Yuav ua li cas yog aluminium profile pleev xim?
Kev siv cov aluminium profiles tau dhau los ua ntau thiab ntau dua. Hauv kev siv, peb yuav muaj ntau txoj hauv kev rau kev kho deg ntawm aluminium profiles, thiab xim yog ib qho ntawm lawv. Yog li yuav ua li cas xim lub txhuas profile?
Ua ntej tshaj plaws, aluminium profile yuav tsum tau oxidized. Lub extruded aluminium alloy profile muaj qhov tsis zoo ntawm corrosion tsis kam, yog li nws yuav tsum tau kho los ntawm anodizing kom muaj kev tiv thaiv corrosion, hnav tsis kam thiab zoo li aluminium profile.
Tom qab ntawd cov kauj ruam tshwj xeeb yog raws li hauv qab no:
1. Nto pretreatment: Siv tshuaj los yog lub cev txoj kev los ntxuav qhov chaw ntawm qhov profile kom nthuav tawm cov ntshiab substrate, thiaj li yuav tau ib tug tiav thiab ntom khoom oxide zaj duab xis. Daim iav los yog matt (matt) nto kuj tuaj yeem tau los ntawm kev siv tshuab.
2. Anodic oxidation: Tom qab deg pretreatment, nyob rau hauv tej yam txheej txheem tej yam kev mob, anodic oxidation tshwm sim nyob rau saum npoo ntawm substrate los ua ib txheej ntawm ntom, ntxeem tau, thiab muaj zog adsorption AL203 zaj duab xis.
3. Pore sealing: zaj duab xis pores ntawm cov ntxeem tau oxide zaj duab xis tsim tom qab anodic oxidation raug kaw, kom tiv thaiv kev ua qias tuaj, corrosion tsis kam thiab hnav tsis kam ntawm oxide zaj duab xis yog txhim kho. oxide zaj duab xis yog xim tsis muaj xim thiab pob tshab. Siv lub zog adsorption ntawm oxide zaj duab xis ua ntej sealing, qee cov hlau ntsev yog adsorbed thiab tso rau hauv cov yeeb yaj kiab qhov pores, uas tuaj yeem ua rau lub ntsej muag ntawm qhov profile tshwm ntau xim uas tsis yog cov xim qub (nyiaj dawb), xws li: dub, bronze. , Golden daj thiab stainless hlau xim, thiab lwm yam.
