09cupcrni - ayog kev tshaj lijWeathering & Acid - tsis kam hlauTsim rau qhov kev lag luam corrosion heev hauv kev lag luam hnyav thiab chaw ua haujlwm marine. Nws ua ketooj liab (cu), phosphorus (p), chromium (CR), thiab npib tsib)Txhawm rau ua qhov ntom ntom, tus kheej {- tiv thaiv oxide txheej uas txwv tsis pub muaj xeb ntxiv thiab tiv taus acidic kuab paug.
Cov Ntsiab Lus Tseem Ceeb:
Tshwj kev txiav txim siab corrosion tsis kam(3-8 × zoo dua li cov roj carbon)
Acid & Tshuaj Tshuaj(zoo tagnrho rau cov kuab paug / muaj kev muaj zog)
Siab Zog & Veldability(Haum rau cov txheej txheem kev thov)
Tsawg txij nkawm(xeb txheej ua ib lub ntuj thaiv)
Aesthetic xeb patina(Siv hauv kev ua lag luam niaj hnub)

Corrosion & Acid Resistance Kev Ua Haujlwm
Atmospherric corrosion:
Ua yeeb yam tshwj xeeb hauvMuaj, ntug dej hiav txwv, thiab hauv nroogatmospheres.
Rust txheej ruaj khov nyob hauv6-18 lub hlis, txo qis ntxiv degradation ntxiv.
Acid & Tshuaj Kuj:
Tsis kamSulphur dioxide (so₂), chlorides, thiab cov acids tsis muaj zogZoo dua li cov qauv huab cua.
Zoo tagnrho rauTshuaj lom neeg tshuaj, kev ua qias tuaj - cov cheeb tsam hnyav, thiab marine qauv.
