Ke kālele nei hoʻi mākou i ka hoʻomaikaʻi ʻana i ka hoʻokele mea a me ka papahana QC i hiki ai iā mākou ke mālama i ka pōmaikaʻi nui i loko o ka ʻoihana hoʻokūkū ikaika no OEM Supply China Aln AinKaila Nitride Aluminime ka Insulation Kiʻekiʻe, loaʻa iā mākou ʻehā mau hoʻonā alakaʻi. ʻOi aku ka maikaʻi o kā mākou huahana i kūʻai ʻia aku ʻaʻole wale i ka wā o ka mākeke Kina, akā hoʻokipa ʻia hoʻi i ka wā o ka ʻoihana honua.
Ke kālele nei hoʻi mākou i ka hoʻomaikaʻi ʻana i ka hoʻokele waiwai a me ka papahana QC i hiki ai iā mākou ke mālama i ka pōmaikaʻi nui i loko o ka ʻoihana hoʻokūkū ikaika noKaila Nitride Alumini, Kina Alumini Nitride, Hoʻokuʻu ʻia aku kā mākou huahana ma ka honua holoʻokoʻa. Ua māʻona mau kā mākou mea kūʻai aku me kā mākou kūlana hilinaʻi, nā lawelawe i hoʻonohonoho ʻia i ka mea kūʻai aku a me nā kumukūʻai hoʻokūkū. ʻO kā mākou misionari "e hoʻomau i ka loaʻa ʻana o kou kūpaʻa ma ka hoʻolaʻa ʻana i kā mākou mau hana i ka hoʻomaikaʻi mau ʻana i kā mākou mau mea a me nā lawelawe i mea e hōʻoia ai i ka ʻoluʻolu o kā mākou mea hoʻohana hope, nā mea kūʻai aku, nā limahana, nā mea hoʻolako a me nā kaiāulu o ka honua a mākou e hana pū nei".
Nā hui kalapona / kalapona(ma hope aku nei i 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.
Ke hoʻohālikelike ʻia me nā mea graphite maʻemaʻe kiʻekiʻe, hoʻomaka ka graphite e oxidize ma 400C, kahi e nalowale ai ka pauka ma muli o ka oxidation, e hopena ana i ka haumia o ke kaiapuni i nā mea peripheral a me nā keʻena vacuum, 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 ka kemika ma 1600 degere, Hoʻohana nui ʻia ia i ka ʻoihana hou, ʻoi aku hoʻi i ka ʻoihana semiconductor.
Hāʻawi kā mākou hui i nā lawelawe hana uhi SiC ma ke ʻano CVD ma luna o ka ʻili o ka graphite, nā keramika a me nā mea ʻē aʻe, i hiki ai i nā kinoea kūikawā e loaʻa ana ke kalapona a me ka silicon ke hana i ka mahana kiʻekiʻe e loaʻa ai nā molekala SiC maʻemaʻe kiʻekiʻe, nā molekala i waiho ʻia ma luna o ka ʻili o nā mea i uhi ʻia, e hana ana i ka papa pale SIC. Hoʻopaʻa paʻa ʻia ka SIC i hoʻokumu ʻia i ke kumu graphite, e hāʻawi ana i ke kumu graphite i nā waiwai kūikawā, no laila e hana ana i ka ʻili o ka graphite i paʻa, ʻaʻohe Porosity, kū'ē i ke ana wela kiʻekiʻe, kū'ē i ka corrosion a me ke kū'ē i ka oxidation.
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.
