Kufanana nekabhoni yakakangwa, nzvimbo yakakwirira uye porosity inoratidzwa nealumina yakakangwa inobvumira kuti ibate uye ibate mhando dzakasiyana dzezvinhu, zvichiita kuti ishandiswe semushonga unokwevera mvura, desiccant, nezvimwewo. Nzira huru dzinoshandiswa nezvigadzirwa zvealumina zvakakangwa dzinosanganisira:
ZVINHU ZVINOVHURA
Alumina inoshanda zvikuru mukubvisa zvinhu kubva mumhepo nemafuta, uye nekudaro, inoshandiswa nemaindasitiri akati wandei kubvisa zvinhu kubva kune zvimwe zvinhu.
Semushonga unonamira mvura, alumina inonamira mvura inozivikanwa zvikuru nekunamira kwayo mukuchenesa mvura, uko inoshanda semushonga unonamira mvura usingadhuri pakubvisa fluoride mumvura. Inokwanisawo kubvisa zvimwe zvinhu zvakasiyana-siyana zvinosvibisa mvura, zvinosanganisira arsenic, lead, uye sarufa.
CHINODYA MUKUVHARA
Kufanana nebasa rayo semushonga wekukweva mvura, alumina yakakamurwa inogonawo kukweva mvura kubva mumhepo, zvichiita kuti ishandiswe semushonga wekukweva mvura; alumina yakakamurwa inogona kubata nekubata mvura kuitira kuti zvinhu zvisaome, sezvinoita silica gel. Semushonga wekukweva mvura, alumina yakakamurwa inogona kukweva kusvika 20% yehuremu hwayo mumvura ine hunyoro hwe50%.
Alumina inoshandiswa pakuchenesa inoshandiswa pakubvisa utsi hwemvura mumagasi munzvimbo dzakasiyana-siyana, kusanganisira kubvisa utsi hwemvura kubva mumagasi munzvimbo dzemaindasitiri. Mvura inonamirwa paalumina inoshandiswa pakuchenesa inogona kubviswa kuburikidza nekupisa uye alumina inoshandiswazve.
ZVINOKWEZVAKA
Alumina yakabatidzwa inoshandiswawo zvakanyanya sechinhu chinobatsira pakugadzira zvinhu, iine mabasa ekugadzira zvinhu, pamwe chete nechinotakurwa chisina simba, kana kuti chinhu chinobatsira pakugadzira zvimwe zvinhu.
Sechinokonzeresa, alumina yakakamurwa inozivikanwa zvikuru nebasa rayo sechinokonzeresa cheClaus; alumina yakakamurwa ndiyo inonyanya kushandiswa mukutsvaga sarufa munzvimbo dzinocheneswa mafuta negasi.
MHEDZISO
Nekuda kwekugona kwayo semushonga unonyungudutsa, unobvisa mvura, uye unokonzeresa kusvibiswa, alumina inoshandiswa muindasitiri inoshandiswa zvakanyanya. Yakagadzirwa kubva mukushanda kwealuminium oxide inobva muBayer process kuburikidza ne calcination, alumina inoshandiswa inogona kugadziriswa zvakanyanya uye inowanzobatanidzwa kuti ivandudze mashandiro uye hunhu hwekubata. Kuedza kugona kwayo kunowanzova chinhu chinobatsira pakushanda nezvigadzirwa zvealumina zvinoshandiswa muindasitiri.
