Cov haujlwm tsim qauv xav tau cov ntaub ntawv sib npaug ntawm lub zog, ruaj khov, thiab kev ntseeg siab-tshwj xeeb tshaj yog rau sab nraum zoov lossis siab - siv cov ntawv thov. ASTM A242 Hom 1 Corten Steel yog qhov zoo- paub txog nws cov kev tiv thaiv corrosion, tab sis ntau tus neeg yuav khoom thiab cov kws tsim khoom xav paub: Puas yog nws muaj zog txaus rau kev siv cov qauv? Nws puas tuaj yeem tuav cov loads thiab kev ntxhov siab ntawm cov haujlwm ua haujlwm? Nws puas ua tau raws li cov qauv kev lag luam rau kev siv cov qauv? Lub ntsiab lus teb yog qhov tseeb:Yog lawm, ASTM A242 Hom 1 Corten Steel yog qhov tsim nyog rau feem ntau cov haujlwm ua haujlwm - nws cov khoom siv zog, kev tiv thaiv corrosion, thiab kev ua haujlwm ua rau nws txhim khu kev qha, qis- kev xaiv tu. Hauv qab no yog cov lus qhia yooj yim, cov tswv yim.
Vim li cas nws thiaj haum rau kev siv tus qauv (Key Strengths)
ASTM A242 Hom 1, tus qauv tsim los ntawm ASTM International, yog tsim los ua kom tau raws li cov qauv tsim, nrog rau ob qho tseem ceeb uas ua rau nws zoo tagnrho:
Mechanical Strength: Nws muaj qhov tsawg kawg nkaus tawm lub zog ntawm 345MPa thiab tensile lub zog ntawm 485MPa- cov txiaj ntsig no ua tau raws li qhov yuav tsum tau ua rau feem ntau lub teeb - rau - nruab nrab cov qauv loads, xws li railings, thav duab, thiab kev txhawb nqa.
Corrosion Resistance: Nws tus kheej- tsim kev tiv thaiv patina (los ntawm tooj liab, chromium, thiab npib tsib xee alloys) tiv thaiv xeb thiab degradation, kom ntseeg tau ntev - lub sij hawm kev ncaj ncees ntawm cov qauv - tseem ceeb heev rau sab nraum zoov structural tej yaam num uas fim lub ntsiab.
ASTM A242 Hom 1
Nws ua tau zoo hauv cov haujlwm ua haujlwm uas muaj kev tiv thaiv corrosion thiab lub zog nruab nrab yog qhov tseem ceeb - ntawm no yog cov feem ntau siv:
Lub teeb - mus rau - Cov Txheej Txheem Nruab Nrab: Sab nraum zoov railings, handrails, pergola thav duab, thiab lub teeb -lub luag hauj lwm txhawb- sib npaug zog thiab qhov hnyav rau kev yooj yim installation.
Architectural Structure Elements: Facade thav duab, cladding kev txhawb nqa, thiab cov qauv zoo nkauj zoo nkauj- sib txuas cov qauv kev ua haujlwm nrog kev zoo nkauj (nws patina ntxiv ib qho rustic, muaj kev zoo nkauj).
Sab nraum zoov Cov Qauv Ua Haujlwm: Chaw ua si vaj tse, cov neeg taug kev txuas hniav (railings thiab teeb ncej), thiab kev lag luam taug kev- tiv thaiv huab cua puas yam tsis muaj kev saib xyuas ntau zaus.
Thaum twg los zam nws rau kev siv tus qauv
Txawm hais tias nws tsim nyog rau feem ntau cov haujlwm ua haujlwm, nws tsis zoo rau qhov hnyav hnyav - cov xwm txheej:
Hnyav-Lub luag haujlwm thauj khoom: Cov kab hlau loj loj, siab- nce lub tsev thav duab, lossis kev txhawb nqa kev lag luam uas xav tau lub zog siab tshaj 345MPa- xaiv cov ntsuas tuab lossis siab dua- qib Corten (xws li A588 Qib B) hloov.
Huab cua txias heev: Hauv cov cheeb tsam uas muaj qhov kub thiab txias qis dua -10℃/-14℉, nws lub zog tuaj yeem txo qis-opt rau A588 Qib B (nruj mus txog -20 degree) rau kev nyab xeeb ntawm cov qauv.
Tswv yim tswv yim rau kev siv tus qauv
Ua kom nws qhov kev ua tau zoo tshaj plaws hauv cov haujlwm ua haujlwm nrog cov kauj ruam yooj yim no:
Xaiv qhov tuab tuab: 8mm-30mm rau cov khoom siv (thicker rau hnyav dua) kom muaj zog thiab ruaj khov.
Siv Corten- sib xws vuam electrodes: Tswj lub zog thiab corrosion kuj ntawm cov pob qij txha (xws li, E7018 electrodes).
Cia lub patina tsim ib txwm: Tsis txhob pleev xim, vim nws ntxiab ya raws thiab tuaj yeem ua rau cov hlau tsis muaj zog rau lub sijhawm ntev.
Hauv luv luv, ASTM A242 Hom 1 Corten Steel yog qhov kev xaiv txhim khu kev qha rau feem ntau cov haujlwm ua haujlwm. Nws lub zog, kev tiv thaiv corrosion, thiab kev saib xyuas qis ua rau nws siv tau rau lub teeb - mus rau - nruab nrab siv cov qauv- zoo meej rau kev ntsuas kev ua tau zoo thiab tus nqi.
