7. Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa)
Q1: Sei zvigadziko zvegrafiti zvakaparadzana zviri nani pane zvigadziko zvegrafiti zvakaparadzana?
Graphite yeIsostatic inodzvinyirirwa uchishandisa isotropic hydrostatic pressure, ichipa hunhu hwakaenzana hwekuvaka (isotropy ratio 1.05–1.25). Graphite yakabviswa ine divi rakafanana, zvichikonzera kuwedzera kwekupisa kusina kuenzana uye kutsemuka panguva yekuvhunduka kwekupisa.
Mubvunzo wechipiri: Kupisa kwakadini kunotanga pa graphite oxidation?
Mumhepo yakavhurika ine okisijeni, girafiti inotanga kuoxidation panosvika 400 °C. Mumhepo ine vacuum kana inert gas (Argon/Nitrogen), VET Energy high-purity graphite inokwanisa kutsungirira tembiricha inosvika 2760 °C.
Mubvunzo wechitatu: Kuwanda kwedota kunokanganisa sei kunatswa kwesimbi inokosha?
Dota rinomiririra tsvina yezvinhu zvemuviri (semuenzaniso, Fe, Al, Si). Pakupisa kwakanyanya, tsvina iyi inopararira kuita goridhe rakanyungudutswa kana sirivha, zvichichinja kupenya kwayo. VET Energy's ≤ 5 ppm ultra-pure grade inobvisa njodzi dzekusvibiswa.
Mubvunzo wechina: Ko VET Energy inogona kupa ma geometries akagadzirwa uye ma coatings akasarudzika here?
Ehe. Tinogadzira ma geometries akagadzirwa nemaoko, ma threaded cover, uye madhizaini ane maburi akawanda, pamwe chete ne CVD Silicon Carbide (SiC) coatings kuti tiwedzere kusakara, dziviriro ye oxidation, uye kusashanda kwemakemikari.
