Dab tsi yog Corrosion Resistance Ntawm Aluminium Tom Qab Anodizing
Nov 25, 2022
Tom qab anodic oxidation txheej txheem, corrosion kuj ntawm txhuas yuav zoo heev.
Lub thiaj li hu ua anodic oxidation yog hais txog cov txhuas phaj tso rau hauv cov khoom siv electrolyte (xws li sulfuric acid, chromic acid, oxalic acid, thiab lwm yam) raws li cov anode, nyob rau hauv tej yam kev mob thiab lwm yam tam sim no, electrolysis. Los ntawm cov txheej txheem anodic oxidation, cov alumina ntom ntom yog tsim rau saum npoo ntawm cov phaj txhuas, uas ua lub luag haujlwm ntawm kev sib cais huab cua. Hlau corrosion yog qhov ua tau zoo ntawm cov hlau oxidation los ntawm cov tuam txhab hauv nruab nrab hauv huab cua. Tam sim no lub hav zoov ntawm no txheej ntawm ntom alumina zaj duab xis plays lub luag hauj lwm ntawm cais oxygen, uas kuj pab txhim kho corrosion kuj ntawm cov hlau. Tsis tas li ntawd, cov txheej txheem anodic oxidation tuaj yeem txhim kho qhov tawv thiab hnav tsis kam. Anodizing txheej txheem ntawm txhuas yog dav siv nyob rau hauv mechanical qhov chaw, aircraft thiab tsheb qhov chaw, precision instruments thiab lwm yam teb.
Tsis tas li ntawd, cov txheej nyias nyias ntawm oxide zaj duab xis muaj ntau qhov micro qhov, tuaj yeem nqus tau ntau yam lubricants, tsim nyog rau kev tsim lub tog raj kheej lossis lwm yam hnav-tiv taus; Membrane microporous adsorption muaj peev xwm muaj zog, tuaj yeem nqus cov xim, xim rau ntau yam xim zoo nkauj. Ntau cov xov tooj muaj yeeb yuj, xws li champagne kub, siv cov txheej txheem anodic oxidation los kho cov hlau thiab ces adsorb cov xim sib xws.
