ʻO Silicon Carbide Graphite Crucible: He Koho Kipi no nā ʻoihana wela kiʻekiʻe

I ka ʻoihana wela kiʻekiʻe o kēia wā,kiʻi kiʻi kiʻiʻoniʻoni kalaponaua lilo i mea nui ma muli o kona mau waiwai wela maikaʻi loa, ke kūpaʻa kemika a me ka ikaika kiʻekiʻe, a ua hoʻohana nui ʻia i ka hoʻoheheʻe metala, ka hana aniani, ka noiʻi ʻana a me nā ʻano ʻē aʻe. E ʻike kēia ʻatikala i nā hiʻohiʻona kūʻokoʻa, ka laulā noiʻi a me nā manaʻo hoʻomohala e hiki mai ana o nā crucibles graphite silicon carbide.

ʻO nā hiʻohiʻona o ka pahu graphite silika carbide
ʻO ka hui pū ʻana o ka silicon carbide (SiC) a me ka graphite e hāʻawi i ka crucible i nā waiwai maikaʻi loa o nā mea ʻelua. Hāʻawi kēia hui ʻana i nā crucibles silicon carbide graphite i kēia mau mea maikaʻi:

ʻOi aku ka maikaʻi o ka pale wela kiʻekiʻe: Hiki ke hana paʻa ka pahu silika carbide graphite i nā mahana ma mua o 1600 ° C me ka hoʻoheheʻe ʻole a me ka deformation.
ʻOi aku ka kiʻekiʻe o ka conductivity thermal ma mua o nā mea seramika maʻamau, e hōʻoia ana i ka hāʻawi ʻana i ka wela ma ka crucible a me ka hoʻomaikaʻi ʻana i ka pono hoʻomehana.
ʻO ke kūpaʻa kino kino ikaika: Hiki iā ia ke pale maikaʻi i ka corrosion o nā reagents kemika a hoʻonui i kona ola lawelawe.
ʻO ka ikaika mechanical maikaʻi loa: ʻO ka hui pū ʻana i ka paʻakikī o ka silicon carbide a me ka ikaika o ka graphite, hiki iā ia ke mālama i nā waiwai mechanical maikaʻi a hiki i nā wahi wela kiʻekiʻe.
Kūleʻa haʻalulu maikaʻi loa: ʻAʻole hiki iā lākou ke pohā i ka wā o ka hoʻomehana wikiwiki ʻana a i ʻole ka hoʻolili ʻana, e hoʻolilo iā lākou i mea kūpono no ka hoʻomehana wikiwiki a i ʻole ka hoʻoilo.
Nā wahi noi
ʻOi aku ka maikaʻi o nā crucibles graphite Silicon carbide i kekahi mau noi wela kiʻekiʻe, me:

Hoʻoheheʻe metala: Ma muli o kāna conductivity thermal maikaʻi loa a me ka pale ʻana i ka corrosion, hoʻohana nui ʻia ia i ka hoʻoheheʻe ʻana a me ka hoʻomaʻemaʻe ʻana o ka aluminika, ke keleawe, ke gula a me nā metala ʻē aʻe.
ʻO ka hana aniani: E hoʻolako i kahi kūlana wela kiʻekiʻe i ka wā o ke kaʻina hoʻoheheʻe aniani e hōʻoia i ka kūlike o ka hoʻoheheʻe ʻana a me ka hana ʻana.
Noiʻi Laboratory: ʻO nā ipu laʻana i hoʻohana mau ʻia i ka noiʻi ʻepekema waiwai a me nā hoʻokolohua wela kiʻekiʻe e hāʻawi i ka mana wela pololei.
ʻOihana Kemika: hoʻohana ʻia i loko o nā moku hoʻonā wela kiʻekiʻe a me nā moku no ka mālama ʻana i nā kemika corrosive a me nā reactants wela kiʻekiʻe.
Nā manaʻo hoʻomohala e hiki mai ana
Me ka hoʻomau mau ʻana o ka ʻenehana a me ka piʻi nui ʻana o ka noi i nā ʻoihana wela kiʻekiʻe, ʻo ka silicon carbide graphite crucibles he ākea noi. E kālele ana ka noiʻi a me ka hoʻomohala ʻana i ka wā e hiki mai ana i kēia mau ʻaoʻao:

Hoʻonui i nā mea waiwai: Nanotechnology a me nā mea noiʻi composite e hoʻonui hou i ka hana wela o ka crucible a me ka ikaika mechanical.
Hoʻoponopono i ke kumu kūʻai: E hoʻomaikaʻi i ke kaʻina hana, hoʻemi i nā kumukūʻai hana, hana i nā crucibles graphite silicon carbide i ʻoi aku ka maikaʻi, a hoʻonui i kā lākou noi noi.
Ka hoʻomaikaʻi ʻana i ke kaiapuni: E hoʻomohala i nā mea pili i ke kaiapuni e hōʻemi i ka hopena i ke kaiapuni a paipai i ka hoʻomohala ʻana i ka ʻenehana wela wela ʻōmaʻomaʻo.
i ka hopena
Ma ke ʻano he mea hana kiʻekiʻe, hana koʻikoʻi ka silicon carbide graphite crucible i ka ʻoihana wela kiʻekiʻe o kēia wā me kona kūpaʻa kiʻekiʻe kiʻekiʻe, conductivity thermal, corrosion resistance a me nā ʻano ʻē aʻe. Me ka holomua mau o ka ʻenehana a me ka hoʻonui ʻana i nā kahua noi, ʻoi aku ka nui o ka hana koʻikoʻi o ka silicon carbide graphite crucibles i ka ʻenehana wela kiʻekiʻe e hiki mai ana a hoʻoikaika i ka hana ʻoi aku ka maikaʻi a me ka hoʻonaninani ʻana i nā ʻoihana like ʻole.

Ma o ka ʻike hohonu a me ka hoʻohana ʻana i nā crucibles graphite silicon carbide, hiki ke hoʻokō ʻia nā holomua nui aʻe i ka hana wela kiʻekiʻe, ka hoʻokele ʻana i ka ʻenehana a me ka hoʻonui ʻana i ka ʻoihana.
