He mea hana akamai mākou. Ke lanakila nei i ka hapa nui o nā palapala hōʻoia koʻikoʻi o kāna mākeke no ka mea kūʻai hilinaʻi Kina RP/HP/UHP High Quality Graphite Columan, kono mākou iā ʻoe a me kāu hui e ulu pū me mākou a kaʻana like i kahi wā e hiki mai ana i ka mākeke honua.
He mea hana akamai mākou. Ke lanakila nei i ka hapa nui o nā palapala hōʻoia koʻikoʻi o kāna mākeke noKina Electrode, Electrode graphite, Hoʻolālā mau kā mākou ʻoihana R&D me nā manaʻo kiʻi hou i hiki iā mākou ke hoʻolauna i nā ʻano hana hou i kēlā me kēia mahina. ʻO kā mākou mau ʻōnaehana hoʻokele hana koʻikoʻi e hōʻoia mau i nā waiwai paʻa a kiʻekiʻe. Hāʻawi kā mākou hui kālepa i nā lawelawe kūpono a maikaʻi. Inā loaʻa kekahi hoihoi a me ka nīnau e pili ana i kā mākou huahana a me nā hoʻonā, e hoʻomanaʻo e hoʻopili iā mākou i ka manawa. Makemake mākou e hoʻokumu i kahi pilina ʻoihana me kāu hui hanohano.
Kaona / kalapona composites('ōlelo ʻia ma hope aku ʻo "C / C a i ʻole CFC”) he ʻano mea hoʻohui i hoʻokumu ʻia ma ke kalapona a hoʻoikaika ʻia e ka fiber kalapona a me kāna mau huahana (carbon fiber preform). Loaʻa iā ia ka inertia o ke kalapona a me ka ikaika kiʻekiʻe o ke kalapona kalapona. Loaʻa iā ia nā waiwai mechanical maikaʻi, ke kūpaʻa wela, ka pale ʻana i ka corrosion, friction damping a me nā ʻano conductivity thermal a me ka uila
CVD-SiCʻO ka uhi ʻana i nā hiʻohiʻona o ke ʻano like ʻole, nā mea paʻa, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka oxidation, ka maʻemaʻe kiʻekiʻe, ke kūpaʻa a me ka alkaline a me ka reagent organik, me nā waiwai paʻa kino a me nā kemika.
Ke hoʻohālikelike ʻia me nā mea graphite maʻemaʻe kiʻekiʻe, hoʻomaka ka graphite e oxidize ma 400C, ka mea e hoʻopau ai i ka pauka ma muli o ka oxidation, ka hopena i ka pollution kaiapuni i nā ʻaoʻao peripheral a me nā keʻena māmā, a hoʻonui i nā haumia o ke kaiapuni maʻemaʻe kiʻekiʻe.
Eia nō naʻe, hiki i ka uhi ʻana o SiC ke mālama i ke kūpaʻa kino a me ke kemika ma 1600 degere, hoʻohana nui ʻia i ka ʻoihana hou, ʻoi loa i ka ʻoihana semiconductor.
Hāʻawi kā mākou hui i nā lawelawe kaʻina hana hoʻoheheʻe SiC ma ke ʻano CVD ma ka ʻili o ka graphite, ceramics a me nā mea ʻē aʻe, i hiki ai i nā kinoea kūikawā i loaʻa ke kalapona a me ke silika i ke kiʻekiʻe kiʻekiʻe e loaʻa ai nā molekala SiC maʻemaʻe kiʻekiʻe. e hana ana i ka papa pale SIC. Hoʻopili paʻa ʻia ka SIC i hoʻokumu ʻia i ka base graphite, e hāʻawi ana i ka graphite base i nā waiwai kūikawā, pēlā e hana ai i ka ʻili o ka graphite compact, Porosity-free, kiʻekiʻe wela ke kū ʻana, ka pale ʻana i ka corrosion a me ka pale oxidation.
Nā hiʻohiʻona nui:
1. Kiʻekiʻe wela oxidation kū'ē:
ʻoi aku ka maikaʻi o ka pale ʻana i ka oxidation ke kiʻekiʻe ka mahana e like me 1600 C.
2. Maʻemaʻe kiʻekiʻe: hana ʻia e ka hoʻoheheʻe ʻana i ka mahu ma lalo o ke kūlana chlorination kiʻekiʻe.
3. Erosion kū'ē: kiʻekiʻe paakiki, paʻaʻiliʻili, maikaʻi particles.
4. Ke kū'ē i ka corrosion: acid, alkali, paʻakai a me nā mea hoʻoulu.
