Nrog rau acceleration ntawm industrialization, qhov kev thov rau cov ntaub ntawv refractory kuj qhia ib tug zuj zus. Raws li tus neeg sawv cev ntawm cov ntaub ntawv refractory, activated alumina tau txais kev saib xyuas ntau dua thiab tau dhau los ua cov khoom lag luam siab ntawm lub khw. Activated alumina yog cov khoom siv refractory uas muaj zog heev, tiv taus corrosion, hnav tsis kam thiab lwm yam khoom. Nws tuaj yeem siv dav hauv metallurgy, tshuaj lom neeg kev lag luam, kev tiv thaiv ib puag ncig, hluav taws xob hluav taws xob thiab lwm yam lag luam.
Hais txog activated alumina, ntau tus neeg yuav nug: Dab tsi yog qhov txawv ntawm nws thiab alumina? Qhov tseeb, activated alumina yog cov khoom siv alumina heev. Piv nrog dog dig alumina, nws muaj qhov siab dua ntom ntom ntom ntom ntom ntom ntom, ntau cov ion tsis xws luag thiab muaj zog acidity thiab alkalinity. Cov yam ntxwv zoo li no ua rau qhib alumina dav siv hauv ntau qhov chaw.
Nyob rau hauv kev lag luam metallurgical, activated alumina yog dav siv nyob rau hauv lub cub tawg linings, sintered ore npas, thiab lwm yam. Vim hais tias ntawm nws tsis tshua muaj zog tshav kub tsis kam thiab muaj peev xwm tiv taus yaig ntawm molten hlau nyob rau hauv high kub, nws yog siv los ntawm ntau lub tuam txhab steel loj. Tsis tas li ntawd, activated alumina kuj tseem tuaj yeem hloov graphite raws li cov khoom siv anode ntawm cov hluav taws xob hluav taws xob, muab cov hluav taws xob hluav taws xob rau lub neej ntev dua thiab zoo dua corrosion kuj.
Hauv kev lag luam tshuaj, activated alumina kuj ua lub luag haujlwm tseem ceeb. Nws yog dav siv hauv tshuaj catalysts, adsorbents, cais cov neeg ua haujlwm thiab lwm yam. Tshwj xeeb tshaj yog nyob rau hauv petrochemical ntau lawm, activated alumina tuaj yeem txhim kho cov kev xaiv ntawm kev tawg cov tshuaj tiv thaiv thiab cov khoom zoo, thaum tseem txo qis kev poob qis thiab txuag cov nqi ntawm cov diesel thiab catalyst.
Hauv kev tiv thaiv ib puag ncig, activated alumina kuj plays lub luag haujlwm tseem ceeb heev. Nws tuaj yeem siv los ua ib qho catalyst rau cov pa purification, hloov cov pa phem rau hauv cov khoom tsis zoo ntawm qhov kub thiab txias kom ua tiav cov txiaj ntsig ntawm purifying huab cua. Nyob rau tib lub sijhawm, activated alumina kuj tseem siv tau los ua ib qho adsorbent rau kev kho dej khib nyiab, adsorbing pollutants ntawm cov ntaub ntawv, yog li ua tiav cov txiaj ntsig zoo, kev lag luam, thiab kev kho ib puag ncig.
