1. Qhov laj thawj tseem ceeb rau Brightness Fading
Inherent Weathering Property: S355J0WP yog tsim los ua huab cua hlau. Its core corrosion resistance relies on forming a dense, stable reddish-brown oxide film (patina) when exposed to air, moisture, or outdoor environments. Cov txheej txheem patination ntuj no yuav inevitably npog lub ci xim hlau nto, hloov nws nrog cov yam ntxwv weathered tsos.
Environmental Factors:
Sab nraum zoov raug (los nag, av noo, fumes, industrial fumes, ntug dej hiav txwv ntsev tsuag) accelerates nto oxidation thiab paug, ua brightness yuav txo tau nyob rau hauv lub lis piam mus rau lub hlis.
Cov chaw nyob sab hauv tsev uas muaj cov av noo siab lossis cov tshuaj vapors (piv txwv li, cov chaw tsim khoom, chaw kuaj mob) tuaj yeem ua rau muaj qhov tsis zoo los yog xeb xeb ntau tshaj 6-12 lub hlis.
Cov txheej txheem txwv: Kev ci ntsa iab los ntawm cov tshuaj lom neeg / kev kho cua sov (xws li electrolytic polishing, ci annealing) yog "kev hloov kho saum npoo" es tsis yog txheej txheej tas mus li. Lub hauv paus steel lub alloy muaj pes tsawg leeg (Cr, Cu, P) tseem tsav lub ntuj huab cua teb.
2. Durability ntawm Brightness nyob rau hauv ntau yam kev mob
3. Kev ceev faj kom txuas ntxiv Brightness Durability
Siv lub tsho tiv thaiv Clear: Qhov no yog txoj kev ua tau zoo tshaj plaws. Tom qab ua tiav qhov ci tiav, siv cov huab cua- tiv thaiv cov txheej txheem ntshiab (xws li, fluorocarbon clear coat, polyurethane clear coat) uas yog sib xws nrog weathering steel. Nws tsim ib qho kev thaiv kev tiv thaiv ya raws thiab oxygen, ncua kev tsim patina thiab tswj kev ci ntsa iab rau 3-8 xyoo (nyob ntawm txheej txheej zoo thiab tuab).
Xaiv Txoj Kev Brightening Txoj Cai: Mechanical polishing (xws li, daim iav polishing) tsim ib txheej txheej denser tshaj li tshuaj polishing, ua rau nws me ntsis resistant rau tarnishing. Muab nws nrog kev kho mob passivation (piv txwv li, chromate-dawb passivation) txhawm rau txhim kho qhov corrosion kuj ua ntej txheej.
Tswj Kev Siv Ib puag ncig: Tsis txhob siv S355J0WP nyob rau hauv kev sib cuag ncaj qha nrog dej ntsev, acidic/alkaline tshuaj, los yog siab -sulfur industrial emissions. Rau kev siv sab nraum zoov, xyuas kom cov kua dej kom zoo los tiv thaiv cov dej sib txuam ntawm qhov chaw.
Tsis tu ncua: Ntxuav lub ntsej muag ib ntus nrog cov ntaub mos muag thiab cov tshuaj ntxuav tes kom tshem tawm cov plua plav, cov pa phem, lossis cov dej lwg. Tsis txhob siv cov tshuaj ntxuav abrasive uas khawb qhov ci ntsa iab lossis txheej tiv thaiv.
Zam kev tshaj tawm -Kev kho mob tsis sib haum xeeb: Tsis txhob siv roj -raws li preservatives rau ntev - tiv thaiv lub sij hawm- tej zaum lawv yuav ua rau saum npoo daj. Xaiv rau dej-raws li, huab cua- tiv thaiv cov khoom tiv thaiv uas khaws cia qhov ci ci.
