Ka ninini ʻana metala i hoʻoheheʻe ʻia ma ka Graphite Crucible
NA HI'O HUA
Heheʻe wikiwiki
Hoʻonui ka graphite thermal conductivity kiʻekiʻe i ka hana wela ma 30%, e hōʻemi nui ana i ka manawa hoʻoheheʻe.
ʻOi aku ka pale ʻana i ka haʻalulu wela
ʻO ka ʻenehana hoʻopaʻa ʻia ʻo Resin ke kū i ka hoʻomehana wikiwiki a me ka hoʻoluʻu ʻana, e ʻae ana i ka hoʻopiʻi pololei ʻana me ka haki ʻole.
Kūʻokoʻa Paʻa
ʻO ka ikaika mechanical kiʻekiʻe e kū'ē i ka hopena kino a me ka hoʻoheheʻe kemika no ka lōʻihi o ke ola lawelawe.

KA HANA
1. Hoʻoponopono pololei
ʻO ka graphite maʻemaʻe kiʻekiʻe + carbide silicon premium + mea hoʻopaʻa paʻa waiwai.
.
2.Isostatic Pressing
ʻO ka nui a hiki i ka 2.2g/cm³ | ʻO ka mānoanoa o ka pā ± 0.3m
.
3.High-Temperature Sintering
ʻO ka recrystallization ʻāpana SiC e hana ana i ka ʻōnaehana pūnaewele 3D
.
5.ʻO ka nānā ʻana i ka maikaʻi
Helu hoʻopaʻa inoa kūʻokoʻa no ka hiki ʻana o ke ola holoʻokoʻa
.
4. Hoʻonui i ka ʻili
ʻO ka uhi anti-oxidation → 3 × hoʻomaikaʻi i ka pale ʻana i ka corrosion
.
6.Hoʻopili palekana
ʻO ka papa haʻihaʻi haʻihaʻi + ʻaʻa wai + ka pahu hoʻoikaika ʻia

FAQ
Q1: Hiki i ka Crucible Cover ke hoʻemi i nā kumukūʻai ikehu?
A: ʻOiaʻiʻo! Hoʻemi ia i ka nalowale o ka wela, ʻoki i ka hoʻohana ʻana i ka ikehu a hiki i 30%.
Q2: He aha nā kapuahi i kūpono?
A: He mea maʻalahi - kūpono no ka hoʻokomo ʻana, ke kinoea, a me nā umu uila.
Q3: He palekana ka graphite silicon carbide no nā wela kiʻekiʻe?
A: ʻAe. ʻO kona kūpaʻa wela a me ke kemika e kūpono ia no nā kūlana koʻikoʻi.
Q4: Pehea e pale ai i ka crucible cracking?
Mai hoʻouka i ka mea anuanu i loko o kahi kīʻaha wela (max ΔT <400°C).
Ka helu hoʻoluʻu ma hope o ka hoʻoheheʻe ʻana <200°C / hola.
E hoʻohana i nā ʻōpala crucible i hoʻolaʻa ʻia (e pale i ka hopena mechanical).
Q5: Pehea e pale aku ai i ka haki ʻana o ka crucible?
Mai hoʻouka i ka mea anuanu i loko o kahi kīʻaha wela (max ΔT <400°C).
Ka helu hoʻoluʻu ma hope o ka hoʻoheheʻe ʻana <200°C / hola.
E hoʻohana i nā ʻōpala crucible i hoʻolaʻa ʻia (e pale i ka hopena mechanical).
Q6: Pehea ʻoe e mālama ai i nā uku?
- Pono mākou i kahi waihona 30% ma o T / T, me ke koena ma mua o ka lawe ʻana. Hāʻawi pū mākou i nā kiʻi huahana ma mua o ka uku hope.
- Q7: He aha nā koho i loaʻa iaʻu ma mua o ke kau ʻana i kahi kauoha?
- Hiki iā ʻoe ke noi i nā laʻana mai kā mākou hui kūʻai aku e loiloi i kā mākou huahana.
- Q8: Aia ka helu kauoha liʻiliʻi?
ʻAʻole, hoʻokō mākou i nā kauoha e pili ana i kāu mau pono kikoʻī, me ka ʻole o kahi koi liʻiliʻi.
Mākaukau e hoʻonui i kāu mau hana hoʻoheheʻe metala? E kelepona mai iā mākou i kēia lā e ʻike pehea e hiki ai i kā mākou Pure Graphite Crucibles ke hoʻololi i kāu kaʻina hana!
