Q500NH Wights hlau nyob rau hauv nitrate (No₃⁻) ib puag ncig: kev ua tau zoo & txaus ntshai
Q500NH Weathering Hlau QhiaNruab Nrab Tab sis Kuj Tshaj Tawm KujTxhawm rau nitrate-muaj ib puag ncig, nyob ntawm kev xav, Ph, thiab cov dej noo. Thaum nws tiv thaiv Patina muaj qee qhov kev tiv thaiv, Nitrates tuaj yeem ua kom nrawm dua rau qee yam kev mob:
Cov teebmeem tseem ceeb ntawm Nitrates ntawm Q500NH
Ua kom nrawm corrosion hauv acidic / ntub dej:
Nitrates (piv txwv li, los ntawm cov chiv lossis kev ua dej ntws) ua li oxidizers, txhawb nqa pitting thiab corrosion thaum noo noo.
Kev pheej hmoo siab dua nyob rau hauvTsawg-p pals (pH < 5) or stagnant water with high nitrate concentrations (>100 ppm).
Txwv tsis pub cuam tshuam hauv nruab nrab / qhuav cov xwm txheej:
Nyob rau hauv zoo-txau, neutral-pali (pH 6-8), nitrates ua rau muaj kev hem thawj tsawg heev yog tias patina tseem ruaj khov.
Cov tswv yim Kev Pab Nkhaus
Txheej: Thov epoxy lossis polyurethane txheej los cais cov hlau.
Cathodic Kev Tiv Thaiv: Siv nyob rau hauv high-nitrate, waterlogged ib puag ncig.
Khoom Lwm Los: Rau qhov raug mob loj (piv txwv li, kev tso tsheb hlau luam cia khoom), xav txogStainless hlau (316L)los yog fiber ntau-txhawb polymers (frp).
Cov tswv yim pom zoo
Q500nh yuav zamTsawg-rau-mob nitrate kis(piv txwv li, kev ua liaj ua teb cua), tab sis rau lub sijhawm ntev detrability nyob rau hauv high-nitrate xau / dej, sib txuas tiv thaiv kev tiv thaiv nrog kev tshuaj xyuas.
