Blocks txuas ntxiv corrosionlos ntawm kev ua yeeb yam raws li kev tiv thaiv kev tiv thaiv.
Tshem tawm qhov xav tau kev pleev ximNyob rau hauv feem ntau ib puag ncig (tsis zoo li cov hlau).
Ua 2-8x zoo dua li cov pa roj carbon(piv txwv li, Q355B) nyob rau hauv kev ntsuam xyuas ntev ntev.
2. Tsim nyog ib puag ncig
| Huab cua | Rau haum | Sau ntawv |
|---|---|---|
| Nroog / Nyob deb nroog | Zoo tshaj | Ruaj ruaj Patina cov ntawv hauv cyclic ntub / tej yam kev mob qhuav. |
| Muaj (so₂) | Tswj kav | Acid los nag yuav qeeb patina tsim; saib xyuas rau xeb ntawm kev xeb. |
| Nqaum (ntsev) | Pluag | Chlorides ua rau pitting; yuav tsum muaj kev tiv thaiv tiv thaiv. |
| Submerged / Av | Tsis phim | Tsis muaj patina cov ntawv; Siv alloys alloys hloov. |
3. Cov kev txwv tseem ceeb
Thawj zaug xeb dejTej zaum cov chaw uas nyob ib sab ib txwm muaj (ib ntus kev tswj hwm pom zoo).
Tsis yog rau chloride-nplua nuj thaj chawTshwj tsis yog coated (piv txwv li, txuas hniav nyob ze hiav txwv).
Zoo tshaj plaws rau: Txuas hniav, kis cov yees, kws kos duab façades, thiab sab nraum zoov sculptures nyob rau hauvuralland lossis cov chaw muaj kuab paug.
