mea hana wili slicon carbide a me nā kaola
ʻOi aku ka ikaika o nā kaola a me nā wili keʻa ZPC-RBSiC (SiSiC) a ʻaʻohe deformations ʻoiai i ke ana wela kiʻekiʻe loa. A hōʻike pū nā kaola i ke ola hana lōʻihi. ʻO nā kaola nā lako umu kūpono loa no ka lole maʻemaʻe a me nā noi porcelain uila. Loaʻa iā RBSiC (SiSiC) ka conductivity thermal maikaʻi loa, no laila loaʻa ia e mālama i ka ikehu me ke kaumaha liʻiliʻi o ke kaʻa umu.
Hoʻohana ʻia nā kaola a me nā wili silicon carbide ma ke ʻano he mau kiʻina ukana i loko o nā umu hana porcelain, a hiki ke pani i ka papa silicon i hoʻopaʻa ʻia me ka oxide maʻamau a me ka pou mullite no ka mea he mau pono maikaʻi ko lākou e like me ka mālama ʻana i nā wahi, ka wahie, ka ikehu a me ka pōkole ʻana o ka manawa puhi, a ʻo ke ola o kēia mau mea he mau manawa o nā mea ʻē aʻe he lako umu kūpono loa ia. Hoʻohana nui ʻia ke kaola silicon carbide ma ke ʻano he mau lālā lawe ukana o ka umu tunnel, ka umu shuttle a me ka umu pālua. Hiki ke hoʻohana ʻia ma ke ʻano he lako umu i ka ʻoihana seramika a me ka refractory.
ʻO nā kaola me ka hiki ke halihali wela kiʻekiʻe o ka hoʻohana nui ʻana no ka manawa lōʻihi me ka ʻole o ke kūlou ʻana i ka deformation, kūpono loa no nā umu tunnel, ka umu shuttle, i loko o ka umu roller ʻelua papa a me nā ʻano hana halihali umu ʻoihana ʻē aʻe o ke kiʻikuhi. Hoʻopili nā kalapu i nā keramika i hoʻohana ʻia i kēlā me kēia lā, ka porcelain sanitary, ka keramika hale, nā mea Magnetic a me kahi ʻāpana puhi wela kiʻekiʻe o ka umu roller.

Nā ʻano:
*Ke kūpaʻa kiʻekiʻe o ka abrasion
* Ka hoʻokō pono ʻana o ka ikehu kiʻekiʻe
*ʻAʻohe deformation ma lalo o ke ana wela kiʻekiʻe
* Ka hoʻomanawanui mahana kiʻekiʻe loa 1380-1650 degere celsius
*Ke kū'ē i ka palaho
* Ikaika kūlou kiʻekiʻe ma lalo o 1100 degere: 100-120MPA
ʻO Shandong Zhongpeng Special Ceramics Co., Ltd kekahi o nā hoʻonā mea hou loa no ka silicon carbide ceramic ma Kina. ʻO ka keramika ʻenehana SiC: ʻO ka paʻakikī o Moh he 9 (ʻO ka paʻakikī o Moh hou he 13), me ke kūpaʻa maikaʻi loa i ka erosion a me ka corrosion, ke kūpaʻa abrasion maikaʻi loa a me ka anti-oxidation. ʻO ke ola lawelawe o ka huahana SiC he 4 a 5 mau manawa ka lōʻihi ma mua o 92% alumina mea. ʻO ka MOR o RBSiC he 5 a 7 mau manawa o SNBSC, hiki ke hoʻohana ʻia no nā ʻano paʻakikī. He wikiwiki ke kaʻina hana ʻōlelo, ʻo ka lawe ʻana e like me ka mea i hoʻohiki ʻia a ʻaʻohe lua o ka maikaʻi. Ke hoʻomau nei mākou i ka hoʻokūkū ʻana i kā mākou mau pahuhopu a hāʻawi i ko mākou mau naʻau i ke kaiāulu.
