E ʻike i ke kūlana kiʻekiʻe o nā pōhaku lepo Silicon Carbide no kāu mau pono ʻoihana

I loko o ke aupuni o ka ʻoihana hou, kahi o nā hana kiʻekiʻe - wela ka mea maʻamau, ʻo ke koho ʻana i nā mea refractory hiki ke hoʻololi nui i ka pono, ka lōʻihi, a me ke kumu kūʻai o nā kaʻina hana. Ua puka mai nā pōhaku lepo Silicon carbide ma ke ʻano he hopena alakaʻi, e hāʻawi ana i kahi hui kūʻokoʻa o nā waiwai e pono ai lākou i nā ʻano noi.

Na Mea Kino a me Kinohi Kūikawā

Paʻa kiʻekiʻe a me ka pale ʻana i ka abrasion

Ke kaena nei nā pōhaku lepo silikoni i ka paʻakikī Mohs o 9, kahi kokoke i kahi daimana. ʻO kēia paʻakikī kiʻekiʻe e hiki ai iā lākou ke kū i ka abrasion koʻikoʻi mai nā ʻāpana kiʻekiʻe, nā mea hoʻoheheʻe ʻia, a me ka holoi ʻana i nā mīkini. I loko o nā ʻoihana e like me ka mining, metallurgy, a me ka hana sima, kahi e ʻike mau ai nā mea hana i nā mea abrasive, hiki i ka hoʻohana ʻana i ka silicon carbide bricks ke hoʻonui nui i ke ola lawelawe o nā linings umu, ducts, a me nā mea koʻikoʻi ʻē aʻe. No ka laʻana, i loko o nā kiln sima, ʻo ke ʻano abrasive o nā mea maka a me ke kiʻekiʻe - wela kaiapuni hiki ke hoʻopau wikiwiki i nā mea refractory kuʻuna. Hiki i nā pōhaku lepo Silicon carbide, me ko lākou kūpaʻa abrasion koʻikoʻi, hiki ke hoʻomanawanui i kēia mau kūlana paʻakikī, e hōʻemi ana i ka pinepine o ka mālama ʻana a me ka hoʻololi ʻana, a me ka hoʻohaʻahaʻa ʻana i nā kumukūʻai hana.

Kūlana Thermal Conductivity

ʻO kekahi o nā hiʻohiʻona koʻikoʻi o nā pōhaku silika carbide ko lākou kiʻekiʻe thermal conductivity. Hāʻawi kēia waiwai i ka hoʻoili wela kūpono i loko o nā umu ahi a me nā reactors. Ma nā noi kahi e koi ʻia ai ka hoʻomehana wikiwiki a me ka hoʻoilo ʻana, e like me ke kaʻina hana semiconductor no ka annealing a me ka sintering, hiki i nā pōhaku silika carbide ke hoʻololi koke i ka wela i ka mea hana, e hōʻoiaʻiʻo ana i ka hāʻawi ʻana i ka wela. ʻO ka hopena, ʻoi aku ka maikaʻi o ke kaʻina hana, a ʻoi aku ka maikaʻi o ka huahana hope. Eia kekahi, ʻo ka conductivity thermal kiʻekiʻe o nā pōhaku silika carbide e kōkua pū i ka hoʻemi ʻana i ka ikehu. Ma ka ʻae ʻana i ka hoʻoili wela ʻoi aku ka wikiwiki, ʻoi aku ka liʻiliʻi o ka ikehu ma ke ʻano o ka wela, e alakaʻi ana i ka mālama nui ʻana i nā kumukūʻai ikehu i ka manawa.​

ʻO ke kūpaʻa wela maikaʻi loa

Hiki i nā brick carbide silikon ke mālama i ko lākou kūlana kūpono a me nā waiwai mechanical i nā wela kiʻekiʻe loa, a hiki i 1800 ° C (3272 ° F) i kekahi mau hihia. ʻO kēia kūpaʻa wela ʻokoʻa e kūpono iā lākou no ka hoʻohana ʻana i nā umu wela wela, e like me nā mea i hoʻohana ʻia i ka hana ʻana i ke kila, nā metala non-ferrous, a me ke aniani. I loko o kahi kapuahi hana kila, no ka laʻana, pono ke pale i ka wela nui o ke kila hoʻoheheʻe ʻia a me ke kaʻa kaʻa wela mau i ka wā o ke kaʻina hana. Hiki i nā pōhaku silika carbide ke hoʻomanawanui i kēia mau kūlana me ka ʻole o ka deformation nui a i ʻole degradation, e hāʻawi ana i ka palekana hilinaʻi no ka pūpū umu a me ka hōʻoia ʻana i nā hana hana maʻemaʻe.​

Kūleʻa Kemika Kiʻekiʻe

Hōʻike kēia mau pōhaku lepo i ke kūpaʻa maikaʻi loa i nā mea ʻawaʻawa a me nā mea alkaline. I nā ʻoihana kemika, kahi e hoʻohana nui ʻia ai nā kemika corrosive, hiki ke hoʻohana ʻia nā pōhaku silicon carbide e laina i nā reactors, nā pahu mālama, a me nā paipu. Hiki iā lākou ke pale maikaʻi i ka corrosion o nā ʻakika like ʻole, alkalis, a me nā paʻakai, e pale ana i nā leaks a hōʻoia i ka hana palekana o nā mea hana. No ka laʻana, i ka hana ʻana i nā mea kanu, kahi e komo ai nā waikawa ikaika a me nā alkalis i ka hana hana, hāʻawi nā pōhaku silicon carbide i ka pale mau loa i ka ʻino kino, e hōʻemi ana i ka hopena o ka hemahema o ka lako a me ka pollution kaiapuni.​

Nā noi like ʻole ma nā ʻoihana lehulehu

1. ʻOihana Metallurgical

Hana kila:Ma ke kaʻina hana kila, hoʻohana ʻia nā pōhaku lepo silicon carbide i nā kapuahi uila, nā ladles, a me nā tundishes. ʻO kā lākou kiʻekiʻe thermal conductivity kōkua i ka hoʻomehana wikiwiki a me ka hoʻoheheʻe ʻana i ke kila, ʻoiai ʻo kā lākou kūpaʻa maikaʻi loa i ke kila hoʻoheheʻe a me ka palaka e hōʻoia i ka lōʻihi o ka uhi ʻana o ka umu. ʻAʻole kēia e hoʻomaikaʻi wale i ka maikaʻi o ka hana kila akā e hōʻemi hoʻi i ka pono o ka relining pinepine, he hana hoʻopau manawa a me ke kumu kūʻai.​

ʻO ka hoʻoheheʻe metala ʻole:No ka hoʻoheheʻe ʻana i nā metala e like me ke aluminika, ke keleawe, a me ka zinc, hoʻohana nui ʻia nā pōhaku silika carbide. I ka hoʻoheheʻe alumini, no ka laʻana, hoʻohana ʻia nā pōhaku lepo i nā cell electrolytic a me ka paʻa ʻana i nā umu. ʻO ko lākou kū'ēʻana i nā hopenaʻino o ka alumini hoʻoheheʻe a me kona mau paʻakai pili, me ko lākou kūpaʻa wela kiʻekiʻe, e lilo lākou i mea koho maikaʻi loa no ka mālamaʻana i ka pono o nā mea hoʻoheheʻeʻia a me ka hōʻoiaʻana i ka hana mau.

2. ʻOihana Ceramic a Glass

Hana ʻia ʻo Ceramic:I loko o nā kiln seramika, hoʻohana ʻia nā pōhaku lepo silicon carbide e like me nā lako kiln, me nā papa, nā kākoʻo, a me nā saggers. ʻO ko lākou ikaika kiʻekiʻe i nā mahana kiʻekiʻe e hiki ai iā lākou ke amo i ke kaumaha o nā huahana seramika i ka wā o ke puhi ʻana, ʻoiai kā lākou conductivity thermal maikaʻi e hōʻoia i ka hoʻomehana like ʻana o nā seramika. Loaʻa kēia i nā huahana keramika kiʻekiʻe me ka waihoʻoluʻu a me ke ʻano. Eia kekahi, ʻo ka lōʻihi o ka lawelawe ʻana o nā lako kiln silicon carbide e hōʻemi i ke kumukūʻai o ka hoʻololi ʻana a me ka downtime i ka hana ceramic.

Hana aniani:I loko o nā kapuahi aniani, hoʻohana ʻia nā pōhaku lepo silicon carbide i nā wahi i loaʻa nā wahi kiʻekiʻe - wela a me nā pōʻino ʻino, e like me ke keʻena kuni a me ke aniani hoʻoheheʻe. Hiki iā lākou ke kū i ke aniani hoʻoheheʻe kiʻekiʻe a me ka hana corrosive o ke aniani - hoʻokumu i nā kinikona, e hāʻawi ana i ka insulation hilinaʻi a me ka pale no ka hale umu. Kōkua kēia i ka hoʻomaikaʻi ʻana i ka hoʻoheheʻe aniani a me ka maikaʻi o ke aniani i hana ʻia
ʻO ka hana mana a me ka ʻōpala ʻōpala.

Nā mea kanu mana:I loko o nā mea kanu mana ahi, hoʻohana ʻia nā pōhaku lepo silicon carbide i loko o nā paila a me nā ʻōnaehana lawelawe lehu. Hiki iā lākou ke pale aku i ka abrasion o ka lehu lele a me ke kaiapuni wela wela, hoʻonui i ka hilinaʻi a me ka pono o nā mea hana mana. Eia kekahi, i nā mea kanu mana biomass, kahi i hoʻopau ʻia ai ka biomass i nā kinoea corrosive a me ka lehu, hāʻawi nā pōhaku silika carbide i ke kūpaʻa maikaʻi loa i kēia mau kūlana paʻakikī, e hōʻoia ana i ka hana paʻa o ka mana.​

Nā mea kanu ʻōpala:ʻO ka hoʻopau ʻana i ka ʻōpala e pili ana i ka puhi wela kiʻekiʻe o nā mea ʻōpala like ʻole, hiki ke hana i nā kinoea a me ka lehu. Hoʻohana ʻia nā pōhaku silika carbide i ka uhi ʻana o nā incinerators e kū i kēia mau kūlana koʻikoʻi. ʻO ko lākou kūpaʻa kemika e pale i nā paia incinerator mai ka ʻinoʻino, ʻoiai ʻo ko lākou kūlana kiʻekiʻe-mehana e hōʻoia i ka hana palekana a maikaʻi hoʻi o ke kaʻina hana ʻōpala.​
