ʻO ka paipu pale seramika Silicon carbide: ke "kahu paʻa" i nā wahi ʻoihana

I nā hiʻohiʻona he nui o ka hana ʻoihana, ʻo nā ʻano ʻino e like me ke kiʻekiʻe o ka mahana, ka pala, a me ke komo ʻana e hoʻāʻo pinepine i ke kūpaʻa o nā ʻāpana lako like ʻole.Nā paipu pale seramika silikona carbide, ma ke ʻano he mea nui e kiaʻi mālie ana i nā ʻāpana koʻikoʻi o nā lako, ke pāʻani nei i kahi kuleana nui i nā ʻoihana he nui me ko lākou mau pono kūikawā. ʻAʻohe ona ʻano paʻakikī, akā me ka "resilience" ma ke ʻano he ʻano koʻikoʻi, ua lilo ia i "kiaʻi" hilinaʻi i nā ʻano ʻoihana.
ʻO ka pōmaikaʻi nui o nā paipu pale seramika silicon carbide mai ko lākou mau waiwai kūikawā. ʻO ka mea mua, he kūpaʻa wela kiʻekiʻe loa ia a hiki ke mālama i ke kūpaʻa kūkulu ʻana i nā wahi wela kiʻekiʻe ma luna o 1000 degere Celsius, me ka ʻole o ka deformation a i ʻole ka hōʻino. Hiki i kēia hiʻohiʻona ke lawelawe maʻalahi i nā hiʻohiʻona hana wela kiʻekiʻe e like me ka metallurgy a me ka ʻenekinia kemika, e kūkulu ana i kahi "pale pale" hilinaʻi no nā ʻāpana koʻikoʻi e like me nā sensor a me nā mea hoʻomehana i loko. ʻO ka lua, he maikaʻi loa kona kūpaʻa ʻana i ka corrosion, a he paʻakikī no nā media kemika e like me nā waikawa ikaika a me nā alkalis, a me nā kinoea ʻōpala ʻoihana a me nā wai e hōʻino nui iā ia. ʻO kēia hiki "anti-corrosion" e hoʻolōʻihi nui i ke ola lawelawe o ka paipu pale a hoʻemi i ke alapine a me ke kumukūʻai o ka mālama ʻana i nā lako. Eia kekahi, he paʻakikī kiʻekiʻe ka mea seramika silicon carbide a he kūpaʻa maikaʻi hoʻi i ka ʻaʻahu. I nā hiʻohiʻona kahi e maʻalahi ai ka friction e like me ka lawe ʻana i nā mea a me ka hoʻoulu ʻana i ka mechanical, hiki iā ia ke pale aku i ka ʻaʻahu, mālama i kona kūpaʻa kūkulu, a pale i ka hoʻopilikia ʻana i ke kaʻina hana ma muli o ka ʻaʻahu ʻana o nā ʻāpana.

Ma ke ʻano o nā hiʻohiʻona kūpono, ua ākea loa ka laulā o ka hoʻohana ʻana i nā paipu pale silicon carbide ceramic. I ka ʻoihana metallurgical, hiki iā ia ke pale i nā mea ʻike mahana e ana pololei i ka mahana i loko o nā umu wela kiʻekiʻe no ka hana kila a me ka hana hao; Ma ke kahua o ka ʻenekinia kemika, hiki iā ia ke pale i ka ʻino ʻana o nā hopena acidic a me alkaline a hāʻawi i ka pale no ka nānā ʻana i nā ʻāpana i loko o nā ipu hopena a me nā pipeline; I ka ʻoihana mana, hiki ke hoʻohana ʻia no ka pale ʻana i nā ʻāpana o nā lako wela kiʻekiʻe e like me nā paila a me nā turbine, e hōʻoiaʻiʻo ana i ka hana mau a paʻa o ka uila; Eia kekahi, hiki ke ʻike ʻia kona alo i nā wahi wela kiʻekiʻe a me nā ʻino i nā ʻoihana e like me ka pale ʻana i ke kaiapuni, nā mea kūkulu hale, a me ka ikehu hou. Inā he puhi wela kiʻekiʻe, ka pala kemika, a i ʻole ka ʻaʻahu mechanical, inā he ʻano ʻino ia e pono ai ka pale ʻana, hiki i nā paipu pale silicon carbide ceramic ke hilinaʻi i ko lākou mau pono ponoʻī e hōʻoia i ka hana maʻamau o nā lako.
Ma ke ʻano he ʻāpana pale koʻikoʻi i ka hana ʻoihana, ua lilo nā paipu pale silicon carbide i "nā kiaʻi paʻa" o nā lako i nā ʻano ʻino ma muli o ko lākou mau pono koʻikoʻi o ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa i ka pala, ke kūpaʻa ʻana i ka ʻaʻahu, a me ka paʻakikī maikaʻi. Hāʻawi ia i kahi hōʻoia no ka hana paʻa ma nā ʻoihana like ʻole me kāna hana maʻalahi a me ka ʻole o ka hoʻonani ʻana, a hiki nō hoʻi i nā poʻe hou aku ke hoʻomaopopo i ka waiwai kūikawā o nā mea seramika silicon carbide. Me ka hoʻomohala mau ʻana o ka ʻenehana ʻoihana, e hoʻomau ka hoʻonui ʻana o nā hiʻohiʻona noi o nā paipu pale silicon carbide, e pāʻani ana i kā lākou kuleana "pale" ma nā kahua hou aʻe a hoʻokomo i ka mana mau loa i ka hana pono a palekana o ka hana ʻoihana.
