Nā Piliki Silicon Carbide
ʻIke Huahana
Piliki kalapona silikaHe mea paʻakikī i hana ʻia me ka silicon carbide (SiC) ma ke ʻano he mea maka nui. Loaʻa iā ia nā ʻano o ka paʻakikī kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka ʻaʻahu, ka conductivity wela kiʻekiʻe a me ke kūpaʻa maikaʻi i ka corrosion. ʻO kāna ʻāpana nui ka silicon carbide, a ʻo ka nui ma waena o 72% a me 99%. ʻO nā ʻano maʻamau e komo pū me nā piliki silicon carbide i hoʻopaʻa ʻia me ka lepo, nā piliki silicon carbide i hoʻopaʻa ʻia me ka silicon nitride, nā piliki silicon carbide i hoʻopaʻa ʻia me ka Sialon, a pēlā aku.
1. Nā ʻano
Paʻakikī kiʻekiʻe:ʻO 9 ka paʻakikī Mohs o nā piliki silicon carbide, a he kiʻekiʻe loa kona kūpaʻa ʻana i ka ʻaʻahu.
Ka hoʻokele wela kiʻekiʻe:Loaʻa iā ia ka conductivity thermal kiʻekiʻe a kūpono ia no nā hanana e pono ai ka hoʻopuehu wikiwiki ʻana o ka wela.
Ke kū'ē'ē i ka palaho:He kūpaʻa maikaʻi kona i ka slag acidic a kūpono hoʻi no nā ʻano wela kiʻekiʻe a me nā ʻano kemika corrosion.
Ke kūpaʻa haʻalulu wela:He kūpaʻa maikaʻi kona i nā haʻalulu wela a hiki ke noho paʻa ma lalo o nā loli wikiwiki o ka mahana.
2. Hoʻokaʻawale ʻana
Hiki ke hoʻokaʻawale ʻia nā piliki carbide Silicon i nā ʻāpana penei e like me nā ʻano hoʻopili like ʻole:
Nā pōhaku lepo silicon carbide i hoʻopaʻa ʻia me ka lepo:Hoʻohana ʻia ka lepo ma ke ʻano he mea hoʻopaʻa, kūpono no nā hanana e pono ai ke alakaʻi wela kiʻekiʻe a me ke kūpaʻa haʻalulu wela.
Nā pōhaku lepo silicon carbide i hoʻopaʻa ʻia me ka silicon nitride:ua hoʻokuʻu ʻia ma o ka hopena nitriding, me ke kūpaʻa wela kiʻekiʻe maikaʻi loa a me ke kūpaʻa ʻana i ka ʻaʻahu.
Nā pōhaku lepo silicon carbide i hoʻopaʻa ʻia me ka sialon:i hui pū ʻia me ka pauka Si3N4 a me Al2O3, kūpono no nā wahi wela kiʻekiʻe a me ka palaho kemika.

ʻO Shandong Robert New Material Co., Ltd.Aia ma ke kūlanakauhale ʻo Zibo, ka moku ʻo Shandong, Kina, he kahua hana mea refractory. He ʻoihana hou mākou e hoʻohui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, ke kūʻai aku ʻana, ka hoʻolālā a me ke kūkulu ʻana i ka umu, ka ʻenehana, a me ka hoʻokuʻu aku i nā mea refractory. Loaʻa iā mākou nā lako piha, nā ʻenehana holomua, ka ikaika loea ikaika, ka maikaʻi o ka huahana maikaʻi loa, a me ka inoa maikaʻi. Uhi kā mākou hale hana ma mua o 200 ʻeka a ʻo ka hopena makahiki o nā mea refractory i hoʻohālikelike ʻia he 30000 tons a ʻo nā mea refractory i hoʻohālikelike ʻole ʻia he 12000 tons.
ʻO kā mākou huahana nui o nā mea refractory:nā mea kūpaʻa alkaline; nā mea kūpaʻa silicon alumini; nā mea kūpaʻa ʻano ʻole; nā mea kūpaʻa wela insulation; nā mea kūpaʻa kūikawā; nā mea kūpaʻa hana no nā ʻōnaehana hoʻolei mau.
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.
Ua hana mākou i nā mea refractory no nā makahiki he 30 a ʻoi, loaʻa iā mākou ke kākoʻo loea ikaika a me ka ʻike waiwai, hiki iā mākou ke kōkua i nā mea kūʻai aku e hoʻolālā i nā kilns like ʻole a hāʻawi i ka lawelawe hoʻokahi.
