ʻO kā mākou misionari e ulu aʻe i mea hoʻolako hou i nā ʻenehana loea kiʻekiʻe a me nā mea kamaʻilio ma o ka hāʻawi ʻana i ka hoʻolālā a me ke ʻano kūpono, ka hana papa honua, a me nā mea lawelawe no ka hoʻemi nui ʻana ʻo China Pellet Igniter 120V / 230V Alumina Ceramic Pellet Igniter Heater no Biomass Boiler, ʻAʻole ʻoe e kali e launa pū me mākou inā makemake ʻoe i loko o kā mākou huahana a me nā hopena. Ke manaʻoʻiʻo nei mākou e ʻoluʻolu ʻoe i kā mākou huahana.
ʻO kā mākou misionari e ulu a lilo i mea hoʻolako hou i nā mea kiʻi kiʻi kiʻekiʻe a me nā mea kamaʻilio ma o ka hāʻawi ʻana i ka hoʻolālā a me ke ʻano kūpono, ka hana papa honua, a me nā hiki lawelaweʻO ka mea hoʻomehana seramika, Kina, Hiki ke hōʻoia ʻia ka maikaʻi maikaʻi, ke kumukūʻai hoʻokūkū, ka hāʻawi manawa a me ka lawelawe hilinaʻi. No nā nīnau hou aku e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou. Mahalo iā ʻoe - Ke hoʻoikaika mau nei kāu kākoʻo iā mākou.
MOCVD Substrate Heater, Mea Pumehana No MOCVD
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 |
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.
