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 ʻoluʻolu (Mpa) | ≥40 |
Ka ikaika hoʻoemi (Mpa) | ≥70 |
Max. Ka nui o ka palaoa (μm) | ≤43 |

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.
FAQ
Nīnau: He hui kālepa a mea hana paha ʻoe?
A: He ʻoi aku mākou ma mua o 10 ʻoihana vears me ka iso9001 i hōʻoia ʻia
Q: Pehea ka lōʻihi o kāu manawa hoʻouna?
A: ʻO ka maʻamau he 3-5 mau lā inā loaʻa nā waiwai, a i ʻole 10-15 mau lā inā ʻaʻole i loko o nā waiwai, e like me kāu nui.
Q: Pehea e hiki ai iā Iget ka laʻana e nānā i kou maikaʻi?
A: Ma hope o ka hōʻoia ʻana o ke kumukūʻai, hiki iā ʻoe ke koi i nā laʻana e nānā i ka maikaʻi o kā mākou huahana. Inā makemake ʻoe i kahi laʻana hakahaka e nānā i ka hoʻolālā a me ka maikaʻi, e hāʻawi mākou iā ʻoe i kahi laʻana no ka manuahi ʻoiai ʻoe e hāʻawi i ka ukana hōʻike.
Q: He aha kāu mau ʻōlelo uku?
A: Keʻae nei mākou i ka uku e ka Western union, Pavpal, Alibaba, T / TL / Cetc..no ka hoʻonohonoho nui, hana mākou i ka 30% waiho koena ma mua o ka hoʻounaʻana.
