Weathering steel, uas yog atmospheric corrosion kuj steel, yog nruab nrab ntawm cov hlau zoo tib yam thiab stainless hlau tsis tshua muaj alloy steel series, weathering steel yog ua los ntawm cov pa carbon steel ntxiv me me ntawm tooj liab, npib tsib xee thiab lwm yam corrosion resistant ntsiab lus, nrog zoo steel toughness, yas. extension, sib sau, vuam thiab txiav, abrasion, kub kub, qaug zog thiab lwm yam ntxwv;Huab cua tsis kam yog 2 ~ 8 npaug ntawm cov pa roj carbon zoo tib yam, txheej yog 1.5 ~ 10 npaug ntawm cov pa roj carbon zoo tib yam.Nyob rau tib lub sijhawm, nws muaj cov yam ntxwv ntawm xeb tsis kam, corrosion kuj, lub neej txuas ntxiv, thinning thiab noj txo, txuag zog thiab txuag hluav taws xob.

Cov khoom siv thiab cov yam ntxwv

Corten Steel originated los ntawm North America thiab yog dav siv nyob rau hauv zus tau tej cov railway carriages, ntim thiab choj.Weathering steel yog siv los ua cov khoom siv hauv tsev, hauv North America, Western Europe, Australia thiab Asia hauv Nyiv, Kaus Lim Qab Teb muaj keeb kwm yav dhau los.Ib txheej oxide tuab ntawm 50 ~ 100μm tuab nrog zoo adhesion rau cov hlau matrix yog tsim los ntawm cov xeb txheej thiab matrix hlau los ntawm kev ntxiv cov huab cua tiv taus cov ntsiab lus xws li tooj liab, chromium thiab npib tsib xee.Qhov tshwj xeeb ntom oxide txheej no muaj qhov ruaj khov thiab zoo li qub xim xim liab.1. Cov yam ntxwv ua tau zoo: Ua ntej ntawm tag nrho cov, nws muaj qhov pom kev zoo heev.Corroded steel phaj hloov raws sijhawm.Nws cov xim lightness thiab saturation yog siab dua li cov ntaub ntawv tsim kho, yog li nws yog ib qho yooj yim kom sawv tawm nyob rau hauv keeb kwm yav dhau ntawm vaj ntsuab nroj tsuag.Tsis tas li ntawd, qhov ntxhib nto tsim los ntawm corrosion ntawm steel phaj muab cov qauv kev nkag siab ntawm ntim thiab loj.2. Nws muaj peev xwm ua tau zoo.Zoo li lwm yam hlau, rusted steel daim hlau yog ib qho yooj yim los tsim rau hauv ntau yam duab thiab tswj kev ncaj ncees, uas ntoo, pob zeb thiab pob zeb ua tsis tau.3. Nws kuj muaj peev xwm sib txawv los txhais qhov chaw.Vim hais tias lub zog thiab toughness ntawm steel phaj yog loj heev, nws tsis yog ntau npaum li lub thickness txwv los ntawm cov qauv ntawm masonry khoom.Yog li ntawd, cov hlau nyias nyias tuaj yeem siv los cais qhov chaw kom meej meej thiab raug, ua rau qhov chaw ua kom pom tseeb thiab ci, tab sis kuj muaj zog.

Cov txheej txheem khoom thiab kev faib tawm

(teev huab cua ↑)

Cov txheej txheem kev kho xeb: xeb stabilization txoj kev kho yog nyob rau saum npoo ntawm huab cua tiv thaiv hlau, nrog rau cov txheej txheem tshuaj (xeb kua), yog li ntawd nws tsim xeb stabilization ntawm daim tawv nqaij zaj duab xis, yog ib yam ntawm inhibition ntawm kev siv cov hlau thaum ntxov. outflow ntawm xeb, kom lub stability., kev kho mob feem ntau 30 hnub.Feem ntau, yog tias qhov kev puas tsuaj hauv zos yog tshwm sim los ntawm kev kho cov txheej txheem dav dav, qhov tshwm sim ntawm tev xim yog tshwm sim los ntawm xeb, thiaj li ua kom lub ntsej muag pleev xim.Txawm li cas los xij, txoj kev kho xeb stabilization yog maj mam yaj daim tawv nqaij zaj duab xis, kom cov xeb ruaj khov, maj mam nthuav mus rau txhua qhov, npog ib txheej ntawm daim tawv nqaij zaj duab xis ntawm cov hlau, tsis muaj kev saib xyuas.1. Thawj theem: cov huab cua tiag tiag steel pib loj hlob me ntsis xeb me ntsis, cov xeb ntawm cov hlau zoo tib yam yog xoob, qee qhov kev kho xeb tsis zoo thiab txawm tias xeb ntawm daim tawv nqaij;3. Qhov thib ob theem ntawm xeb hlau phaj ntev: cov dej xeb ntawm cov huab cua tiag tiag yog tsawg dua, thiab qhov xeb hlau yog me dua thiab tuab;Cov dej xeb ntawm cov phaj hlau zoo tib yam yog ntau dua, thiab cov ntsiab lus xeb yog loj dua thiab nyias.Ordinary steel phaj xeb kem, kua muag cim yog qhov hnyav dua, hauv qab ntawm lub workpiece muaj cov cim dub;4. Qhov thib peb theem ntawm ntev xeb steel phaj: Qhov tseeb huab cua hlau muaj qhov tseeb thiab tuab cov xeb tseem ceeb rau cov txheej tiv thaiv.Nws yuav luag tsis yooj yim sua kom tshem tawm xeb los ntawm tes.Ordinary steel phaj xeb ntau dua, thiab txawm tias tag nrho cov khoom xeb xeb, xeb hnav.Cov huab cua tiag tiag steel yog beased rau reddish xim av, zoo tib yam steel phaj yog biased rau tsaus xim.

Kev tsim kho thiab kev teeb tsa ntawm cov nodes

Niaj hnub nimno weathering steel tsev kab hlau rhuav phab ntsa (3MM) thiab txhuas phaj sab nrauv phab ntsa installation zoo ib yam li tam sim no, tuab txheej (5MM thiab saum toj no) weathering steel phaj kab hlau rhuav phab ntsa txais chav tsev dai hom.Toj roob hauv pes thiab qee yam khoom siv yooj yim, feem ntau yog siv cov txheej txheem vuam ncaj qha.Ua tib zoo mloog cov hauv qab no: 1. Corrosion ntawm vuam cov ntsiab lus: oxidation tus nqi ntawm vuam cov ntsiab lus yuav tsum zoo ib yam li lwm yam ntaub ntawv, uas yuav tsum tau tshwj xeeb vuam cov ntaub ntawv thiab cov txheej txheem.2. Dej corrosion: weathering steel tsis yog stainless hlau, yog hais tias muaj dej nyob rau hauv lub concave ntawm cov weathering steel, tus nqi corrosion yuav sai dua, yog li nws yuav tsum tau ua ib txoj hauj lwm zoo ntawm cov kua.3. Cov huab cua ntsev ib puag ncig: weathering steel yog rhiab heev rau tej huab cua ntsev nyob rau hauv Hawaii.Nyob rau hauv ib puag ncig zoo li no, txheej txheej tiv thaiv yuav tsis tiv thaiv oxidation ntxiv hauv.4. Fading: Cov xeb txheej nyob rau saum npoo ntawm weathering steel tuaj yeem ua rau saum npoo ntawm cov khoom nyob ze nws ua xeb.
