Hard anodized aluminium profile, tseem hu ua hard coat aluminium, yog ib hom khoom siv txhuas uas tau dhau los ua cov txheej txheem electrochemical qhov chaw ntawm cov khoom tau hloov mus rau hauv ib qho nyuaj, corrosion-resistant txheej ntawm aluminium oxide. Cov txheej txheem no tseem hu ua nyuaj anodizing, thiab nws koom nrog rau immersing cov khoom txhuas nyob rau hauv ib tug electrolytic da dej, qhov twg nws yog sai oxidized. Qhov tshwm sim yog cov khoom siv ruaj khov, siv tau ntev, zoo tagnrho rau kev siv ntau yam kev lag luam.
Anodized aluminium yog hais txog cov txheej txheem ntawm kev tsim cov txheej txheem oxide rau saum npoo ntawm txhuas. Aluminium feem yog thawj zaug ntxuav thiab muab tso rau hauv ib qho kev daws teeb meem electrolyte, qhov twg ib qho ncaj qha tam sim no dhau los ntawm nws. Qhov no ua rau cov pa oxygen ions los ua ke nrog cov txhuas los ua ib txheej nyias, ntxeem tau oxide uas tiv thaiv qhov chaw los ntawm kev ntxiv oxidation thiab corrosion.
Lub thickness ntawm anodic oxide txheej tsim thaum lub sij hawm nyuaj anodizing muaj peev xwm nyob ntawm 25 mus rau 150 microns, piv rau 5 mus rau 25 microns rau niaj hnub anodizing.
Thaum ob qho tib si anodized aluminium thiab hard anodized aluminium muab cov txiaj ntsig ntawm kev tiv thaiv nto los ntawm corrosion, tawv anodized aluminium muab kev tiv thaiv ntau dua thiab kav ntev. Qhov no ua rau nws zoo tagnrho rau siv nyob rau hauv kev xav tau thiab hnyav ib puag ncig xws li aerospace, tub rog, thiab kev siv tsheb uas muaj zog thiab tiv thaiv kev puas tsuaj thiab hnav yog qhov tseem ceeb. Tsis tas li ntawd, nyuaj anodizing kuj tuaj yeem siv rau kev kho kom zoo nkauj, vim nws tuaj yeem tsim ntau yam xim thiab ua tiav nyob ntawm cov alloy thiab cov txheej txheem electrochemical siv.
Hauv kev xaus, anodized aluminium thiab hard anodized aluminium yog ob qho tib si kev kho kom zoo nkauj uas muaj kev tiv thaiv corrosion thiab hnav. Txawm li cas los xij, nyuaj anodizing muab ib txheej tuab dua thiab muaj zog dua oxide uas muab kev tiv thaiv ntau dua thiab ua haujlwm ntev. Thaum nws kim dua, nyuaj anodizing yog qhov tseem ceeb rau cov ntawv thov uas xav tau kev tiv thaiv rau cov xwm txheej hnyav, ua rau nws muaj kev xaiv nrov thoob plaws ntau yam kev lag luam.
