Nā liners keramika silikona carbide

ʻO ka uhi pale ʻaʻahu silikon carbide

Nā Hiʻohiʻona Hoʻolālā o nā Liners Hoʻopaʻa-Paʻa Silicon Carbide (SiC):

（1）Hoʻolālā Ala Kahe i Hoʻomaʻamaʻa ʻia

ʻO kahi ʻano laumania a maʻalahi hoʻi mai ke komo ʻana a i ka puka ʻana e hōʻemi ana i ke kūʻē ʻana o ke kahe, e hiki ai i nā liner SiC ke hoʻololi i nā noi ʻoihana like ʻole.

（2）Atomization holomua

ʻAno Hana Hoʻohuihui ʻia nā wai i loko o nā kulu liʻiliʻi ma o nā kuʻi tangential me nā ʻili helical e hoʻohaiki mālie ana o ka liner SiC, e hōʻoiaʻiʻo ana i ka hoʻolaha like ʻana o ka pīpī.

（3）ʻAno paʻa, ʻaʻohe ʻūpā

Hoʻopau kahi kahawai kahe pololei, ʻaʻohe kumu i nā mea ālai i loko, e hoʻonui ana i ka kahe o ke wai i loko o nā ana paipu i kaupalena ʻia me ka pale ʻana i nā mea ālai.

（4）Nā ʻAno Pīpī Pālua no ka Hoʻonui ʻana i ka Pono

Kākoʻo i nā ʻano pīpī solid-cone a me hollow-cone, e hāʻawi ana i nā kihi uhi ākea a me ka hana anti-clogging no nā hana hana kiʻekiʻe.

Nā pono koʻikoʻi i hoʻohālikelike ʻia me nā mea ʻē aʻe:

（1）Ke kū'ē ʻana i ka ʻaʻahu like ʻole

Paʻakikī: Loaʻa i nā liner SiC kahi paʻakikī Mohs o 9.5 (vs. 8.0 no nā keramika alumina, 6.0 no ke kila chromium kiʻekiʻe), e hiki ai iā lākou ke kū i ka ʻaʻahu abrasive koʻikoʻi i nā slurries mining, lehu lanahu, a me nā pauka metala.

Ka lōʻihi o ke ola: ʻOi aku ke ola lawelawe ma mua o 5-10 × nā mea kuʻuna (e like me nā liners laholio a polyurethane paha) i nā noi hopena kiʻekiʻe e like me nā wili pōpō a i ʻole nā ​​​​pumps slurry.

（2）Ka palaho a me ka inertness kemika

Ke Kūʻē ʻAkika/Alkali：Ke kūʻē nei i ka waikawa sulfuric i hoʻohuihui ʻia (98%), sodium hydroxide (50%), a me nā paʻakai heheʻe (e laʻa me NaCl-KCl ma 800°C), ʻoiai ʻo nā metala e pala koke a hōʻino ʻia nā polymers.

ʻAʻohe haumia：ʻO ka ʻili non-reactive e hōʻoia i ka maʻemaʻe i ka hana semiconductor a i ʻole ka hana lithium, ʻaʻole e like me nā liners kila i maʻalahi i ka leaching ion.

(3) Paʻa o ka Mahana Loa

Ke kūpaʻa wela: Hana mau ma 1,600°C (e kū'ē i ka palena o ka alumina 1,200°C) me ka hoʻonui wela liʻiliʻi (CTE: 4.0×10⁻⁶/℃), e pale ana i ka nahā ʻana i loko o nā umu a i ʻole nā ​​umu hoʻoheheʻe.

Ke Kū'ē ʻana i ka Haʻalulu Wela：Mālama i ka kūpaʻa o ke kūkulu ʻana ma lalo o nā loli wikiwiki o ka mahana (e laʻa me ka hoʻopau ʻana mai 1,000°C a i ka mahana o ka lumi), ʻaʻole e like me nā keramika palupalu.

(4) Ka Pono o ka Ikehu a me ka Hoʻolālā Māmā

Haʻahaʻa Haʻalulu: Hoʻemi ka ʻili SiC i hoʻopili ʻia (Ra <0.1 μm) i ke kūpaʻa wai ma 30-50% e kūʻē i nā liner kila ʻino, e hōʻemi ana i nā kumukūʻai ikehu pamu.

Mālama Kaumaha：ʻO ka nui o 3.1 g/cm³ (vs. 7.8 g/cm³ o ke kila) e maʻalahi ai ke kau ʻana a kākoʻo i nā lako māmā i nā ʻāpana hana aerospace a i ʻole nā ​​​​​​ʻāpana hana kelepona.

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.
