Corundum-mullite Chute
ʻO ka wehewehe pōkole:
Hāʻawi ʻo Corundum-mullite composite ceramic i ke kūpaʻa haʻalulu wela maikaʻi a me ka waiwai mechanical. Ma ka hoʻolālā waiwai a me ka hoʻolālā, hiki ke hoʻohana ʻia no ka mahana noi kiʻekiʻe o 1700 ℃ i ka lewa oxidizing.

Hāʻawi ʻo Corundum-mullite composite ceramic i ke kūpaʻa haʻalulu wela maikaʻi a me ka waiwai mechanical. Ma ka hoʻolālā waiwai a me ka hoʻolālā, hiki ke hoʻohana ʻia no ka mahana noi kiʻekiʻe o 1700 ℃ i ka lewa oxidizing.
He kūpono nā puʻupuʻu seramika no ka umu hoʻoheheʻe aluminika, ka papa ʻaina castin, a me ka lawe ʻana i nā aluminimu ma waena o ka umu hoʻoheheʻe a me ka kānana.
Pōmaikaʻi:
•Hoʻopili kemika maikaʻi
•Kūleʻa haʻalulu wela maikaʻi a me ka waiwai mechanical
•Anti-oxidation
•Kū'ē i ka hoʻoheheʻe metala

Mea Hana:
ʻAlumina Keramika
ʻO Alumina Ceramics ka mea hoʻohana nui i hoʻohana nui ʻia. Ma muli o kona hoʻopaʻa ʻana i ka ionic inter-atomic ikaika loa, hāʻawi ka alumina i ka hana maikaʻi ma ke ʻano o ka paʻa kemika a me ka wela, ka ikaika maikaʻi, ka wela a me nā hiʻohiʻona insulation uila ma ke kumukūʻai kūpono. Me ke ʻano o ka hoʻomaʻemaʻe a me ke kumu kūʻai haʻahaʻa loa i ka hana ʻana i nā mea waiwai hiki ke hoʻohana i ka alumina no nā noi ākea ma waena o nā ʻoihana like ʻole.
Mullite Ceramics Alumina
ʻAʻole hiki ke loaʻa ka Mullite ma ke ʻano no ka mea e hana wale ʻia i ka wela kiʻekiʻe, nā kūlana haʻahaʻa haʻahaʻa, no laila ma ke ʻano he mineral ʻoihana, pono e hoʻolako ʻia ka mullite e nā mea ʻokoʻa synthetic. He mea moho ikaika ʻo Mullite no nā seramika kiʻekiʻe i ke kaʻina hana ʻoihana no kāna mau mea wela a me ka mechanica maikaʻi: haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, kūpaʻa maikaʻi loa, kūpono i ka ikaika wela kiʻekiʻe a me ke kūpaʻa kūʻokoʻa ma lalo o nā wahi kemika paʻakikī.
ʻO ka alumina paʻa a me ka cordierite paʻa
Haʻahaʻa haʻahaʻa wai (0-5%)
Kiʻekiʻe kiʻekiʻe, Kiʻekiʻe wela wela
Nui kikoʻī ʻāpana ʻili, ʻoi aku ka maikaʻi o ka wela
ʻO ka ikaika anti-acid, anti-silicon, anti-paakai. Haʻahaʻa poloka haʻahaʻa
ʻO Silicon Carbide Ceramics
Kaulana ʻo Silicon carbide no kona paʻakikī, kiʻekiʻe melting-point a me ke kiʻekiʻe thermal conductivity. Hiki iā ia ke hoʻopaʻa i kona ikaika ma ke ana wela a hiki i 1400 °C a hāʻawi i ka pale ʻaʻahu maikaʻi loa a me ke kūpaʻa haʻalulu wela. Ua hoʻokumu maikaʻi ʻia a pālahalaha nui ʻia nā noi ʻoihana e like me nā kākoʻo catalyst a me nā kānana metala wela a i ʻole nā mea hoʻoheheʻe ʻia ma muli o kona haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa haʻahaʻa haʻahaʻa maikaʻi a me ke kūpaʻa mechanical a me kemika maikaʻi i nā wahi wela kiʻekiʻe.
Cordierite Ceramics
He ʻoi aku ka maikaʻi o ka Cordierite ma muli o ko lākou ʻano haʻahaʻa haʻahaʻa o ka hoʻonui wela (CET), i hui pū ʻia me ka refractoriness kiʻekiʻe a me ke kūpaʻa kemika kiʻekiʻe. No laila, hoʻohana pinepine ʻia e like me nā noi ʻoihana kiʻekiʻe, e like me: nā mea hoʻololi wela no nā mīkini turbine kinoea; nā mea hoʻoheheʻe honeycomb i loko o ka ʻōnaehana exhaust kaʻa.
Zirconia Oxide Ceramics Corundum
Hiki i nā Ceramics Zirconia ke lilo i mea kūpono no ka ikaika kiʻekiʻe a me ka paʻakikī i ka wā i hoʻohui ʻia ai nā haku mele kūpono, e like me: magnesium oxide (MgO), yttrium oxide, (Y2O3), a i ʻole calcium oxide (CaO), i hoʻohui ʻia i mea e hoʻomalu ai i kahi hoʻololi hoʻololi ʻē aʻe. nā noi.
ʻO Corundum Ceramics
1. maʻemaʻe kiʻekiʻe: Al2O3> 99%, kūpaʻa kemika maikaʻi
2. pale wela, hoʻohana lōʻihi ma 1600 °C, 1800 °C wā pōkole
3. ke kū'ē kū'ē wela a me ke kū'ē maikaʻi i ka māwae
4. hoolei pahee, kiʻekiʻe kiʻekiʻe, kiʻekiʻe maemae alumina
