Nā hui kalapona / kalapona(ma hope aku nei e kapa ʻia ʻo "C / C a i ʻole CFC") he ʻano mea hui i hoʻokumu ʻia ma ke kalapona a hoʻoikaika ʻia e ke kalapona fiber a me kāna huahana (carbon fiber preform). Loaʻa iā ia ka inertia o ke kalapona a me ka ikaika kiʻekiʻe o ke kalapona fiber. Loaʻa iā ia nā waiwai mechanical maikaʻi, ke kūpaʻa wela, ke kūpaʻa corrosion, ka damping friction a me nā ʻano conductivity thermal a me ka uila.
CVD-SiCʻO ka uhi ʻana he mau ʻano o ke ʻano like, ka mea paʻa, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa ʻokikene, ka maʻemaʻe kiʻekiʻe, ke kūpaʻa waikawa a me ka alkali a me ka reagent organik, me nā waiwai kino a me nā kemika paʻa.
Nā hiʻohiʻona nui:
1. Ke kūpaʻa ʻana i ka oxidation wela kiʻekiʻe:He maikaʻi loa nō ke kūpaʻa ʻana i ka oxidation ke kiʻekiʻe ka mahana i 1600 C.
2. Maʻemaʻe kiʻekiʻe: hana ʻia e ka waiho ʻana o ka mahu kemika ma lalo o ke kūlana chlorination wela kiʻekiʻe.
3. Ke kūpaʻa ʻana i ka ʻino: paʻakikī kiʻekiʻe, ʻili paʻa, nā ʻāpana maikaʻi.
4. Ke kūpaʻa ʻana i ka palaho: waikawa, alkali, paʻakai a me nā reagents organik.

ʻO VET Energy ka mea hana maoli o nā huahana graphite a me silicon carbide i hoʻopilikino ʻia me nā uhi like ʻole e like me ka uhi ʻana o SiC, ka uhi ʻana o TaC, ka uhi ʻana o ke kalapona aniani, ka uhi ʻana o ke kalapona pyrolytic, a me nā mea ʻē aʻe, hiki ke hoʻolako i nā ʻāpana like ʻole no ka ʻoihana semiconductor a me ka photovoltaic.
Loaʻa kā mākou hui loea mai nā ʻoihana noiʻi kūloko kiʻekiʻe, hiki ke hāʻawi i nā hoʻonā mea ʻoihana hou aku nāu.
Ke hoʻomau nei mākou i ka hoʻomohala ʻana i nā kaʻina hana holomua e hoʻolako i nā mea holomua hou aʻe, a ua hana i kahi ʻenehana i hoʻopaʻa ʻia, hiki ke hoʻopaʻa i ka pilina ma waena o ka uhi a me ka substrate a emi iki ka maʻalahi o ka hemo ʻana.
Ke hoʻokipa maikaʻi nei iā ʻoe e kipa i kā mākou hale hana, e kūkākūkā hou aku kākou!
