Ke ʻimi nei i ka ʻaʻahu ʻaʻahu kūpaʻa Silicon Carbide: ʻO ke kiaʻi ʻike ʻole ʻia o nā lako hana

Ma ka ʻoihana ʻenehana, ʻike pinepine nā mea hana i nā pilikia kūlohelohe koʻikoʻi, a ʻo ka lole a me ka waimaka kekahi o nā pilikia nui. ʻAʻole hōʻemi wale ka lole a me ka waimaka i ka hana a me ka maikaʻi o nā mea hana, akā hiki ke alakaʻi i nā hemahema o nā mea hana, hoʻonui i nā kumukūʻai mālama a me ka manawa haʻahaʻa. ʻO ka puka ʻana mai oka lole ʻaʻahu kūpaʻa kilikakikaua like ia me kahi kahu ʻike ʻole ʻia, kūʻē i ka ʻaʻahu a hoʻonui i ke ola lawelawe o nā lako. I kēia lā, e wehe mākou i kāna pale pohihihi a e ʻimi i kāna kumu hana.
ʻO Silicon carbide (SiC) kahi hui i hoʻokumu ʻia i ʻelua mau mea, ke silika a me ke kalapona. He ʻokoʻa loa kona ʻano aniani, me nā ʻāpana kumu kumu i ulana ʻia ʻo SiC a me CSi tetrahedra. Hāʻawi kēia ʻano paʻa a paʻa i ka silicon carbide me nā waiwai maikaʻi loa, e like me ke kūpaʻa wela maikaʻi, ka pale ʻana i ka corrosion, ka paʻakikī kiʻekiʻe, a me ke kūpaʻa ʻaʻahu, e lilo ia i mea kūpono no ka hana ʻana i ka lole pale pale.
No laila, pehea ka hana ʻana o ka lining pale ʻaʻahu i hana ʻia i nā seramika carbide silicon sintered?
ʻO ka paʻakikī kiʻekiʻe e pale aku i ka ʻaʻahu: Reaction sintered silicon carbide ceramics he ultra-high hardness, ʻelua wale nō i ke daimana. Ke hoʻopili ʻia nā ʻāpana o waho i ka paia o loko o ka mea hana, hiki i ke kapa pale ʻaʻahu, me kona paʻakikī kiʻekiʻe, ke pale pono i ka pōʻino o kēia mau mana o waho, e like me ka pale ikaika, e hōʻemi nui i ke kiʻekiʻe o ka lole a hoʻonui i ke ola lawelawe o nā mea hana.
Paʻa kemika maikaʻi e kūʻē i ka corrosion: I loko o nā hiʻohiʻona ʻoihana he nui, ʻaʻole wale nā ​​​​mea hana e alo i ka ʻeha a me nā waimaka, akā pili pū kekahi me nā kemika like ʻole, e hoʻoweliweli ana i ka corrosion. Loaʻa ka paʻa kemika maikaʻi o ka reaction sintered silicon carbide ceramics a hiki ke pale pono i ka corrosion e nā mea kemika, no laila e hōʻoiaʻiʻo ai i ka hana maʻamau o ka lole pale pale i nā wahi kemika paʻakikī.

ʻO ke kūpaʻa wela kiʻekiʻe a me ka hiki ke hoʻololi i nā kaiapuni wela kiʻekiʻe: Hiki i kekahi mau kaʻina hana hana ʻoihana ke hoʻoulu i nā wela kiʻekiʻe, a lilo nā mea maʻamau i palupalu, deformed, a pohō paha i nā wela kiʻekiʻe. Eia nō naʻe, hiki i nā seramika silicon carbide i hoʻopili ʻia ke hiki ke piʻi i kahi mahana hana kiʻekiʻe loa o 1350 ℃ a hiki ke hoʻohana paʻa no ka manawa lōʻihi a hiki i kēia wela kiʻekiʻe. Hiki iā ia ke pale pono i nā ʻāpana a me nā ʻāpana mai ke komo ʻana i ka deformation thermal a me ka palupalu ma muli o nā wela kiʻekiʻe, e hōʻoiaʻiʻo ana e hiki ke hāʻawi i nā liner kūpaʻa ʻaʻahu i ka pale hilinaʻi no nā mea hana i nā wahi wela kiʻekiʻe.
Ke hoʻohālikelike ʻia me nā ʻano mea ʻē aʻe o nā mea ʻaʻahu-kūpaʻa lining, reaction sintered silicon carbide ceramic wear-resistant lining loaʻa nā pōmaikaʻi. ʻO kahi laʻana, ʻoi aku kona paʻakikī ma mua o nā seramika maʻamau e like me ka alumina a me ka zirconia, a ʻoi aku ka maikaʻi o ka pale ʻana; ʻOi aku ka maikaʻi o kona kūpaʻa kemika a me ke kūpaʻa wela kiʻekiʻe ma mua o kekahi mau mea kuʻuna, a hiki iā ia ke hoʻololi i nā wahi hana paʻakikī a koi.
Hoʻohana nui ʻia ka lining silicone carbide wear-resistant i nā ʻoihana like ʻole e like me ka mana, ke kila, nā seramika, nā kiln wela kiʻekiʻe, mining, lanahu, petroleum, kemika, a me nā mīkini hana. I kēia mau ʻoihana, mālama ia i nā mea hana he nui, hōʻoia i ka hana maʻalahi, a hōʻemi i nā kumukūʻai hana no nā ʻoihana.
He mea koʻikoʻi ka lining silicone carbide wear-resistant i ka ʻoihana ʻoihana ma muli o kāna kumu hana kūʻokoʻa a me ka hana maikaʻi loa. Ma ke ʻano he mea hana ʻoihana o ka reaction sintered silicon carbide ceramics, ua hoʻokō mau ʻo Shandong Zhongpeng i ka hāʻawi ʻana i nā mea kūʻai aku me nā huahana kiʻekiʻe, e kōkua ana i nā ʻoihana like ʻole e hoʻomaikaʻi i ka hana pono, a hoʻokō i ka hana kūpono. Inā makemake ʻoe i kā mākou huahana, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa a e hāʻawi pū mākou i ka hoʻomohala ʻana i ka ʻoihana.
