Kodi magwiridwe antchito a alumina ceramics ndi chiyani?

Zojambula za aluminiyamundi mtundu wa Al2O3 monga zopangira zazikulu, corundum (α-al2o3) monga gawo lalikulu la crystalline la zinthu za ceramic, pakalipano dziko lalikulu kwambiri la oxide ceramic zipangizo. Ndipo chifukwaaluminiyamu ceramicndi chinthu chosamva bwino kwambiri cha ceramic, chomwe chimagwiritsidwa ntchito kwambiri m'mbali zonse za moyo.

Zojambula za aluminiyamuali ndi machitidwe awa:

1. Valani kukana

Chiyero chachikulualuminiyamu ceramicskukhala ndi kukana kwabwino kwambiri kovala, komwe kuli koyenera magawo omwe amagwiritsidwa ntchito kwa nthawi yayitali.

2, palibe deformation

Chiyero chachikulualuminiyamu ceramicsndi zida zabwino kwambiri zamagawo olondola chifukwa ali ndi mphamvu yopindika mwamphamvu komanso mphamvu yopondereza ndipo sizosavuta kuwononga.

3, yosavuta kuyeretsa

Pamwamba paaluminiyamu ceramicsndi yosalala, si yapafupi kumamatira ku zonyansa, ndi yosavuta kuyeretsa. Choncho, ndi yoyenera kugwiritsidwanso ntchito komanso kufunika kokhala ndi ukhondo pazachipatala.

4, kukana mankhwala

Zojambula za aluminiyamukukhala ndi asidi amphamvu ndi alkali kukana dzimbiri za mankhwala, ndipo palibe chifukwa chodandaula ndi zochita za mankhwala ndi mankhwala ena pakugwiritsa ntchito.

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 kutsekereza, 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.
