ipu hoʻoheheʻe keramika silikona

I nā ʻoihana e like me ka metallurgy, ka ʻenekinia kemika, a me ka ikehu hou, aia kahi ipu i manaʻo ʻia he mea ʻole akā koʻikoʻi - ka ipu hoʻoheheʻe. Inā like nā ipu hoʻoheheʻe kuʻuna me nā "kīʻaha laiki hao", a lailanā ipu hoʻoheheʻe keramika silicon carbidehe mau mana i hoʻonui ʻia o nā "uhi pale titanium alloy". Ma ke ʻano he "hero ma hope o nā hiʻohiʻona" o ka ʻoihana hou, ke wehewehe hou nei kēia pahu aniani ʻeleʻele i nā kūlana palekana no nā hana wela kiʻekiʻe.
Ke Wehewehe ʻana i ka 'ʻenehana ʻeleʻele': Ka Hāʻawi Kūlohelohe o Silicon Carbide
ʻO Silicon carbide (SiC), ma ke ʻano he ʻāpana koʻikoʻi o nā mea semiconductor hanauna ʻekolu, hōʻike pū kekahi i ka hiki kupaianaha i ke kahua o nā keramika. Loaʻa i kēia kristal superhard i hana ʻia me kahi ʻano atomika e like me kahi lattice daimana i kūkulu pono ʻia, e hāʻawi ana i ka mea me ʻekolu mau pono kūlohelohe: ke kūʻē ʻana i nā mahana kiʻekiʻe ma luna o 1350 ℃ me ka ʻole o ka hoʻololi ʻana i ke kala, ka maʻalahi i ke kūʻē ʻana i nā mea corrosive, a me ka hoʻoili wela e like me nā alakaʻi metala. ʻO kēia pale ʻekolu-dimensional o "ke kūʻē wela + ke kūʻē ʻana i ka corrosion + ke alakaʻi wela" e waiho ana i nā ipu hao metala maʻamau a i ʻole graphite ma hope loa.

Mana Paʻakikī Kūlohelohe: Nā Mea Haʻihaʻi i nā Hiʻohiʻona ʻOihana
Ma lalo o nā kūlana hana koʻikoʻi, hōʻike nā ipu hoʻoheheʻe keramika silicon carbide i ke kūpaʻa kupaianaha. Ma ka hale hana metallurgical, hiki iā ia ke lawelawe maʻalahi i ka erosion wela kiʻekiʻe; I nā hopena kemika, noho mau ia me ka neʻe ʻole i nā wahi ʻino loa; Ma ka hale hana ikehu hou, ʻo kona conductivity thermal like e hōʻoiaʻiʻo ana i ka pololei o ka synthesis mea. ʻO ka mea ʻoi aku ka kakaikahi, hiki ke hoʻohana hou ʻia kēia 'kino daimana hiki ʻole ke luku ʻia', e hoʻemi nui ana i ke alapine o ka hoʻololi ʻana i nā lako.
Koho Akamai: Waiwai Lōʻihi i ʻIke ʻia
ʻO ke koho ʻana i kahi ipu hoʻoheheʻe keramika silicon carbide, ʻo ia ke koho ʻana i kahi naʻauao ʻoihana. ʻOiai ʻoi aku ka kiʻekiʻe o ka hoʻopukapuka mua ʻana i hoʻohālikelike ʻia me nā mea kuʻuna, hiki i kāna hana lōʻihi a paʻa hoʻi ke pale aku i nā kumukūʻai huna e like me ka hoʻopau ʻana i ka hana a me ka haumia o nā mea maka. Ke hōʻike ka hapa nui o nā ipu i nā hōʻailona o ka luhi i nā mahana kiʻekiʻe, mālama mau nā ipu hoʻoheheʻe keramika silicon carbide i ko lākou pololei geometric mua, a ʻo kēia ʻano "lōʻihi" ka maikaʻi i mahalo nui ʻia i ka ʻoihana hou.
Ua komo nui ʻo Shandong Zhongpeng i ke kahua o nā keramika silicon carbide no nā makahiki he nui, e hoʻoikaika mau ana i nā waiwai o nā mea ma o nā kaʻina hana hou, e hoʻolilo ana i kēlā me kēia ipu hao i hoa hana hilinaʻi. Ma ke ala o ka hahai ʻana i ka pono a me ka palekana loa, ke kākau nei nā keramika silicon carbide i kahi kūlana hou no nā ipu ʻoihana hou me ko lākou "ikaika paʻakikī".
