Nā Kukui SiC
ʻO ka Reaction Bonded Silicon Carbide High Strength High Straightness Sisic/ Rbsic Rollers and Beams
Hoʻohana nui ʻia ka ʻōwili keramika silicon carbide reaction sintering no ka ʻoihana pākahi lithium, porcelain o kēlā me kēia lā, porcelain sanitary, nā keramika kūkulu hale a me nā mea magnetic, e like me ka umu roller, ke kuni wela kiʻekiʻe me ka umu kūpono, me ke ola lawelawe lōʻihi. Loaʻa iā ia ka ikaika wela kiʻekiʻe, ke kū'ē i ka haʻalulu wela, ke kū'ē i ke kolo wela kiʻekiʻe, ke kū'ē ikaika, ke kū'ē maikaʻi o ke komo ʻana. ʻO nā rollers 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, umu shuttle, i loko o ka umu roller ʻelua papa a me nā ʻano ukana umu ʻoihana ʻē aʻe o ka mōlina.
Hoʻopili nā kalapu i nā keramika i hoʻohana ʻia i kēlā me kēia lā, ka porcelain maʻemaʻe, ka keramika hale, nā mea Magnetic a me kahi ʻāpana ahi wela kiʻekiʻe o ka umu wili.

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.
