ʻO ka Silicon Carbide o Vickers Hardness o 2000kg/mm2, hāʻawi i ka palekana kiʻekiʻe no nā noi abrasion paheʻe
ʻO ka seramika carbide Silicon: ʻO ka paʻakikī o Moh he 9.0 ~ 9.2, ʻo Silicon Carbide o Vickers Hardness o 2100kg / mm2, hāʻawi i ka pale maikaʻi loa no nā noi abrasion paheʻe me ke kūpaʻa maikaʻi loa i ka erosion a me ka corrosion, kūpaʻa abrasion maikaʻi loa a me ka anti-oxidation. He 4 a 5 mau manawa ikaika ma mua o ka nitride bonded silicon carbide. ʻO ke ola lawelawe he 7 a 10 mau manawa ʻoi aku ka lōʻihi ma mua o ka mea alumina. ʻO ka MOR o RBSiC he 5 a 7 mau manawa o SNBSC, hiki ke hoʻohana ʻia no nā ʻano paʻakikī.
ʻO ke kūpaʻa ʻaʻahu Silicon carbide, ua synthesized ʻia mai ka silicon carbide a me ke kalapona i ka mahana kiʻekiʻe, no kekahi ʻano huahana silicon carbide. Hoʻohana nui ʻia nā ʻāpana kūpaʻa ʻaʻahu silicon carbide i ka hana mining, ka ʻoki ʻana i ka ore, ka nānā ʻana a me ka lawe ʻana i nā wai ʻaʻahu kiʻekiʻe, nā wai corrosive kiʻekiʻe, kūpono loa hoʻi no nā huahana mechanical me nā koi kikoʻī kiʻekiʻe a me nā sila, e like me ka pamu kaomi kiʻekiʻe, ka pamu magnetic etc. He ʻano hou o ka mea pale ʻaʻahu. Loaʻa i ka bushing pale ʻaʻahu silicon carbide i hoʻopaʻa ʻia ka hopena i nā ʻano o ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻaʻahu kiʻekiʻe, ke kūpaʻa hopena, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa waikawa a me ka alkali corrosion a pēlā aku, a ʻoi aku ka nui o ke ola lawelawe maoli ma mua o 6 mau manawa o ka polyurethane. He kūpono loa ia no ka hana o ka hoʻokaʻawale ʻana, ka noʻonoʻo a me ka dehydration o nā mea abrasive ikaika a me nā mea coarse-grained, ua hoʻopili pono ʻia i nā mines he nui. ʻO kā mākou hui he mea hoʻolako huahana keramika pale ʻaʻahu silicon carbide ʻoihana, ʻo ka paʻakikī ka lua wale nō i ka daimana, me ke kūpaʻa ʻaʻahu kiʻekiʻe, nā hiʻohiʻona ola lōʻihi. ʻO ka paipu kūpaʻa ʻaʻahu a me ke kuʻekuʻe i hana ʻia me ka lining pale ʻaʻahu silicon carbide, ʻo kona mānoanoa lining keramika he 6-35mm, ʻo ke ʻano e hoʻokomo i ka paipu keramika sintered i loko o ke kila caliber like. ʻōmole, me ke kāpili ma waenakonu. Loaʻa i nā paipu keramika pale ʻaʻahu nā waiwai aʻe i hoʻohālikelike ʻia me nā paipu pōhaku hoʻolei i lawe mua ʻia, nā paipu kila kila hoʻolei me ke koʻokoʻo a me nā paipu hui keramika.
Loaʻa i ka reaction bonded silicon carbide (RBSC) ka hana kūpaʻa maikaʻi loa i ka ʻaʻahu ʻana, nā waiwai maikaʻi i nā mahana kiʻekiʻe, ka pale ʻana i ka ʻino a me ka abrasive, hiki ke hoʻohana ʻia kēia mau waiwai i nā ʻano hana like ʻole e like me nā paipu liners, ceramic elbows, spray nozzles, shot blast nozzles a me nā ʻāpana hydrocyclone.
ʻOi aku ka lōʻihi o nā uhi ZPC ma mua o nā uhi tile a me nā metala. ʻOi aku ka pale ʻana o nā keramika silicon carbide ZPC i ka haʻalulu wela a me ka pale ʻana i ka abrasion e hopena ai i ka manawa holo lōʻihi a me ka hoʻemi ʻana i ka manawa downtime.
ʻO ka keramika silicion carbide i hoʻopaʻa ʻia me ka hopena (RBSIC) kahi mea kūpono e kū i ka ʻaʻahu, kahi mea kūpono loa no ka abrasive ikaika, nā ʻāpana coarse, ka hoʻokaʻawale ʻana, ka noʻonoʻo ʻana, ka dehydration a me nā hana ʻē aʻe. Ma muli o nā waiwai i luna, ʻo kaʻO ka paipu liner kuʻekuʻe lima / paipu liner RBSiC / SiSiC silicon carbidehiki ke pale pono i ka ʻāpana mai ke kapa kiʻekiʻe a me ka mahana i mea e hoʻolōʻihi ai i ke ola lawelawe o nā lako.

Ke kūlana hana o ka paipu pale ʻaʻahu silicon carbide ceramic
ʻO nā ʻano maʻamau o ka silicon carbide:
- Haʻahaʻa ka nui
- Ikaika kiʻekiʻe
- Ikaika maikaʻi o ka mahana kiʻekiʻe (Hoʻopaʻa ʻia ka hopena)
- Ke kū'ē'ē'ana i ka'okikene (Ho'opa'a'ia ka hopena)
- ʻO ke kūpaʻa haʻalulu wela maikaʻi loa
- Paʻakikī kiʻekiʻe a me ke kūpaʻa ʻaʻahu
- Ke kūpaʻa kemika maikaʻi loa
- Hoʻonui haʻahaʻa haʻahaʻa a me ke alakaʻi wela kiʻekiʻe
ʻO nā noi maʻamau o ka silicon carbide:
Hoʻohana nui ʻia lākou no ka hana me ke komo ʻana i ka mahana haʻahaʻa ma mua o ke ʻano o ka mahana kiʻekiʻe. ʻO nā noi SiC e like me nā injectors sandblasting, nā sila pamu wai kaʻa, nā bearings, nā ʻāpana pamu, a me nā make extrusion e hoʻohana ana i ka paʻakikī kiʻekiʻe, ke kū'ē ʻana i ka abrasion, a me ke kū'ē ʻana i ka corrosion o ka carbide o silicon.

ʻOihana metallurgy a me ka mana: ʻO ke kumu i hui pū ʻia ai kēia mau ʻoihana ʻelua no ka mea he ʻelua
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.
