Aluminium activated ndi porous kwambiri komanso zosunthika zinthu zotengedwa aluminium okusayidi (Al2O3). Amapangidwa chifukwa cha kuchepa kwa madzi m'thupi la aluminiyamu hydroxide, zomwe zimapangitsa kuti pakhale chinthu chaching'ono chokhala ndi malo okwera kwambiri komanso zinthu zabwino kwambiri za adsorption. Kuphatikizika kwapadera kumeneku kumapangitsa aluminiyamu yoyendetsedwa kukhala gawo lofunikira pamagwiritsidwe osiyanasiyana am'mafakitale, kuphatikiza kuyeretsa madzi, kuyeretsa mpweya, komanso ngati chothandizira.
Chimodzi mwazofunikira kwambiri za aluminiyamu activated ndi njira zochizira madzi. Kuchuluka kwake kumapangitsa kuti azitha kutsatsa bwino zonyansa, zitsulo zolemera, ndi zonyansa zina zamadzi. Aluminiyamu yoyendetsedwa ndiyothandiza kwambiri pochotsa fluoride, arsenic, ndi selenium, ndikupangitsa kuti ikhale chida chofunikira kwa madera omwe akukumana ndi zovuta zamadzi. Zomwe zimagwiritsidwa ntchito zimatha kugwiritsidwa ntchito pamabedi okhazikika komanso ma batch, zomwe zimapatsa kusinthasintha pakugwiritsa ntchito kwake. Kuphatikiza apo, alumina yoyendetsedwa imatha kupangidwanso kudzera njira zosavuta zotsuka, zomwe zimapangitsa kukhala njira yotsika mtengo yoyeretsa madzi kwa nthawi yayitali.
Kuphatikiza pa chithandizo chamadzi, alumina yoyendetsedwa imagwiritsidwa ntchito kwambiri pamakina oyeretsa mpweya. Kuthekera kwake kutsatsa chinyontho ndi ma organic organic compounds (VOCs) kumapangitsa kukhala chisankho chabwino kwa ma desiccants ndi zosefera za mpweya. Aluminium yoyatsidwa imatha kuthandizira kuwongolera chinyezi m'malo osiyanasiyana, kuyambira kumafakitale kupita kumalo okhalamo. Pochotsa chinyezi chochulukirapo kuchokera mumlengalenga, zimalepheretsa kukula kwa nkhungu ndi mildew, zomwe zimapangitsa kuti mpweya wabwino wamkati ukhale wabwino. Kuphatikiza apo, aluminiyamu yoyendetsedwa nthawi zambiri imagwiritsidwa ntchito polekanitsa mpweya, komwe imathandizira kuchotsa zonyansa zamagesi achilengedwe ndi mpweya wina wamakampani.
Kugwiritsira ntchito kwina kofunikira kwa aluminiyamu yoyendetsedwa ndi monga chothandizira pamachitidwe amankhwala. Malo ake apamwamba komanso kukhazikika kwamafuta kumapangitsa kuti ikhale njira yabwino kwambiri yothandizira zopangira zinthu zosiyanasiyana, kuphatikizapo kuyeretsa petrochemical ndi kupanga mankhwala apadera. Adamulowetsa aluminiyamu akhoza kumapangitsanso mphamvu ya zochita zothandizira popereka malo khola kwa chothandizira yogwira, potero kuonjezera zokolola wonse wa mankhwala ankafuna. Ntchitoyi ndi yofunika kwambiri popanga mafuta ndi mankhwala, pomwe kukhathamiritsa momwe zinthu zikuyendera zimatha kupulumutsa ndalama zambiri komanso kuchepetsa chilengedwe.
Kusinthasintha kwa alumina yoyendetsedwa kumafikira kugwiritsidwa ntchito kwake m'mafakitale azamankhwala ndi zakudya. M'magawo awa, amagwiritsidwa ntchito kutsatsa zonyansa komanso kuyeretsa zinthu. Aluminium yolumikizidwa imatha kuthandizira kuwonetsetsa chitetezo ndi mtundu wamankhwala ndi zakudya pochotsa zowononga zomwe zingasokoneze kukhulupirika kwawo. Chikhalidwe chake chosakhala ndi poizoni komanso kutsata malamulo kumapangitsa kuti ikhale chisankho chokondedwa pakugwiritsa ntchito komwe kuyeretsedwa kwazinthu ndikofunikira.
Pomaliza, alumina yoyendetsedwa ndi chinthu chothandiza kwambiri komanso chosunthika chomwe chili ndi ntchito zingapo m'mafakitale osiyanasiyana. Makhalidwe ake apadera, kuphatikizapo porosity yapamwamba, luso lapamwamba la adsorption, ndi kukhazikika kwa kutentha, kumapangitsa kukhala gwero lamtengo wapatali lothandizira madzi, kuyeretsa mpweya, chithandizo chothandizira, ndi zina. Pamene mafakitale akupitiliza kufunafuna mayankho okhazikika komanso ogwira mtima kuti athane ndi zovuta zachilengedwe komanso zowongolera, kufunikira kwa alumina yoyendetsedwa ikuyembekezeka kukula. Kuthekera kwake kupititsa patsogolo chitetezo chazinthu ndi chitetezo pomwe ikuthandizira malo oteteza chilengedwe kunayambitsa alumina ngati gawo lofunikira kwambiri m'tsogolomu pantchito zamafakitale.
