Kev saib xyuas yooj yim niaj hnub (txhua qhov chaw sab nraum zoov ib txwm muaj)
Tsuas yog yaug cov duab puab nrog dej huv 2-3 zaug hauv ib xyoos (lossis so nrog ib daim ntaub mos muag) kom tshem tawm cov plua plav, cov noog, thiab cov khib nyiab;zam cov kua qaub/alkaline ntxuav, cov ntaub plaub hlau, los yog cov cuab yeej abrasiveuas ua rau puas patina txheej. Xyuas kom cov duab puab muaj cov kua dej zoo / qhov cua kom tiv thaiv cov dej tsis sib xws thiab patina tsis sib xws.
Kev tiv thaiv phiaj xwm (tsuas yog ib puag ncig hnyav)
Rau sculptures nyob rau hauv siab - thaj chaw ntsev ntug dej hiav txwv (tsawg dua los yog sib npaug li 1km ntawm lub hiav txwv), hnyav industrial zones nrog acid pos huab / plua plav, los yog siab -humidity kaw qhov chaw: tshuaj tsuag anyias, UV-resistant pob tshab weathering steel sealerntawm patina paub tab ib zaug txhua 1-2 xyoos. Qhov no khaws cov patina qhov kev ntxhib los mos thiab xim thaum tiv thaiv pitting corrosion thiab patina tev.
Kev puas tsuaj tshwm sim (kev cuam tshuam tsawg kawg nkaus)
Rau kev khawb me me / hnav ntawm patina, tawm ntawm thaj chaw mus rau huab cua huab cua -ASTM A606's alloy cov ntsiab lus (Cu/Cr/Ni) yuav nws tus kheej- kho lub patina dhau sijhawm. Rau qhov kev puas tsuaj loj heev nthuav tawm cov hlau liab qab, ntxuav thaj chaw nrog daim ntaub qhuav thiab cia nws tsim patina tshiab; tsis muaj xeb tshwj xeeb tshem tawm lossis kho.
Qhov tseem ceeb tu taboos
Tsis txhob siv cov xim zoo tib yam, epoxy, lossis roj-raws li txheej (lawv npog lub patina thiab tev tawm raws li cov hlau xeb sab hauv); tsis txhob txav cov duab puab ntau zaus kom tsis txhob muaj kev sib txhuam kev puas tsuaj rau cov txheej txheem patina.
