Ma keʻano he hui kūikawā i ka hanaʻana oʻAiʻa Silicon Carbide(silica carbide crucible), aloha ʻia kā mākou huahana e nā mea kūʻai aku ʻoihana no kā lākou hana ʻoi aku ka maikaʻi a me ka hilinaʻi. I kēia lā, hāʻawi mākou iā ʻoe i kahi loiloi piha o nā pono o nā crucibles silicon a haʻi iā ʻoe i ke kumu e lilo ai kā mākou crucible i koho naʻauao no kāu hana wela kiʻekiʻe.
He aha ka Silicon Carbide Crucible?
ʻO Silicon Carbide Crucible kahi pahu hana kiʻekiʻe i hana ʻia me ka silicon carbide (SiC) ma ke ʻano he kumu kumu. ʻO kāna mau hiʻohiʻona nui:
ʻO ka conductivity thermal kiʻekiʻe: ʻoi aku ka maikaʻi o ka carbide silicon, hiki ke hoʻololi koke i ka wela a hoʻomaikaʻi i ka hoʻoheheʻe ʻana.
Kūleʻa wela kiʻekiʻe: hiki ke pale i nā wela wela a hiki i 1600 ° C a i ʻole ke kiʻekiʻe, kūpono no nā ʻano hana wela kiʻekiʻe.
ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion: Ke kūpaʻa ikaika i ka ʻakika, ka alkali a me ka hoʻoheheʻe metala, e hoʻolōʻihi i ke ola o ka huahana.
ʻO ka ikaika kiʻekiʻe: ʻOiai ma nā wela kiʻekiʻe hiki ke mālama i nā waiwai mechanical maikaʻi loa, ʻaʻole maʻalahi ka haki ʻana a i ʻole deformation.
Ke ola lawelawe lōʻihi: E hoʻohana i ke kūpaʻa a me ka hana maikaʻi loa ma hope o ka hoʻohana pinepine ʻana.
No ke aha e koho ai i kā mākou silika carbide graphite crucible?
1. Ke koho koʻikoʻi o nā mea waiwai kiʻekiʻe
Hoʻohana mākou i ka silicon carbide kiʻekiʻe-maʻemaʻe (SiC) a me ka graphite i hui pū ʻia me nā mea hoʻopaʻa paʻa kiʻekiʻe, ma o ka hoʻohālikelike ʻepekema, e hōʻoia i ka crucible i ka conductivity thermal maikaʻi loa, ka pale ʻana i ka mahana a me ke kūpaʻa oxidation.
2. ʻenehana hana nani
Hoʻohana kā mākou crucible i ke kaʻina hana Isostatic Pressing e hōʻoia i ke kiʻekiʻe kiʻekiʻe a me ke kūlike o ka huahana, e hoʻemi i ke kaumaha o loko, a e hoʻoikaika i ka hopena o ka hopena. I ka manawa like, hoʻomaikaʻi hou ʻia ka ikaika a me ka lōʻihi o ka crucible ma o ke kaʻina hana Sintering kiʻekiʻe (i kekahi manawa Sintering).
3. ʻOi aku ka maikaʻi o ka hoʻoiho wela
Hoʻohālikelike ʻia me ka graphite crucible kuʻuna, ʻo kā mākou silicon carbide crucible he 17% ka wikiwiki o ka hoʻololi ʻana i ka wela, e hōʻemi nui ana i ka manawa hoʻoheheʻe a me ka hoʻomaikaʻi ʻana i ka hana hana.
4. Kūleʻa maikaʻi i ka corrosion
No ka corrosion o ka aluminika, ke keleawe, ke gula a me nā wai hoʻoheheʻe ʻē aʻe, kā mākou crucible ma hope o ka hoʻomaʻamaʻa kūikawā, ʻoi aku ka ʻoi aku o ka corrosion o ka ʻili, kūpono no ka hoʻohana ʻana i ka wā lōʻihi.
5. Ke ola lawelawe lōʻihi
Ma nā hoʻokolohua hoʻokolohua a me nā manaʻo o nā mea kūʻai aku maoli, ua hōʻike kā mākou crucibles i ka piʻi ʻana o 20% + i ke ola lawelawe ma nā wela kiʻekiʻe, ʻoi aku hoʻi i ka hana hou.
6. Nā hāʻina hoʻoponopono
Hiki iā mākou ke hana i nā lawelawe crucible e like me nā pono kikoʻī o kā mākou mea kūʻai aku, me ke ʻano, ka nui a me nā koi hana kūikawā, e hōʻoia i ka hoʻokō ʻia ʻana o nā hiʻohiʻona noiʻi paʻakikī.
Hoʻohana ʻia ke ʻano okiʻi kilikakika graphite
Hoʻohana nui ʻia kā mākou silicon carbide crucible i nā kahua aʻe:
ʻO ka hoʻoheheʻe ʻana i ka metala: ʻO ka hoʻoheheʻe ʻana i ka aluminika, ke keleawe, ke gula, ke kālā a me nā metala ʻē aʻe.
Ka hana aniani: ʻO nā ipu kūpono i loko o nā umu aniani wela wela.
Hoʻohana ʻia no ka hoʻoheheʻe ʻana i ka wela kiʻekiʻe o ka lawe ʻana i nā seramika a me nā mea refractory.
Laboratory kiʻekiʻe wela hoʻokolohua: e hoʻolako i ka paʻa a hilinaʻi kiʻekiʻe wela kaiapuni.
Inā ʻoe e hana nei i ka hana metala, ka hana aniani a i ʻole nā hoʻokolohua noiʻi ʻepekema, hiki i kā mākou huahana ke lawe mai i ke kākoʻo kūpono a paʻa no kāu hana.
No ke aha e koho ai iā mākou ma mua o nā hōʻailona ʻē aʻe?
Ke hoʻohālikelike ʻia me ka graphite crucible: ʻoi aku ka kūpaʻa o kā mākou crucible i ka oxidation, kūpono no ka ʻenekini hoʻoheheʻe ʻana, a me ka conductivity thermal kiʻekiʻe.
Hoʻohālikelike ʻia me ka pālolo: ʻAʻole maʻalahi kā mākou crucible e haki a hoʻololi paha i nā wela kiʻekiʻe a ʻoi aku ka maikaʻi no nā noi wela kiʻekiʻe.
Ke hoʻohālikelike ʻia me ka ceramic crucible: ʻoi aku ka ikaika o kā mākou crucible i ke kūpaʻa haʻalulu wela a ʻoi aku ka wikiwiki a me ka hoʻomehana like ʻole.
I nā hoʻokolohua hoʻohālikelike he nui me nā hoa kūloko a me nā haole, ke alakaʻi nei kā mākou silicon carbide crucible me kāna hana maikaʻi loa a me ke ola lawelawe lōʻihi.
Ka loiloi mea hoʻohana
Manaʻo nui nā mea kūʻai aku ma hope o ka hoʻohana ʻana:
"He kiʻekiʻe loa ka maikaʻi o ka hoʻoili wela, kahi e hōʻemi nui ai i kā mākou manawa hana."
"He maikaʻi loa ka pale ʻana i ka corrosion, a ʻoi aku ka maikaʻi o ka loko o ka crucible e like me ka mea hou ma hope o nā mahina o ka hoʻohana ʻana."
"He ikaika a paʻa loa, hoʻohana pinepine a hoʻohana me ka ʻole o ka māwae, maʻalahi loa."
Inā ʻoe e ʻimi nei i kahi Crucible wela kiʻekiʻe me ka hana hilinaʻi a me ka lōʻihi, a laila ʻo kā mākou Silicon Carbide Crucible ʻo ia kāu koho maikaʻi loa. Inā ʻoe e hana nei i ka hoʻoheheʻe metala, ka hana aniani a i ʻole nā māla wela kiʻekiʻe, hiki iā mākou ke hāʻawi iā ʻoe i nā hopena huahana kūpono.
E kelepona mai iā mākou i kēia lā no nā kikoʻī hou aku a i ʻole e noi i kahi laʻana!
E ʻae i kā mākou kīʻaha carbide kiʻekiʻe kiʻekiʻe i kou lima ʻākau i ka hana wela kiʻekiʻe!
