weathering steel khoom txheej txheem
Weathering steel, tseem hu ua COR-TEN® steel, yog ib hom hlau alloy uas tsim cov xim zoo li xeb ntawm nws qhov chaw thaum raug cov khoom. Cov txheej txheem no, hu ua weathering, muab cov hlau nrog cov txheej txheem tiv thaiv uas tiv thaiv corrosion ntxiv thiab deterioration. Hauv qab no yog cov txheej txheem ntawm kev tsim cov khoom siv huab cua steel:
1. Raw Material Selection: Cov khoom tseem ceeb ntawm weathering steel yog ib hom hlau hu ua low alloy lossis siab zog steel. Cov hlau no muaj cov ntsiab lus ntxiv xws li tooj liab, chromium, npib tsib xee, thiab phosphorus.
2. Kev tsim khoom: Cov khoom siv cua sov tuaj yeem tsim tau siv ntau yam kev tsim khoom xws li kub dov, txias dov, thiab forging. Cov txheej txheem no koom nrog shaping thiab tsim cov hlau mus rau qhov xav tau loj thiab cov duab.
3. Kev Kho Hniav: Thaum cov hlau tau tsim, cov txheej txheem xeb zoo li oxidized (patina) yuav pib tsim ib txwm dhau sijhawm. Txawm li cas los xij, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua kom nrawm, cov tuam txhab tuaj yeem siv ntau yam txuj ci xws li ntxuav cov kua qaub los yog abrasive blasting los tsim cov roughened nto uas txhawb kev tsim cov patina.
4. Kev Tswj Xyuas Zoo: Raws li nrog rau txhua yam khoom, kev tswj kom zoo yog qhov tseem ceeb los xyuas kom cov khoom ua tau raws li cov qauv tsim nyog. Weathering steel khoom tau dhau los ua cov kev ntsuam xyuas los xyuas kom meej tias lawv ua tau raws li qhov xav tau tshwj xeeb rau lub zog, kav ntev, thiab corrosion kuj.
5. Daim ntawv thov: Cov khoom siv cua sov yog feem ntau siv rau hauv cov khoom siv sab nraum zoov xws li txuas hniav, tsev, thiab duab puab. Qhov tshwj xeeb zoo li xeb zoo li cov hlau ntxiv rau qhov zoo nkauj ntawm cov qauv thaum muab cov txheej txheem tiv thaiv corrosion.
Hauv cov ntsiab lus, cov txheej txheem ntawm kev tsim cov khoom siv huab cua muaj xws li xaiv cov hlau zoo, tsim cov khoom, kho qhov chaw los txhawb kev tsim patina, ua cov kev tswj xyuas zoo thiab siv cov khoom rau sab nraum zoov.
