Q500nh Wights hlau kev ua haujlwm hauvMuaj cov ib puag ncig ib puag ncig(xws li, cov chaw muaj kev lag luam, roj / roj av / roj av) yogNyuaj vim qhov nrawm corrosionCov. Ntawm no yog cov ncauj lus kom ntxaws:
1. Cov nyom sib tw hauv cov chaw ib puag ncig
Sulfide-induced corrosion:
H₂S (hydrogen sulfide) reacts nrog hlau tiv thaiv patina, sib sauHlau Sulfide(Fes), uas muaj ntxeem tau thiab tsis tiv thaiv.

10-20x sai dua corrosionvs. ib txwm atmospheric raug (kev tshawb fawb qhia ~ 0.1-0.5 mm / xyoo poob hauv cov aav-h₂s aav).
2. Kev Pab Tswv Yim
| Mus cuag | Hauj tes | Sau ntawv |
|---|---|---|
| Cov Khaub Ncaws Tiv Thaiv(Xws li, epoxy / polyurethane) | Siab | Thaiv ncaj qha sulfide hu; yuav tsum tau saib xyuas. |
| Cathodic Kev Tiv Thaiv | Tswj kav | Siv nrog txheej txheej hauv kev siv nyiaj / xa dej. |
| Alloy Hloov Kho(piv txwv li, siab dua cu / cr Crats) | Txwv | Tej zaum yuav qeeb me ntsis tab sis tsis tiv thaiv sulfide nres. |
3. Qhov twg kom tsis txhob Q500NH
Cov Khoom Siv Roj Roj, Wastewater kev kho cov nroj tsuag, lossis ib qho twgHigh-h₂s (>50 ppm) ib puag ncig.

4. Tshwj
HauvTsawg-sulfideNroog / Cua (so₂<100 µg/m³), Q500NH performs acceptably with minor patina adjustments.
