Spa -} h huab cua hlau ua qhov zoo tshaj plaws hauv cov chaw ib puag ncig hauv qab no, nyob ntawm ntug kev tiv thaiv corrosion:
1. Cov chaw ib puag ncig zoo tagnrho
TIVCTATE URBAN / CHAW NYOB(xws li, Northern Europe, Nyiv)
Vim li cas?Dej nag thiab huab cua huv kom khov kho patina tsim.
Corrosion tus nqi: 0.01-0.03 mm / xyoo tom qab stirilization.
Cov Huab Cua Qhuav(xws li, Arizona, Central Australia)
Vim li cas?Tsawg cov av noo qeeb qeeb surrows zuj zus; Patina stimilizes maj mam tab sis uniformly.
2. Zoo nrog kev txwv me me
Cov ntug dej hiav txwv (100+ m ntawm ntug dej)
Vim li cas?Ntsev tshuaj tsuag yog diluted; CR / NI cov ntsiab lus tiv taus pitting.
Tus ntsis: Yaug cov chaw ib ntus kom tshem tawm cov kua qab ntsev.
Cov Cheeb Tsam Muaj (Tsawg dua li)
Vim li cas? SPA-H's Cr/Cu oxides resist weak acid rain (pH >4.5).
3. Qhov nyuaj (xav tau kev tsim qauv)
Ntug dej hiav txwv slicash zones(piv txwv li, piers, seawalls)
Kev twv: Chlorides rau txim rau cov xeb tsis muaj xeb.
Lus teb: SivNi {{- Txhim Kho Spa - h(0.5-1.0% ni) lossis stadless cladding.
Hnyav Industrial
Kev twv: Acidic rust nce porosity.
Lus teb: Pre {- oxidize + thov cov khoom qab zib.
4. Tsis tsim nyog yam tsis muaj kev tiv thaiv
Brackish dej raus dej
Cov tshuaj acid tshuaj (ph<3)
