Nā hiʻohiʻona

ʻO Sic Crucibles, hana mua ʻia mai ka silicon carbide, hoʻohana nui ʻia i nā ʻoihana kahi mea koʻikoʻi ke kiʻekiʻe o ka mahana a me ke kūʻē kemika. Ua lilo kēia mau crucibles i mea e koho ai no nā foundries a me nā laboratories ma muli o ko lākou ʻoi aku ka lōʻihi o ka lōʻihi, i mea nui ia no nā kaʻina hana e like me ka hoʻoheheʻe metala, ka hoʻolei ʻana, a me ka hoʻomaʻemaʻe.

Introduction to Sic Crucibles

Ke Kino a me Kemika oʻO Sic Crucibles

Ke koho ʻana i nā crucibles no nā noi ʻoihana, ʻo ka hoʻomaopopo ʻana i nā ʻōlelo kuhikuhi kino a me nā kemika he mea koʻikoʻi. Aia ma lalo iho kahi haʻihaʻi o nā waiwai koʻikoʻi o ISO Type Sic Crucibles:

Na Waiwai Kino Papa kuhikuhi
ʻO ka refractoriness ≥ 1650°C
ʻIke ʻia ka Porosity ≤ 20%
ʻAiʻi Nui ≥ 2.2 g/cm²
Ka ikaika ʻohi ≥ 8.5 MPa
Hoʻohui Kimia Papa kuhikuhi
ʻO ke kalapona (C%) 20–30%
Silicon Carbide (SiC%) 50–60%
alumina (AL2O3%) 3–5%

Hāʻawi kēia mau hiʻohiʻona iā Sic Crucibles i ka conductivity thermal kūikawā, ka hoʻonui haʻahaʻa haʻahaʻa, a me ke kūpaʻa ʻana i ka corrosion kemika, e hōʻoiaʻiʻo ana e hana maikaʻi lākou i nā wahi ʻoi loa.

Pono o Sic Crucibles

  1. Kū'ē Kūlana Kiʻekiʻe: Hiki i nā Sic Crucibles ke kū i nā mahana a hiki i ka 1650 ° C, no ka hoʻoheheʻe metala a me nā noi wela kiʻekiʻe.
  2. Ka lōʻihi a me ka lōʻihi: Me ka ikaika paʻi ikaika o ≥ 8.5 MPa, hiki i kēia mau crucibles ke hoʻomanawanui i nā koʻikoʻi mechanical e pili ana i nā ʻoihana ʻoihana me ka ʻole o ka haki ʻana a i ʻole deforming.
  3. Paʻa Kemika: Hāʻawi ka ʻike kiʻekiʻe kiʻekiʻe carbide (50-60%) i ke kūpaʻa maikaʻi loa i nā hopena kemika, e hōʻoiaʻiʻo ana i ka lōʻihi o ke ola ʻana ʻoiai ke ʻike ʻia i nā metala hoʻoheheʻe ʻia a i ʻole nā ​​​​kemika ikaika.

Ka mālama pono ʻana a me ka mālama ʻana i nā Sic Crucibles

No ka hoʻonui i ke ola o Sic Crucibles a hōʻoia i kā lākou hana palekana, pono e hahai i kekahi mau alakaʻi mālama:

  • Hoomaemae mau: Pono e hoʻomaʻemaʻe mau ʻia nā kīʻaha e hoʻoneʻe i ke koena, e pale aku i ka haumia a me ka ʻino.
  • Hōʻalo i ka haʻalulu wela: He mea nui ka hoʻomehana ʻana a me ka hoʻoluʻu ʻana i mea e pale ai i ka haki ʻana. Hiki i ka hoʻololi koke ʻana o ka mahana ke haʻihaʻi ka mea.
  • Kāohi i ka ʻino kino: Hōʻalo i ka ʻike ʻana i nā kemika ʻino, ʻoi aku ka alkaline a i ʻole ka waiʻawaʻawa, hiki ke hoʻohaʻahaʻa i ka pono o ke kinona.

ʻIke kūpono no nā mea kūʻai

ʻO ke koho ʻana i ka Sic Crucible kūpono e pili ana i nā pono kikoʻī o kāu kaʻina hana ʻoihana. E noʻonoʻo i nā mea e like me ka mahana, ka hoʻohālikelike ʻana i nā mea, a me nā koi nui. Ma nā noi honua maoli, ua hōʻike ka nui o nā mea kūʻai aku i ka hōʻemi nui ʻana i nā kumukūʻai mālama a me ka hoʻonui ʻana i ka pono hana ma o ka hoʻololi ʻana iā Sic Crucibles.

ʻO Sic Crucibles kahi mea hana pono no nā ʻoihana e koi ana i nā mea hana kiʻekiʻe e hiki ai ke kū i ka wela wela a me ka ʻike kemika. Ma ka hoʻomaopopo ʻana i kā lākou mau waiwai a me ka hahai ʻana i nā protocol mālama pono, hiki i nā ʻoihana ke hoʻonui i ka hana hana ʻoiai e hōʻemi ana i ka downtime.
