Dab tsi yog weathering steel?
Ntau tus neeg tsim khoom xaiv cov khoom siv no vim nws cov kav ntev thiab ductility. Weathering steel yog ib qho qis - carbon hlau uas muaj alloying ntsiab xws li npib tsib xee thiab tooj liab, uas muab nws superior zog thiab corrosion kuj. Tsis tas li ntawd, nws yog kev lag luam ntau dua li lwm cov ntaub ntawv xws li galvanized steel. Tau kawg, cov khoom siv no tsis haum rau txhua qhov haujlwm lossis qhov chaw.
Kev txiav txim siab rau Weathering Steel
Qhov zoo ntawm Huab cua
Qhov tseem ceeb tshaj plaws yam ntxwv ntawm weathering steel yog nws superior corrosion kuj. Qhov no yog vim li cas nws yog ib qho khoom siv rau cov hlau txuas hniav thiab cov tsev. Weathering steel undergoes tus txheej txheem hu ua "kev zoo corrosion." Tsis zoo li lwm cov qauv hlau uas xeb tuaj yeem ua rau muaj teeb meem lossis txawm tias muaj kev phom sij, xeb ntawm huab cua steel tiv thaiv cov khoom los ntawm kev puas tsuaj ntxiv. Xeb tsuas yog tsim rau ntawm txheej txheej ntawm cov hlau thiab nws thiaj li hloov mus rau hauv kev tiv thaiv kev tiv thaiv, txhim kho nws cov kev tiv thaiv rau yav tom ntej corrosion.
Tsis tas li ntawd, cov khoom siv no yuav luag tsis muaj kev saib xyuas, uas muaj txiaj ntsig zoo tsis yog nyob rau hauv cov chaw nyob deb nroog lossis tsis tuaj yeem siv tau, tab sis kuj txuag nyiaj hauv lub sijhawm ntev. Cov kev tshawb fawb qhia tau hais tias huab cua steel tuaj yeem kav ntev mus rau kaum xyoo nrog kev saib xyuas tsawg. Thiab vim hais tias kev kho yog feem ntau yooj yim, cov choj no raug nqi tsawg dua lawv lub neej tshaj li cov khoom tsim nrog lwm cov ntaub ntawv.
Tsis tas li ntawd, cov qauv no tsis tas yuav tsum tau pleev xim, muab kev tiv thaiv thiab kev zoo nkauj. Ntau tus neeg pom cov cim ua xeb ntawm cov khoom siv no txaus nyiam thiab tseem pab kom tsis txhob tso cov organic sib txuas (VOCs) los ntawm cov xim pleev xim.
Lub Drawbacks ntawm Huab Cua
Thaum huab cua steel suab zoo tagnrho, ntau yam yuav tsum tau xav txog ua ntej kev tsim kho. Tej huab cua thiab huab cua tej yam kev mob yuav ua rau muaj teeb meem nrog durability thiab corrosion kuj. Piv txwv li, huab cua hlau yuav tsum tsis txhob tsim nyob rau hauv siab -chlorine ib puag ncig.
Tsis tas li ntawd, nws ua tau zoo tshaj plaws hauv kev hloov pauv ntub thiab qhuav ib puag ncig ncig. Yog hais tias ib puag ncig tsis tu ncua, xws li thaum submerged hauv dej los yog faus hauv av, cov hlau muaj peev xwm tiv thaiv corrosion yuav txo qis.
Txawm hais tias muaj coob tus txaus siab rau nws cov xeb hauv ntuj -zoo li qhov ci, nws tuaj yeem yooj yim stain cov tsev nyob ze; yog li ntawd, nws yog qhov zoo tshaj kom nws deb ntawm cov pob zeb lossis lwm yam khoom uas yooj yim nyiam stains.
