Ke komo nei i ke ao ʻoihana hou, hiki i kekahi ke ʻike mau i ke alo o kahi ʻano mea kūikawā - ʻaʻole lākou e ʻālohilohi e like me nā metala a ʻaʻole hoʻi e like me ka māmā e like me nā plastics, akā kākoʻo mālie lākou i ka hana o ka ʻoihana hou. ʻO kēia ka ʻohana keramika ʻoihana, kahi hui o nā mea inorganic non-metallic i kaulana no ko lākou mau waiwai kūikawā.
I. ʻO nā "lālā hōkū" o ka ʻohana keramika ʻoihana
Ma waena o ka ʻohana keramika ʻoihana, aia kekahi mau lālā i kū i waho: ʻO nā keramika Alumina e like me ke kaikuaʻana hilinaʻi, e hilinaʻi ana i ka insulation maikaʻi loa a me ke kūpaʻa i ka corrosion, e pāʻani ana i kahi kuleana koʻikoʻi i nā ʻāpana uila a me nā lako kemika; ʻO nā keramika Silicon nitride e like me nā mea pāʻani māmā, nona ka paʻakikī o nā keramika a me ka paʻakikī o nā metala, e hōʻike ana i ka hana maikaʻi loa i nā bearings a me nā mea ʻokiʻoki; ʻO nā keramika Zirconia e like me nā fashionistas, ʻaʻole wale ka loaʻa ʻana o ka luster e like me ka momi akā loaʻa pū kekahi ʻenehana ʻeleʻele o ka "phase transformation toughening", makemake nui ʻia i nā dentures a me nā ʻāpana pololei.
II.Nā keramika carbide silikonaʻO ke koa holoʻokoʻa ma ke kahua ʻoihana
Ma waena o kēia ʻohana, hiki ke manaʻo ʻia nā keramika silicon carbide ʻo ia ke koa maoli a puni. Ua hana mua ʻia kēia keramika kūikawā i haku ʻia me nā mea silicon a me ke kalapona e nā kānaka i ka makahiki 1905 a ua uhaʻi mau i nā moʻolelo hana o nā mea ʻoihana. Ua like ia me ka pale i hana ʻia me ka daimana, me ka paʻakikī Mohs a hiki i ka 9.5, ʻo ka lua wale nō ia o ke daimana ponoʻī; ua like ia me ke kapa kila i hoʻoheheʻe ʻia mai nā piliki refractory, hiki ke kū i ka 1350℃ o ka hoʻomoʻa wela kiʻekiʻe.
Ma ka hale hana metallurgical, kākoʻo nā keramika silicon carbide i hana ʻia i nā kilnware i ka hoʻopau ʻana i nā bila kila; i loko o nā pipeline kemika, hoʻololi ia i mea pale kū i ka pala, e hoʻolōʻihi ana i ke ola lawelawe o nā pipelines; ma nā laina hana semiconductor, he koho kūpono hoʻi ia no ka bearing pololei; ʻoi aku ka mea kupanaha, ʻo kēia mea kaumaha he mea alakaʻi wela maikaʻi loa ia, e loaʻa ai kona wahi ma ke kahua o ka hoʻoheheʻe wela uila.
III. Ka hoʻololi ʻana a me ka hānau hou ʻana i lawe ʻia mai e ka ʻenehana
Ua hāʻawi ka ʻenehana hou i nā keramika silicon carbide me ke ola hou. Ma o ka ʻenehana nanomodification, ua hoʻonui nā kānaka ʻepekema i kona paʻa; me ka hoʻohana ʻana i ka ʻenehana paʻi 3D, hiki ke hana ʻia nā ʻāpana ʻano paʻakikī e like me nā hana noʻeau. Ma ke keʻena hoʻokolohua o kā mākou hui, ke aʻo nei nā ʻenekinia i nā ʻano sintering silicon carbide, me ka hoʻohana ʻana i ka ʻenehana sintering holomua e hoʻokō i nā koi huahana like ʻole o nā mea kūʻai aku a hoʻomaikaʻi mau i ka hana o nā huahana keramika silicon carbide, e hiki ai iā lākou ke hoʻololi i nā kūlana hana paʻakikī.
Mai ka ʻoihana kuʻuna a i ka ʻenehana ʻoi loa, ke kākau nei nā keramika ʻoihana i kahi moʻolelo hou. Ma ke ʻano he mea lawelawe ʻenehana loea i nā keramika silicon carbide, ua kūpaʻa mau mākou i ka hāʻawi ʻana i nā hoʻonā i hana ʻia. Inā paha he hana ʻana o nā ʻāpana ʻano kūikawā me nā kikoʻī kūikawā a i ʻole ka hoʻolālā ʻana o nā hoʻonā noi no nā kūlana hana koʻikoʻi, hiki iā mākou ke loaʻa ke kākoʻo ʻoihana ma aneʻi.
