Kev siv
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm peb lub tshuab txais alumina yog nws cov duab kheej kheej, uas txhim kho nws cov txiaj ntsig zoo li lub siab viav vias roj adsorbent. Cov khoom ntxeem tau dawb no muaj qhov loj me thiab qhov chaw du rau kev pom zoo adsorption thiab pom. Lub zog txhua yam ntawm activated alumina kom ntseeg tau tias nws khaws nws cov duab qub txawm tias tom qab nqus dej, tsis muaj qhov o lossis tawg. Qhov no guarantees nws lub neej ntev thiab durability nyob rau hauv ntau yam kev siv.
Lwm qhov tseem ceeb ntawm activated alumina yog nws lub zog hygroscopicity, uas ua rau nws tshem tawm cov kab dej molecules zoo. Qhov no ua rau nws muaj txiaj ntsig zoo desiccant, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas yuav tsum tau ziab kom tob. Activated alumina kuj tsis yog-tshuaj lom, tasteless, insoluble nyob rau hauv dej thiab ethanol, uas ua kom nws muaj kev ruaj ntseg nyob rau hauv txawv ib puag ncig. Nws zoo heev thermal stability tswj kev ua tau zoo ib yam txawm tias kub siab.
Tsis tas li ntawd, peb cov activated alumina yog tsim los ua kom sib haum nrog cov khoom siv hluav taws xob uas tsis muaj cua sov, muab cov kev daws teeb meem zoo rau kev siv tas mus li. Cov yam ntxwv no ua rau nws xaiv ntau yam thiab txhim khu kev qha rau kev lag luam xws li roj thiab roj, petrochemical, tshuaj, thiab lwm yam. Txawm tias tom qab siv dua, nws khaws nws cov qauv qub thiab kev ua tau zoo, ua kom muaj kev sib luag thiab kev ntseeg siab hauv cov txheej txheem pom.
Nyob rau hauv xaus, activated alumina yog ib tug npaum thiab ntau yam tshuaj rau catalysts thiab catalyst txhawb nyob rau hauv cov tshuaj tiv thaiv. Nrog nws cov cheeb tsam loj tshwj xeeb, zoo thermal stability thiab muaj zog adsorption kev ua tau zoo, nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv. Nws cov duab kheej kheej, lub zog siab txhua yam thiab hygroscopicity ua rau nws muaj zog viav vias roj adsorbent, zoo tagnrho rau ziab kom qhuav thiab pom. Cia siab rau peb cov activated alumina kom ua tau raws li koj qhov kev xav tau ntawm kev lag luam thiab paub txog lub zog ntawm cov khoom siv catalytic siab heev.
