Activated alumina chinhu chakanyanya porous uye chinogoneka chakatorwa kubva kualuminium oxide (Al2O3). Iyo inogadzirwa kuburikidza nekupera mvura kwealuminium hydroxide, zvichikonzera chinhu chegranular chine nzvimbo yakakwirira uye yakanakisa adsorption zvimiro. Uku kusanganisa kwakasarudzika kwehunhu kunoita kuti alumina yakabatidzwa ive chinhu chakakosha mumaindasitiri akasiyana ekushandisa, kusanganisira kurapwa kwemvura, kucheneswa kwemhepo, uye serutsigiro runobatsira.
Imwe yeanonyanya kukosha mashandisirwo eakamisikidzwa alumina ari mumagadzirirwo emvura. Yayo yakakwirira porosity inobvumira kuti inyatso kushambadzira tsvina, heavy metals, uye zvimwe zvinosvibisa kubva mumvura. Activated alumina inonyanya kushanda mukubvisa fluoride, arsenic, uye selenium, zvichiita kuti ive sosi yakakosha kunharaunda dzinotarisana nedambudziko remvura. Izvo zvinhu zvinogona kushandiswa mune zvese zvakagadziriswa-mubhedha uye batch maitiro, zvichipa kuchinjika mukushandisa kwayo. Uyezve, yakabatidzwa alumina inogona kuvandudzwa kuburikidza neakareruka maitiro ekugeza, zvichiita kuti ive inodhura-inoshanda mhinduro yekunatswa kwemvura kwenguva refu.
Pamusoro pekurapwa kwemvura, activated alumina inoshandiswa zvakanyanya mumhepo yekuchenesa masisitimu. Kugona kwayo kushambadza unyoro uye kuvhuvhuta organic compounds (VOCs) inoita kuti ive sarudzo yakanaka kune desiccants uye mafirita emhepo. Activated alumina inogona kubatsira kudzora humidity mazinga munzvimbo dzakasiyana siyana, kubva kumaindasitiri ezvirongwa kusvika kunzvimbo dzekugara. Nekubvisa mwando wakawandisa kubva mumhepo, zvinodzivirira kukura kwe mold uye mildew, zvichibatsira kune hutano hwemukati memhepo kunaka. Uyezve, yakagadziriswa alumina inowanzo shandiswa mumagasi ekuparadzanisa maitiro, uko inobatsira kubvisa kusvibiswa kubva kugasi rechisikigo uye mamwe magasi emaindasitiri.
Kumwe kuomesesa kwekushandisa kweakamisikidzwa alumina kwakafanana nerutsigiro runotsigira mukuita kwemakemikari. Nzvimbo yayo yepamusoro yepamusoro uye kugadzikana kwekupisa kunoita kuti ive yakanakisa svikiro yekutsigira zvinokonzeresa mune akasiyana maitiro, kusanganisira petrochemical refining uye kugadzirwa kweakakosha makemikari. Activated alumina inogona kukwidziridza kushanda kwecatalytic reactions nekupa yakagadzikana nzvimbo yeinoshanda catalyst, nekudaro ichiwedzera goho rese rechigadzirwa chaunoda. Chishandiso ichi chakanyanya kukosha mukugadzirwa kwemafuta nemakemikari, uko kugadzirisa mamiriro ekuita kunogona kutungamira mukukosheswa kwemutengo uye kuderedzwa kwezvakatipoteredza.
Iko kuita kwakasiyana-siyana kweakamisikidzwa alumina kunosvika pakushandiswa kwayo mumishonga yemishonga uye maindasitiri ezvekudya zvakare. Muzvikamu izvi, rinoshandiswa kushambadza tsvina uye kucheneswa kwezvigadzirwa. Activated alumina inogona kubatsira kuchengetedza uye kunaka kwemishonga uye zvigadzirwa zvekudya nekubvisa zvinosvibisa zvinogona kukanganisa kuvimbika kwavo. Hunhu hwayo husina chepfu uye kutevedza kwemitemo kunoita kuti ive sarudzo inosarudzika kune maapplication uko kuchena kwechigadzirwa kwakakosha.
Mukupedzisa, activated alumina chinhu chinoshanda zvakanyanya uye chinogoneka chine huwandu hwakasiyana hwekushandisa mumaindasitiri akasiyana siyana. Hunhu hwayo hwakasiyana, hunosanganisira yakakwira porosity, yakanakisa adsorption kugona, uye kugadzikana kwekupisa, inoita kuti ive yakakosha sosi yekurapwa kwemvura, kucheneswa kwemhepo, tsigiro inokonzeresa, nezvimwe. Sezvo maindasitiri achiramba achitsvaga mhinduro dzakasimba uye dzakasimba dzekusangana nemamiriro ekunze uye ekudzora matambudziko, kudiwa kwealumina yakagadziriswa kunotarisirwa kukura. Kugona kwayo kukwidziridza kunaka kwechigadzirwa uye kuchengetedzeka uku uchibatsira kunzvimbo dzekuchengetedza nharaunda yakagadziriswa alumina semutambi akakosha mune ramangwana rekushandisa kwemaindasitiri.
