Ma nā ʻoihana ʻoihana o ke kemika, ka ikehu, a me ka palekana o ke kaiapuni, ua like nā paipu me nā "kīʻaha koko" o nā lako, e lawe mau ana i nā mea nui like ʻole. Akā hiki ke kapa ʻia kekahi mau kūlana hana he "purgatory": hiki i nā wahi wela kiʻekiʻe ke hoʻoluʻolu i nā metala, hiki i nā waikawa ikaika a me nā alkalis ke hōʻino i nā paia paipu, a e hoʻomau ka wai i loaʻa nā ʻāpana i ka pala a me ka ʻaʻahu ʻana. I kēia manawa, pilikia pinepine nā paipu kuʻuna, ʻoiainā paipu silicon carbideke hoʻoponopono nei i kēia mau pilikia me ko lākou ʻano hiki ʻole ke uhaki ʻia.
Hānau Ikaika: ʻO ka ʻŌlelo Huna Hana o Silicon Carbide
Aia ka ikaika o nā keramika silicon carbide i kāna mau "genes mea" - ua ʻike ʻia nā keramika silicon carbide ʻo ia ka "daimana ʻeleʻele" o ka ʻoihana ʻoihana, me ʻekolu mau pono koʻikoʻi.
ʻOi aku kona paʻakikī ma mua o ka noʻonoʻo ʻana, ʻo ka lua wale nō ia o ke daimana a hiki i ka ʻelima manawa o ke kila maʻamau. Ke alo nei i ka ʻino wai e loaʻa ana nā ʻāpana paʻa, ua like ia me ke komo ʻana i kahi "pale pale pale" ʻaʻole maʻalahi ke komo lahilahi a ʻoi aku ka lōʻihi o ke ola lawelawe ma mua o nā paipu metala. I nā wahi wela kiʻekiʻe, he 'haku mālie' ia, ʻoiai i nā mahana o nā tausani degere Celsius, kūpaʻa kona ʻano, ʻaʻole like me ke kila kila e ʻike nei i ka hāʻule koke o ka ikaika i nā mahana kiʻekiʻe iki. A hiki iā ia ke kū i nā loli wela nui, a ʻaʻole ia e haki ʻoiai ke hōʻike koke ʻia i nā mea wela kiʻekiʻe i ka hoʻoilo.
ʻO ka mea koʻikoʻi loa, ʻo ia kona "talena anti-corrosion", hiki ke kapa ʻia he "immune" acid-base. Inā he mau waikawa ikaika e like me ka sulfuric acid i hoʻohuihui ʻia a me ka hydrofluoric acid, nā kiʻekiʻe o ka sodium hydroxide a me nā kumu ikaika, a i ʻole ka paʻakai paʻakai a me ka metala hoʻoheheʻe ʻia, he paʻakikī ke popopo i kona paia paipu. Hoʻoponopono kēia i ka pilikia nui o ka popopo pipeline a me ka leakage ma nā ʻano ʻoihana he nui.
Ke hoʻohālikelike ʻia me ke kuʻuna: no ke aha i ʻoi aku ai ka hilinaʻi?
Ke hoʻohālikelike ʻia me nā pipelines kuʻuna, hiki ke ʻōlelo ʻia ka pono o nā pipelines silicon carbide ʻo ia ka "dimensionality reduction strike".
He palupalu nā paipu hao i nā mahana kiʻekiʻe a hiki ke ʻinoʻino electrochemical ke hōʻike ʻia i ka waikawa a me ka alkali. Hiki i nā mea haumia ke piʻi aʻe i ka wā o ka lawe ʻana i nā mea hana pololei, e hoʻopilikia ana i ko lākou maikaʻi. ʻOiai he kūpaʻa ka ʻenekinia i ka pala, he haʻahaʻa loa ko lākou palena kūpaʻa wela, ʻoi aku ka liʻiliʻi ma mua o 200 ℃, a he palupalu hoʻi lākou i ka ʻelemakule a me ka haki ʻana. Kūpaʻa nā paipu keramika maʻamau i nā mahana kiʻekiʻe a me ke komo ʻana, akā he palupalu loa lākou a hiki ke haki me nā loli iki o ka mahana.
A pale pono nā paipu silicon carbide i kēia mau hemahema, me nā hiki nui ʻekolu o ka paʻakikī, ke kūpaʻa wela, a me ke kūpaʻa ʻana i ka pala e hoʻohana piha ʻia ana, kahi e hoʻokō pono ai i nā koi koʻikoʻi o ka ʻoihana hou no ka "lōʻihi, kūpaʻa, a me ka mālama liʻiliʻi" o nā paipu.
Ke komo ʻana i ka ʻoihana: Hiki ke loaʻa kona alo ma nā wahi āpau
I kēia mau lā, ua lilo nā paipu silicon carbide i "maʻamau" no nā kūlana hana koʻikoʻi he nui. I loko o ka ʻoihana kemika, kuleana ia no ka lawe ʻana i nā ʻano waikawa a me nā alkalis i hoʻopaʻa ʻia me ka ʻole o ka hoʻololi pinepine a me ka mālama ʻana; I loko o ka ʻōnaehana desulfurization a me denitrification o nā mea kanu mana, hiki iā ia ke kū i ke kiʻekiʻe o ka mahana a me ke kiʻekiʻe o ka haʻahaʻa i nā wahi corrosive, a hiki i kona ola lawelawe ke ʻoi aku ma mua o 10 mau makahiki.
I loko o nā hale hana semiconductor, ʻo kona maʻemaʻe kiʻekiʻe loa e hōʻoiaʻiʻo ana i ka haumia ʻole i ka lawe ʻana i nā kinoea maʻemaʻe kiʻekiʻe, e lilo ia i "kūlana gula" no ka hana ʻana i nā ʻāpana; I loko o ka ʻoihana metallurgical, hiki iā ia ke lawe i nā ʻāpana metala wela kiʻekiʻe a me nā pauka ore me ka makaʻu ʻole i ka ʻino a me ke komo ʻana. ʻOiai i loko o ka ʻoihana aerospace, ʻaʻole hiki i nā ducts kinoea wela kiʻekiʻe o nā mīkini rocket ke hana me ka ʻole o kā lākou kākoʻo.
Me ka holomua o ka ʻenehana kūloko, ua emi nui ke kumukūʻai o nā paipu silicon carbide, a hiki ke hoʻololi ʻia i nā kahua e kū mai ana e like me ka ikehu hydrogen a me ka aerospace ma o nā kaʻina hana kemika i hana ʻia. Ke hoʻohana nei kēia 'Diamond Warrior' i nā paipu ʻoihana i kona ikaika e pale i ka hana paʻa o nā ʻoihana like ʻole.
