Kufotokozera Kwachidule

Bauxite ndi mchere wachilengedwe komanso wolimba kwambiri ndipo makamaka umapangidwa ndi zinthu za aluminiyamu oxide (alumina), silica, iron oxides ndi titanium dioxide. Pafupifupi 70 peresenti ya bauxite yomwe imapezeka padziko lonse lapansi imayengedwa kudzera mu njira ya mankhwala ya bayer kukhala alumina.

Kutengera mfundo yakuti bauxite clinker ili ndi kutentha pang'ono komanso kukana kutsetsereka bwino komanso mphamvu yolimbana ndi kutopa, ingagwiritsidwe ntchito mu HFST (kuchiza pamwamba pa kupsinjika kwakukulu) kapena kusakanizidwa kwa chisakanizo cha asphalt kuti ilowe m'malo kapena kusintha pang'ono aggregate yomwe ilipo. Bauxite clinker imagawidwa m'magulu asanu ndi limodzi makamaka malinga ndi kapangidwe ka mankhwala osiyanasiyana. Kusankhidwa kwa bauxite clinker ngati aggregate sikungokhudza phindu lachuma, komanso kukonza kumamatirana pakati pa aggregate ndi asphalt, komwe kuli ndi khungu linalake. Kafukufukuyu adawunika makhalidwe a mitundu yosiyanasiyana ya bauxite clinker. Kumamatirana kwa mitundu yosiyanasiyana ya bauxite clinker ndi asphalt kudawunikidwa pogwiritsa ntchito njira yolimbikitsa hydrostatic adsorption ndi chiphunzitso cha mphamvu yopanda pamwamba. Zotsatira za magawo a bauxite clinker pa adhesion zidawunikidwa ndi kusanthula kwa imvi correlation entropy.

Zambiri zatsatanetsatane

Bauxite ndi chinthu chabwino kwambiri popanga alumina. Kupatula zinthu zazikulu zomwe zimapangidwa ndi aluminiyamu ndi silicon, bauxite nthawi zambiri imagwirizanitsidwa ndi zinthu zambiri zamtengo wapatali monga gallium (Ga), titanium (Ti), scandium (Sc), ndi lithiamu (Li). Zotsalira za bauxite ndi mowa wogwiritsidwa ntchito popanga alumina nthawi zambiri zimakhala ndi zinthu zamtengo wapatali zambiri, zomwe zimapangitsa kuti zikhale gwero la polymetallic. Kubwezeretsa zinthu zofunikazi kumatha kuwonjezera kwambiri magwiridwe antchito opangira alumina komanso kuchepetsa mavuto a mafakitale komanso chilengedwe. Kafukufukuyu akupereka kusanthula kofunikira kwa ukadaulo womwe umagwiritsidwa ntchito pobwezeretsa zinthu zamtengo wapatali kuchokera ku zotsalira za bauxite ndi mowa wogwiritsidwa ntchito kuti apereke chidziwitso pakugwiritsa ntchito kwambiri zotsalira za bauxite ngati chuma m'malo motaya. Kuyerekeza kwa zinthu zomwe zilipo kale kukuwonetsa kuti njira yolumikizirana yobwezeretsa zinthu zamtengo wapatali ndi kuchepetsa kutulutsa zinyalala ndi yopindulitsa.
