Muaj ntau yam kev kho mob saum npoo rau aluminium alloy plhaub, uas yog tsim los txhim kho corrosion kuj, hardness, zoo nkauj thiab lwm yam khoom ntawm aluminium alloy nto. Nov yog qee qhov kev kho saum npoo:
1. Anodizing:
Anodizing yog txheej txheem los ntawm cov txheej txheem oxide yog tsim rau saum npoo ntawm aluminium alloy los txhim kho nws cov hardness thiab corrosion kuj. Cov txheej ntawm oxide zaj duab xis no feem ntau kuj muab kev xaiv rau dyeing los hloov cov tsos ntawm aluminium alloy.
2. Electrophoretic Txheej:
Electrophoretic txheej yog ib txoj hauv kev los ua ib qho kev sib txuam thiab muaj zog adhesion txheej rau saum npoo ntawm aluminium alloy. Cov txheej no feem ntau muaj qhov zoo corrosion thiab abrasion tsis kam.
3. Hmoov Txheej:
Txau txheej yog ua tiav los ntawm kev txau cov hmoov zoo li txheej rau saum npoo ntawm aluminium alloy thiab tom qab ntawd ci rau qhov kub kub kom kho nws. Cov txheej no muab cov tsos zoo thiab corrosion kuj.
4. Tshuaj Chromating:
Tshuaj chromium plating yog ib txoj kev los txhim kho corrosion kuj ntawm aluminium alloy nto. Nws tuaj yeem hloov xim ntawm qhov chaw thiab muab cov txheej txheem tiv thaiv.
5. Sandblasting:
Sandblasting yog ib txoj kev ntawm kev txau cov xuab zeb lossis lwm yam khoom siv hauv kev kub ceev kom hloov qhov kev ntxhib los mos thiab zoo li ntawm aluminium alloy nto. Qhov no kuj pab tshem tawm cov av thiab oxides ntawm qhov chaw.
6. Mechanical Polishing:
Mechanical polishing yog los txhim kho qhov tiav thiab gloss ntawm aluminium alloy nto los ntawm kev siv tshuab, xws li kev sib tsoo lossis polishing.
