I-Polycrystalline Al2O3 alumina ceramics eyenziwe ngokwezifiso ukumelana nokushisa okuphezulu

Incazelo emfushane:

I-Alumina Ceramics (Al203) iyisisetshenziswa sobumba esinembayo esingagugi esisetshenziswa kakhulu ezimbonini ezahlukahlukene. Izindlela eziyinhloko zokubumba zemikhiqizo ye-alumina ceramic ukucindezela okomile, ukucindezela kwe-isostatic, ukubunjwa komjovo nokubunjwa, njll. Ukwakheka kwemikhiqizo ehlukene, ubukhulu kanye nokunemba kudinga izindlela zokubumba ezihlukene. Ngemuva kokushisa okuphezulu kwe-sintering yemikhiqizo ye-alumina ceramic, kuphela ukusetshenziswa kwenqubo yokugaya idayimane kungacutshungulwa. Ukuhlanzeka kwe-alumina ceramics evamile yi-90% -99.9%.

Ukusebenza kwe-aluminium oxide ceramics

1--Ukuqina okuphezulu

Ubulukhuni be-Rockwell be-alumina ceramics yi-HRA80-90, isibili ngemva kwedayimane ngobulukhuni, bungaphezulu kakhulu kunensimbi engagugi kanye nokumelana nokugqokwa kwensimbi engagqwali.

2--Ukumelana Okuhle Kwe-Wear

Ukumelana nokugqokwa kwezitsha zobumba ze-alumina kulingana nezikhathi ezingama-266 zensimbi ye-manganese kanye nezikhathi eziyi-171.5 zensimbi ephezulu ye-chromium. Ngaphansi kwezimo ezifanayo zokusebenza, inganweba impilo yesevisi yemishini okungenani izikhathi eziyishumi.

3--Isisindo Esilula

Ukuminyana kwezitsha zobumba ze-alumina kungu-3.7~3.95g/cm°, okuyingxenye kuphela yaleyo yensimbi nensimbi, futhi kunganciphisa kakhulu umthwalo wemishini.

4--Uhla Olubanzi Lokusebenza

I-Alumina Ceramics isetshenziswa kabanzi emishinini, kwi-fiber optics, amathuluzi okusika, ezokwelapha, ezokudla, amakhemikhali, e-aerospace kanye neminye imikhakha.

Izinzuzo ze-alumina ceramics:

1--Izitsha zobumba ze-alumina zinezakhiwo ezinhle kakhulu zokuvikela. Ukulahleka kwe-high-frequency kuncane uma kuqhathaniswa, futhi ukufakwa kwe-high-frequency kuhle.

I-2-- I-ceramics ye-alumina inokumelana nokushisa, i-coefficient encane yokwanda kwe-thermal, amandla aphezulu emishini kanye nokuhamba kahle kwe-thermal.

3-- I-Alumina ceramics inokumelana namakhemikhali nokumelana nensimbi encibilikisiwe.

I-4-- I-ceramics ye-Alumina ayivuthi, akulula ukugqwala futhi iqinile futhi akulula ukuyilimaza, nezinye izinto eziphilayo kanye nezinto zensimbi azikwazi ukuqhathaniswa nekhwalithi enhle kakhulu.

I-5--Alumina Ceramics ukumelana nokugqoka okuphezulu, ubulukhuni kanye ne-corundum efanayo, ingafinyelela ubulukhuni be-Mohs 9, ukumelana kwayo nokugqoka kungafaniswa nama-alloys aqinile kakhulu.
