Ma nā ʻoihana ʻoihana o ke kemika, ka ikehu, a me ka mālama ʻana i ke kaiapuni, ua like nā pipeline me nā "moku koko" o nā lako, e lawe mau ana i nā ʻano media kī. Akā, hiki ke kapa ʻia kekahi mau kūlana hana he "purgatory": hiki i nā wahi wela kiʻekiʻe ke hana i nā metala palupalu, hiki i nā waikawa ikaika a me nā alkalis ke hoʻopōʻino i nā paia paipu, a e hoʻomau ʻia nā wai i loko o nā ʻāpana. I kēia manawa, hakakā pinepine nā pipeline kuʻuna, ʻoiaipaipu kalapona silikake hoʻoponopono nei i kēia mau pilikia me ko lākou ʻano hiki ʻole ke haki.
Hānau ikaika: ʻo ka ʻōlelo huna hana o Silicon Carbide
ʻO ka ikaika o ka silicon carbide ceramics aia i loko o kāna mau "genes material" - ua ʻike ʻia nā silicon carbide ceramics ʻo "black diamond" o ka ʻoihana ʻoihana, me ʻekolu mau pono kumu.
ʻOi aku kona paʻakikī ma mua o ka noʻonoʻo ʻana, ʻelua wale nō i ka daimana a hiki i ʻelima mau manawa ma mua o ke kila maʻamau. Ke alo i ka wai erosion i loaʻa nā ʻāpana paʻa, ua like ia me ke komo ʻana i kahi "ʻaʻahu pale pale" ʻaʻole hiki ke maʻalahi a ʻoi aku ka lōʻihi o ke ola ma mua o nā paipu metala. Ma nā wahi wela kiʻekiʻe, he 'kumu mālie' ia, ʻoiai i nā mahana o nā kaukani degere Celsius, paʻa mau kona hale, ʻaʻole like me ke kila kila e ʻike i ka hāʻule koke ʻana o ka ikaika ma nā mahana kiʻekiʻe iki. A hiki iā ia ke pale i nā hoʻololi wela nui, ʻaʻole ia e haki ʻoiai ke hōʻike koke ʻia i ka media wela kiʻekiʻe i ka hoʻoilo.
ʻO ka mea koʻikoʻi ʻo kāna "kālena anti-corrosion", hiki ke kapa ʻia he "immune" acid-base. Inā he ʻakika ikaika e like me ka waikawa sulfuric concentrated a me ka waika hydrofluoric, nā kiʻekiʻe kiʻekiʻe o ka sodium hydroxide a me nā kumu ikaika, a i ʻole ka paʻakai paʻakai a me ka metala hoʻoheheʻe ʻia, paʻakikī ke hoʻopau i kona pā paipu. Hoʻopau kēia i ka pilikia nui o ka pipeline corrosion a me ka leakage i nā hanana ʻoihana he nui.
Ke hoʻohālikelike ʻia me nā kuʻuna: no ke aha i ʻoi aku ka hilinaʻi?
Ke hoʻohālikelike ʻia me nā pipeline kuʻuna, hiki ke ʻōlelo ʻia ka maikaʻi o nā pipeline silicon carbide he "dimensionality reduction strike".
Hiki i nā paipu metala ke palupalu i nā wela kiʻekiʻe a hiki ke hana i ka corrosion electrochemical ke ʻike ʻia i ka waikawa a me ka alkali. Hiki i nā mea haumia ke hoʻoheheʻe i ka wā o ka lawe ʻana i ka media precision, e pili ana i ko lākou maikaʻi. ʻOiai ʻo nā paipu plastik ʻenekinia he pale ʻino, haʻahaʻa loa ko lākou palena pale wela, ʻoi aku ka liʻiliʻi ma mua o 200 ℃, a hiki nō hoʻi i ka ʻelemakule a me ka haki ʻana. Kūleʻa nā paipu seramika maʻamau i nā wela kiʻekiʻe a me ka ʻaʻahu ʻana, akā palupalu loa lākou a hiki ke pohā me nā loli liʻiliʻi o ka wela.
A pale maikaʻi nā paipu carbide silicon i kēia mau hemahema, me ka hoʻohana piha ʻana i nā mana nui ʻekolu o ka paʻakikī, ka pale wela, a me ka pale ʻana i ka corrosion, e hoʻokō pono ana i nā koi kumu 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. I ka ʻoihana kemika, ʻo ia ke kuleana no ka lawe ʻana i nā ʻakika concentrated a me nā alkali me ka ʻole o ka hoʻololi pinepine ʻana a me ka mālama ʻana; I ka desulfurization a me ka denitrification nenoaiu o ka mana mea kanu, hiki ke ku i ke kiʻekiʻe wela a me kiʻekiʻe humidity corrosive kaiapuni, a me kona ola lawelawe hiki ke oi 10 makahiki.
I loko o nā hale hana semiconductor, ʻo kona hoʻomaʻemaʻe ultra-kiʻekiʻe e hōʻoia i ka pollution ʻole i ka lawe ʻana i nā kinoea hoʻomaʻemaʻe kiʻekiʻe, e lilo ia i "kūlana gula" no ka hana chip; I ka ʻoihana metallurgical, hiki iā ia ke lawe i nā ʻāpana metala wela kiʻekiʻe a me nā pauka oka me ka makaʻu ʻole i ka erosion a me ka lole. ʻOiai i loko o ka ʻoihana aerospace, ʻaʻole hiki ke hana i nā ducts gas wela wela o nā ʻenekini rocket me ke kākoʻo ʻole.
Me ka holomua o ka ʻenehana kūloko, ua emi nui ke kumukūʻai o nā pipeline 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 kemika maʻamau. Ke hoʻohana nei kēia 'Diamond Warrior' i nā paipu ʻoihana i kona ikaika e mālama i ka hana paʻa o nā ʻoihana like ʻole.
