ʻO ka uhi pale ʻaʻahu Silicon carbide: he pale paʻa no nā lako ʻoihana

I nā hiʻohiʻona ʻoihana he nui, pono pinepine nā lako e hoʻoponopono i nā ʻano hana ʻino like ʻole, a ʻo nā pilikia o ke komo ʻana a me ka haehae e hoʻopilikia nui i ke ola lawelawe a me ka pono hana o nā lako. ʻO ka puka ʻana mai o ka lining pale ʻaʻahu silicon carbide e hāʻawi i kahi hopena kūpono i kēia mau pilikia, a ke lilo mālie nei ia i pale paʻa no nā lako ʻoihana.
Karbida silika, he hui i haku ʻia me ke kalapona a me ka silicon, he mau waiwai kupaianaha. He kiʻekiʻe loa kona paʻakikī, ʻo ka lua wale nō i ka daimana paʻakikī loa ma ke ʻano, a ʻo kona paʻakikī Mohs ka lua wale nō i ka daimana, ʻo ia hoʻi hiki iā ia ke pale maʻalahi i ke kahakaha ʻana a me ka ʻoki ʻana o nā ʻāpana paʻakikī like ʻole a hana maikaʻi i ke kūʻē ʻana i ka ʻaʻahu. I ka manawa like, he haʻahaʻa hoʻi ka coefficient o ka friction o ka silicon carbide, hiki ke kaohi i ka helu ʻaʻahu ma kahi pae haʻahaʻa loa ma lalo o nā kūlana paʻakikī e like me ka friction maloʻo a i ʻole ka lubrication maikaʻi ʻole, e hoʻolōʻihi nui ana i ke ola lawelawe o nā lako.
Ma waho aʻe o ka paʻakikī a me ke koina haʻalulu haʻahaʻa, paʻa loa nā waiwai kemika o ka silicon carbide, me ka inertness kemika maikaʻi loa. Loaʻa iā ia ke kūpaʻa ikaika i ka palaho mai nā waikawa ikaika (koe wale nō ka waikawa hydrofluoric a me ka waikawa phosphoric i hoʻohuihui ʻia), nā kumu ikaika, nā paʻakai hoʻoheheʻe ʻia, a me nā metala hoʻoheheʻe like ʻole (e like me ka alumini, zinc, keleawe). ʻO kēia ʻano e hiki ai iā ia ke hana paʻa a hiki i nā wahi ʻino kahi e noho pū ai nā mea corrosive a me ke kapa komo.
Mai ka manaʻo o nā waiwai wela a me ke kino, hōʻike pū ka silicon carbide i ka hana maikaʻi loa. Loaʻa iā ia kahi conductivity wela kiʻekiʻe a hiki ke hoʻokuʻu pono i ka wela i hana ʻia e ka friction, e pale ana i ka palupalu o nā mea a i ʻole ka haki ʻana o ke kaumaha wela i hoʻokumu ʻia e ka wela wela o nā lako, a mālama i ke kūpaʻa maikaʻi; He haʻahaʻa iki kona coefficient o ka hoʻonui ʻana o ka wela, hiki ke hōʻoia i ka paʻa o ka dimensional o nā lako a hōʻemi i ka pōʻino o ke kaumaha wela i nā lako i ka wā o nā loli o ka mahana. Eia kekahi, he mea kupaianaha nō hoʻi ke kūpaʻa wela kiʻekiʻe o ka silicon carbide, me ka mahana hoʻohana a hiki i ka 1350 ° C i ka lewa (kaiapuni oxidizing) a ʻoi aku ka kiʻekiʻe ma nā wahi inert a i ʻole ka hoʻemi ʻana.

Ma muli o nā ʻano i luna, ua hoʻohana nui ʻia ka uhi pale ʻaʻahu silicon carbide ma nā ʻoihana he nui. I ka ʻoihana mana, holoi pinepine ʻia nā pipeline i hoʻohana ʻia no ka lawe ʻana i nā mea e like me ka lehu lele e nā ʻāpana paʻa e kahe wikiwiki ana, a pau koke nā pipeline mea maʻamau. Eia nō naʻe, ma hope o ka hoʻohana ʻana i ka uhi pale ʻaʻahu silicon carbide, ua hoʻomaikaʻi nui ʻia ke kūpaʻa ʻaʻahu o ka pipeline, a ua hoʻolōʻihi nui ʻia ke ola lawelawe; I ka ʻoihana mining, ʻo ke kau ʻana o ka uhi pale ʻaʻahu silicon carbide ma nā ʻāpana pale ʻaʻahu e like me nā pipeline lawe slurry a me nā loko crusher e hōʻemi ana i ka pinepine o ka mālama ʻana i nā lako a hoʻomaikaʻi i ka pono hana; I ka ʻoihana kemika, e kū nei i nā media corrosive a me nā wahi hana kemika paʻakikī, ʻaʻole wale ka uhi pale ʻaʻahu silicon carbide, akā pale maikaʻi hoʻi i ka corrosion kemika, e hōʻoiaʻiʻo ana i ka hana palekana a paʻa o nā lako.
I ka pōkole, hāʻawi ka uhi pale ʻaʻahu silicon carbide i ka palekana hilinaʻi no nā lako ʻoihana me kāna hana maikaʻi loa. Me ka hoʻomohala mau ʻana o ka ʻepekema mea, e hoʻomau ʻia ka hoʻomaikaʻi ʻana i ka hana o ka uhi pale ʻaʻahu silicon carbide, a e hoʻemi hou ʻia ke kumukūʻai. I ka wā e hiki mai ana, manaʻo ʻia e hoʻohana ʻia ma nā kahua hou aʻe a pāʻani i kahi hana nui i ka hana pono a paʻa o ka hana ʻoihana.
