Txoj kev ntawm oxidation rau saum npoo ntawm aluminium profiles
1. Ntuj oxidation.
Aluminium alloy profiles nyob rau hauv tej yam ntuj tso ib puag ncig thiab oxygen nyob rau hauv cov huab cua yuav hnov mob, lub nto tsim ib txheej ntawm alumina tiv thaiv txheej, teem lub sab hauv substrate thiab oxygen mus rau react. Thiab cov txheej txheem tiv thaiv no yog pob tshab, peb hu nws cov oxide zaj duab xis. Ntuj oxidation ntawm zaj duab xis yog tsis sib xws, xim tsis zoo, corrosion kuj tsis muaj zog.
2. Tshuaj oxidation.
Qhov saum npoo degreasing aluminium alloy profile rau hauv cov oxidant thiab tus neeg sawv cev oxidation kev daws teeb meem, lub luag hauj lwm ntawm tus neeg sawv cev yog ua kom cov oxidation zaj duab xis nyob rau hauv cov txheej txheem ntau lawm ib nrab yaj, tsim pores, kom oxidation txuas ntxiv, oxidation zaj duab xis yuav thickened. Muaj ntau ntau hom kev daws teeb meem oxidation, feem ntau nrog chromate li oxidant thiab carbonate ua tus neeg sawv cev. Qhov zoo ntawm cov tshuaj oxidation yog yooj yim los tswj thiab yooj yim rau kev khiav lag luam. Qhov tsis zoo yog tias tus nqi siab dua, yuav ua rau muaj kev ua qias tuaj ib puag ncig, thiab los ntawm cov tshuaj oxidation ntawm oxide zaj duab xis yog thinner, muaj peev xwm tsim tau tsawg.
3. Anodized oxidation.
Muab cov txhuas profile rau hauv cov kua qaub electrolyte, ua ib qho anode, los ntawm high-voltage direct tam sim no, kom cov anions txav mus rau lub anode, thiab nyob rau hauv lub anode los tsim cov pa tshiab thiab anode aluminium alloy los tsim cov oxidation zaj duab xis. Cov kua qaub hauv electrolytes tuaj yeem ua rau ib nrab ntawm cov yeeb yaj kiab oxidation, tsim cov pores, kom cov tshuaj tiv thaiv oxidation tuaj yeem tsim qhov tob. Cov txheej txheem no ua rau saum npoo ntawm txhuas cov qauv ntxeem tau, tuaj yeem ua ntau yam kev kho xim, thiab tuaj yeem siv los ua cov tshuaj pleev xim hauv qab. Qhov zoo ntawm anode oxidation yog lub thickness ntawm oxidation zaj duab xis, ntau resistant rau corrosion, thiab tuaj yeem ua tiav hauv ntau. Qhov tsis zoo yog tseem ua paug rau ib puag ncig. Yog li ntawd, cov tuam txhab oxidation yuav tsum teeb tsa cov kav dej phwj tuaj, kom ua tau raws li cov qauv ntawm emissions.
