Feem ntau siv deg kho ntawm aluminium extrusion heatsink

Feem ntau, qhov kev tiv thaiv corrosion ntawm aluminium profile radiator tsis muaj zog heev, yog li nws yog ib qho tsim nyog los ua qhov kev kho deg los ntawm anodic oxidation kom muaj kev tiv thaiv corrosion, hnav tsis kam thiab zoo nkauj ntawm txhuas.

Cov txheej txheem tseem ceeb ntawm oxidation txheej txheem ntawm aluminium profile heatsink yog raws li nram no:

Nto pretreatment:

Ntxuav lub profile nto los ntawm cov tshuaj los yog lub cev txoj kev los nthuav tawm cov ntshiab matrix, thiaj li yuav tau txais ib tug tiav thiab ntom khoom oxide zaj duab xis. Daim iav los yog matte (Matt) qhov chaw kuj tuaj yeem tau los ntawm kev siv tshuab.

Anodizing:

Raws li cov txheej txheem txheej txheem, qhov saum npoo ntawm aluminium profile yuav raug anodized los ua ib qho tuab, ntxeem tau thiab muaj zog adsorption zaj duab xis.

Lub qhov sealing:

Cov pores ntawm cov ntxeem tau oxide zaj duab xis tsim tom qab anodizing raug kaw, kom tiv thaiv kev ua qias tuaj, tiv thaiv corrosion thiab hnav tsis kam ntawm oxide zaj duab xis yog txhim kho. oxide zaj duab xis yog xim tsis muaj xim thiab pob tshab. Los ntawm kev siv lub zog adsorption ntawm oxide zaj duab xis ua ntej kaw lub qhov, qee cov hlau ntsev yog adsorbed thiab tso rau hauv lub qhov zaj duab xis, uas tuaj yeem ua rau cov duab ntawm aluminium profile qhia ntau xim uas tsis yog xim ntuj (nyiaj dawb), xws li dub, bronze, golden daj thiab stainless hlau.
