Cov kev coj ua txuj ci ntawm daim ntawv thov sab nraum qab Q460NHNHERING STEEL
1. Cov khoom siv ntawm Q460NH
Qib Q460N yog ib lub zog loj ntawm cov txheej txheem sib txawv ntawm cov txheej txheem ntawm Suav teb Cov yam ntxwv tseem ceeb suav nrog:
Tshuaj Muaj Tshuaj: Alloy ntsiab (Cu, CR, NI, P) Txhawb txoj kev tsim ntawm cov txheej dense, cov khoom tsis zoo uas txwv tsis pub corrosion.
Cov Khoom Siv Neeg Kho Tshuab: Yam tsawg kawg tau lees lub zog ntawm 460 MPa, ua rau nws haum rau cov khoom ris-cov kabmob qauv.
Corrosion Kuj: Raws li cov xwm txheej tsim nyog, cov mob corrosion ruaj khov ntawm 20-30% uas ntawm cov roj carbon hlau tom qab patina tsim.
2. Ncaj Qog Ncaj Ncees
Q460nd yogTsim los rau kev siv tau sab nraum zoov sab nraum zoov sab nraum zoov sab nraum zoov sab nraum zoov sab nraum zoov sab nraum zoov sab nraum zoov, tab sis kev thov kev vam meej yuav tsum muaj:
A. Environenional
Qhov zoo tshaj plaws: Nyob deb nroog / Nroog Umospheres nrog cov pa phem nruab nrab (so₂ <100 mg / m²²²).
Cov chaw sib tw:
Cov ntug hiav txwv Raj (CHLORIDE
Cov Cheeb Tsam muaj nrog cov acid oformition (ph <4.5) yuav cuam tshuam patina tsim.
B. Kev Txiav Txim Siab Loj
Tsis txhob noo / av ntxiab: Xyuas kom ntseeg tus kheej cov dej ntws (piv txwv li, sloped nthwv dej, tsis muaj cremices).
Galvanic kev rho tawm: Tiv thaiv kev sib cuag ncaj qha nrog ntau cov hlau nplaum (piv txwv li, tooj liab, tooj liab) kom tsis txhob kho corrosion.
3. Thaum pib txij nkawm raws tu
Txhawm rau kom ntseeg tau tias kev ua tau zoo tshaj plaws:
A. Deg Npaj (Pre-raug)
Abrasive ntxuav: SA 2½ cour blast tu (ISO 8501-1) kom tshem tawm zeb nplai thiab txhim kho Patina kev sib dhos.
Kev Siv Tshuaj Lom Zem: Daim ntawv thov ntawm xeb-stablizing daws (piv txwv li, tannic acid-bats kho kev txhim kho patina.
B. Kev tswj hwm B.
Siv theem siv: Cov txheej txheem kev ua haujlwm sau ua rogoff nyob ib ntus
Lub Sij Hawm Ntev: Teeb tsa cov kws ua vajtsev (overhangs, plab hlaub) los ncaj qha xeb dej kom deb ntawm cov chaw rhiab.
C. Kev Tshuaj Xyuas & Hloov Kho
Kev tshawb xyuas peb lub hlis kuaj mob thaum thawj 2 xyoos los ntsuas cov kev txhim kho patina.
Cov teeb meem hauv zos (piv txwv li, streaking) yuav xav kom muaj qhov chaw kev kho nrog cov neeg sawv cev Patinh.
4. Cov ntaub ntawv sib piv
| Yam tseem ceeb | Corrosion tus nqi (μm / xyoo) |
|---|---|
| Q460nd (Stridilized PATINA) | 5–10 |
| Q460nd (Thawj) | 15–25 |
| Carbon Steel (Unpainted) | 50–100 |
5. Cov lus pom zoo rau cov ntawv thov tseem ceeb
Txuas hniav / infrastructure: Ua raws GB / T 19292.2 rau kev ntsuas cov huab cua kev sib xyaw.
Cov Khoom Taw Qhia: Qhia kom paub qhov kev sim tshuaj xyuas kom paub tseeb kev ua haujlwm zoo nkauj.
High-humity microclimates: Xav txog kev kho mob hydrophibic.
