Amatafari ya Alumina yo mu rwego rwo hejuru: Abarinzi bizerwa b'inganda zikoresha ubushyuhe bwinshi

Mu rwego rw'inganda zikoresha ubushyuhe bwinshi, imikorere y'ibikoresho igena mu buryo butaziguye uburyo umusaruro uhamye n'ubushobozi bwawo.Amatafari menshi ya alumina arwanya ibidukikije, kubera ko ibikoresho byoroshye kandi birekura ibintu bikozwe ahanini muri bauxite ifite alumina nyinshi, byabaye amahitamo meza ku nganda nyinshi zikoresha ubushyuhe bwinshi kubera imikorere yazo myiza, zirinda iterambere ry’ubucukuzi bw’amabuye y’agaciro ku isi, ibikoresho by’ubwubatsi, imiti n’izindi nganda.

Ibyiza by'ingenzi by'amatafari ya alumina menshi ahinduka imiterere yayo idasanzwe bituruka ku buryo bwihariye bwo kuyakora no ku buryo akorwamo. Aya matafari akozwe mu cyuma cya alumina bauxite gifite alumina nyinshi gifite ubunini butari munsi ya 48% nk'umubumbe, hanyuma agashyirwa hamwe n'ibikoresho byo gufunga mu bipimo bitandukanye, hanyuma agakorwa, akanikwa, agashya ku bushyuhe bwinshi. Amatafari ya alumina menshi ahinduka imiterere myiza afite ubukana bwiza bwo guhangana n'ubushyuhe bwinshi kuva kuri 1770°C kugeza 1790°C. Ndetse no mu bidukikije bishyuha cyane, ashobora kugumana ubuziranenge bw'imiterere, akarwanya neza kwangirika k'ubushyuhe bwinshi ku bikoresho. Ubushyuhe bwiza bwo koroshya imitwaro butuma adahinduka cyangwa ngo asenyuke bitewe n'umuvuduko runaka n'ubushyuhe bwinshi, bigatanga icyizere cyizewe cy'imikorere ihamye y'ibikoresho bishyuha cyane. Byongeye kandi, amatafari ya alumina menshi ahinduka imiterere myiza y'ubushyuhe, ibi bikabafasha kugumana imikorere ihamye mu gihe cy'impinduka z'ubushyuhe kenshi, bikagabanya kwangirika no kwangirika guterwa n'ubushyuhe kandi bikongera igihe cyo kuyakoresha. Afite kandi ubudahangarwa bukomeye ku bintu bitandukanye bya chimique. Byaba ari ibintu bihumanya ikirere cyangwa imyuka ihumanya ikirere mu gukora imiti, biragoye kubiteza ingaruka zikomeye.

Amatafari areshya alumina menshi afite akamaro kanini. Mu nganda zikora ibyuma, ni ibikoresho by'ingenzi mu gushyira mu nganda amatanura, amatanura yo gukora ibyuma, n'amatanura yo kongera gushyushya. Ashobora kurwanya neza kwangirika kw'icyuma gishongeshejwe n'ibisigazwa by'ubushyuhe bwinshi, atuma inzira yo gushongesha igenda neza kandi akanoza ubuzima bw'ibikoresho n'umusaruro. Mu nganda zikora ibikoresho by'ubwubatsi, amatafari areshya alumina menshi akunze gukoreshwa mu bikoresho nk'amatanura azunguruka ya sima n'amatanura ashongesha ibirahure. Mu duce dufite ubushyuhe bwinshi, gusya umwuka wihuta, no gushwanyagurika kw'ibikoresho, ashobora gukomeza gukora neza, agashyigikira imikorere ihamye yo gukora ibikoresho by'ubwubatsi. Mu nganda zikora imiti, amatafari areshya alumina menshi agira uruhare runini mu matanura areshya ubushyuhe bwinshi n'ibikoresho bikoresha gazi. Kubera ko arwanya ingese neza, atuma inzira yo gukora imiti ikoreshwa mu buryo bw'ubushyuhe bwinshi ikomeza.

Dufite ibikoresho bigezweho byo gukora ndetse n'uburyo buhamye bwo kugenzura ubuziranenge. Buri sano, kuva ku kugura ibikoresho fatizo kugeza ku gutanga ibicuruzwa byarangiye, ikurikiranwa neza. Mu gukoresha inzira zo gukora zigezweho ku rwego mpuzamahanga, twemeza ko ubuziranenge bw'amatafari afite alumina nyinshi yujuje ibisabwa mpuzamahanga. Muri icyo gihe, dutanga kandi ubufasha bw'umwuga mu bya tekiniki na serivisi zuzuye nyuma yo kugurisha. Dukurikije ibyo abakiriya bakeneye bitandukanye, dutanga ibisubizo byihariye kugira ngo amatafari afite alumina nyinshi akore neza mu bikorwa bifatika.

Guhitamo amatafari yacu arwanya alumina nyinshi bivuze guhitamo ubuziranenge n'ubwizerwe. Waba ukeneye kugura ibikoresho binini cyangwa ibikoresho birwanya, dushobora kuguhaza ibyo ukeneye. Twakira neza abakiriya baturutse impande zose z'isi kugira ngo badusange kandi dufatanye mu guhanga ahazaza heza ku nganda zikoresha ubushyuhe bwinshi!
