Amatafari arwanya alumina menshi ni ibikoresho birwanya alumina byinshi kandi bifite alumina irenga 48%. Yakuwe muri bauxite nziza mu bushyuhe bwinshi, irusha amatafari asanzwe y'ibumba mu bushyuhe bwinshi, mu buryo buhamye kandi burwanya ingese. Nk'ibikoresho by'ingenzi byo gushyiramo amatanura mu nganda, ikoreshwa cyane mu byuma, sima, imiti n'ingufu, ikaba igisubizo cyizewe cyo kurinda ibikoresho by'inganda mu bushyuhe bwinshi.
Imiterere y'ingenzi
Iri tafari ridashobora gucikamo ibice rifite imikorere myiza cyane mu nganda zikomeye, rikemura neza ibibazo bisanzwe byo gucikamo ibice by'itanura nko gushwanyagurika, gushishwa no kumara igihe gito rikora.
Ubushyuhe bwa 1750°C kugeza 1800°C. Ubwoko bwiza bushobora kwihanganira ubushyuhe buri hejuru ya 1800°C, bugakomeza gukora neza nta konje cyangwa ngo bushonge mu gihe kirekire bukoreshwa mu bushyuhe bwinshi.
Ubushyuhe bwo koroshya imizigo bwa 1420°C–1500°C burwanya ihindagurika ry'umuvuduko w'umuriro, bugatuma umubiri w'itanura ukomeza gukora neza kandi bukagabanya ibyago byo kwangirika kw'ibikoresho.
Inyubako nziza ya mullite irwanya isuri iterwa n'ibisigazwa by'amazi yashongeshejwe, amazi y'icyuma n'imyuka ihumanya, ikarinda kwangirika kw'inkuta no kongera igihe cyo gukora mu itanura.
Yihanganira ihindagurika ry'ubushyuhe rikabije idacikagurika cyangwa ngo ikureho. Ingufu nyinshi zo gukanda zituma ishobora kwihanganira gukaraba ibikoresho igihe kirekire no gushwanyagurika mu buryo bw'ikoranabuhanga.
Ubushyuhe buke bugabanya igihombo cy'ubushyuhe mu itanura kandi bukongera imikorere myiza y'ingufu. Bigabanya inshuro zo kubungabunga no gusimbuza, bigagabanya ikiguzi cy'imikorere y'igihe kirekire.
Porogaramu z'ingenzi mu nganda
Aya matafari aboneka mu byiciro bitandukanye (48%–80% Al₂O₃), akwiranye n'ibintu bitandukanye bishyuha cyane. Ni meza cyane ku matanura y'ibyuma, amatanura y'ibyuma n'amatanura ashyushya mu nganda z'ibyuma. Anakora nk'urukuta ruramba ku matanura ya sima, amatanura y'indimu, amatanura y'inganda, amatanura y'ibinyabutabire, amatanura y'ibirahure n'amatanura ya ceramic.
Kuki twahitamo
Dutanga amatafari yuzuye ya alumina ifite imiterere isanzwe kandi yihariye, harimo ubwoko bworoheje n'uburemere. Yakozwe muri bauxite ifite ubwiza buhanitse binyuze mu nzira zikomeye zo gusya, ibicuruzwa byacu bifite ubwiza buhamye, ingano nyayo kandi biramba. Dutanga ibisubizo byihariye, ubuyobozi bw'umwuga bwo guhitamo na serivisi yuzuye nyuma yo kugurisha ku bakiriya bo ku isi.
Twandikire kugira ngo ubone inama ku buntu ku byerekeye tekiniki n'igiciro cy'amatafari meza cyane ya alumina!
