Polycrystalline Al2O3 alumina ceramics yakagadzirirwa yakakwirira tembiricha kupfeka kuramba

Tsanangudzo Pfupi:

Alumina ceramics (Al203) inopfeka-inodzivirira chaiyo ceramic zvinhu iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana. Nzira huru dzekuumba dzealumina ceramic zvigadzirwa dzakaoma kudzvanya, isostatic kudzvanya, jekiseni kuumba uye kukanda, etc. Zvimiro zvakasiyana zvechigadzirwa, saizi uye nemazvo zvinoda nzira dzakasiyana dzekuumba. Mushure mekupisa-kupisa kwekupisa kwealumina ceramic zvigadzirwa, chete kushandiswa kwedhaimani kugaya nzira kunogona kugadziriswa. Kuchena kweakajairwa alumina ceramics ndeye 90% -99.9%.

Aluminium oxide ceramics kuita

1--Kuoma kwakakwirira

Rockwell kuomarara kwealuminium ceramics iHRA80-90, yechipiri chete kune dhaimondi mukuomarara, zvakanyanya kupfuura kupfeka-inodzivirira simbi uye simbi isina tsvina yekupfeka kuramba.

2--Zvakanaka Wear Resistance

Kupfeka kupikisa kwealuminium ceramics kwakaenzana ne266 nguva dzesimbi yemanganese uye 171.5 nguva dzepamusoro chromium cast iron. Pasi pemamiriro akafanana ekushanda, inogona kuwedzera hupenyu hwebasa remidziyo kanenge kagumi.

3--Kureruka Kurema

Kuwanda kwealuminium ceramics ndeye 3.7 ~ 3.95g / cm °, iyo inongova hafu yesimbi nesimbi, uye inogona kuderedza zvakanyanya mutoro wemidziyo.

4--Wide Range yekushandisa

Alumina ceramics anoshandiswa zvakanyanya mumichina, faibha optics, kucheka maturusi, kurapwa, chikafu, makemikari, aerospace uye mamwe minda.

Zvakanakira zvealuminium ceramics:

1--Alumina ceramics ine yakanakisa insulating zvivakwa. High-frequency kurasikirwa idiki, uye yakakwirira-frequency insulation yakanaka.

2--Alumina ceramics ine kupisa kwekudzivirira, diki coefficient yekuwedzera kwekupisa, yakakwira mechanical simba uye yakanaka yekupisa conductivity.

3--Alumina ceramics ine makemikari kuramba uye yakanyungudutswa simbi kuramba.

4--Alumina ceramics haibatike, haisi nyore kuita ngura uye yakasimba uye haisi nyore kukuvadza, nezvimwe zvinhu zvehupenyu uye zvigadzirwa zvesimbi hazvigoni kuenzaniswa nehutano hwakanaka.

5--Alumina ceramics yepamusoro kupfeka kuramba, kuomarara uye corundum zvakafanana, inogona kusvika kuMohs kuomarara 9, kupfeka kwayo kuramba kunogona kuenderana neakanyanya-akaoma alloys.
