Zomera za alumina za polycrystalline Al2O3 zomwe zimateteza kutentha kwambiri

Zomera za alumina za polycrystalline Al2O3 zomwe zimasinthidwa kutentha kwambiri kuti zisawonongeke Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Alumina ceramics (Al203) ndi zinthu zowongoka bwino zomwe sizimawonongeka zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Njira zazikulu zopangira zinthu zowongoka za alumina ceramic ndi kukanikiza kouma, kukanikiza kwa isostatic, kupanga ndi kuponyera jakisoni, ndi zina zotero. Mawonekedwe osiyanasiyana azinthu, kukula ndi kulondola zimafuna njira zosiyanasiyana zopangira. Pambuyo poyatsa zinthu zowongoka za alumina ceramic pa kutentha kwambiri, kugwiritsa ntchito njira yopera diamondi yokha ndi komwe kungakonzedwe. Kuyera kwa zowongoka za alumina wamba ndi 90%-99.9%.

Mawonekedwe

Magwiridwe antchito a aluminiyamu oxide ceramics

1--Kulimba kwambiri

Kulimba kwa alumina ceramics ku Rockwell ndi HRA80-90, yachiwiri yokha kulimba pambuyo pa diamondi, kuposa kulimba kwa chitsulo chosatha komanso kulimba kwa chitsulo chosapanga dzimbiri.

2--Kukana Kuvala Bwino

Kukana kwa alumina ceramics ndi kofanana ndi kukana kwa chitsulo cha manganese nthawi 266 ndi kukana kwa chitsulo cha chromium nthawi 171.5. Pansi pa mikhalidwe yofanana yogwirira ntchito, imatha kukulitsa moyo wa chipangizocho osachepera nthawi khumi.

3--Kulemera Kopepuka

Kuchuluka kwa alumina ceramics ndi 3.7 ~ 3.95g/cm°, komwe ndi theka lokha la chitsulo ndi chitsulo, ndipo kumatha kuchepetsa kwambiri katundu wa zida.

4--Kugwiritsa Ntchito Kosiyanasiyana

Zoumba za alumina zimagwiritsidwa ntchito kwambiri mumakina, fiber optics, zida zodulira, zamankhwala, chakudya, mankhwala, ndege ndi zina.

Ubwino wa alumina ceramics:

1--Zomera za alumina zili ndi mphamvu zabwino kwambiri zotetezera kutentha. Kutayika kwa ma frequency ambiri ndi kochepa, ndipo kutetezedwa kwa ma frequency ambiri ndi kwabwino.

2--Zomera za alumina zimakhala ndi kukana kutentha, kuchuluka kochepa kwa kutentha, mphamvu yayikulu yamakina komanso kuyendetsa bwino kutentha.

3--Zomera za alumina zimakhala ndi kukana mankhwala komanso kukana zitsulo zosungunuka.

4--Zomera za alumina sizimayaka moto, sizimazizira mosavuta komanso zimakhala zolimba komanso sizimawonongeka mosavuta, ndi zinthu zina zachilengedwe komanso zitsulo sizingafanane ndi khalidwe labwino kwambiri.

5--Alumina ceramics ndi yolimba kwambiri, yolimba komanso yofanana, imatha kufika ku Mohs hardness 9, ndipo yolimba kwambiri.
