Ma ke "kahua kaua wela kiʻekiʻe" o ka ʻoihana hou, kū pinepine nā mea metala kuʻuna i nā pilikia e like me ka palupalu ʻana o ka deformation, oxidation a me ka corrosion. A he ʻano mea hou i kapa ʻiakeramika silicon carbideke lilo mālie nei i kahu koʻikoʻi o nā lako wela kiʻekiʻe me kona mau hiki nui ʻekolu o "ke kū'ē ʻana i ka mahana kiʻekiʻe, ka anti agitation, a me ka hoʻoili wela wikiwiki".
1, ʻO ka hiki maoli ke kū i nā mahana kiʻekiʻe
Loaʻa i nā keramika silikona carbide ka hiki ke kū i nā mahana koʻikoʻi. Hoʻopili paʻa ʻia kona mau ʻātoma ma o nā pilina covalent ikaika, e like me kahi pūnaewele ʻekolu-dimensional i ulana ʻia mai nā kaola kila, hiki ke mālama i ka kūpaʻa o ke kūkulu ʻana i nā wahi mahana kiʻekiʻe o 1350 ℃. ʻO kēia ʻano e maʻalahi ai iā ia ke hana i nā hana wela kiʻekiʻe lōʻihi e hiki ʻole i nā mea metala ke kū, e lilo ia i koho kūpono no nā kahua e like me ka uhi ʻana o ka umu a me ka pale wela o ka mokulele.
2. ʻO ka 'pale pale' e kū'ē i ka palaho oxidative
Ma lalo o ke kaomi pālua o ke kiʻekiʻe o ka mahana a me ka pāpaho ʻino, ʻili pinepine nā mea maʻamau i ka papa ma ka papa e like me ka hao i popopo. Hiki i ka ʻili o nā keramika silicon carbide ke hana i kahi papa pale mānoanoa o ka silicon dioxide, e like me ka uhi ʻana iā ia iho me ke kapa kila ʻike ʻole ʻia. ʻO kēia hiʻohiʻona "ho'ōla pono'ī" e hiki ai iā ia ke pale aku i ka oxidation wela kiʻekiʻe ma 1350 ℃ a pale aku i ka ʻino ʻana mai ka paʻakai heheʻe, ka waikawa a me ka alkali. Mālama ia i kahi kūlana kiaʻi o "ʻaʻohe pauka, ʻaʻohe hoʻokahe" i nā wahi ʻino e like me nā mea puhi ʻōpala a me nā mea hana kemika.
3. ʻO ka 'ʻelele' o ka wela
ʻAʻole e like me nā ʻano "wela a pulu" o nā keramika maʻamau, loaʻa i nā keramika silicon carbide ka conductivity thermal e like me nā metala. Ua like ia me kahi kahawai hoʻoheheʻe wela i kūkulu ʻia, hiki ke hoʻoili koke i ka wela i hōʻiliʻili ʻia i loko o ka hāmeʻa i waho. ʻO kēia hiʻohiʻona "ʻaʻohe hūnā wela" e pale pono i ka pōʻino o nā mea i hoʻokumu ʻia e nā mahana kiʻekiʻe kūloko, e hana ana i nā lako wela kiʻekiʻe e palekana a ʻoi aku ka pono o ka ikehu.
Mai nā umu ʻoihana a hiki i nā umu sintering silicon wafer photovoltaic, mai nā ʻōmole radiation nui a hiki i nā nozzles wela kiʻekiʻe, ke hoʻololi hou nei nā keramika silicon carbide i ke ʻano ʻenehana o ka ʻoihana wela kiʻekiʻe me ko lākou mau pono piha o ka "paʻa, kūpaʻa, a me ka hoʻoili wikiwiki". Ma ke ʻano he mea lawelawe lawelawe ʻenehana i komo nui i ke kahua o nā keramika holomua, ke hoʻomau nei mākou i ka hoʻolaha ʻana i nā holomua a me nā hana hou i ka hana mea, e ʻae ana i nā lako ʻoihana hou aku e mālama i kahi kūlana hana "mālie a mālie" i nā wahi koʻikoʻi.
——Ke uhaki nei i ka palena mahana o nā mea, ke hele pū nei mākou me ka ʻenehana!
