho ntawm cov ntsiab lus alloying hauv cov hlau, xws li P, Cu, Cr, Ni, Mo, txhawm rau txhawm rau txhawm rau tiv thaiv huab cua corrosion, nyob rau hauv kev cuam tshuam ntawm huab cua puag, nyob rau hauv lub hauv paus hlau nyob rau hauv lub cim ntawm kev tiv thaiv tsis siv neeg. ntawm oxides, thiaj li hais tias lub nto ntawm cov hlau los tsim ib tug ntom thiab muaj zog adhesion rau cov zaj duab xis tiv thaiv, hindering lub xeb mus rau lub diffusion thiab kev loj hlob ntawm kev tiv thaiv ntawm xeb txheej ntawm lub substrate hauv qab no, nyob rau hauv thiaj li yuav qeeb tus nqi ntawm cov oxides. nws corrosion. Nyob rau hauv cov xeb txheej thiab cov substrate ntawm qhov tsim ntawm li 50μm ~ 100μm tuab amorphous spinel-type oxide txheej tuab thiab zoo adhesion nrog lub hauv paus hlau, vim muaj nyob ntawm no txheej ntawm ntom oxide zaj duab xis, tiv thaiv lub atmospheric oxygen thiab dej. cov hlau substrate nkag mus, qeeb qeeb ntawm txoj kev loj hlob ntawm rusted steel cov ntaub ntawv, zoo heev txhim kho atmospheric corrosion kuj ntawm steel cov ntaub ntawv. Weathering steel tuaj yeem siv thinning, siv tau los yog ua kom yooj yim rau txheej txheej, thiab ua rau cov txheej txheem ntawm kev tiv thaiv corrosion lub neej txuas ntxiv, kev txuag hluav taws xob thiab kev txo qis, kev kho dua tshiab ntawm cov hlau, tab sis kuj muaj cov hlau niaj hnub tuaj yeem ua ke rau hauv cov txheej txheem tshiab, cov cuab yeej tshiab. , tshiab technology thiab ua rau nws sustainable kev loj hlob thiab innovation ntawm cov hlau.
