Nyob rau hauv xyoo tas los no, weathering steel tau siv ntau thiab ntau dua los ua cov khoom siv tau zoo rau kev ua vaj tsev thiab kev lag luam kev tsim kho vaj tse. Vim hais tias nws yog ib tug weathering hlau, nws muaj ib tug tiv thaiv patina uas yog resistant rau corrosion, muab nws ntau yam kev siv thiab ib tug txaus nyiam aesthetic zoo.

Lawm, tau muaj kev txaus siab nyob rau hauv weathering steel thiab weathering steel. Thaum cov kev txhawj xeeb no tsis muaj tseeb, txwv tsis pub huab cua corrosion - uas peb yuav tau mus rau tom qab - cov khoom siv hluav taws xob ntawm corT-Ten steel alloys ua cov khoom zoo rau cov nroj tsuag loj hlob hauv feem ntau huab cua.

Hauv kab lus no, peb yuav tham txog lub ntsiab lus no. Peb mam li tham txog dab tsi weathering steel yog, thiab xeb thiab corrosion. Tom qab ntawd peb yuav tham txog huab cua kev cog qoob loo steel thiab kev coj ua zoo tshaj plaws cuam tshuam nrog nws. Yog li yog tias koj xav paub seb huab cua hlau puas yog rau koj, nyeem cov lus no!

Dab tsi yog weathering steel?

Weathering steel yog chromium-tooj ​​liab alloy weathering steel, uas tso siab rau kev ntub dej thiab ziab kom tsim kom muaj txheej tiv thaiv xeb. Thaum lub sij hawm, nws hloov xim, pib nrog ib tug txiv kab ntxwv-liab xim thiab xaus nrog ib tug purplish patina. Thaum cov neeg feem coob muaj kev sib raug zoo nrog cov xeb, qhov no yog lub sij hawm yuav tsum tau tsim kom muaj qhov tseeb tsos thiab foob, tsim ib txheej los tiv thaiv cov khoom seem ntawm corrosion. Qhov tseeb, weathering steel yog heev resistant rau corrosion thiab tau siv nyob rau hauv nto moo tsim tej yaam num xws li tshaj tawm ntauwd nyob rau hauv Leeds, UK.

Colton ASTM daim ntawv pov thawj

Tus thawj CORT-Ten A tau txais American Institute of Testing and Materials standard designation for low alloy, high strength, and high corrosion resistance. ASTM qib tshiab rau Weathering steel B muaj cov khoom zoo ib yam, tab sis tau txais cov qauv tsim los qhia tias nws tuaj yeem tsim thiab siv rau cov ntawv. Cov hlau uas ua rau huab cua huab cua yog tooj liab, chromium, manganese thiab npib tsib xee.

Qhov sib txawv ntawm Corten thiab Redcor

Ib qho kev sib txuas tsim nyog piav qhia yog qhov sib txawv ntawm huab cua steel thiab hlau liab. Pob kws - Kaum yog kub-kuav los tiag steel alloy siv nyob rau hauv railway thiab shipping industries. Liab hlau yog cov huab cua huab cua, tab sis nws yog txias dov es tsis kub dov. Qhov txias yob no pab tswj cov tshuaj muaj pes tsawg leeg ntawm daim ntawv sib sau, ua kom nws zoo ib yam ntawm cov khoom.

Qhov sib txawv ntawm weathering steel A thiab weathering steel B

Wb kuj tham txog qhov sib txawv ntawm weathering steel A thiab weathering steel B. Lawv yog cov tseem ceeb tib yam khoom, tab sis weathering steel A, los yog cov thawj weathering steel -TEN, tau ntxiv phosphorus los ua kom muaj txiaj ntsig zoo hauv tsev facades thiab pa taws. Weathering STEEL B yog cov hlau tsis muaj huab cua, tsis muaj qhov ntxiv no, tsim nyog rau cov qauv loj. Muaj lwm yam hloov maj mam hloov ntawm cov tshuaj muaj pes tsawg leeg ntawm ob corten steels, tab sis nws yog tsim nyog sau cia tias corten A tsis tau siv nyob rau hauv txoj kev loj hlob ntawm lub Bodie Corten planter.



Ib feem nthuav ntawm txoj kev loj hlob ntawm cov nroj tsuag no yog tias lawv tuaj yeem loj hlob zaub mov kom zoo. Hlau oxide tso rau hauv cov av thaum lub sij hawm xeb yog tsis muaj tshuaj lom thiab yuav tsis cuam tshuam rau cov nroj tsuag
