Desiccants zvinhu zvinotora hunyoro kubva kunharaunda, zvichiita kuti zvive zvakakosha mumaindasitiri akasiyana-siyana kuchengetedza kuvimbika kwezvigadzirwa uye zvinhu. Pakati peakawanda ma desiccants aripo, yakabatidzwa alumina inomira pachena nekuda kweiyo yakasarudzika zvivakwa uye kuita zvakasiyana.
Activated alumina iine porous fomu yealuminium oxide, yakagadzirwa nekurapa aluminium hydroxide nekupisa. Iyi nzira inosimudzira nzvimbo yayo yepamusoro uye adsorption kugona, zvichiita kuti ive inoshanda desiccant. Iine nzvimbo yepamusoro inosvika 300 m²/g, yakabatidzwa alumina inogona kutora akakosha huwandu hwemhute yemvura, ichiita kuti ive yakanakira maapplication uko kunodzora hunyoro kwakakosha.
Imwe yemashandisirwo ekutanga eakamiswa alumina ari mukuwomeswa kwemagasi uye zvinwiwa. Muzvigadziro zveindasitiri, inowanzo shandiswa kubvisa hunyoro kubva kumhepo yakamanikidzwa uye gasi rechisikigo, kudzivirira kuora uye kuve nechokwadi chekushanda kwemidziyo. Pamusoro pezvo, yakashongedzwa alumina inoshandiswa mukugadzira yakakwira-kuchena makemikari nemishonga, uko kunyangwe huwandu hwemwando hunogona kukanganisa kunaka kwechigadzirwa.
Activated alumina inoitawo basa rakakosha muindasitiri yekurapa mvura. Inoshanda pakubvisa fluoride uye arsenic kubva kumvura yekunwa, zvichiita kuti ive chinhu chakakosha muhurongwa hwekuchenesa mvura. Kugona kwayo kushambadza zvinosvibisa uku uchichengeta yakaderera leaching mwero unova nechokwadi chekuti mvura yakarapwa inoramba yakachengeteka kuti ishandiswe.
Uyezve, yakagadziriswa alumina inogona kushandiswa zvakare. Inogona kuvandudzwa nekupisa, ichibvumira kuti isunungure unyoro hwakabatwa uye kushandiswa kakawanda. Ichi chimiro hachingoiti kuti chiite mari-chinoshanda asiwo chinobatsira zvakatipoteredza, sezvo chinoderedza tsvina inosanganiswa ne-single-use desiccants.
Mukupedzisa, activated alumina ine simba desiccant ine akasiyana maapplication mumaindasitiri akasiyana siyana. Hunyoro hwayo hwekutora hunyoro, hwakasanganiswa nekugona kushandiswazve, hunoita kuti ive chishandiso chakakosha kuchengetedza kunaka kwechigadzirwa uye kuchengetedzeka munzvimbo dzinonzwa hunyoro.
