Alumina yakakamurwa chinhu chine maburi akawanda uye chinobatika chinobva kualuminium oxide (Al2O3). Chinogadzirwa kuburikidza nekushaya mvura mumuviri kwealuminium hydroxide, zvichikonzera chinhu chine granular chine nzvimbo yakakwirira uye hunhu hwakanaka hwekusveta mvura. Musanganiswa uyu wehunhu hwakasiyana unoita kuti alumina yakakamurwa ive chinhu chakakosha mumaindasitiri akasiyana-siyana, kusanganisira kurapwa nemvura, kucheneswa kwemhepo, uye sechinotsigira catalyst.
Imwe yenzira dzakakosha dzekushandisa activated alumina ndeyekugadzirisa mvura. Kuwanda kwayo kunoibvumira kuti ikwanise kubvisa tsvina, simbi dzinorema, nezvimwe zvinosvibisa kubva mumvura. Alumina inoshanda zvakanyanya mukubvisa fluoride, arsenic, uye selenium, zvichiita kuti ive chinhu chinokosha kune nharaunda dziri kusangana nematambudziko emhando yemvura. Chinhu ichi chinogona kushandiswa mumatanho ekugadzirisa mvura akasimba uye emhando dzakasiyana, zvichipa mukana wekushandisa nyore nyore. Uyezve, activated alumina inogona kugadzirwazve kuburikidza nemaitiro ari nyore ekugeza, zvichiita kuti ive mhinduro inodhura yekuchenesa mvura kwenguva refu.
Pamusoro pekurapa nemvura, alumina inoshandiswa zvakanyanya mukuchenesa mweya. Kugona kwayo kunyudza hunyoro nemakemikari anonyungudika (VOCs) kunoita kuti ive sarudzo yakanaka yekubvisa hunyoro nemafuta anofefetera mweya. Alumina inoshandiswa inogona kubatsira kudzora hunyoro munzvimbo dzakasiyana-siyana, kubva kumaindasitiri kusvika kunzvimbo dzekugara. Nekubvisa hunyoro hwakawandisa mumhepo, inodzivirira kukura kwefungus nefungus, zvichibatsira kuti mhepo yemukati ive yakanaka. Uyezve, alumina inoshandiswa inowanzo shandiswa mukuita kwekuparadzanisa magasi, uko inobatsira kubvisa tsvina kubva mugasi rechisikigo nemamwe magasi emuindasitiri.
Imwe nzira yakakosha yekushandisa alumina yakakamurwa ndeyekutsigira mashandiro emakemikari. Nzvimbo yayo yepamusoro uye kugadzikana kwekupisa kunoita kuti ive nzvimbo yakanaka yekutsigira ma catalyst mumabasa akasiyana-siyana, kusanganisira kugadzirisa petrochemical uye kugadzira makemikari akakosha. Alumina yakakamurwa inogona kuwedzera kushanda kwe catalytic reactions nekupa nzvimbo yakagadzikana ye active catalyst, nokudaro ichiwedzera goho remuchigadzirwa chaunoda. Kushandiswa uku kwakakosha zvikuru mukugadzirwa kwemafuta nemakemikari, uko kugadzirisa mamiriro e reaction kunogona kutungamira mukuchengetedza mari yakawanda uye kuderedza kukanganisa kwezvakatipoteredza.
Kushandiswa kwakasiyana-siyana kwealumina yakakamurwa kunosvika pakushandiswa kwayo mumaindasitiri emishonga nekudya. Muzvikamu izvi, inoshandiswa pakunyungudutsa tsvina uye kuchenesa zvigadzirwa. Alumina yakakamurwa inogona kubatsira kuona kuchengetedzeka uye kunaka kwemishonga nezvigadzirwa zvekudya nekubvisa tsvina inogona kukanganisa kunaka kwayo. Hunhu hwayo husina chepfu uye kutevedzera mitemo kunoita kuti ive sarudzo inosarudzwa pakushandiswa uko kuchena kwechigadzirwa kuri kukuru.
Mukupedzisa, alumina yakakamurwa chinhu chinoshanda zvikuru uye chinoshanduka-shanduka chine mashandisirwo akasiyana-siyana mumaindasitiri akasiyana-siyana. Hunhu hwayo hwakasiyana, kusanganisira maburi akawanda, kugona kwayo kunyudza mvura zvakanaka, uye kugadzikana kwekupisa, zvinoita kuti ive chinhu chakakosha pakurapa mvura, kuchenesa mhepo, kutsigira catalyst, nezvimwewo. Sezvo maindasitiri achiramba achitsvaga mhinduro dzinogara kwenguva refu uye dzinoshanda kuti asangane nematambudziko ezvakatipoteredza nemitemo, kudiwa kwealumina yakakamurwa kunotarisirwa kukura. Kugona kwayo kusimudzira mhando yechigadzirwa nekuchengetedzeka uku ichibatsira munzvimbo dzekuchengetedza zvakatipoteredza yakakamurwa semutambi mukuru mune ramangwana remashandisirwo emaindasitiri.
