High kuchena graphite yakapfava inonzwa
Tsva Yekukurumidza:
1. Mamwe mazita: flexible graphite insulation inonzwa, semiconductor thermal field soft inonzwa, graphite yakanzwa.
2. Kushandisa: Thermal field insulation ye semiconductor, photovoltaic equipment, vacuum high pressure gas quenching furnace, monoclistallin silicon furnace uye mamwe ekudzivirira kwekushisa kwepamusoro.
3. Core parameters: kuchena ≥99.99%, yakanyanya kushivirira tembiricha 3000℃, thermal conductivity 0.15-0.24W/m·K.
tsananguro
Semixlab inotungamira mugadziri weyakanyanya kuchena graphite yakapfava inonzwa muChina, yakatarisana nekupa yakakwira mashandiro emafuta ekudzivirira ekugadzirisa semiconductor, photovoltaic uye yakanyanya tembiricha maindasitiri minda. Ichi chigadzirwa chinotora kunze kwenyika yakakwira-kuchena graphite raw material (kusachena kwemukati ≤0.1%), yakagadzirwa nefiber network chimiro kuburikidza neakakosha maitiro, uye ine hunhu hwemhando senge Ultra-low thermal conductivity (≤ 0.25W / m·K pa1000 ℃), yakanyanya kupisa tembiricha kuramba (kuenderera kushandiswa kwekushisa kwe3000, uye inovaka inert yakanaka yeXNUMX yemakemikari. precision thermal field system.
Yakakwira-kuchena graphite yakapfava inonzwa ndiyo yakakosha insulation zvinhu kune thermal field system ye semiconductor uye photovoltaic midziyo. Kuburikidza nekunyatsoruka uye kurongedza kwepamusoro-kuchena graphite fibers, porous chimiro chine yakaderera thermal conductivity inoumbwa. Munzvimbo dzetembiricha yepamusoro (semuenzaniso, pamusoro pe800 ℃), inoderedza zvakanyanya kurasikirwa nekupisa nekuratidzira kupisa kunopenya uye nekudzikisa yakasimba-chikamu chekupisa nzira.
Zvinoenderana nekusiyana kwezvinhu zvakabikwa, zvigadzirwa zvakakamurwa muzvikamu zvitatu:
PAN-yakavakirwa graphite yakapfava yakanzwa: yakanakisa mechini zvivakwa, yakapusa yekugadzira maitiro, yakashandiswa zvakanyanya mune zvimiro zvekutsigira zvinhu.
Viscose-yakavakirwa graphite yakapfava inonzwa: yakasimba ablative kuramba, yakakwirira tekinoroji kuoma, yakakodzera kune yakakwira tembiricha yekupisa kupisa nzvimbo.
Pitch-based graphite yakapfava inonzwa: yakapfuma mune zvigadzirwa, yakakwira carbonization goho, asi musika application idiki.

Applications
1. Semiconductor kugadzira michina
Single crystal silicon kukura system:
MuCZ nzira imwechete yekristaro choto, iyo graphite heater uye quartz crucible yakaputirwa kuti iwane kutonga kwakaringana kwekunyungudusa tembiricha gradient (axial tembiricha mutsauko ≤2℃/cm) uye ive nechokwadi kugadzikana kweimwe kristaro kukura mwero.
Silicon carbide crystal kukura choto:
Kana nzira yePVT ikashandiswa, iyo yakapfava inonzwa seyepakati yekuvharisa layer inogona kuwedzera kufanana kweaxial thermal field muchoto ne40%, uye kuderedza crystal defect rate kusvika <0.5/cm².
2. Photovoltaic industry equipment
Polycrystalline ingot furnace:
Iyo modular dhizaini dhizaini inovandudza kupisa kwechoto kusvika pa85%, inova 30% yekuchengetedza simba kana ichienzaniswa neyekare kabhoni yakaoma kunzwa.
3. High tembiricha maindasitiri midziyo
Iyo yekudzima kutonhora kweyero yekupisa yekuvharidzira lining mukamuri yekudziya yevacuum yakanyanya kudzvanywa gasi yekudzima vira inowedzerwa ne20%.
Iyo ine simba yekuisa chisimbiso mu sintering zone yevacuum sintering vira inoderedza kushandiswa kwegasi reargon ne15%.
Kukwikwidza Kunobatsira
Ultra-yakakwirira kuchena: madota ≤500ppm, 200ppm, 20ppm, inogona kugadzirwa.
Yakanyanya kupisa tembiricha kuramba: yakanyanya tembiricha yekushanda 3000 ℃.
Acid uye alkali corrosion resistance: (PH 2-12), zero reactivity.
Tekinoroji mhinduro yekugadzirisa: yekupisa munda simulation + kusarudzwa kwezvinhu zvakabatanidzwa dhizaini.
Kusiyanisa zvakanakira: 200% yakakwirira tembiricha kuramba pane yechinyakare kabhoni yakanzwa, 50% yakaderera yekupisa conductivity pane yemakwikwi graphite yakanzwa, tsigira yakasimba yekuisa chisimbiso system yekubatanidza.
