Cov ntaub ntawv sab nraum zoov ntsib qhov raug los nag, av noo, qhov kub thiab txias hloov, thiab txawm tias ntsev los yog kuab paug - tsis zoo corrosion kuj ua rau xeb ntxov ntxov, kev puas tsuaj ntawm cov qauv, thiab kev hloov tsis tu ncua. Q355GNH Corten Steel tau dav siv rau cov haujlwm sab nraum zoov, tab sis ntau tus neeg yuav khoom tseem xav tsis thoob tias nws qhov kev tiv thaiv corrosion tuav tau li cas hauv - ntiaj teb sab nraum zoov. Tsis zoo li cov hlau zoo tib yam uas xeb sai sai sab nraum zoov, Q355GNH yog tsim los rau huab cua tsis kam, tab sis nws qhov kev ua tau zoo sib txawv ntawm ib puag ncig. Yog li, Q355GNH tiv thaiv corrosion sab nraum zoov zoo li cas, thiab dab tsi cuam tshuam rau nws cov kav ntev? Raws li kev sim teb thiab cov qauv siv, cov lus teb tseem ceeb yog qhov tseeb:Q355GNH muab kev tiv thaiv corrosion zoo rau sab nraum zoov, tsim kev tiv thaiv patina ruaj khov uas ua tau zoo tshaj cov hlau zoo tib yam - nrog kev ua tau zoo nyob thoob plaws ntau qhov chaw sab nraum zoov, los ntawm cov cheeb tsam me me mus rau thaj chaw ntub lossis txias.. Hauv qab no yog cov lus qhia yooj yim, ua tau zoo.
Qhov zais cia rau Q355GNH sab nraum zoov Corrosion Resistance: Patina Tsim
Q355GNH lub peev xwm los tiv thaiv sab nraum zoov corrosion nyob rau hauv nws lub ntuj patina - ib txheej tuab, adherent txheej uas ua dhau sij hawm, tsis xav tau coatings ntxiv:
Nws Ua Haujlwm Li Cas: Q355GNH muaj cov khoom siv hlau (Cu, Cr, thiab kab Ni) uas hnov mob nrog oxygen thiab ya raws hauv huab cua. Cov tshuaj tiv thaiv no tsim ib txheej nyias, ruaj khov patina uas thaiv kev sib txuas ntxiv ntawm cov hlau substrate thiab cov khoom corrosive.
Patina Sijhawm Sijhawm: Nws yuav siv sijhawm 6-12 lub hlis rau patina kom ruaj khov rau sab nraum zoov-pib raws li lub teeb liab liab, tom qab ntawd hloov mus rau hauv cov xim tsaus grey / xim av txheej uas yuav tsis flake lossis tev.
Qhov Zoo Tshaj Plaws: Thaum tsim, patina nres ntxiv corrosion, tshem tawm qhov xav tau kev pleev xim, galvanizing, lossis kev saib xyuas tsis tu ncua -txuag sijhawm thiab nqi.
Q355GNH's Corrosion Performance nyob rau hauv txawv sab nraum ib puag ncig
Nws qhov kev tiv thaiv corrosion hloov mus rau ntau qhov chaw sab nraum zoov, nrog qhov sib txawv me ntsis raws li ib puag ncig yam xwm txheej - ntawm no yog qhov nws ua tau zoo li cas hauv cov xwm txheej:
1. Cov cheeb tsam me me hauv nroog / Suburban (Qhov Zoo Tshaj Plaws)
Kev ua tau zoo: Zoo heev -corrosion rate Tsawg dua lossis sib npaug li 0.025mm / xyoo, txhais tau tias nws tuaj yeem nyob tau 40+ xyoo sab nraum zoov yam tsis muaj kev puas tsuaj loj.
Piv txwv li: Cov chaw ua si hauv nroog, cov vaj tsev nyob, cov chaw tiv thaiv hauv nroog - tsis tshua muaj ntsev los yog cov pa phem hnyav.
2. Cov cheeb tsam huab cua txias sab nraum zoov
Kev ua tau zoo: zoo heev-nws txhim kho qis- qhov kub thiab txias ua haujlwm nrog patina los tiv thaiv corrosion txawm nyob rau hauv khov, ntub dej.
Lus Cim: Hauv cov cheeb tsam uas muaj daus hnyav, yaug qhov chaw qee zaus tom qab snowmelt kom tshem tawm cov tshuaj deicing, uas tuaj yeem ua kom nrawm me ntsis patina tsim tab sis tsis ua rau cov hlau puas.
3. Cov cheeb tsam me me ntug dej hiav txwv (tseem muaj ntsev tsawg)
Kev ua tau zoo: Zoo- tawm tsam ntsev tsuag yog muab tso rau 50+ meters ntawm ntug dej. Lub patina blocks ntsev hais kom ncav cuag cov hlau substrate.
Tswv yim tswv yim: Yaug nrog dej tshiab txhua hli kom tshem tawm cov ntsev ntxiv, kom ntseeg tau tias cov patina tseem nyob.
4. Hnyav Industrial/High-Cov pa phem
Kev ua tau zoo: Txaus siab- tiv thaiv corrosion zoo dua li cov hlau zoo tib yam, tab sis yuav tsum tau ntxuav qee zaus kom tshem tawm cov plua plav lossis pa taws.
Nco tseg: Tsis txhob raug cuam tshuam ncaj qha rau cov pa taws hnyav (piv txwv li, cov nroj tsuag tshuaj), vim tias kev sib cuag ntev tuaj yeem degrade lub patina dhau sijhawm.
Cov lus qhia yooj yim los txhawb Q355GNH sab nraum zoov Corrosion Resistance
Xyuas kom muaj qhov cua zoo: Mount Q355GNH cov khoom uas muaj qhov sib txawv kom tsis txhob muaj cov av noo, uas ua kom nrawm dua thaum ntxov - theem xeb ua ntej tsim patina.
Khaws qhov chaw huv si: So cov roj, roj, lossis cov plua plav hnyav sai sai -kev sib kis cuam tshuam kev loj hlob ntawm patina thiab ua rau tsis muaj zog corrosion.
Tsis txhob sib cuag nrog cov hlau zoo tib yam: stacking lossis mounting Q355GNH nrog uncoated carbon steel ua rau galvanic corrosion, accelerating rusting.
Hauv cov ntsiab lus, Q355GNH Corten Steel ua tau zoo tshaj plaws sab nraum zoov, nrog kev tiv thaiv corrosion uas tawm tsam cov hlau zoo tib yam thiab cov qauv huab cua feem ntau - cov hlau tsis muaj zog. Nws lub ntuj patina muab kev tiv thaiv ntev ntev, thiab nrog kev hloov pauv ib puag ncig yooj yim, nws tuaj yeem vam meej nyob rau hauv yuav luag txhua qhov xwm txheej sab nraum zoov- xa cov kav ntev thiab tsis tshua muaj txij nkawm rau ntau xyoo.
