Mea hoʻomehana graphite
Hoʻohana ʻia nā mea hoʻomehana graphite i ka umu wela wela me ka mahana i hiki i ka 2200 degere ma ke kaiapuni vacuum a me 3000 degere i loko o ka deoxidized a hoʻokomo ʻia ke kinoea.
ʻO nā hiʻohiʻona nui o ka graphite heater:
1. kūlike o ka hoʻolālā hoʻomehana.
2. maikaʻi uila conductivity a kiʻekiʻe uila ukana.
3. pale ʻana i ka corrosion.
4. inoxidizability.
5. kiʻekiʻe kemika maemae.
6. ikaika mechanical kiʻekiʻe.
ʻO ka pōmaikaʻi, ʻoi aku ka maikaʻi o ka ikehu, ka waiwai kiʻekiʻe a me ka mālama haʻahaʻa.
Hiki iā mākou ke hana i ka anti-oxidation a me ke ola lōʻihi o ka graphite crucible, graphite mold a me nā ʻāpana āpau o ka graphite heater.
Nā palena nui o ka mea hoʻomehana graphite:
Hōʻike ʻenehana | VET-M3 |
ʻAiʻi Nui (g/cm3) | ≥1.85 |
Maʻiʻo Lehu (PPM) | ≤500 |
Kahakai ʻoʻoleʻa | ≥45 |
Kū'ē Kūikawā (μ.Ω.m) | ≤12 |
ʻO ka ikaika lohi (Mpa) | ≥40 |
Ka ikaika hoʻoemi (Mpa) | ≥70 |
Max. Ka nui o ka palaoa (μm) | ≤43 |
Coefficient o ka hoonui wela Mm/°C | ≤4.4*10-6 |
ʻO ka mea hoʻomehana graphite no ka umu uila he mau waiwai o ka pale ʻana i ka wela, ke kū ʻana o ka oxidation, ka conductivity uila maikaʻi a me ka ʻoi aku o ka ikaika mechanical. Hiki iā mākou ke mīkini i nā ʻano mea hoʻomehana graphite e like me nā hoʻolālā o nā mea kūʻai aku.
