1. Kufotokozera za mankhwala a boehmite omwe akuperekedwa: Mankhwalawa ndi osakhala ndi poizoni, opanda kukoma komanso opanda fungo. Mankhwalawa ndi oyera ndipo ufa wouma ndi ufa woyera. Kukula kwa ma pore ndi kofanana, kuchuluka kwake ndi kwakukulu ndipo madzi amayamwa bwino. Ali ndi kuyera kwa radial, magwiridwe antchito abwino komanso mawonekedwe abwino a thixotropic gel. Mankhwalawa amatha kusungunuka bwino, ndi osavuta kusungunuka mu asidi wamphamvu ndi alkali, ndipo ali ndi magwiridwe antchito abwino.
2. Kukonza ndi kusunga pseudo boehmite: pseudo boehmite imayikidwa m'matumba opangidwa ndi nsalu. Sungani m'nyumba yosungiramo zinthu yozizira, yopuma mpweya wabwino komanso youma.
3. Ntchito zazikulu za boehmite zomwe zikuperekedwa:
Chogulitsachi chimagwiritsidwa ntchito makamaka ngati zinthu zopangira alumina yothandizira, monga zinthu zopangira hydrogenation, zothandizira hydrogenation ndi oxychlorination.
Ingagwiritsidwenso ntchito ngati chomangira chopangira zinthu za zeolite ndi silicate refractory fiber, monga chomangira chopangira zinthu zosakaniza za rare earth Y zeolite.
Chogulitsachi ndi chinthu chabwino kwambiri popanga mchere wosiyanasiyana wa aluminiyamu. Pambuyo pochiumba, chingagwiritsidwe ntchito ngati desiccant, adsorbent komanso catalyst carrier yokhala ndi mawonekedwe osiyanasiyana.
1. Kusankha bwino zida zotsukira ndi kusefa pogwiritsa ntchito fyuluta ya vacuum lamba yokhazikika ya chipinda chosungiramo madzi ndiyo njira yochepetsera kugwiritsa ntchito madzi abwino popanga pseudo boehmite.
2. Njira yachitatu yotsukira imagwiritsidwa ntchito posakaniza sodium aluminate solution kuti ichepetse kusuntha kwakunja ndikuwonjezera kugwiritsa ntchito bwino madzi atsopano. Ndi njira yofunika kwambiri yochepetsera kugwiritsa ntchito madzi atsopano.
3. Njira yaikulu yochepetsera kugwiritsa ntchito madzi atsopano ndikuwonjezera kutentha koyenera kwa madzi otentha, kupanga njira yoyenera yogwirira ntchito ndikugwiritsa ntchito njira yoziziritsira yogawika m'magulu.
Pseudo boehmite ndi mtundu wa pseudo boehmite yokhala ndi colloidal crystallization yosakwanira. Zogulitsa 1, zopanda poizoni, 2, zopanda kukoma, 3, zopanda fungo, 4, crystalline phase high purity, 5, kusungunuka bwino, 6, kumatirira mwamphamvu, 7, yokhala ndi makhalidwe a thixotropic gel. Pseudo boehmite ingagwiritsidwe ntchito kwambiri mu petrochemical, feteleza wa mankhwala, zinthu za silicate, kuteteza chilengedwe ndi mafakitale ena.
