Tswj Oxidation rau Uniform Patina
Ua ntej-patination siv cov txheej txheem xeb thiab tswj cov xwm txheej (60–70% av noo, 20–25 degree) txhawm rau ua rau cov tshuaj tiv thaiv ntawm cov hlau alloying ntsiab (Cu, Cr, Ni) nrog oxygen thiab noo noo. Tsis zoo li ntuj huab cua, uas yuav ua rau patchy, xoob xeb vim qhov tsis sib xws ntawm ib puag ncig (piv txwv li, ntxoov ntxoo, dej stagnant), cov txheej txheem no tsim ib qhonruam, nplua -grained patina txheej(10-20 μm tuab) thoob plaws tag nrho saum npoo, suav nrog cov npoo thiab welds. Cov txheej txheej no thaiv cov xov xwm corrosive los ntawm kev nkag mus rau cov hlau substrate zoo dua.
Strengthened Patina ntom
Kev tswj hwm ua ntej -patination ib puag ncig inhibits kev loj hlob ntawm ntxhib, nkig xeb crystals thiab txhawb kev tsim ntawmtooj liab- nplua nuj, chromium- ntxiv dag zog rau hlau oxides-cov tseem ceeb tiv thaiv ntawm huab cua steel patina. This dense structure has lower porosity than naturally formed patina, making it more resistant to chloride ion infiltration (a key threat in coastal areas) and preventing pitting corrosion.
Eliminates Initial Corrosion Vulnerability
Yog tsis muaj ua ntej-patination, S355J2W steel ntsej muag a6-12 lub hlis tsis muaj zogThaum lub sij hawm ntuj tsim patina, qhov twg cov hlau tshiab raug rau cov ntsiab lus corrosive thiab nquag mus rau hauv zos rusting. Ua ntej-patination hla mus rau theem no los ntawm kev xa cov txheej txheem tiv thaiv tag nrho ua ntej ntawm - qhov chaw teeb tsa, ncaj qha txhim kho cov hlau tsis zoo los ntawm kev pib ua haujlwm.
Txo Patina Runoff Staining
Ntuj huab cua feem ntau ua rau "xeb dej ntws" (soluble hlau ntsev) uas stains cov ntaub ntawv uas nyob ib sab. Ua ntej-patination stabilizes oxide txheej nyob rau hauv lub Hoobkas, txo cov soluble xeb tivthaiv thiab txo staining txaus ntshai thaum lub sij hawm ntawm - siv site-thaum tuav lub patina txoj kev tiv thaiv muaj nuj nqi thiab aesthetic cim.
