mea hoʻomehana sic
Hana ʻia nā mea hoʻomehana Sic mai ka SiCpowder ʻōmaʻomaʻo maikaʻi, i hoʻohui ʻia i kekahi mau mea hoʻohui e like me ka proportion material. Hoʻohālikelike ʻia me nā mea hoʻomehana metallic, loaʻa iā lākou kahi ʻano o nā hiʻohiʻona, e like me ke kiʻekiʻe o ka mahana, ka antioxidation, anticorrosion, hoʻonui wikiwiki i ka wela, haʻahaʻa haʻahaʻa o ka hoʻonui wela a pēlā aku. No laila, hoʻohana nui ʻia lākou i nā mea uila a me nā mea magnetic, nā seramika, ʻoihana metallurgy a pēlā aku.
ʻO nā mea hoʻomehana Sic Nā kikoʻī a me ka pae kūʻē

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. Hoʻomau mau mākou i ka hoʻokūkū i kā mākou mau pahuhopu a hāʻawi hou i ko mākou naʻau i ke kaiāulu.
