Desiccants yog cov khoom uas nqus dej noo los ntawm ib puag ncig, ua rau lawv qhov tseem ceeb hauv ntau qhov kev lag luam rau kev khaws cov khoom thiab cov khoom siv. Ntawm ntau cov desiccants muaj, activated alumina stands vim nws cov yam ntxwv tshwj xeeb thiab versatility.
Activated alumina yog ib daim ntawv zoo heev ntawm txhuas oxide, tsim los ntawm kev kho aluminium hydroxide nrog cua sov. Cov txheej txheem no txhim kho nws qhov chaw saum npoo av thiab muaj peev xwm adsorption, ua rau nws ua tau zoo desiccant. Nrog rau thaj tsam ntawm thaj tsam txog li 300 m² / g, activated alumina tuaj yeem nqus dej vapor ntau, ua rau nws zoo tagnrho rau cov ntawv thov uas tswj cov dej noo tseem ceeb.
Ib qho tseem ceeb ntawm kev siv alumina activated yog nyob rau hauv qhuav ntawm gases thiab kua. Hauv kev lag luam chaw, nws yog feem ntau ua haujlwm kom tshem tawm cov dej noo los ntawm cov cua compressed thiab cov pa roj carbon monoxide, tiv thaiv corrosion thiab ua kom cov khoom siv tau zoo. Tsis tas li ntawd, activated alumina yog siv nyob rau hauv kev tsim cov tshuaj purity siab thiab kws tshuaj, qhov twg txawm tias cov dej noo noo tuaj yeem cuam tshuam cov khoom zoo.
Activated alumina kuj tseem ua lub luag haujlwm tseem ceeb hauv kev lag luam kho dej. Nws muaj txiaj ntsig zoo hauv kev tshem tawm cov tshuaj fluoride thiab arsenic los ntawm cov dej haus, ua rau nws muaj txiaj ntsig zoo hauv cov dej huv huv. Nws lub peev xwm los adsorb cov kab mob thaum tswj hwm tus nqi qis qis kom ntseeg tau tias cov dej kho tau zoo rau kev noj.
Ntxiv mus, activated alumina yog reusable. Nws tuaj yeem rov tsim dua los ntawm cua sov, tso cai rau nws tso tawm cov dej noo noo thiab rov siv dua. Cov yam ntxwv no tsis yog tsuas yog ua rau nws raug nqi xwb tab sis kuj yog ib puag ncig tus phooj ywg, vim nws txo cov khib nyiab cuam tshuam nrog kev siv ib zaug desiccants.
Nyob rau hauv xaus, activated alumina yog ib tug haib desiccant nrog ntau yam kev siv nyob rau hauv ntau yam industries. Nws muaj peev xwm nqus dej noo, ua ke nrog nws cov khoom siv rov ua dua tshiab, ua rau nws yog ib qho khoom siv tseem ceeb rau kev tswj xyuas cov khoom zoo thiab kev nyab xeeb hauv qhov chaw noo noo-rhiab heev.
