Paipu pale ʻaʻahu i hoʻopaʻa ʻia me ka seramika silicon carbide
ʻO nā paipu pale ʻaʻahu Silicon carbide he mau paipu i hana nui ʻia me ka silicon carbide a he nui nā noi ma nā ʻano like ʻole. ʻO kāna hoʻokūkū koʻikoʻi penei:
（1）Hoʻokahuli Ola
I ka wā e lawe ai i nā mea abrasive e like me ka slurry a me ka lehu lanahu, he 10 mau manawa ke ola o nā metala, e hōʻemi ana i ka hoʻololi pinepine ʻana a me ka pohō downtime.
（2）He mau kūlana hana koʻikoʻi loa ia no nā mea a pau
Hana paʻa mai -50 ℃ a i 1600 ℃, me ke kūpaʻa ʻana i ka haʻalulu wela e pale aku i ka nahā ʻana, kūpono no nā hiʻohiʻona wela kiʻekiʻe e like me ka metallurgy a me ka ʻoihana kemika.
（3）Nui nā hoʻohana o hoʻokahi mea
Hoʻoponopono i nā pilikia nui ʻehā o ke komo ʻana, ka pala, ke kiʻekiʻe o ka mahana, a me ka pale ʻana i ka pahū i ka manawa like.
（4）Māmā a mālama i ka ikehu
Hoʻemi ka hoʻolālā māmā i nā kumukūʻai halihali a me ke kau ʻana, a ʻo ka helu friction haʻahaʻa e hōʻemi ana i ka hoʻohana ʻana i ka ikehu pumping.
ʻO ka pōmaikaʻi o nā paipu silicon carbide i hoʻohālikelike ʻia me nā mea kuʻuna:
| Ana hana | Paipu ʻaila silicon carbide | Nā paipu hao/palakiko |
| Ke kū'ē ʻana i ke komo ʻana | Paʻakikī 2800HV (5 manawa o ke kila), ʻoi aku ka lōʻihi o ke ola he 10 manawa ma mua o nā paipu ʻaʻole metala | He maʻalahi ka hao i ke komo a me ka haehae ʻana, ʻoiai he haʻahaʻa ka paʻakikī o ka plastic (PE<1 HV) |
| Mahana kiʻekiʻe ke kū'ē | Kūpaʻa i nā mahana kiʻekiʻe o 1600 ℃ a me ka haʻalulu wela (coefficient o ka hoʻonui wela 4 × 10 ⁻⁶/℃) | He maʻalahi ke kila kila i ka oxidation i nā mahana kiʻekiʻe, ʻoiai ʻo ka plastics he pale wela ma lalo o 80 ℃. |
| Ke kū'ē ʻana i ka palaho | Kūpaʻa i nā waikawa ikaika (waikawa sulfuric i hoʻopaʻa ʻia), nā kumu ikaika, a me ka pala o ka metala i hoʻoheheʻe ʻia | ʻIke ʻia ka ʻino o ke kila kila i ka wā e hōʻike ʻia ai i nā iona chloride, ʻoiai he palena ko ka pale ʻana o ka plastic i nā kemika. |
| Māmā | Ka nui o ka paʻa o 3.0~3.14 g/cm³ (60% māmā ma mua o ke kila) | He nui nā paipu hao a he nui ke kumukūʻai hoʻonohonoho |
| Hoʻonui Hana | Anti static (conductivity nāwaliwali), ka maʻemaʻe o ka papa semiconductor | Pono nā metala i ka mālama hou ʻana no ka pale ʻana i ka pahū ʻana, ʻoiai ua maʻalahi nā plastics i ka haumia. |
I ka pōkole, ʻaneʻane ʻaʻohe hopena ʻē aʻe no nā paipu silicon carbide i ka wā e lawe ana i nā mea hana ʻino loa a me nā mea kūpaʻa i ke komo ʻana e like me nā slurries acidic a me ka lehu kinoea flue wela kiʻekiʻe.
Inā he mau nīnau kāu, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa.
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.
