ʻO ke kūpaʻa o ka ʻaʻahu o nā keramika alumina mai ko lākou mau waiwai kino a me ke kemika kū hoʻokahi: ʻO ka paʻakikī Mohs o nā keramika alumina he 9, ʻo ka lua wale nō i ka daimana. Ma ke ʻano microscopic, hiki i ke ʻano kristal mānoanoa i haku ʻia me nā pilina ionic ikaika ke pale pono i ka hoʻouka kaua ʻana o nā ʻāpana ʻaʻahu. Hōʻike nā haʻawina hiki i kona kūpaʻa ʻaʻahu ke hiki i 266 mau manawa o ke kila manganese a me 171.5 mau manawa o ka hao i hoʻolei ʻia me ka chromium kiʻekiʻe. Eia kekahi, loaʻa i nā keramika alumina ke kūpaʻa kemika a me ka wela. Hiki iā lākou ke mālama i ka pono o ke kūkulu ʻana i nā wahi waikawa, alkaline a me nā wahi wela kiʻekiʻe a hiki ke hoʻohana ʻia i nā kūlana hana koʻikoʻi.
Nā hiʻohiʻona noi onā keramika alumina kūpaʻa ʻaʻahu:
1. Nā ʻāpana pale no nā lako mīkini:nā ʻōnaehana lawe (e like me nā mea lawe wili, nā paipu lawe pneumatic, a pēlā aku), nā sila pamu a me nā valve, nā pahi kāwili, nā bearings, nā mea ʻoki keramika, a pēlā aku. Hiki iā ia ke pani i nā mea metala kuʻuna a hōʻemi i ka downtime o nā lako no ka mālama ʻana i hoʻokumu ʻia e ka ʻaʻahu a me ka waimaka.
2. ʻOihana hana mining a me metallurgical:Hoʻohana ʻia ia i nā mea wili, nā lako hana mineral (e like me nā uhi o loko o nā cyclones), nā mea wili no nā wili pōpō, nā uhi o loko o nā umu wela kiʻekiʻe, a pēlā aku. E kūʻē i ka hopena a me ke komo ʻana o nā ores a me ka slag, a hoʻolōʻihi i ke ola lawelawe o nā lako.
3. Ka halihali ʻana i ka pila Lithium:Hoʻohana ʻia nā paipu keramika alumina i nā paipu halihali pākahiko lithium, ʻaʻole wale ia e hōʻoia i ke kūpaʻa o nā pipelines akā pale pū i ka haumia a mālama i ke kumukūʻai o ka hoʻololi pipeline.
4. ʻOihana uila a me semiconductor:Nā papa kaapuni i hoʻohui ʻia, nā mea hoʻopili uila, nā ʻāpana hoʻokaʻawale uila kiʻekiʻe, nā ʻāpana kūpaʻa i ke komo ʻana i nā lako hana wafer (e like me nā lima robotic, nā mea paʻa), nā keʻena hopena kūpaʻa i ka corrosion.
5. Nā ʻoihana kemika a me ka ʻaila:Nā uhi o loko o nā ipu hana, nā pamu kemika a me nā kiwikā, nā paipu, nā ʻāpana centrifuge, nā apo pale ʻaʻahu no nā lako wili. Nā bushings pamu lepo a me nā uhi o loko o nā paipu aila.
ʻO ke kūpaʻa kiʻekiʻe o ka ʻaʻahu o nā keramika alumina kona hoʻokūkū koʻikoʻi ma ke kahua ʻoihana. A ma o ka hoʻohuihui ʻana i nā mea, ka hana hou ʻana o ke kaʻina hana a me ka hoʻonui ʻana i ka noi, ke hoʻokuʻu mau ʻia nei kona hiki. I ka wā e hiki mai ana, pono ka ʻoihana e hoʻonui i ka paʻakikī o nā mea a hoʻemi i nā kumukūʻai me ka hoʻolālā ʻana i nā koi o ka mākeke kiʻekiʻe, e paipai ana i ka hoʻololi ʻana mai ka "nui" a i ka "maikaʻi", a me ka hāʻawi ʻana i nā hopena maikaʻi aʻe no nā kahua e kū mai ana e like me ka hana akamai a me ka ikehu ʻōmaʻomaʻo.
