ʻO ka lining ʻaʻahu kūpaʻa Silicon carbide: he pale ikaika no nā mea hana ʻoihana

I nā hanana ʻoihana he nui, pono pinepine nā mea hana i nā ʻano hana koʻikoʻi like ʻole, a me nā pilikia ʻaʻahu a me nā waimaka e hoʻopilikia koʻikoʻi i ke ola lawelawe a me ka hana pono o nā mea hana. ʻO ka puka ʻana mai o ka lining kūpaʻa silicon carbide e hāʻawi i kahi hopena kūpono i kēia mau pilikia, a ke lilo mālie nei ia i pale ikaika no nā mea hana ʻoihana.
Silicon carbide, he pūhui i haku ʻia me ke kalapona a me ke silika, he mau mea kupanaha. He kiʻekiʻe loa kona paʻakikī, ʻelua wale nō i ka daimana paʻakikī loa ma ke ʻano, a ʻo kona paʻakikī Mohs ka lua ma mua o ke daimana, ʻo ia hoʻi hiki iā ia ke pale maʻalahi i ka ʻoki ʻana a me ka ʻoki ʻana i nā ʻāpana paʻakikī like ʻole a hana maikaʻi i ka pale ʻana. I ka manawa like, he haʻahaʻa haʻahaʻa haʻahaʻa ka silicon carbide, hiki iā ia ke hoʻomalu i ka lole lole ma kahi haʻahaʻa haʻahaʻa ma lalo o nā kūlana paʻakikī e like me ka friction maloʻo a i ʻole ka lubrication maikaʻi ʻole, e hoʻolōʻihi i ke ola lawelawe o nā lako.
Ma waho aʻe o ka paʻakikī a me ka haʻahaʻa haʻahaʻa haʻahaʻa, paʻa loa nā waiwai kemika o ka carbide silika, me ka inertness kemika maikaʻi loa. Loaʻa iā ia ke kūpaʻa ikaika i ka corrosion mai nā ʻakika ikaika (koe wale ka hydrofluoric acid a me ka waika phosphoric concentrated), nā kumu ikaika, nā paʻakai hoʻoheheʻe ʻia, a me nā metala hoʻoheheʻe like ʻole (e like me ke alumini, zinc, keleawe). ʻO kēia hiʻohiʻona hiki iā ia ke hana paʻa a hiki i nā wahi paʻakikī kahi e noho pū ai ka media corrosive a me ka lole.
Mai ka hiʻohiʻona o nā waiwai wela a me ke kino, hōʻike pū ka silicon carbide i ka hana maikaʻi loa. He kiʻekiʻe ka thermal conductivity a hiki ke hoʻopau maikaʻi i ka wela i hana ʻia e ka friction, e pale aku i ka palupalu a i ʻole ka hoʻoheheʻe ʻana o ke kaumaha ma muli o ka wela nui o nā mea hana, a me ka mālama ʻana i ke kūpaʻa maikaʻi; ʻO kona coefficient o ka hoʻonui wela he haʻahaʻa, hiki ke hōʻoia i ka paʻa o ka dimensional o nā mea hana a hoʻemi i ka pōʻino o ke koʻikoʻi wela i nā mea hana i ka wā o ka piʻi ʻana o ka mahana. Eia kekahi, ʻoi aku ka maikaʻi o ke kūpaʻa wela kiʻekiʻe o ka silicon carbide, me kahi mahana hoʻohana a hiki i 1350 ° C i ka ea (oxidizing environment) a ʻoi aku ka kiʻekiʻe i ka inert a i ʻole ka hōʻemi ʻana i nā kaiapuni.

Ma muli o nā hiʻohiʻona i luna aʻe, ua hoʻohana nui ʻia ka lining silicon carbide wear-resistant i nā ʻoihana he nui. I ka ʻoihana mana, holoi pinepine ʻia nā paipu i hoʻohana ʻia no ka lawe ʻana i nā mea e like me ka lehu lele e nā ʻāpana paʻa holo wikiwiki, a pau koke nā pipeline maʻamau. Eia nō naʻe, ma hope o ka hoʻohana ʻana i ka lining pale silicon carbide, ʻoi aku ka maikaʻi o ka pale ʻana o ka pipeline, a hoʻonui nui ʻia ke ola lawelawe; I loko o ka ʻoihana mining, ʻo ka hoʻokomo ʻana o ka silicon carbide lole pale pale ma nā ʻāpana ʻaʻahu e like me ka slurry conveying pipelines a me ka crusher interiors e hōʻemi i ka pinepine o ka mālama pono ʻana a hoʻomaikaʻi i ka hana hana; I ka ʻoihana kemika, e kū ana i ka corrosive media a me ka paʻakikī o ka hopena kemika, silicon carbide wear-resistant lining ʻaʻole ia wale nō ke ʻaʻahu, akā ke pale maikaʻi hoʻi i ka corrosion kemika, e hōʻoiaʻiʻo ana i ka hana palekana a paʻa o nā mea hana.
ʻO ka pōkole, hāʻawi ka lining silicon carbide i ka pale pono no nā mea hana ʻoihana me kāna hana maikaʻi loa. Me ka hoʻomau mau ʻana o ka ʻepekema waiwai, e hoʻomau ʻia ka hoʻokō ʻana o ka silicon carbide wear-resistant lining, a e hoʻemi hou ʻia ke kumukūʻai. I ka wā e hiki mai ana, ua manaʻo ʻia e hoʻohana ʻia i nā kula hou aʻe a pāʻani i kahi kuleana nui i ka hana kūpono a paʻa o ka hana ʻoihana.
