Itandukaniro hagati yubutaka bwa alumina nubutaka buboneye

Igitekerezo gitandukanye

Alumina ceramic ni ubwoko bwibikoresho bya ceramic hamwe na alumina (AI203) nkumubiri nyamukuru.

Ubukorikori bubonerana buboneka hakoreshejwe ibikoresho byiza bya ultra-nziza ceramic ibikoresho fatizo no gukuraho imyenge hakoreshejwe ikoranabuhanga.

Ibigize hamwe nibyiciro biratandukanye

Ububiko bwa Alumina bugabanijemo ubwoko bwera nubwoko busanzwe bwa kabiri.

Ubukorikori bwinshi bwa alumina ceramics nibikoresho byubutaka birimo AI203 biri hejuru ya 99.9% .Bitewe nubushyuhe bwacyo bugera kuri 1650-1990℃no gukwirakwiza umurongo wa 1 ~ 6um, mubusanzwe bikozwe mubirahure bishongeshejwe kugirango bifate igisekuru cya platine gikomeye;Koresha itara ryayo hamwe na alkali ibyuma birwanya ruswa nka sodium itara;Irashobora gukoreshwa nkibibaho byumuzunguruko hamwe nibikoresho byinshi byokwirinda mubikorwa bya elegitoroniki.

Ubukorikori busanzwe bwa alumina bugabanijemo ibice 99, farisari 95, farashi 90, farisari 85 nandi moko ukurikije ibikubiye muri A1203, kandi rimwe na rimwe ibirimo A1203 nabyo bishyirwa mubikorwa bisanzwe bya alumina ceramics.Ibikoresho 99 bya alumina ceramic bikoreshwa mugukora ubushyuhe bwo hejuru cyane, umuyoboro witanura wangiritse hamwe nibikoresho bidasanzwe birwanya kwambara, nkibikoresho bya ceramic, kashe ya ceramic na valves yamazi;95 alumina farforine ikoreshwa cyane cyane mukurwanya ruswa no kwambara ibice byo kurwanya;Isafuriya 85 ikunze kuvangwa na talc kugirango itezimbere amashanyarazi nimbaraga za mashini, kandi irashobora gufungwa na molybdenum, niobium, tantalum nibindi byuma, kandi bimwe bikoreshwa nkibikoresho bya vacuum.

Ubukorikori buboneye bushobora kugabanywamo ibice bya aluminium oxyde, ceramics yttrium oxyde, ceramics ya magnesium oxyde, ceramics yttrium aluminium garnet, ceramics ya aluminium magnesium, ceramics ya aluminium nitride, aluminium nitride, ububumbyi buboneye nibindi.

Imikorere itandukanye

Ibikoresho bya Alumina ceramic:

1. Ubukomere bukabije bugenwa n’ikigo cya Shanghai Institute of Silicate of the Academy of Science of China, ubukana bwacyo bwa Rockwell ni HRA80-90, ubukana ni ubwa kabiri nyuma ya diyama, burenze kure kwihanganira kwambara ibyuma bidashobora kwangirika ndetse nicyuma kitagira umwanda.

2. Kurwanya kwambara neza Byapimwe na Powder Metallurgy Institute of Central Central University, kwihanganira kwambara bihwanye ninshuro 266 zicyuma cya manganese ninshuro 171.5 zicyuma kinini cya chromium.Dukurikije ubushakashatsi bwakozwe nabakiriya bacu mumyaka irenga icumi, mubihe bimwe byakazi, ubuzima bwa serivisi bwibikoresho bushobora kongerwa byibuze inshuro icumi.

3. Uburemere bworoheje Ubucucike bwacyo ni 3.5g / cm3, ni kimwe cya kabiri cyibyuma, bishobora kugabanya cyane imitwaro yibikoresho.

Ibikoresho bya ceramic bisobanutse:

Ubukorikori buboneye nkishami ryububumbyi bwateye imbere, usibye kuragwa ubushyuhe bwo hejuru bwubushyuhe bwo hejuru, kurwanya ruswa, imbaraga nyinshi, ubukana bwinshi, ituze ryimiti, coefficente yo kwaguka byiyongereyeho, itangwa ryumucyo udasanzwe bituma ryongera mubikorwa byinshi.

Porogaramu zitandukanye

Ububiko bwa Alumina bukoreshwa cyane mu mashini, fibre optique, ibikoresho byo gukata, ubuvuzi, ibiryo, imiti, ikirere ndetse n’inganda.

Ubukorikori bubonerana bukoreshwa cyane cyane mu gucana amatara, ibikoresho bya laser, ibikoresho byo mu idirishya rya infragre, flicker ceramics, ceramics electro-optique, ibikoresho bitagira amasasu.
