Ma ke kahua ʻoihana hou, ua ʻike ʻia nā keramika silicon carbide ʻo ia ka "pale kaua ʻoihana" a ua lilo i mea nui i nā wahi koʻikoʻi ma muli o ko lākou ikaika kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, a me ke kūpaʻa ʻana i ka pala. Akā ʻo ka mea i ʻike ʻole ʻia e ka poʻe he nui, he nui nā lālā o ka ʻohana keramika silicon carbide, a ʻo nā kaʻina hana hoʻomākaukau like ʻole e hāʻawi iā lākou i nā "ʻano pilikino" kū hoʻokahi. I kēia lā e kamaʻilio mākou e pili ana i nā ʻano maʻamau onā keramika silicon carbidea hōʻike i nā pono kūikawā o ka hopena sintered silicon carbide, ka ʻenehana koʻikoʻi o nā ʻoihana.
1, ʻO nā "kaikuaʻana ʻekolu" o nā keramika Silicon Carbide
ʻO ka hana o nā keramika silicon carbide e hilinaʻi nui ʻia i kāna kaʻina hana hoʻomākaukau. Aia i kēia manawa ʻekolu mau ʻano nui:
1. ʻAʻole kaomi ʻia ka silicon carbide sintered
Ma ka hoʻoheheʻe pololei ʻana i ka pauka silicon carbide ma o ka sintering wela kiʻekiʻe, he kiʻekiʻe kona density a me ka paʻakikī ikaika, akā kiʻekiʻe ka mahana hoʻomākaukau a he pipiʻi ke kumukūʻai, e kūpono ana no nā ʻāpana kikoʻī liʻiliʻi me nā koi hana kiʻekiʻe loa.
2. ʻO ka carbide silicon sintered i kaomi wela ʻia
I hana ʻia ma lalo o ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe, he ʻano paʻa kona a me ke kūpaʻa ʻana i ka ʻaʻahu maikaʻi loa, akā he paʻakikī a paʻakikī nā lako e hana i nā ʻāpana nui a paʻakikī paha, e kaupalena ana i kāna laulā noi.
3. Hana ʻia ka silicon carbide sintered (RBSiC)
Ma ka hoʻokomo ʻana i nā mea silicon i loko o nā mea maka silicon carbide a me ka hoʻohana ʻana i nā hopena kemika e hoʻopiha i nā hakahaka mea, haʻahaʻa ka mahana o ke kaʻina hana, pōkole ke kaʻina hana, a hiki ke hana maʻalahi ʻia nā ʻāpana nui a me nā ʻāpana ʻokoʻa. He mea kupaianaha ke kumukūʻai kūpono, e lilo ia i ʻano silicon carbide i hoʻohana nui ʻia ma ke kahua ʻoihana.
2, No ke aha i ʻoi aku ka makemake ʻia o ka silicon carbide sintered reaction?
Ma ke ʻano he huahana koʻikoʻi o ka ʻoihana, ʻo ke kaʻina hana kūikawā o ka hopena sintered silicon carbide (RBSiC) e hoʻolilo iā ia i "mea makemake nui ʻia" ma nā ʻoihana he nui. Hiki ke hōʻuluʻulu ʻia kona mau pono e nā huaʻōlelo koʻikoʻi ʻekolu:
1. Ikaika a paʻa
Hoʻokumu ke kaʻina hana sintering i kahi "ʻano hoʻopaʻa" i loko o ka mea, hiki ke kū i nā mahana kiʻekiʻe o 1350 ℃ a he kūpaʻa maikaʻi loa ia i ka ʻaʻahu a me ke kūpaʻa wela kiʻekiʻe - ʻaʻole i hōʻino maʻalahi i nā wahi ʻaʻahu kiʻekiʻe a me nā mahana kiʻekiʻe, kūpono loa no nā hiʻohiʻona wela kiʻekiʻe e like me nā mea pono o ka umu a me nā mea puhi.
2. E hele i ke kaua me nā lako māmā
Ke hoʻohālikelike ʻia me nā mea metala kuʻuna, ʻoi aku ka haʻahaʻa o ka nui o ka silicon carbide sintered reaction akā hiki ke hāʻawi i ka pae like o ka ikaika, e hōʻemi nui ana i ka hoʻohana ʻana i ka ikehu o nā lako. No ka laʻana, i ka ʻoihana photovoltaic, hiki i nā ʻāpana silicon carbide māmā ke hoʻomaikaʻi nui i ka pono hana o nā umu kristal hoʻokahi.
3. Hiki ke loli a me ka maʻalahi
Inā paha he mau pā semiconductor me ke anawaena o 2 mika, nā nozzles paʻakikī, nā apo sila, a i ʻole nā ʻāpana i hoʻopilikino ʻia me nā ʻano like ʻole, hiki i ka ʻenehana sintering hopena ke hoʻomalu pololei i ke ʻano a me ka nui, e hoʻoponopono ana i ka pilikia hana o "nui a pololei".
3. ʻO ka 'mana hoʻokele ʻike ʻole' o ka hoʻonui ʻana i ka ʻoihana
Ua komo ke "kiʻi" o ka silicon carbide sintered reaction i loko o nā ʻano like ʻole, mai nā ala alakaʻi kū i ka erosion i loko o nā umu metallurgical a hiki i nā pipeline kū i ka corrosion i nā lako kemika. ʻAʻole wale kona ola ʻana e hoʻolōʻihi i ke ola o nā lako, akā kōkua pū kekahi i nā ʻoihana e hoʻokō i ka mālama ʻana i ka ikehu a me ka hoʻemi ʻana i ka hoʻohana ʻana - no ka laʻana, ma ke kahua o nā umu ʻoihana, hiki i ka hoʻohana ʻana i nā lako umu silicon carbide ke hōʻemi nui i ka pohō wela.
Hopena
ʻOi aku ka 'hiki' o nā keramika carbide ma mua o kēia. Ma ke ʻano he paionia i ka ʻenehana sintering reaction, hoʻomau mākou i ka hoʻomaikaʻi ʻana i ke kaʻina hana e hoʻonui i ka waiwai o kēia mea i nā wahi koʻikoʻi. Inā ʻoe e ʻimi nei i nā hopena ʻoihana e kū i ka wela, kū i ka hopena, a he lōʻihi ke ola, makemake paha ʻoe e hoʻolohe i nā mea hou aʻe e hiki ai ke hana i nā keramika silicon carbide!
Ua kālele ʻo Shandong Zhongpeng i ka noiʻi a me ka hana ʻana o ka silicon carbide sintered no nā makahiki he ʻumi a ʻoi, e hāʻawi ana i nā hoʻonā seramika i hana ʻia no nā mea kūʻai aku honua.
