Kaola SiC
ʻO ka hoʻopaʻa ʻana i ka Silicon Carbide i hoʻopaʻa ʻia i ka ikaika kiʻekiʻe kiʻekiʻe ʻo Sisic/Rbsic Rollers a me nā kaola.
Hoʻohana nui ʻia ʻo Reaction sintering silicon carbide ceramics roller no ka ʻoihana pākaukau lithium, porcelain i kēlā me kēia lā, porcelain sanitary, kūkulu hale a me nā mea magnetic, e like me ka roller kiln, ke ahi wela kiʻekiʻe me ka kiln maikaʻi, me ke ola lōʻihi. Loaʻa iā ia ka ikaika wela kiʻekiʻe, ke kūpaʻa haʻalulu wela, ke kūpaʻa kiʻekiʻe o ka creep, ke kūpaʻa ikaika, ke kūpaʻa maikaʻi. i loko o ʻelua – papa kiln wili a me nā ukana ʻē aʻe o ka umu ahi - e halihali ana i ke ʻano o ke kiʻi.
Hoʻohana ʻia nā hui i kēlā me kēia lā - nā seramika i hoʻohana ʻia, porcelain maʻemaʻe, Building Ceramic, Material Magnetic a me kahi kiʻekiʻe kiʻekiʻe kiʻi ahi o ka roller kiln.

ʻO Shandong Zhongpeng Special Ceramics Co., Ltd kekahi o ka silicon carbide ceramic mea hoʻonā hou i Kina. ʻO ka ʻenehana loea SiC: ʻO 9 ka paʻakikī o Moh (ʻo 13 ka paʻakikī o New Moh), me ke kūpaʻa maikaʻi loa i ka erosion a me ka corrosion, abrasion maikaʻi loa - kūpaʻa a me ka anti-oxidation. ʻO ke ola lawelawe o ka huahana SiC he 4 a 5 mau manawa lōʻihi ma mua o 92% alumina mea. ʻO ka MOR o RBSiC he 5 a 7 mau manawa o ka SNBSC, hiki ke hoʻohana ʻia no nā ʻano paʻakikī. He wikiwiki ke kaʻina hana, ʻo ka hāʻawi ʻana e like me ka mea i ʻōlelo ʻia a ʻoi aku ka maikaʻi o ka lua.
