Thaum npaj hnyav- cov qauv ua haujlwm, tus thawj tswj hwm qhov project thiab cov neeg yuav khoom feem ntau sib npaug ob yam tseem ceeb: kev ua haujlwm thiab tus nqi. Hnyav- cov haujlwm ua haujlwm xav tau lub zog siab thiab ua haujlwm ntev, tab sis ntau tus txhawj xeeb tias xaiv cov khoom siv siab - lub zog zoo li Q460NH Corten Steel yuav thawb cov peev nyiaj dhau mus. Raws li qhov siab - huab cua muaj zog- cov hlau tsis muaj zog, Q460NH yog tsim los rau cov khoom hnyav -tab sis nws puas yog tus nqi tiag tiag - zoo dua piv rau lwm txoj hauv kev? Lub ntsiab lus teb yog qhov tseeb:Yog lawm, Q460NH Corten Steel yog tus nqi siab heev - siv tau rau cov qauv hnyav -, vim nws cov nqi qis dua, kev saib xyuas tsawg, thiab lub neej ua haujlwm ntev offset cov nuj nqis zoo dua li ntau lwm txoj hauv kev. Hauv qab no yog cov lus qhia yooj yim, ua tau zoo.
Vim li cas Q460NH Txuag Tus Nqi (3 Qhov Zoo Tshaj Plaws)
Q460NH tus nqi-kev ua tau zoo tsis yog hais txog tus nqi qis ua ntej xwb- nws yog hais txog lub sijhawm ntev- tus nqi, tsis muaj kev cuam tshuam rau hnyav- lub luag haujlwm ua haujlwm:
Tus nqi qis dua: Muab piv rau cov hlau tsis muaj steel (304/316L) thiab tshwj xeeb siab - lub zog steels, Q460NH yog 30-50% pheej yig dua, txuag nyiaj ntau rau cov haujlwm loj- nplai hnyav (piv txwv li, kev txhawb nqa choj, kev lag luam thav duab).
Tus nqi tu tsawg kawg nkaus: Nws Corten patina muab natural corrosion kuj, tshem tawm qhov xav tau ntawm kev pleev xim ntau zaus, txheej, lossis kho dua -txuag tus nqi tu txhua xyoo (txog 70% tsawg dua cov pa roj carbon tsis zoo).
Lub neej ua haujlwm ntev: Nrog rau kev siv kom zoo, Q460NH kav ntev 20-30+ xyoo nyob rau hauv hnyav- cov xwm txheej, zam kev hloov pauv uas muaj nqi qis dua - qib, tsis tshua muaj steel hlau.
Tus nqi -Kev sib piv muaj txiaj ntsig (Q460NH vs. Cov Kev Xaiv Zoo Tshaj)
Txhawm rau pom nws tus nqi kom meej, ntawm no yog ib qho yooj yim sib piv rau hnyav- cov qauv ua haujlwm (tsom rau tag nrho cov nqi tshaj 10 xyoo):
Q460NH Corten Steel: Tus nqi qis dua + tsis muaj kev saib xyuas=tus nqi qis tshaj plaws; khaws lub zog siab (yield Ntau dua lossis sib npaug ntawm 460MPa) rau cov khoom hnyav.
Stainless hlau (304): Tus nqi siab tshaj + kev saib xyuas tsawg kawg=2-3x tus nqi siab dua; overkill rau feem ntau hnyav- cov haujlwm ua haujlwm (lub zog qis dua Q460NH).
Ordinary Carbon Steel: Tus nqi qis tshaj plaws + kev saib xyuas siab (thaum pleev xim / txheej)=tag nrho cov nqi zoo ib yam li Q460NH; Lub neej ua haujlwm luv dua (10-15 xyoos) thiab qis zog.
Qhov zoo tshaj plaws Hnyav-Lub luag haujlwm Scenarios rau Q460NH tus nqi-Kev ua tau zoo
Q460NH tus nqi ci ci tshaj plaws nyob rau hauv cov hnyav no -cov dej num siv, ua kom txuag tau nyiaj ntau tshaj:
Loj sab nraum zoov hnyav qauv: Choj kev txhawb nqa, kev loj guardrails, thiab industrial platform thav ntawv (cov khoom ntim siab, tsis tshua muaj kev saib xyuas).
Tsawg-kev tu cov khoom hnyav: Cov khoom siv hauv paus, cov khoom khib nyiab, thiab lub Hoobkas tsim cov trusses (tsis tu ncua los yog kho).
Me me-rau- ib puag ncig corrosive nruab nrab: Nroog / suburban hnyav- cov dej num ua haujlwm (tsis txhob muaj nqi tiv thaiv corrosion ntxiv).
Tswv yim tswv yim los txhawb tus nqi -Kev ua tau zoo
Tau txais txiaj ntsig ntau dua los ntawm Q460NH nrog cov kauj ruam yooj yim no:
Xaiv cov qauv tuab (16-60mm): Cov qauv ntau thiab tsawg tsis muaj qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis (MOQ) thiab luv luv lub sij hawm, txiav cov nqi yuav khoom.
Optimize thickness xaiv: Siv cov phaj nyias (vs. qis dua- qib steel) rau tib lub load (ua tsaug rau Q460NH lub zog siab), txo cov khoom siv.
Txhawb kev tsim patina ntuj: Tsis txhob muaj cov txheej txheem tsis tsim nyog- cia cov patina tsim ib txwm ua kom txuag tau cov nqi tu.
Thaum Q460NH yuav tsis yog qhov pheej yig tshaj (tab sis tseem muaj nqis)
Nyob rau hauv qhov hnyav corrosive ib puag ncig (xws li, thaj chaw ntug dej hiav txwv ＜1km ntawm ntug dej), Q460NH yuav xav tau kev tiv thaiv ntxiv (hloov txhua hli), tab sis nws tseem pheej yig dua li cov hlau tsis muaj steel. Rau qhov siab heev -siab hnyav- cov haujlwm ua haujlwm, cov hlau tshwj xeeb yog xav tau-tab sis cov no tsis tshua muaj thiab kim dua.
Hauv luv luv, Q460NH Corten Steel yog tus nqi tshaj plaws - kev xaiv zoo rau feem ntau hnyav - cov qauv ua haujlwm. Nws sib npaug tus nqi qis dua, kev saib xyuas tsawg, thiab lub neej ua haujlwm ntev, xa tus nqi ntau dua li lwm txoj hauv kev thaum ua tau raws li qhov siab - lub zog xav tau ntawm cov khoom hnyav.
