Aluminium lub Oxide txheej muab xam cov pa corrosion, tab sis ib puag ncig hnyav (piv txwv li, marine, kev tiv thaiv) xav tau kev tiv thaiv ntxiv. Hauv qab no yog cov tswv yim pov thawj los txhim kho lub sijhawm ntev thaum ua kev tswj hwm txhuas lub teeb ci ntsa iab:
1. alloy xaiv teeb meem
Xaiv cov qib corrosion-resistant qib nyiam li 5052- h32 (marine} t6 (cov qauv txheej txheem). Cov alloys muaj magnesium (mg) thiab manganese (mn), uas ntxiv dag zog rau Oxide txheej. Zam txhob siv 2000- series} series alloys hauv cov chaw puag ncig loj vim tooj liab uas yog corrosion.
2. Cov kev kho saum npoo rau kev tiv thaiv
Anodizing: Tsim cov yeeb yaj kiab dense oxide (txog li 25μm tuab) zoo tshaj plaws rau cov kws kos duab kos duab thiab cov neeg siv khoom siv hluav taws xob.
Hmoov txheej: muaj UV tsis kam thiab xim kev kho rau cov khoom siv sab nraum zoov (piv txwv li cov vaj huam sib luag rau hnub ci).
Cov txheej txheem hloov hloov dua tshiab: txhim kho cov xim pleev xim ntawm qhov chaw tsheb zoo li txhuas cov log.
Cov kev kho no muab cov txheej txheem ntxiv ntawm kev tiv thaiv ib puag ncig ib puag ncig.
3. Tsim Qauv & Ib puag ncig tswj
Zam kev ua txhaum uas noo noo tuaj yeem tsim tau hauv extruded aluminium profiles.
Siv cov roj hmab rwb thaiv tsev (piv txwv li, cov roj hmab roj hmab) los tiv thaiv cov galvanic corrosion ntawm txhuas thiab cov sib cais.
Thov Txhuas Cladding (piv txwv li, 3003 alloy) ntawm cov cores siab rau cov ntawv thov aerospace.
4. Txij Nkawm Kev Ua Haujlwm Zoo
Nquag huv si nrog ph-mis neutral daws kom tshem tawm cov ntsev tso nyiaj lossis cov kuab paug.
Rau welded sib koom ua ke, siv 5356 co tubkawm lim hlau kom txo qis intergranular corrosion.
Gnee pawg lus pom zoo
Rau cov phiaj xwm tseem ceeb, GNEE cov pab pawg muab cov kev sim ua kom zoo nkauj ntawm alloys zoo li 5083 (5754 (paired nrog txiav txhuas ua cov kev daws teeb meem.
