Qhov txiaj ntsig loj tshaj plaws ntawm kev xaiv SMA400BP Corten Steel rau cov qauv sab nraum zoov yog nws lub koob npe nrov rau qis- tu, ntev - ua haujlwm tau ntev - tab sis qhov no tsis txhais tau tias tsis muaj kev saib xyuas. Muaj ntawv pov thawj raws li JIS G 3114: 2022, qib no tso siab rau kev tsim kom ruaj khov, tus kheej - kho tooj liab-chromium patina kom xa tau 25+ xyoo ntawm kev tiv thaiv corrosion, thiab txawm tias me me kev saib xyuas tsis zoo tuaj yeem rhuav tshem cov txheej txheem tiv thaiv no, ua rau ua tsis tiav ntxov. Qhov xov xwm zoo yog tias SMA400BP cov kev xav tau ntawm kev saib xyuas yog qhov yooj yim, qis - tus nqi, thiab ua tiav nrog nws lub hom phiaj tsim JIS, tsis tas yuav muaj cov cuab yeej tshwj xeeb lossis kev kho dua tshiab.
Lub Sijhawm Teem Sijhawm Saib Xyuas (Environment{0}}Dependent)
Kev saib xyuas zaus thiab qhov dav yog ncaj qha mus rau cov qauv kev raug mob, raws li JIS G 3114: 2022 qhov kev ua haujlwm tau hais tseg rau SMA400BP:
Nyob deb nroog/tsawg- thaj chaw muaj kuab paug nyob hauv nroog (cov ntaub ntawv siv tau zoo): Kev kuaj pom ib xyoos ib zaug txaus. Tshawb xyuas qhov thaiv qhov dej, cov dej sawv ntsug, cov khoom khib nyiab, lossis cov cim qhia ntawm thaj chaw pitting. Tsis tas yuav tsum tau ntxuav, raws li cov ntaub ntawv patina thiab stabilizes ib txwm nyob hauv huab cua huv, qhuav.
Lub teeb hauv nroog / nruab nrab kev lag luam / qis- thaj chaw raug ntug hiav txwv (≥1km ntawm ntug dej): Ib nrab-txhua xyoo qis- tso dej tshiab yaug kom tshem cov ntsev, cov pa phem, thiab cov plua plav saum npoo av. Qhov no tiv thaiv cov kab mob los ntawm kev rhuav tshem cov patina qhov tsis sib xws, thaum tsis txhob muaj siab -lub siab ntxuav uas tuaj yeem tshem tawm cov txheej txheem tiv thaiv tsis paub qab hau.
Tsis yog -Kev Tiv Thaiv Kev Tiv Thaiv Kev Sib Tham
Cov kauj ruam tseem ceeb no tiv thaiv patina thiab tshem tawm cov feem ntau ua rau ua tsis tiav ntxov, ua raws li JIS G 3114: 2022 cov khoom tsim txwv:
Khaws qhov chaw kom tsis txhob muaj kev tiv thaiv mus tas li: Tsis txhob tso cov nplooj, av, cov ntaub ntawv yas, lossis cov khib nyiab carbon steel los zaum ntawm cov hlau mus ntev. Cov cuab yeej no ya raws thiab thaiv atmospheric raug, tiv thaiv patina los ntawm kev tsim thiab ua rau thaj tsam pitting corrosion.
Khaws cov dej tsis muaj kev cuam tshuam: Tshem tawm cov qhov dej thiab kho qhov chaw kom raug thaum txhua qhov kev tshuaj xyuas. JIS G 3114: 2022 tsis ntsuas SMA400BP rau kev tso dej tas mus li, thiab cov dej sawv ntsug yog tus tsav tsheb loj tshaj plaws ntawm kev nrawm nrawm rau cov xim tsis muaj Corten Steel.
Tshawb xyuas welds thiab tsim cov ntu txhua xyoo: Txheeb xyuas cov pob qij txha rau cov paib thaum ntxov ntawm pitting, thiab siv cov txhuam mos stainless hlau txhuam los ntxuav cov pob txha me me (tsis txhob txhuam cov roj carbon hlau, uas tawm cov hlau seem uas ua rau galvanic corrosion). Paub meej tias txias- cov seem tsim tsis muaj micro- tawg tuaj yeem nthuav dav thiab cuam tshuam rau patina.
Qhov Tseem Ceeb Saib Xyuas Qhov Ua Tsis Tau
Cov kev ua yuam kev no yuav ua rau tsis zoo rau SMA400BP qhov kev tiv thaiv corrosion, thiab yuav tsum tau zam nruj me ntsis:
Tsis txhob siv cov xim txheej txheem lossis txheej txheej, uas thaiv cov patina - txheej txheem tsim thiab ua kom nrawm dua corrosion thaum txheej txheej chips lossis tev.
Tsis txhob siv cov tshuaj tua kab mob acidic lossis alkaline, uas yuav ua rau cov tshuaj tiv thaiv patina thiab strip cov hlau alloy- nplua nuj txheej.
Tsis txhob zom lossis tawg qhov chaw tshwj tsis yog kho qhov chaw corrosion hnyav, vim qhov no tshem tawm cov tooj liab -chromium nplua nuj nto uas ua rau cov hlau tsis muaj corrosion.
Ntev -Lub Sij Hawm Kev Ncaj Ncees
Txhua 5 xyoos, ua ib qho kev tshuaj xyuas tag nrho kom haum nrog SMA400BP's 25+ xyoo tsim kev pab cuam lub neej:
Siv ultrasonic thickness kuaj xyuas kom paub tseeb tias tag nrho corrosion poob nyob rau hauv lub 1-1.5mm corrosion nyiaj tso cai teev nyob rau hauv koj JIS-tsim tsim.
Tshawb xyuas cov khoom thauj -cov kabmob rau cov cim qhia ntawm kev ntxhov siab tawg, tshwj xeeb tshaj yog nyob rau hauv cov qauv raug rau qee lub sijhawm khov.
Kho qhov chaw kho corrosion nrog weathering steel-matched vuam consumables, kom paub meej tias kho qhov chaw phim cov niam txiv steel qhov corrosion kuj.
Nyob rau hauv luv luv, unpainted SMA400BP Corten Steel muaj tsawg, ncaj nraim cov kev cai ntawm kev tiv thaiv nws JIS-txhais kev tiv thaiv patina. Raws li kev saib xyuas yooj yim, ua raws li cov lus qhia no, qib yuav xa nws cov lus cog tseg 25-35 xyoo kev pabcuam lub neej, nrog ib feem ntawm tus nqi thiab kev ua haujlwm yuav tsum tau ua kom muaj cov xim pleev xim rau carbon steel.
