Kodi magwiridwe antchito a alumina ceramics ndi chiyani?

Alumina ceramics ndi mtundu wa Al2O3 monga zopangira zazikulu, corundum (α-al2o3) monga gawo lalikulu la crystalline la zinthu zadothi, pakalipano dziko lalikulu kwambiri la zida za oxide ceramic.Ndipo chifukwa alumina ceramic ndi chinthu chosamva bwino kwambiri cha ceramic, chimagwiritsidwa ntchito kwambiri m'mbali zonse za moyo.

Zoumba za aluminiyamu zili ndi mawonekedwe awa:

1. Valani kukana

Ma aluminiyamu oyeretsedwa kwambiri amakhala ndi kukana kwabwino kwambiri, komwe kuli koyenera magawo omwe amagwiritsidwa ntchito kwa nthawi yayitali.

2, palibe deformation

Ma aluminiyamu oyeretsedwa kwambiri ndi zida zabwino kwambiri zamagawo olondola chifukwa ali ndi mphamvu zopindika zolimba komanso mphamvu zopondereza ndipo sizosavuta kuwononga.

3, yosavuta kuyeretsa

Pamwamba pa alumina ceramics ndi yosalala, sikophweka kumamatira ku zonyansa, ndipo ndi kosavuta kuyeretsa.Choncho, ndi yoyenera kugwiritsidwanso ntchito komanso kufunika kokhala aukhondo pazachipatala.

4, kukana mankhwala

Zoumba za aluminiyamu zimakhala ndi asidi amphamvu komanso alkali kukana kuwonongeka kwa mankhwala, ndipo palibe chifukwa chodera nkhawa za momwe mankhwala amagwiritsidwira ntchito ndi mankhwala ena.

5, kutchinjiriza bwino

High purity alumina ceramic ndi chinthu chabwino kwambiri chotchingira chifukwa chocheperako, imatha kupirira voteji ngati insulating, kutsika kwamphamvu, ngakhale kutentha kwambiri kusungitsa kutentha, komanso kukana kutentha kwambiri.

6, kukana kwa plasma

Chifukwa cha chiyero chachikulu cha alumina ceramics (Al 2 O 3> 99.9%) ndipo alibe tsankho pafupifupi intergranular ndipo, chifukwa chake, amagwiritsidwa ntchito ngati zinthu zotsutsana ndi plasma.

Mwachidule, pali zina mwazochita za alumina ceramics.Alumina ceramics ali ndi udindo wapamwamba pazambiri za ceramic, ndipo amagwiritsidwa ntchito kwambiri pamagetsi, zida zamagetsi, makina, nsalu, zakuthambo ndi zina.
