7. Mafunso Ofunsidwa Kawirikawiri (FAQ)
Q1: N’chifukwa chiyani ma crucible a graphite osasinthika ndi abwino kuposa ma crucible a graphite otulutsidwa?
Graphite ya isostatic imapangidwa pogwiritsa ntchito kupanikizika kwa isotropic hydrostatic, zomwe zimapangitsa kuti kapangidwe kake kakhale kofanana (chiŵerengero cha isotropy 1.05–1.25). Graphite yotulutsidwa imakhala ndi mawonekedwe ofanana a tinthu tating'onoting'ono, zomwe zimapangitsa kuti kutentha kukhale kosiyana komanso kusweka panthawi ya kutentha.
Q2: Kodi graphite oxidation imayamba kutentha bwanji?
Mu mlengalenga wotseguka wokhala ndi mpweya, graphite imayamba kusungunuka pa kutentha kwa pafupifupi 400 °C. Mu mlengalenga wopanda mpweya kapena mpweya wopanda mpweya (Argon/Nayitrogeni), graphite ya VET Energy yoyera kwambiri imapirira kutentha mpaka 2760 °C.
Q3: Kodi kuchuluka kwa phulusa kumakhudza bwanji kuyeretsa chitsulo chamtengo wapatali?
Phulusa limayimira zinthu zosafunika (monga Fe, Al, Si). Pa kutentha kwakukulu, zinthu zosafunikazi zimafalikira kukhala golide wosungunuka kapena siliva, zomwe zimasintha kusalala ndi kunyezimira. VET Energy's ≤ 5 ppm ultra-pure grade imachotsa zoopsa za kuipitsidwa.
Q4: Kodi VET Energy ingapereke ma geometries apadera ndi zokutira zapadera?
Inde. Timapanga ma geometries apadera, zophimba zokhala ndi ulusi, ndi mapangidwe okhala ndi mabowo ambiri, okhala ndi zokutira za CVD Silicon Carbide (SiC) kuti tiwonjezere kukana kuwonongeka, kuteteza okosijeni, komanso kusagwira bwino ntchito kwa mankhwala.
