Kodi pali kusiyana kotani pakati pa bauxite yaiwisi ndi bauxite yophika?
Dziko langa ndilopanga kwambiri komanso limatumiza kunja kwa zinthu zokanira, zomwe zimapanga 65% yazinthu zonse zapadziko lonse lapansi. Bauxite ndi imodzi mwazinthu zazikulu zopangira zopangira zopangira. Bauxite mu makampani otsutsa nthawi zambiri amatanthauza miyala ya bauxite yokhala ndi calcined Al2O3 zomwe zili ≥48% ndi Fe2O3 yochepa. Monga zofunika zopangira zipangizo refractory, bauxite ali irreplaceable udindo.
Kusiyana kwakukulu pakati pa bauxite yaiwisi yaiwisi ndi bauxite yophika ndi mitundu yosiyanasiyana ya mchere: zopangira ndi kaolinite ndi diaspore, ndipo clinker ndi mullite. Bauxite clinker, yomwe imatchedwa kuti alumina yapamwamba, njerwa zambiri za alumina zopangidwa kuchokera ku clinker yake ndi zipangizo zotsutsa kapena zowonongeka zomwe zimagwiritsidwa ntchito kwambiri m'makampani azitsulo ndi mafakitale ena, makamaka zomwe zimagwiritsidwa ntchito pamwamba pa ng'anjo zamagetsi, ng'anjo zophulika ndi ng'anjo zotentha zotentha. . The refractory effect ndi yofunika kwambiri, ndipo ntchito yake ndi yabwino kuposa njerwa wamba wadongo refractory. Bauxite: aluminiyamu okusayidi ore ndi chilinganizo mankhwala Al2O3.H2O, Al2O3.3H2O ndi pang'ono FE2O3.SiO2. Nthawi zambiri imakhala yachikasu kufiira chifukwa imakhala ndi iron oxide, motero imatchedwanso "iron vanadium nthaka". Ndilo chopangira chachikulu chosungunulira aluminiyamu. Bauxite lagawidwa mu kalasi metallurgical, mankhwala kalasi, refractory kalasi, akupera kalasi, simenti kalasi, etc. malinga ndi ntchito yake.
Amagwiritsidwa ntchito popanga zida zodzitchinjiriza, mtundu uwu wa bauxite umatchedwa refractory grade alumina.
Alumina clinker yokhala ndi magawo oyenera a AL2O3/Fe2O3 ndi AL2O3/SiO2 amagwiritsidwa ntchito kusungunula alumina·/Fe2O3 ndi AL2O3/SiO2.
Bauxite clinker imatha kusinthidwa kukhala zophatikizika ndikugwiritsidwa ntchito ngati zida zokanira monga chitsulo ndi ng'anjo. 5. Ikhoza kusinthidwa kukhala ufa wabwino kuti ugwiritsidwe ntchito poponya, zokutira zokanira ndi mafakitale ena. Itha kugwiritsidwanso ntchito pokonzekera madzi oyeretsera polyaluminium ferric chloride.
