Nā Papa Uila Silicon Carbide: Ke Koho Kūpono no nā ʻOihana Wela Kiʻekiʻe, e Mālama ana i kāu Hana ʻana

Ma ke kahua ākea o ka hana ʻoihana wela kiʻekiʻe, nā papa umu, ma ke ʻano he mau ʻāpana koʻikoʻi e lawe ana i nā mea no ka hana ʻana i ka wela kiʻekiʻe, pili pololei kā lākou hana i ka pono o ka hana ʻana, ka maikaʻi o ka huahana, a me nā kumukūʻai hana. Eia nō naʻe, ke kū nei nā papa umu kuʻuna i nā ʻano ʻino e like me nā mahana kiʻekiʻe mau, nā haʻalulu wela pinepine, ka ʻaʻahu ʻana i nā mea, a me ka pala kemika, pinepine lākou e hālāwai me nā pilikia e like me ke ola lawelawe pōkole, ka deformation a me ka haki ʻana, a me nā kumukūʻai mālama kiʻekiʻe, kahi e kaupalena nui ai i ka hana paʻa o ka hana ʻana. ʻO ka puka ʻana mai o nā papa umu silicon carbide, me ko lākou mau pono hana maikaʻi loa, ua lawe mai i kahi holomua kipi i ka hana ʻoihana wela kiʻekiʻe.

Nā Pōmaikaʻi Koʻikoʻi o nā Papa Kiln Silicon Carbide

Hiki i nā papa umu ʻaila Silicon carbide ke lilo i mea punahele hou i nā ʻoihana wela kiʻekiʻe ma muli o nā pono he nui i hāʻawi ʻia e ko lākou mau waiwai kūikawā:
ʻOi aku ka maikaʻi o ke kūpaʻa wela kiʻekiʻe: Loaʻa i ka mea silicone carbide kahi kiko heheʻe kiʻekiʻe loa, e hiki ai i nā papa umu silicon carbide ke kū maʻalahi i nā wahi wela kiʻekiʻe ma luna o 1600°C. Hana paʻa lākou i ka wā o nā hana wela kiʻekiʻe lōʻihi a ʻaʻole e palupalu, hoʻololi, a i ʻole nā ​​​​pilikia ʻē aʻe ma muli o nā mahana kiʻekiʻe, e hōʻoiaʻiʻo ana i ka like a me ke kūpaʻa o ke kaʻina hana hoʻomehana mea i loko o ka umu.

Ke kūpaʻa maikaʻi loa i ka hoʻohana ʻana:He paʻakikī loa ka Silicon carbide, a ʻoi aku ka maikaʻi o kona kūpaʻa i ka ʻaʻahu ʻana ma mua o nā papa umu kuʻuna i hana ʻia me ka lepo, ka alumini kiʻekiʻe, a me nā mea ʻē aʻe. I ka wā e hoʻouka ai a me ka neʻe ʻana o nā mea, hiki i nā papa umu silicon carbide ke pale pono i ka friction a me ka hopena o nā mea, e hōʻemi i ka ʻaʻahu ʻana o ka ʻili, a laila e mālama ana i ka palahalaha maikaʻi a me ka hōʻoia ʻana i ka hoʻomehana like ʻana o nā mea.

Ke kū'ē kū'ē wela kūikawā:I ka hana ʻoihana wela kiʻekiʻe, hana pinepine nā papa umu i nā kaʻina hana hoʻomehana a hoʻoluʻu wikiwiki, kahi e kau ai i nā koi kiʻekiʻe loa i ko lākou kūpaʻa haʻalulu wela. He haʻahaʻa loa ka coefficient o ka hoʻonui linear a me ka conductivity thermal maikaʻi loa o nā papa umu Silicon carbide, hiki ke pale pono i ke kaumaha thermal i hoʻokumu ʻia e nā loli wela koke a hōʻemi nui i ka hanana o ka haki, spalling, a me nā hanana ʻē aʻe.

Ola Hana Lōʻihi Loa:Mahalo i nā waiwai maikaʻi loa i luna, ʻoi aku ka lōʻihi o ke ola lawelawe o nā papa umu silicon carbide ma mua o nā papa umu kuʻuna. Ma lalo o nā kūlana hana like, hiki i ko lākou ola lawelawe ke 3-5 mau manawa lōʻihi a ʻoi aku paha ma mua o nā papa umu kuʻuna, e hōʻemi nui ana i ke alapine o ka hoʻololi ʻana i ka papa umu a me nā pohō hana a me nā kumukūʻai hana i hoʻokumu ʻia e nā pani no ka hoʻololi ʻana.

Paʻa Kemika Maikaʻi:He kūpaʻa ikaika ka mea silicone carbide i nā mea ʻino e like me nā waikawa a me nā alkalis. I loko o kekahi mau umu wela kiʻekiʻe e loaʻa ana nā kinoea ʻino a i ʻole nā ​​​​mea, hiki iā ia ke mālama i nā waiwai kemika paʻa a ʻaʻole maʻalahi e hōʻino ʻia e nā hopena kemika, e hōʻoia hou ana i ka hana paʻa o ka umu.

ʻO ka hana maikaʻi loa o nā papa umu silicon carbide i hiki ai iā lākou ke hoʻohana nui ʻia ma nā kahua ʻoihana wela kiʻekiʻe he nui.Ma ka ʻoihana keramika, inā paha he puhi ʻana i nā keramika o kēlā me kēia lā, nā keramika kuhikuhipuʻuone, a i ʻole nā ​​​​keramika kūikawā, hiki i nā papa umu silicon carbide ke kū i ke kaiapuni ʻino o nā umu wela kiʻekiʻe, e hōʻoia i ka hoʻomehana like ʻana o nā blanks keramika i ka wā o ke ahi ʻana, a hoʻomaikaʻi i nā helu hōʻoia huahana.Ma ka ʻoihana metallurgical, hiki ke hoʻohana ʻia i nā loulou hana wela kiʻekiʻe e like me ka sintering a me ka hoʻoheheʻe ʻana i nā mea metala, e pale ana i ka ʻino ʻana o ka metala hoʻoheheʻe a me ka slag.Ma ka ʻoihana uila, no ka hoʻomākaukau ʻana i ka mahana kiʻekiʻe o nā huahana kikoʻī e like me nā keramika uila a me nā mea semiconductor, hiki i ke kūpaʻa a me ka maʻemaʻe o nā papa umu silicon carbide ke hoʻokō i nā koi hana koʻikoʻi. Eia kekahi, he kuleana koʻikoʻi ko nā papa umu silicon carbide i ka hana wela kiʻekiʻe i nā ʻoihana e like me ke aniani a me nā mea refractory.
