Ua kom Alumina yog tsim kev siv ob cov khoom siv raw: "Lub cev qhuav dej" uas tsim los ntawm Gibblesite lossis Bayero {}} Cov ntsev, lossis cov ntsev tsis zoo, lossis ob qho tib si.
X {{0} ρ ρ ρ alumin ntau lawm
X - ρ alumination ρ alumin yog thawj cov ntaub ntawv raw rau cov khoom lag luam alumina pellets. Nws yog luv luv li FCA txawv teb chaws thiab raug xa mus rau "Lub cev qhuav dej ceev" hauv Suav teb vim tias nws yog alumina hmoov tsim kev siv cov txheej txheem rhohydration sai. "Lub cev qhuav dej ceev ceev" yog qhov sib xyaw ntawm x {}} alumina thiab rhe {} alumina, nrog cov ntsiab lus sib txawv nyob ntawm cov xwm txheej ntau lawm.
Pseudo -} behmite ntau hom
Ntuj los yog kev tsim txom alumina monohydate thiab alumina trihydrate tsis tuaj yeem siv los ua cov neeg desiccants, catalystions, lossis cov khoom siv catalyst ntau, lossis cov khoom siv pore me me, thiab cov haujlwm tsawg. Alumina monohydrate lossis alumina trihydrate yuav tsum tau ua rau hauv pseudo - bohmite. Pseudo - boehmite muaj qhov chaw siab tshwj xeeb, kev ua haujlwm loj, thiab cov tshuaj tua kab mob catalyst, thiab cov tshuaj tua kab mob catalynent, thiab tso pa tawm.
