Eyona nto iphambili kwi-activated alumina desiccant yi-industrial grade aluminium hydroxide powder, eluhlobo lwe-basic oxide enomxholo wamanzi oyi-3-5%, kwaye ukutsha kwe-alumina hydroxide kuncitshiswa kwi-900-1100℃ yi-34.5%.
Inkqubo yokuvelisa i-desiccant ye-alumina esebenzayo yile ilandelayo:
I-aluminium hydroxide – ukomisa – isigayo ukuya kwi-600 mesh, i-aluminium hydroxide 300 ℃ ngokukhawuleza kokuphelelwa ngamanzi – ukubumba idiski – unyango lokuvula lweeyure ezili-12 – ngokusebenzisa i-shaft oven 550 ℃ sintering.
1. Umgubo we-aluminium hydroxide wemizi-mveliso, oqulethe ukufuma kwe-3-5%, womiswa kwi-120℃ ngezixhobo ezinkulu zokomisa.
2. Emva kokomiswa, umgubo we-aluminium hydroxide ungena kwi-grinding enkulu yoomatshini kwaye utyumze ukuya kwi-600 meshes. Okukhona ubuncinci buncinci, kokukhona kulunge ngakumbi ukuyibumba ibe yinkqubo yokuqalisa ibhola. Amasuntswana angqukuva avelisiweyo akanawo umgubo kwaye anamandla aphezulu.
3, i-aluminium hydroxide egayiweyo, ingena kwinkqubo yokukhupha igesi ngokukhawuleza ukuze iqale ukucocwa, i-aluminium hydroxide egayiweyo ibe ngumgubo ocolekileyo emoyeni oshushu kakhulu ohlala u-0.10s, umgaqo wemveliso ngulo: i-aluminium hydroxide ngokuyimisa, ukuyosa ngokukhawuleza, kunye nokupholisa ngokukhawuleza.
4, kusetyenziswa umgaqo we-snowball, ukuveliswa kwebhola ye-alumina esebenzayo, le nkqubo ingenziwa ngobubanzi obahlukeneyo be-desiccant ye-alumina esebenzayo kunye nomthwali.
5, ibhola yamasuntswana e-alumina asebenzayo ayitshintshi kangangeeyure ezili-12, ubushushu bayo kunye namanzi ukuze isebenze.
6. Okokugqibela, i-alumina esebenzayo itshizwa kwi-oven ethe nkqo, kwaye ubushushu bokurosa buyi-550-700℃.
