7. Imibuzo Evame Ukubuzwa (Imibuzo Evame Ukubuzwa)
Q1: Kungani izimbobo ze-graphite ezi-isostatic zingcono kunezimbobo ze-graphite ezikhishwe?
I-graphite ye-isostatic ihlanganiswa kusetshenziswa ingcindezi ye-isotropic hydrostatic, ihlinzeka ngezakhiwo ezifanayo (isilinganiso se-isotropy 1.05–1.25). I-graphite ekhishwe ifaka ukuhambisana kokusanhlamvu okuqondiswe ohlangothini, okuholela ekwandeni okungalingani kokushisa kanye nokuqhekeka ngesikhathi sokushaqeka kokushisa.
Umbuzo 2: Kuqala ngaliphi izinga lokushisa lapho i-oxidation ye-graphite iqala khona?
Esimweni esivulekile esiqukethe umoya-mpilo, i-graphite iqala uku-oxidiza cishe ku-400 °C. Esimweni segesi esingenawo umoya noma esingenawo umoya (i-Argon/Nitrogen), i-VET Energy high-purity graphite imelana namazinga okushisa afinyelela ku-2760 °C.
Umbuzo 3: Ukuqukethwe komlotha kukuthinta kanjani ukucwengisiswa kwensimbi eyigugu?
Umlotha umelela ukungcola kwezinto eziyisisekelo (isb., i-Fe, i-Al, i-Si). Emazingeni okushisa aphezulu, lokhu kungcola kusakazeka kube yigolide elincibilikisiwe noma isiliva, okushintsha ubucwebe kanye nokukhanya. I-VET Energy's ≤ 5 ppm ultra-pure grade iqeda izingozi zokungcola.
Umbuzo 4: Ingabe i-VET Energy ingahlinzeka ngamajiyometri enziwe ngokwezifiso kanye nokumbozwa okukhethekile?
Yebo. Sakha amajiyometri ngokwezifiso, izembozo ezinemicu, kanye nemiklamo enezimbobo eziningi, kanye ne-CVD Silicon Carbide (SiC) coating ukuze sithuthukise ukumelana nokuguguleka, ukuvikelwa kwe-oxidation, kanye nokungasebenzi kahle kwamakhemikhali.
8. Ukubonisana Okufingqiwe Nokuthola Imithombo
Isebenzisa okuqukethwe komlotha okuphansi kakhulu (≤ 5 ppm), ukuminyana okukhulu, kanye nokushisa okuphezulu (110–130 W/(m·K)), izitsha ze-VET Energy ezicwebezelayo ze-isostatic graphite ezihlanzekile kakhulu zinikeza ukusebenza okuhlala isikhathi eside kwe-metallurgy yezimboni, ukudonsa ngekristalu, kanye nokwelashwa kokushisa kwelabhorethri. I-VET Energy inikeza uchungechunge lokuhlinzeka oluvela ekugcineni kuya ekugcineni—kusukela ekulungiseleleni izinto zokusetshenziswa kanye nomshini we-CNC kuya ekumbozweni kwe-CVD SiC okuthuthukisiwe.
