Imipira irwanya alumina ifite ubuziranenge bwiza bw'imbaraga nyinshi, ubukana bwinshi, ubushobozi bwo gushwanyagurika neza, ubucucike bwinshi, ubushobozi bwo gushwanyagurika buri hejuru, ubushobozi bwo kurwanya ingese, umwanda muke n'indi miterere myiza. Imipira ya alumina yakoreshejwe cyane mu kurangiza no gutunganya mu buryo bwimbitse ubwoko butandukanye bwa ceramic, enamel, ikirahure, imiti n'ibindi bikoresho bikomeye kandi bikomeye.
Imiterere y'imipira ya alumina ihindura imiterere y'umubiri
- Ubudahangarwa bw'ubushyuhe bwinshi
- Ubudahangarwa bwiza bw'ubushyuhe
- Imbaraga nyinshi za mekanike
- Igihe kirekire cyo gukora
Imiterere y'imipira ya Alumina Refractory
Udupira twa alumina dukozwe muri AL2O3, kaolin, synthetic aggregate, mullite crystal n'ibindi bikoresho. Dukurikije uburyo bwo gukurura no gukanda, udupira twa aluminiyumu dukomeye dufite akamaro ko gukomera cyane, kudashyuha neza, gusimbuza no gusukura byoroshye, kumara igihe kirekire n'ibindi.
Uburyo bwo gukoresha imipira ya alumina
Kugira ngo hakorwe imipira irwanya alumina, electrode ishyirwa hasi ku gice cyo hejuru cya grafiti, kandi arc ishobora gutangizwa wongeyeho ingano runaka y'ifu ya alumina ikoreshwa mu nganda. Umuvuduko ukoresha 1.0kA, voltage 80 ~ 100V. Nyuma yo gukubita, uko Al2O3 ishonga, ikagenda yiyongera buhoro buhoro, kugeza igihe amazi y'ibikoresho yujujwemo icyuma cyo hejuru cya grafiti, ubushyuhe bw'amazi y'ibikoresho ni 2200 ~ 2300 ℃. Nyuma y'ibyo, icyuma cyo hejuru kirasukwa maze umuti ugasohoka.

Gukoresha imipira ya alumina ihindura imiterere y'umubiri
Imipira irwanya alumina yakoreshejwe cyane mu kurangiza no gutunganya mu buryo bwimbitse ubwoko butandukanye bwa ceramic, enamel, ikirahure, imiti n'ibindi bikoresho bikomeye kandi bikomeye. Cyane cyane imipira irwanya aluminiyumu ikwiriye ibikoresho byo gutandukanya umwuka n'itanura rishyushya gaze nk'ibikoresho byo kubika ubushyuhe.
