Hunhu hwesilicon carbide yakagadziriswazve
Silicon carbide (R-SiC) yakagadzirwazve ine simba guru uye kuomarara kuri pamusoro pedhaimani, iyo inoumbwa pakupisa kwakanyanya kupfuura 2000℃. Inoramba iine hunhu hwakanaka hweSiC, hwakadai sekusimba kwekupisa kwakanyanya, kuramba ngura kwakasimba, kuramba oxidation kwakanaka, kuramba kupisa kwakanyanya nezvimwewo.
● Hunhu hwakanaka kwazvo hwemakanika. Silicon carbide yakagayiwazve ine simba rakawanda uye kuomarara kupfuura carbon fiber, inodzivirira zvakanyanya, inogona kuita basa rakanaka munzvimbo dzinopisa zvakanyanya, inogona kuita basa riri nani mumamiriro akasiyana-siyana. Pamusoro pezvo, inewo kuchinjika kwakanaka uye haikuvadzwi nyore nyore nekutambanudza nekukotama, izvo zvinovandudza zvikuru mashandiro ayo.
● Kudzivirira ngura zvakanyanya. Silicon carbide yakadzokororwa ine kudzivirira ngura zvakanyanya kune zvakasiyana-siyana zvemidziyo, inogona kudzivirira kuparadzwa kwemhando dzakasiyana dzemidziyo inoparadza, inogona kuchengetedza hunhu hwayo hwemakanika kwenguva yakareba, ine kunamira kwakasimba, kuitira kuti ive nehupenyu hwakareba hwekushanda. Pamusoro pezvo, inewo kugadzikana kwakanaka kwekupisa, inogona kuchinjika kune mamwe marudzi ekuchinja kwekushisa, uye inovandudza mashandiro ayo.
● Kusvina hakutsvedzi. Nekuti maitiro ekusvina haatsvedzi, hapana kushushikana kunoramba kuripo kunokonzera kucheneruka kana kutsemuka kwechigadzirwa, uye zvikamu zvine maumbirwo akaomarara uye kunyatsoita basa zvakanaka zvinogona kugadzirwa.

VET Energy ndiyo iyomugadziri chaiye wezvigadzirwa zve graphite ne silicon carbide zvakagadzirwa neCVD coating,anogona kupazvakasiyana-siyanazvikamu zvakagadzirirwa zve semiconductor uye photovoltaic industry. OChikwata chedu chehunyanzvi chinobva kumasangano makuru ekutsvagisa emuno, chinogona kupa mhinduro dzehunyanzvi.zvako.
Tinogara tichigadzira maitiro epamusoro-soro kuti tipe zvinhu zvepamusoro-soro,uyevakashanda tekinoroji ine patent yakasarudzika, iyo inogona kuita kuti kubatana pakati pekupenda ne substrate kuve kwakasimba uye kusanyanya kupatsanurwa.
