Icyegeranyo cy'ikoreshwa ry'ibibumbano bya alumina bidashira

Ubudahangarwa bw'ibinyabutabire bya alumina buturuka ku miterere yabyo yihariye y'umubiri n'imiti: Ubukana bwa Mohs bwa alumina ceramics ni 9, bugakurikira diyama gusa. Mu buryo bwa mikorosikopi, imiterere ya kristu ikomeye igizwe n'imigozi ikomeye ya iyoni ishobora kurwanya byimazeyo kwibasira uduce twa ioni. Ubushakashatsi bwerekana ko kudahangarwa kwayo gushobora kugera ku nshuro 266 z'icyuma cya manganese n'inshuro 171.5 z'icyuma cya chromium cast cast. Byongeye kandi, ibinyabutabire bya alumina bifite ubushobozi bwo kudahangarwa n'ubushyuhe. Bishobora kugumana ubuziranenge bw'imiterere mu bidukikije birimo aside, alkaline n'ubushyuhe bwinshi kandi bishobora gukoreshwa mu bihe bikomeye by'akazi.

Ingero z'ikoreshwa ryaibumba rya alumina ridashobora kwangirika:
1. Ibice bidashobora kwangirika ku bikoresho bya mekanike:sisitemu zo gutwara ibintu (nk'imashini zitwara ibintu ku giti cyazo, imiyoboro itwara ibintu ikoresheje umwuka, nibindi), pompe na valve seal, mixer blades, bearing, ceramic cutting tools, nibindi. Bishobora gusimbura ibikoresho gakondo by'icyuma no kugabanya igihe cyo kudakora ibikoresho byo kubungabunga giterwa no kwangirika no kwangirika.
2. Inganda z'ubucukuzi bw'amabuye y'agaciro n'ibyuma:Ikoreshwa mu byuma bisya amabuye y'agaciro, ibikoresho bitunganya amabuye y'agaciro (nk'ibice by'imbere by'inkubi z'umuyaga), ibikoresho byo gusya ibyuma bisya umupira, ibice by'imbere by'amatanura ashyushye cyane, n'ibindi. Irwanya ingaruka n'ingufu z'amabuye n'ibisigazwa, kandi yongerera igihe cyo gukora ibikoresho.
3. Gutwara bateri ya Lithium:Imiyoboro ya alumina ikoreshwa mu miyoboro itwara batiri ya lithium, ibyo bikaba bidatuma imiyoboro iramba gusa ahubwo binarinda umwanda no kuzigama ikiguzi cyo gusimbuza imiyoboro.
4. Inganda z'ibikoresho by'ikoranabuhanga n'ibikoresho bya semiconductor:Ibibaho by’amashanyarazi bihujwe, ibikoresho byo gupfunyikamo hakoreshejwe ikoranabuhanga, ibice bikingira umuriro mwinshi, ibice birwanya kwangirika mu bikoresho bitunganya wafer (nk'amaboko ya roboti, ibikoresho), ibyumba birwanya ingese.
5. Inganda zikora imiti n'ibikomoka kuri peteroli:Imiyoboro y'imbere y'imiyoboro y'ibinyabutabire, ipompo za shimi na vali, imiyoboro, ibice bya centrifuge, impeta zidashira zo gucukura. Imiyoboro y'ibinyabutabire n'imiyoboro y'imbere y'imiyoboro ya peteroli.

Kuba alumina ceramics idashira cyane ni ubushobozi bwayo bwo guhangana mu nganda. Kandi binyuze mu guhuza ibikoresho, guhanga udushya mu mikorere no kwagura ikoreshwa, ubushobozi bwayo buracyakomeza gusohoka. Mu gihe kizaza, inganda zigomba kongera imbaraga z'ibikoresho no kugabanya ibiciro mu gihe zibanda ku byifuzo by'isoko ryo ku rwego rwo hejuru, guteza imbere impinduka kuva ku "bwinshi" kugera ku "bwiza", no gutanga ibisubizo byiza ku nzego zikiri kuzamuka nko gukora ibikoresho by'ubwenge n'ingufu zirengera ibidukikije.
