Thaum koj teev Corten Steel rau cov qauv sab nraum zoov, tus lej tseem ceeb tshaj plaws rau kev kwv yees nws lub neej kev pabcuam yog nws tus nqi corrosion. Rau SMA400BP Corten Steel, tau lees paub los ntawm JIS G 3114: 2022, tus nqi no tsis yog kev thov lag luam tsis meej- nws yog ib qho kev cai nruj me ntsis, ib puag ncig- nyob ntawm tus qauv ntsuas uas tso cai rau koj kom suav cov qauv tuab, pob nyiaj siv rau kev saib xyuas, thiab lav ntau xyoo ntawm kev ua tau zoo. Tsis zoo li cov pa roj carbon zoo tib yam, uas corrodes sai thiab unpredictably, SMA400BP tus nqi corrosion stabilizes lub sij hawm, tsav los ntawm nws JIS-mandated alloy muaj pes tsawg leeg, kom xa ib yam, ntev -lub sij hawm tus nqi rau daim ntawv thov kev sib raug zoo.
JIS-Defined Foundation ntawm Nws Tsawg Corrosion Rate
SMA400BP qhov kev ua tau zoo ntawm kev txhim kho corrosion pib nrog nws cov tshuaj pleev kom nruj, tau teev tseg hauv JIS G 3114: 2022. Nws cov core corrosion- sib ntaus sib tua alloys yog 0.30-0.50% tooj liab thiab 0.45-0.75% chromium, uas hnov mob nrog oxygen thiab noo noo los tsim ib tug ntom, nws tus kheej- kho patina. Cov txheej txheem oxide adherent no ua raws li qhov cuam tshuam mus tas li, thaiv kev nkag mus ntxiv ntawm cov ntsiab lus corrosive thiab ua kom qeeb corrosion rau ib feem ntawm tus nqi pom hauv cov pa roj carbon tsis zoo.
Raws li JIS cov qauv, SMA400BP xa5-10x tus nqi qis dua li cov pa roj carbon zoo tib yamnyob rau hauv ib puag ncig zoo atmospheric, tsis tas yuav muaj kev tiv thaiv xim lossis txheej txheej.
SMA400BP's Corrosion Rate los ntawm Ib puag ncig (JIS-Cov ntaub ntawv sib luag)
Corrosion tus nqi ( ntsuas hauv mm / xyoo) sib txawv ncaj qha nrog cov xwm txheej raug, thiab JIS G 3114: 2022 txhais cov kev ua tau zoo ciam teb rau SMA400BP. Hauv qab no yog nws qhov tiag - ntiaj teb no, tus qauv- thim rov qab corrosion tus nqi rau feem ntau qhov project ib puag ncig, ua ke nrog 25-xyoo tag nrho corrosion poob los ua kom yooj yim rau kev pab cuam lub neej:
Cov neeg nyob deb nroog & qis-Cov pa phem Suburban ib puag ncigJIS Baseline Rate: 0.01–0.03 mm/year25-Year Tag Nrho Corrosion: 0.25–0.75 mmQhov no yog qib qib qhov zoo tshaj plaws ib puag ncig, qhov twg patina tsim tag nrho thiab nyob ruaj khov. Nws yog qhov zoo tshaj plaws rau kev tsim kho vaj tse nyob deb nroog, toj roob hauv pes vaj tse, thiab qis-siab suburban tsev framing.
Lub Teeb Nroog & Nruab Nrab Industrial Ib puag ncigJIS Baseline Rate: 0.03–0.05 mm/year25-Xyoo Tag Nrho Corrosion: 0.75–1.25 mmMild nroog tsheb emissions lossis qis- theem muaj kuab paug me ntsis ua kom corrosion, tab sis tooj liab-chromium patina tseem muaj kev tiv thaiv txhim khu kev qha. Qhov no ua rau qib tsim nyog rau lub nroog cov neeg taug kev txuas hniav, railings, thiab lub teeb muaj lub tsev sab nrauv.
Tsawg-Kom ntug hiav txwv raug (Ntau dua lossis sib npaug li 1km ntawm ntug dej hiav txwv)JIS Baseline Rate: 0.03–0.06 mm/year25-Year Tag Nrho Corrosion: 0.75–1.5 mmSalt-laden av noo yam tsis muaj ntsev tsuag ncaj qha ua rau me ntsis nce corrosion. JIS G 3114: 2022 tsis pom zoo rau SMA400BP rau cov cheeb tsam loj ntawm ntug dej hiav txwv nyob rau hauv 500m ntawm ntug dej hiav txwv, qhov twg cov tshuaj ntsev ncaj qha thawb tus nqi corrosion siab tshaj 0.08 hli / xyoo thiab rhuav tshem cov patina.
Cov kauj ruam siv tau los txo SMA400BP tus nqi Corrosion
Thaum JIS cov qauv lees paub qhov kev ua tau zoo, cov kauj ruam yooj yim, ua tau zoo tuaj yeem ua kom ruaj khov rau patina thiab qis dua - lub sij hawm corrosion:
Ntxuav cov hlau saum npoo ua ntej kev teeb tsa kom tshem tawm cov nplai zeb, roj, thiab cov pa roj carbon hlau seem, uas tuaj yeem ua rau tsis sib xws patina tsim thiab hauv zos pitting.
Tsim cov qauv nrog cov kua dej kom raug tshem tawm cov dej sawv ntsug, uas sib xyaw nrog cov pa phem kom nrawm dua corrosion.
Siv cov huab cua huab cua- cov khoom siv vuam sib txuas kom ntseeg tau tias cov welds muaj qhov corrosion kuj zoo ib yam li cov niam txiv steel, tsis txhob muaj qhov kub siab - corrosion hotspots.
Ua ib nrab- dej tshiab txhua xyoo yaug hauv cov ntug dej hiav txwv lossis thaj chaw muaj kev lag luam kom tshem tawm cov ntsev los yog cov pa phem tsim thiab khaws cov patina.
Hauv luv luv, SMA400BP Corten Steel muab JIS- txheeb xyuas qhov corrosion ntawm 0.01–0.06 hli / xyoo hauv nws qhov zoo tagnrho cov huab cua puag ncig. Nws ruaj khov, tsis tshua muaj corrosion kuj tshem tawm ntau zaus repainting, txiav cov nqi lifecycle, thiab muab kwv yees 25+ xyoo kev pab cuam lub neej rau lub teeb- rau- nruab nrab load sab nraum zoov qauv raws li nws JIS G 3114:2022 tsim lub hom phiaj.
