Ukumelana nokuguguleka okuphezulu okwenziwe ngokwezifiso yi-polycrystalline Al2O3 alumina ceramics

Ukusebenza kwe-aluminium oxide ceramics

1--Ukuqina okuphezulu

Ubulukhuni be-alumina ceramics be-Rockwell buyi-HRA80-90, bulandela idayimane kuphela ngobulukhuni, budlula kakhulu insimbi engagugi kanye nokumelana nokuguguleka kwensimbi engagqwali.

2--Ukumelana Okuhle Kokugqokwa

Ukumelana nokuguguleka kwe-alumina ceramics kufana nokuguguleka kwensimbi ye-manganese izikhathi ezingu-266 kanye nensimbi ye-chromium eningi izikhathi ezingu-171.5. Ngaphansi kwezimo ezifanayo zokusebenza, kungandisa impilo yesevisi yemishini okungenani izikhathi eziyishumi.

3--Isisindo Esilula

Ubuningi be-alumina ceramics bungu-3.7 ~ 3.95g/cm°, okuyingxenye nje yensimbi nensimbi, futhi kunganciphisa kakhulu umthwalo wemishini.

4--Ububanzi Bokusetshenziswa

I-Alumina ceramics isetshenziswa kabanzi emishinini, kuma-fiber optics, kumathuluzi okusika, kwezokwelapha, ekudleni, kumakhemikhali, ezindiza kanye nakweminye imikhakha.

Izinzuzo ze-alumina ceramics:

1--I-Alumina ceramics inezakhiwo ezinhle kakhulu zokuvikela umswakama. Ukulahleka kwemvamisa ephezulu kuncane kakhulu, futhi ukuvikela kwemvamisa ephezulu kuhle.

2--I-Alumina ceramics inokumelana nokushisa, i-coefficient encane yokwanda kokushisa, amandla aphezulu omshini kanye nokuqhuba kahle kokushisa.

3--Izitsha zobumba ze-Alumina zinokumelana namakhemikhali kanye nokumelana nensimbi encibilikisiwe.

4--Izitsha zobumba ze-alumina azishisi, azigqwali kalula futhi ziqinile futhi azilimazi kalula, nezinye izinto eziphilayo kanye nezinto zensimbi azinakuqhathaniswa nekhwalithi enhle kakhulu.

5--I-Alumina ceramics ukumelana nokuguguleka okuphezulu, ubulukhuni kanye ne-corundum okufanayo, ingafinyelela ubulukhuni be-Mohs 9, ukumelana kwayo nokuguguleka kungalinganiswa nama-alloys aqinile kakhulu.
