Babban kayan albarkatun ƙasa na alumina desiccant da aka kunna shine foda hydroxide na masana'antu, wanda shine nau'in oxide na asali tare da abun ciki na ruwa 3-5%, kuma raguwar ƙonewar alumina hydroxide a 900-1100 ℃ shine 34.5%.
Tsarin samar da sinadarin alumina mai aiki kamar haka:
Aluminum hydroxide - busarwa - niƙa zuwa raga 600, aluminum hydroxide 300 ℃ bushewa cikin sauri - ƙera faifai - maganin kunnawa na awanni 12 - ta hanyar murhun shaft 550 ℃ sintering.
1. Ana busar da foda na aluminum hydroxide na masana'antu, wanda ke ɗauke da danshi 3-5%, a zafin 120℃ ta hanyar manyan kayan aikin busarwa.
2. Bayan bushewa, foda na aluminum hydroxide yana shiga cikin manyan niƙa na inji kuma yana niƙa har zuwa raga 600. Mafi ƙanƙantar da kyau, mafi kyawun siffantawa zuwa tsarin kunna ƙwallon. Ƙwayoyin da aka samar ba su da foda da ƙarfi mai yawa.
3, foda aluminum hydroxide, cikin tsarin rage gas mai sauri don fara sintering, foda mai laushi na aluminum hydroxide a cikin iska mai zafi mai cike da rudani yana tsayawa 0.10s, ƙa'idar samarwa ita ce: aluminum hydroxide ta hanyar dakatarwa gasa bushewa cikin sauri, da kuma sanyaya cikin sauri.
4, ta amfani da ƙa'idar ƙwallon dusar ƙanƙara, samar da ƙwallon alumina mai kunnawa, wannan tsari za a iya yin shi da diamita daban-daban na ma'aunin alumina mai kunnawa da mai ɗaukar kaya.
5, ƙwallon ƙwayoyin alumina da aka kunna suna tsayawa na tsawon awanni 12, zafinsa da ruwansa don kunnawa.
6. A ƙarshe, ana sanya alumina mai aiki a cikin murhu a tsaye, kuma zafin gasawa shine 550-700℃.
