Kukui Silicon Carbide
Kukui RBSiC/SiSiCua hana nui ʻia me nā ʻāpana SiC a me ka silicon dioxide a me nā mea ʻē aʻe i sintered ma 1400-1500 ℃. ʻO kona ʻano hana e komo pū me nā ʻāpana SiC ma ke ʻano he aggregate a me SiO2 ma ke ʻano he pae hoʻopaʻa nui, a he mau ʻano ia o ka ikaika kiʻekiʻe, ke kūpaʻa maikaʻi o ka oxidation a me ke kūpaʻa haʻalulu wela.
Kaula RSiCHe mea keramika hana kiʻekiʻe me nā waiwai maikaʻi loa e like me ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, a me ke kūpaʻa wela kiʻekiʻe. ʻO kāna hana hana nui e pili ana i ʻelua mau ʻanuʻu: ʻo ka mua, ka sintering silicon carbide powder i loko o ke kino ʻōmaʻomaʻo ma lalo o nā kūlana wela kiʻekiʻe, a laila recrystallizing ma o ka hana wela e hana i ka mea keramika silicon carbide, a laila ʻoki a wili iā ia i ke ʻano i makemake ʻia.
No ke aha e koho ai i kā mākou mau kaola Silicon Carbide?
Pololei Ana Kiʻekiʻe:Loaʻa ka hoʻopilikino ʻana no ka lōʻihi, ka laulā, a me ka mānoanoa e like me kāu mau koi kikoʻī.
Kūlana Kiʻekiʻe a me ke Kūpaʻa:Ke hoʻohana nei i nā mea hana maka kiʻekiʻe a me ka kaohi maikaʻi e hōʻoia i ka hana mau.
Ola lawelawe lōʻihi:Me kahi ʻili laumania e kūʻē ana i ka pipili ʻana o nā mea a hōʻoia i ka lōʻihi o ke ola.
Kākoʻo piha:Ke hāʻawi nei i ke kōkua loea piha a me ka lawelawe ma hope o ke kūʻai aku, me nā ʻōlelo paipai no ka mea kūpono loa e pili ana i nā kūlana hana kikoʻī o kāu umu.
Nā Hiʻohiʻona:
Kukui Silicon Carbide / RBSiC i hoʻopaʻa ʻia:
(1) Ke Kaʻina Hana Hoʻopaʻa Hana Kiʻekiʻe:Hoʻohana i kahi kaʻina hana hoʻopili kahi e hui pū ʻia ai ka silicon carbide me ka silicon metala, e hopena ana i kahi ʻano paʻa a like.
(2) Ikaika Mekanika Kiʻekiʻe:Loaʻa ka ikaika nui loa a me ke kūpaʻa kiʻekiʻe i ka haʻalulu mechanical a me ka hopena.
(3) Kū'ē Kū'ē Wela Maika'i Loa:Loaʻa iā ia ka conductivity thermal kiʻekiʻe a me ka coefficient haʻahaʻa o ka hoʻonui thermal, e hōʻoiaʻiʻo ana i ke kūpaʻa haʻalulu thermal maikaʻi loa.
(4) Hoʻonā Kūpono-Kūpono:Hāʻawi i kahi kumukūʻai hoʻokūkū me ka ʻole o ka hoʻohaʻahaʻa ʻana i ka maikaʻi, e hāʻawi ana i kahi lakio uku-hana maikaʻi loa.
(5) Hoʻohana maʻalahi:He kūpono no ka hoʻohana ʻana i nā umu hoʻomau a me nā kūlana hana i hōʻike ʻia e nā loli mahana koʻikoʻi.
Kukui Silicon Carbide / RSiC i hoʻopili hou ʻia:
(1) ʻAno SiC Maʻemaʻe:Hoʻokumu ʻia ma o ke kaʻina hana recrystallization wela kiʻekiʻe, e hopena ana i kahi ʻano silicon carbide maʻemaʻe 100% me ka ʻāpana silicon metala ʻole.
(2) Ke Kū'ē Mahana Loa:Hōʻike i ke kūpaʻa wela kiʻekiʻe, hiki ke kū i nā mahana hana lōʻihi mai 1600°C a 1800°C.
(3) Ke kūpaʻa ʻoi aku ka maikaʻi ma mua o ka palaho a me ka ʻokikene:ʻO ke kūpaʻa kūikawā i ka oxidation a me ka corrosion kemika, e kūpono ai no nā wahi wela kiʻekiʻe loa.
(4) Ke kūpaʻa wela loa:Loaʻa iā ia kahi coefficient haʻahaʻa loa o ka hoʻonui ʻana o ka wela, e hāʻawi ana i ke kūpaʻa haʻalulu wela maikaʻi loa ma lalo o nā pōʻaiapuni hoʻomehana/hoʻoluʻu wikiwiki.
(5) Hoʻolōʻihi ʻia ke ola lawelawe:Hoʻolālā ʻia no ke ola lōʻihi, kūpono loa ia no nā umu ʻoihana nui, ke kiʻekiʻe o ka mahana, a me nā umu kaumaha.

Nā Nīnau i Nīnau Pinepine ʻia
Pono kōkua? E kipa aku i kā mākou mau kahua kākoʻo no nā pane i kāu mau nīnau!
He mea hana maoli mākou, ua loea kā mākou hale hana i ka hana ʻana i nā mea refractory no nā makahiki he 30 a ʻoi. Hoʻohiki mākou e hāʻawi i ke kumukūʻai maikaʻi loa, ka lawelawe mua a me ka lawelawe ma hope o ke kūʻai aku.
No kēlā me kēia kaʻina hana, loaʻa iā RBT kahi ʻōnaehana QC piha no ka hoʻohuihui kemika a me nā waiwai kino. A e hoʻāʻo mākou i nā waiwai, a e hoʻouna ʻia ka palapala hōʻoia maikaʻi me nā waiwai. Inā he mau koi kūikawā kāu, e hoʻāʻo mākou i ka maikaʻi loa e hoʻokō iā lākou.
Ma muli o ka nui, ʻokoʻa ka manawa hoʻouna. Akā ke hoʻohiki nei mākou e hoʻouna koke me ka maikaʻi i hōʻoia ʻia.
ʻOiaʻiʻo, hāʻawi mākou i nā laʻana manuahi.
ʻAe, ʻoiaʻiʻo, ua ʻoluʻolu ʻia ʻoe e kipa i ka hui ʻo RBT a me kā mākou huahana.
ʻAʻohe palena, hiki iā mākou ke hāʻawi i ka manaʻo maikaʻi loa a me ka hoʻonā e like me kou kūlana.
