Tsananguro pfupi

Bauxite chicherwa chechisikigo, chakaoma zvikuru uye chinonyanya kuumbwa nealuminium oxide compounds (alumina), silica, iron oxides uye titanium dioxide. Inenge 70 muzana yebauxite inogadzirwa pasi rose inonatswa kuburikidza nemaitiro emakemikari ebayer kuita alumina.

Zvichibva pakuti bauxite clinker ine thermal conductivity diki uye iri nani skid resistance uye inodzivirira kupfeka, inogona kushandiswa muHFST (high friction surface treatment) kana abrasion layer yeasphalt musanganiswa kutsiva kana kutsiva chikamu chiripo. Bauxite clinker yakakamurwa kuita mhando nhanhatu zvichienderana nemakemikari akasiyana aripo. Kusarudzwa kwebauxite clinker se aggregate hakusi kungotarisa kukosha kwehupfumi chete, asiwo kuvandudza adhesion pakati pe aggregate neasphalt, iyo ine upofu hwakati. Chidzidzo ichi chakaongorora hunhu hwemhando dzakasiyana dzebauxite clinker. Kubatana kwemhando dzakasiyana dzebauxite clinker neasphalt kwakaongororwa nenzira ye agitating hydrostatic adsorption method uye surface free energy theory. Mhedzisiro yecharacteristic parameters yebauxite clinker pakunamira yakaongororwa ne grey correlation entropy analysis.

Ruzivo rwakadzama

Bauxite ndiyo chinhu chakakodzera pakugadzira alumina. Kunze kwezvinhu zvikuru zviri mualuminium nesilicon, bauxite inowanzobatanidzwa nezvinhu zvakawanda zvinokosha zvakaita segallium (Ga), titanium (Ti), scandium (Sc), uye lithium (Li). Bauxite residue uye circulating spent liquor mukugadzirwa kwealumina zvinowanzo sanganisira zvinhu zvakakosha, zvichiita kuti zvive chinhu chinogona kuva polymetallic. Kudzorerwa kwezvinhu izvi zvakakosha kunogona kuwedzera zvakanyanya kushanda kwekugadzira alumina ukuwo kuchideredza mutoro weindasitiri uye kukanganisa nharaunda. Chidzidzo ichi chinopa ongororo yakakosha yetekinoroji iripo inoshandiswa kudzosa zvinhu zvinokosha kubva ku bauxite residue uye circulating spent liquor kuti ipe ruzivo rwakakura pamusoro pekushandiswa kwakakura kwe bauxite residue sechinhu kwete marara. Kuenzanisa kwezvinhu zviripo zvinoratidza kuti maitiro akabatanidzwa ekudzosa zvinhu zvinokosha uye kuderedza kubudiswa kwemarara kunobatsira.
