Qhov zoo tshaj plaws corrosion Desistance Kev ua tau zoo ntawm SMA400W WUNCKSAL STEEL STEEL hauv ntau qhov chaw
SMA400AW, ib qho kev ua tau zoo ntawm cov huab cua zoo sib xws nrogJIS G3114, muab cov dej siab tshaj plaws tsis kam ntawm cov huab cua txog cov huab cua vim nws tshwj xeeb tagnrho muaj pes tsawg leeg (muajCU, CR, NI, thiab p). Tus txheej txheem steel no yog tsim kom muaj tuab, tus kheej tiv thaiv oxide txheej (patina) thaum raug rau huab cua, qeeb qeeb qeeb ntxiv corrosion. Hauv qab no yog cov ncauj lus kom ntxaws tshuaj xyuas ntawm nws txoj kev ua tau zoo thoob plaws ib puag ncig:
1. Qhov kev ua yeeb yam zoo tshaj plaws
Inland Urban / Nyob deb nroog Urmospheres
SMA400aw excels hauvQhib-huab cua ib puag ncigNrog rau kev ua kom qhuav / ntub dej ntub, xws li Urban thiab nyob deb nroog chaw. Lub Patina ruaj khov ruaj khov uas ua rau cov xwm txheej no muab kev tiv thaiv ntev, muab2-6 lub sij hawm ntau dua corrosion tsis kamPiv rau cov pa roj carbon hlau (piv txwv li, SS400).
Teeb meem muaj teeb meem
Cov hlau cov khoom sib dhos (tshwj xeebCu thiab CR) txhim kho kom tsis kam rauacid los nag thiab cov kuab lom me me, ua rau nws haum rau cov ntawv thov cov kev thov hauv cheeb tsam nrog kev tswj kev muaj kuab.
Huab cua huab cua
Ib puag ncig nrogKev txhawj xeeb ntawm cov av noo thiab kev hloov caij nyoog(xws li, Nyiv, Northern Europe, thiab ntu ntawm North America) yog qhov zoo tshaj plaws, raws li lub patina tsim cov dej noo tsis muaj ntau dhau kev ua haujlwm tsis zoo.
2. Txais tau tab sis suboptimal cov xwm txheej
Vaum huab meem
Thaum sma400aw tuaj yeem ua hauv cov cheeb tsam muaj av noo (piv txwv li, Southeast Asia),Lub caij nyoog ntubTej zaum yuav ncua chanina stabilization. Tsim nyog drosage druct yog qhov tseem ceeb kom tsis txhob muaj kev xeb hauv zos.
Lub teeb pom kev ntawm ntug hiav txwv
Hauv cov cheeb tsam5-10 km landland los ntawm ntug hiav txwv, qhov twg ntsev tsuag yog tsawg heev, SMA400W tseem tuaj yeem ua tau zoo nrog kev txij nkawm me. Txawm li cas los xij, nws txoj kev corrosion yuav siab dua nyob rau hauv ib puag ncig ib puag ncig.
3. Cov chaw tsis tsim nyog
Tubrogrog / Nqaum Thaj Av
Chloride-nplua nuj cua(piv txwv li, tsis pub dhau 1 km ntawm seawater) accelerates pitting thiab undermines lub patina. Rau cov chaw ntawd,Stainless hlau lossis pleev xim rau cov hlauPom zoo.
Tshuaj lom neeg-txhim kho chaw muaj teeb meem
Kev nphav raug rauCov kev sib txuas lus siab ntawm cov neeg leej faj (h₂s) lossis de-icing ntsevtuaj yeem txwv cov txheej tiv thaiv, ua rau kev ua tsis tiav thaum ntxov.
4. Txhim kho kev ua haujlwm hauv cov xwm txheej nyuaj
Yog tias SMA400W yuav tsum tau siv nyob rau hauv suboptimal ib puag ncig, xav txog:
Tsim qauv(piv txwv li, sloped nthwv dej rau cov dej ntws tawm, kev zam ntawm cov crevices).
Ib ntus txheejThaum lub sijhawm thawj zaug PATINE tsim lub sijhawm (1-3 xyoos).
Alloy hloov kho tshiab(xws li, sma490aw rau lub zog siab dua thiab marginalally zoo corrosion tsis kam).
