Izinto eziyinhloko zokusetshenziswa kwe-alumina desiccant esebenzayo yi-industrial grade aluminium hydroxide powder, okuwuhlobo lwe-oxide eyisisekelo enokuqukethwe kwamanzi okungu-3-5%, kanti ukwehla kokusha kwe-alumina hydroxide ku-900-1100℃ kungu-34.5%.
Inqubo yokukhiqiza i-desiccant ye-alumina esebenzayo yile elandelayo:
I-aluminium hydroxide – ukomisa – isigayo sibe yi-mesh engu-600, i-aluminium hydroxide engu-300 ℃ yokuphelelwa amanzi ngokushesha – ukubumba amadiski – ukwelashwa kokusebenza kwamahora ayi-12 – ngokusebenzisa i-shaft kiln engu-550 ℃ evuthayo.
1. Impuphu ye-aluminium hydroxide yezimboni, equkethe umswakama ongu-3-5%, yomiswa ku-120℃ ngemishini emikhulu yokomisa.
2. Ngemva kokomiswa, i-aluminium hydroxide powder ingena ekugayweni okukhulu komshini bese ichoboza ibe yi-meshes engu-600. Uma ubuncane buncane, kulapho kulungele khona ukubumba inqubo yokwenza ibhola isebenze. Izinhlayiya eziyindilinga ezikhiqizwayo azinawo umpunga futhi zinamandla aphezulu.
3, i-aluminium hydroxide ewuphuphu, ingena ohlelweni lokususa igesi ngokushesha ukuze kuqale ukusha, i-aluminium hydroxide ewuphuphu omuhle emoyeni oshisayo oshisayo ohambayo kakhulu ihlale imizuzwana engu-0.10, isimiso sokukhiqiza yilesi: i-aluminium hydroxide ngokumiswa kokubhaka amanzi ngokushesha, kanye nokupholisa okusheshayo.
4, kusetshenziswa isimiso se-snowball, ukukhiqizwa kwebhola le-alumina elisebenzayo, le nqubo ingenziwa ngobubanzi obuhlukene be-desiccant ye-alumina esebenzayo kanye ne-carrier.
5, ibhola lezinhlayiya ze-alumina ezisebenzayo lihlala amahora ayi-12, lishisa futhi lisebenzise amanzi ukuze lisebenze.
6. Ekugcineni, i-alumina esebenzayo ifakwa kuhhavini oqondile, bese izinga lokushisa lokuthosa lingu-550-700℃.
