Ma nā hale hana he nui, kū mālie kekahi mau paipu i nā kūlana hana ʻino loa: ke kiʻekiʻe o ka mahana, ka pala ikaika, a me ke komo ʻana. ʻO lākou nā 'kīʻaha koko ʻoihana' e hōʻoiaʻiʻo ana i ka hana mau a paʻa. I kēia lā e kamaʻilio mākou e pili ana i ka mea koʻikoʻi ma kēia ʻano paipu -paipu keramika silicon carbide.
Manaʻo ka poʻe he nui i ka "brittle" ke lohe lākou i ka "ceramic". Akā, ʻoi aku ka paʻakikī o nā keramika silicon carbide ʻoihana i ka "paʻakikī" a me ka "paʻa". He kiʻekiʻe loa kona paʻakikī, a ʻoi aku ka nui o kona kūpaʻa i ka ʻaʻahu ma mua o nā metala a me ka rubber. Hiki iā ia ke kū i ka erosion wai wikiwiki e loaʻa ana nā ʻāpana paʻa no ka manawa lōʻihi; He paʻa loa nā waiwai kemika a hiki ke kū i ka erosion o nā waikawa ikaika like ʻole, nā kumu ikaika, a me nā paʻakai; I ka manawa like, hiki iā ia ke hana paʻa i nā mahana kiʻekiʻe a kū i nā mahana a hiki i ka 1350 ℃. Eia kekahi, he conductivity thermal maikaʻi a me kahi ʻili laumania, e kōkua ana i ka hōʻemi ʻana i ke kūpaʻa o ka halihali a me ka hoʻohana ʻana i ka ikehu.
I ka ʻōlelo maʻalahi, ua hoʻolālā ʻia nā paipu keramika silicon carbide e hoʻoponopono i nā pilikia halihali o ka "wela, abrasive, a me ka corrosive". I ka halihali ʻana o ka slag a me ka mortar i nā ʻoihana e like me ka mining, metallurgy, a me ka mana thermal, hiki iā ia ke hoʻolōʻihi nui i ke ola lawelawe o nā pipelines a hōʻemi i ka downtime no ka hoʻololi; I ka halihali ʻana i nā media corrosive i nā ʻoihana kemika a me ka palekana o ke kaiapuni, hiki iā ia ke hōʻoia i ka hana paʻa lōʻihi a hōʻemi i ka pilikia o ka leakage. ʻOiai ʻoi aku ka kiʻekiʻe o ka hoʻopukapuka mua ʻana, he koʻikoʻi nā pono lōʻihi mai kahi hiʻohiʻona piha o ka hōʻemi ʻana i ka mālama ʻana, ka hoʻohaʻahaʻa ʻana i ka hoʻohana ʻana i ka ikehu, a me ka hōʻoia ʻana i ka hana ʻana.
He hana paʻakikī ka hana ʻana i nā paipu keramika silicon carbide. ʻO ka maʻamau, ua hui pū ʻia ka pauka silicon carbide me kahi liʻiliʻi o nā mea hoʻohui e hana i kahi "kino ʻōmaʻomaʻo" me kahi ikaika, a laila sintered i ka mahana kiʻekiʻe e hana i ka mea paʻakikī a paʻakikī. Wahi a nā pono like ʻole, e hoʻohana ʻia nā kaʻina hana like ʻole e like me ka reaction sintering a me ka pressureless sintering. No ka maʻalahi o ke kau ʻana, ua hoʻolako pinepine ʻia nā pipeline i hoʻopau ʻia me nā ʻāpana hoʻohui e like me nā flanges metala.
ʻOiai kona hana kiʻekiʻe loa, ʻo nā paipu keramika silicon carbide he mau mea keramika nō ia e pono ai ka "mālama mālie" i ka wā e hoʻohana ʻia ai. Pono e mālama pono ʻia ke kau ʻana a me ka halihali ʻana e pale aku i ka hopena paʻakikī; E hōʻoia i ke kākoʻo lawa a me ka uku hoʻonui wela e pale aku i nā ukana hou i hoʻokumu ʻia e ke kaumaha o waho a i ʻole nā loli mahana; Ma mua o ke koho ʻana i nā mea, ʻoi aku ka maikaʻi o ka loaʻa ʻana o kahi ʻenekinia loea e loiloi i ke ʻano kikoʻī, ka mahana, a me ke kaomi e loaʻa ai ka hopena kūpono loa.
Ma keʻano holoʻokoʻa, ua hoʻokō nā paipu keramika silicon carbide i ka mea kiʻekiʻe loa i ka "paʻakikī" a me ka "paʻa", e hāʻawi ana i nā hopena hilinaʻi no nā kūlana hoʻoili koi loa, a ʻo lākou nō nā "hero ʻike ʻole ʻia".
