Zinthu Zofunika Kwambiri Zokhudza Kukhazikika kwa Zida Zolimba Zosavala

Alumina ceramics ndi mtundu wa zipangizo za ceramic zomwe alumina ndiye thupi lalikulu. Alumina ceramics ali ndi conductivity yabwino, mphamvu yamakina, kukana kuvala komanso kukana kutentha kwambiri, komwe kumadziwikanso kuti ceramics yapadera. Al2O3 ceramic structure ndi hexagonal structure yolimba yokhala ndi oxygen ion, ndi aluminiyamu ion yodzazidwa ndi magawo awiri mwa atatu a octahedral gap, yomwe ndi yofanana ndi kapangidwe kachilengedwe ka corundum stable α-Al2O3, kotero ceramic ili ndi malo osungunuka kwambiri, kuuma kwakukulu, komanso kukana kuvala bwino. Alumina ceramic hardness ≥HRA85, kuuma ndi kwachiwiri kwa diamondi, kukana kwake kuvala ndi kwabwino kwambiri.

Kawirikawiri, alumina ceramic aluminiyamu imagawidwa m'magulu awiri: mtundu wamba ndi mtundu woyera kwambiri. Malinga ndi kuchuluka kwa Al2O3, mtundu wamba umagawidwa m'magulu awiri: 92% alumina ceramic, 95% alumina ceramic, 96% alumina ceramic. Mtundu woyera kwambiri ndi 99% alumina ceramic ndipo pamwamba pa ceramic, kutentha kwake kotentha kumafika pa 1650-1990℃. 99.7%-99.9% alumina ceramics ingagwiritsidwe ntchito mumakampani amagetsi monga bolodi lozungulira lophatikizidwa ndi zida zotenthetsera pafupipafupi, semiconductor makampani mu ma wafers a silicon opukutira, ndi zina zotero, ndi safiro ndi semiconductor silicon wafer mankhwala opukutira makina ochiritsira zigawo ndi zinthu zina zogwiritsidwa ntchito.

Zitsulo za alumina zikachuluka kwambiri, ntchito yake imakhala yokhazikika, ndiko kuti, aluminiyamu ikachuluka, ntchito yake imakhala yolimba kwambiri. Zitsulo za alumina monga zipangizo zamakono za ceramic, zomwe zikukula mwachangu kuchokera ku zipangizo zatsopano zosagwirizana ndi kuwonongeka kwa mafakitale, zidzagwiritsidwa ntchito kwambiri m'madera amakono.

Chemshun Ceramics imapereka ma ceramics osiyanasiyana oyera kwambiri a alumina, monga: 92% Al2O3 ndi 95% Al2O3 alumina ceramic liner yokhazikika yosavala, zidutswa za ceramic lining ndi mphasa, matailosi a hexagon/square ceramic, ceramic pipe/tube/elbow, ceramic silinda, ceramic block/cube, ceramic njerwa, 99.7% alumina baseboard ndi alumina wafer polishing plate, 99% alumina bulletproof ceramic, ndi zina zotero.
