hoʻohana i ka paipu seramika kūpaʻa
Silicon carbide ceramic: ʻO ka paʻakikī o Moh he 9.0 ~ 9.2, me ke kū'ē maikaʻi loa i ka erosion a me ka corrosion, maikaʻi abrasion-kū'ē a me ka anti-oxidation. He 4 a 5 mau manawa ʻoi aku ka ikaika ma mua o ka nitride paʻa silicon carbide. ʻO ke ola lawelawe he 7 a 10 mau manawa lōʻihi ma mua o nā mea alumina. ʻO ka MOR o RBSiC he 5 a 7 mau manawa o ka SNBSC, hiki ke hoʻohana ʻia no nā ʻano paʻakikī.
ʻO ke kūpaʻa ʻana o ka silicon carbide, ua synthesized mai ka silicon carbide a me ke kalapona i ke kiʻekiʻe wela, no ke ʻano o ka huahana silicon carbide. nā wai, kūpono loa no nā huahana mechanical me nā koi kiʻekiʻe a me ka hoʻopaʻa ʻana i nā koi, e like me ke kaomi kiʻekiʻe, ʻo ka pauma magnetic etc. He ʻano hou o ka lole pale lole. ʻaʻahu kū'ē, kū'ē kū'ē, kū'ē wela kiʻekiʻe, kaʻakika a me ka alkali corrosion kū'ē a pela aku, a me ke ola lawelawe maoli i oi aku mamua o 6 mau manawa o ka polyurethane. He kūpono loa ia no ka hana o ka hoʻokaʻawaleʻana, ka noʻonoʻo a me ka dehydration o ka abrasive ikaika a ʻO nā mea i kālai ʻia, ua hoʻohana maikaʻi ʻia i nā mines he nui. ʻO kā mākou hui he ʻoihana ʻoihana silika carbide kūʻai aku i nā huahana seramika, ʻoi aku ka lua o ka daimana, me ke kūpaʻa lole kiʻekiʻe, nā hiʻohiʻona ola lōʻihi. me ka silika carbide lole pale pale pale, kona seramika lining mānoanoa he 6-35mm, ka hale e hoʻokomo i ka sintered ceramic paipu i loko o ka like caliber kila paipu, me ke kāpili i ka middle.Wear kū'ē ceramic paipu i kēia mau waiwai i hoohalikeia me nā paipu pōhaku hoʻoheheʻe mua ʻia, nā paipu kila hoʻoheheʻe ʻia i ka lole a me nā paipu hoʻohuihui ceramic.
ʻO ka Reaction bonded silicon carbide (RBSC) he hana maikaʻi loa i ka lole, nā waiwai maikaʻi i nā mahana kiʻekiʻe, maikaʻi ka erosion a me ke kūpaʻa abrasive, hiki ke hoʻohana ʻia kēia mau waiwai i nā ʻano like ʻole e like me nā pipe liners, ceramic elbow, spray nozzles, shot blast nozzles. nā ʻāpana hydrocyclone.
ʻOi aku ka lōʻihi o nā linings ZPC ma mua o nā laina ʻili a me nā mea hao. ʻO ka ZPC silicon carbide ceramics he kūʻokoʻa haʻalulu wela a me ka abrasion resistant e hopena i nā manawa holo lōʻihi a hoʻemi ʻia ka manawa hoʻomaha.
ʻO ka hopena i hoʻopaʻa ʻia i ka silicion carbide ceramic (RBSIC) kahi mea kūpono kūpono no ka abrasive ikaika, nā ʻāpana koʻikoʻi, ka hoʻokaʻawale ʻana, ka ʻike ʻana, dehydration a me nā hana ʻē aʻe. Ma muli o nā waiwai i luna, kaRBSiC / SiSiC silicon carbide liner kuʻekuʻe / liner tubehiki ke pale pono i ka ʻāpana mai ka lole kiʻekiʻe a me ka mahana e hoʻolōʻihi i ke ola lawelawe o nā mea hana.

ʻO ke kūlana hana o ka paipu paʻa paʻa kilika carbide ceramic
ʻO nā hiʻohiʻona silicon carbide maʻamau:
- haʻahaʻa haʻahaʻa
- Ka ikaika kiʻekiʻe
- ʻO ka ikaika wela kiʻekiʻe maikaʻi (Reaction bonded)
- Ke kū'ē i ka ʻokiʻoki (Hoʻopaʻa ʻia)
- Kūleʻa haʻalulu wela maikaʻi
- ʻO ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻaʻahu
- Kūʻē kemika maikaʻi loa
- ʻO ka hoʻonui haʻahaʻa haʻahaʻa a me ka conductivity wela kiʻekiʻe
Loaʻa nā noi carbide silicon maʻamau:
Hoʻohana nui ʻia lākou no ka hana ʻana me ka ʻaʻahu i ka wela haʻahaʻa ma mua o ka hana wela kiʻekiʻe. ʻO nā noi SiC e like me nā injectors sandblasting, nā sila pauma wai kaʻa, nā bearings, nā ʻāpana pauma, a me nā make extrusion e hoʻohana ana i ka paʻakikī kiʻekiʻe, ke kūpaʻa abrasion, a me ke kūpaʻa corrosion o ka carbide o ke silika.
- Hoʻopaʻa a neʻe i nā ʻāpana turbine
- Sila, bearings, pump vanes

Metallurgy a me ka ʻoihana mana: ʻO ke kumu i hui pū ʻia ai kēia mau ʻoihana ʻelua ma muli o ka loaʻa ʻana o nā ʻoihana ʻelua
ʻO Shandong Zhongpeng Special Ceramics Co., Ltd ʻo ia 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 i ko mākou naʻau i ke kaiāulu.
