Lub corrosion tiv taus ntawm cov huab cua tshiabdoes face challenges in high-temperature, high-humidity environments, tab sis nws ua tau zoo nyob ntawmAlloy Muaj pes tsawg, Kabmob xwm txheej, thiabTsim Cov Qauv TsimCov. Ntawm no yog cov ncauj lus kom ntxaws:
1. Kev cuam tshuam ntawm cov av noo & Kub
Ua kom nrawm thaum lub corrosion:
In tropical/marine climates (e.g., >80% RH, >30 degree), cov txheej txheej xeb txheej nrawm dua tab sis yuav pib muaj ntau dua, ua rau:
Siab dua luv - lub sij hawm corrosion (txog2 × sai duadua li huab cua huab cua huab cua).
Muaj peev xwm "Khiav - tawm" xeb stain yog tias tso kua mis yog neeg pluag.
Ntev -} lub sij hawm ruaj khov:
Nrog kev ua kom raug zoo (piv txwv li,CU + CR + NI), lub pov thawj thaum kawg pab pawg rau kev tiv thaiv txheej txheem ({{1}} feooh), txawm hais tias qhov no yuav sivntev dua (2-5 xyoos)thiab cov huab cua sov drier.
2. Qhov tseem ceeb muaj feem cuam tshuam
| Yam tseem ceeb | Ua rau | Lus teb |
|---|---|---|
| Kev xa tshuaj dawb(Nqaum) | Chlorides rau txim loj tsis taus, ua rau pitting. | Kev sivhigh - cr / ni cov qib(piv txwv li, Astm A588 qib K). |
| Cyclic ntub -} qhuav | Cov dej nag ntau heev + cua sov cuam tshuam kev tsim Patina. | Kev tsim uaSloped nthwv dej (>3 Qib) rau kev tso kua mis. |
| Sulphur muaj kuab paug(Muaj) | So₂ ua Acidic xeb (Feso₄), ua kom dawb huv. | Qhia meejNtau dua P Ntsiab Lus (0.1–0.15%). |
3. Khoom siv & Tsim kev txiav nyiaj
Kev kho kom zoo tshaj plaws alloy:
Tooj Liab (0.3-0.5%): Steeilizes ruaj khov nyob rau hauv cov av noo.
Nickel (0.3-1.0%): Txo cov tshuaj chloride rhiab.
Chromium (1.0-2.5%): Txhim kho cua sov / av noo tsis kam.
Kev tiv thaiv kev tiv thaiv:
Ua ntej - oxidation kev kho mobrau dhia pathtart patina tsim.
Silane FealanRau cov tub rog huab / muaj huab cua.
4. Tiag -} Cov ntaub ntawv ntiaj teb
Singapore(Tropical cov tubrog):
Corrosion tus nqi:0.05-0.1 mm / xyoo(vs . 0.02 hli / xyoo nyob rau hauv temperate ib thaj).
Cov ntaub ntawv muaj kev vam meej:Marina Bay Hlau Sculptures({10+ xyoo, kev txij nkawm tsawg).
Florida Nqaum Txuas hniav:
3 × siab duaThawj zaug corrosion vs. Island, tab sis kev ruaj khov tom qab 7 xyoo.
