Aluminium hydroxide ntau lawm cuam tshuam feem ntau cuam tshuam nrog cov sodium aluminate txheej txheem, cov pa roj carbon fractives, thiab cov txheej txheem bayer.
1. Sodium aluminate txheej txheem
Cov kua sodium aluminate tov yog neutralized nrog txhuas sulfate mus rau lub p ntawm 6,5 los tsim cov tshuaj txhuas hydroxide. Cov khoom yog tom qab ntawd siv, ntxuav, thiab qhuav kom tau cov khoom.
2. Carbon Fractionation Txheej Txheem
Cov pa roj carbon dioxide tau qhia rau hauv cov sodium aluminate daws los ua cov txhuas hydroxide nag lossis daus. Cov txheej txheem no tso cai rau cov particle loj ntawm cov khoom yuav tsum tau hloov kho los ntawm kev tswj hwm cov nyiaj ntawm cov pa roj carbon dioxide.
3. Bayer txheej txheem
Aluminium hydroxide yog cov khoom nruab nrab muab rho tawm los ntawm bauxite thiab tom qab ntawd calcined los tsim alumina. Raws li cov khoom nruab nrab hauv cov txheej txheem no, kev ua kom huv huv ntawm txhuas hydroxide ncaj qha cuam tshuam qhov zoo ntawm alumina kawg.
