Ukuze uvimbele ukulimala kokugqwala okubangelwa i-oxidation ye-flake graphite ekushiseni okuphezulu, kuyadingeka ukuthola into yokubeka ijazi endaweni yokushisa ephezulu, engavikela ngokuphumelelayo i-flake graphite kusuka ku-oxidation ekushiseni okuphezulu. Ukuze sithole lolu hlobo lwejazi le-flake graphite anti-oxidation, kufanele siqale sibe nezici ezithile ezinjengokumelana nezinga lokushisa eliphezulu, ukubumbana okuhle, ukusebenza kahle kwe-anti-corrosion, ikhono eliqinile lokulwa ne-oxidation nobulukhuni obuphezulu. Abahleli abalandelayo be-Furuite graphite babelana ngezindlela zokuvimbelai-flake graphitekusuka ekufakweni nge-oxidized ezingeni lokushisa eliphezulu:
1. Sebenzisa izinto ezinomfutho womhwamuko ongaphansi kuka-0.1333MPa(1650℃) kanye nezakhiwo ezinhle ezihlanganisa konke.
2. Khetha impahla yesigaba sengilazi ehlangabezana nezidingo zokusebenza njengezinto ezizivalayo, futhi ukwenze kube into yokuvala uphawu lokuqhekeka ezingeni lokushisa elisebenzayo.
3. Ngokomsebenzi wamandla amahhala ajwayelekile wokusabela komoyampilo onezinga lokushisa, ezingeni lokushisa lokwenza insimbi (1650-1750℃), izinto ezisondelene kakhulu nomoya-mpilo kunekhabhoni-oksijeni zikhethwa ukuthi zithathe umoya-mpilo kuqala, ukuze ukuze oxidize ngokwabo futhi ukuvikelai-flake graphite. Umthamo wesigaba esisha esikhiqizwe ngemva kwe-oxidation mkhulu kunesigaba sokuqala, esiwusizo ukuvimba umzila wokusabalalisa ongaphakathi we-oksijeni futhi wenze umgoqo we-oxidation.
4. Emazingeni okushisa okusebenza, inani elikhulu lezinto ezifakiwe ezifana ne-Al2O3, SiO2 ne-Fe2O3 ensimbi encibilikisiwe zingakhangiswa, ezisabela ngokwazo ku-sinter, ukuze ukufakwa okuhlukahlukene okuvela ensimbi encibilikisiwe kungene kancane kancane embozweni.
I-Furuite graphite isikhumbuza ukuthi izinga lokushisa le-oxidation le-flake graphite ezindaweni ezikhiqizayo zase-China ngu-560815℃ lapho okuqukethwe kwekhabhoni kungu-88%96% futhi usayizi wezinhlayiyana ungaphezu kuka -400 mesh. Phakathi kwazo, lapho usayizi wezinhlayiyana zegraphite ungu-0.0970.105mm, izinga lokushisa le-oxidation legraphite elinokuqukethwe kwekhabhoni engaphezu kuka-90% lingu-600815℃ kanye nelegraphite elinokuqukethwe kwekhabhoni engaphansi kuka-90% ngu-62075 ℃. I-crystalline eyengeziwei-flake graphiteukuthi, izinga lokushisa eliphakeme le-oxidation liphezulu, futhi kuyancipha ukuncipha kwesisindo se-oxidation ezingeni lokushisa eliphezulu.
