Ukuze kuvinjelwe umonakalo wokugqwala obangelwa ukugqwala kwe-flake graphite ekushiseni okuphezulu, kuyadingeka ukuthola into yokufaka uboya ezintweni ezishisa kakhulu, ezingavikela ngempumelelo i-flake graphite ekugqwaleni ekushiseni okuphezulu. Ukuze sithole lolu hlobo lwe-flake graphite anti-oxidation coat, kumele siqale simelane nokushisa okuphezulu kanye nokuqina.
Ukumelana okuhle nokugqwala, ukumelana okunamandla nokugqwala, ubulukhuni obuphezulu nezinye izici. I-Furuite Graphite Xiaobian elandelayo yethula izindlela zokuvimbela i-flake graphite ukuthi ingagqwali lapho izinga lokushisa liphezulu:
1. Sebenzisa izinto ezinomfutho womusi ongaphansi kuka-0.1333MPa(1650*C) kanye nokusebenza okuhle okuphelele.
2. Khetha izinto zesigaba sengilazi ezihlangabezana nezidingo zokusebenza njengento ezivala yona, bese uzenza zibe izinto zokuvala eziqhekekile ekushiseni okusebenzayo.
3. Ngokomsebenzi wamandla akhululekile ajwayelekile okusabela nomoya-mpilo kanye nokushisa, ekushiseni kokwenza insimbi (1650-1750*C), izinto ezihambisana kakhulu nomoya-mpilo kune-carbon-oxygen zikhethwa ukuze zibambe umoya-mpilo ngokukhethekile, ukuze zizixube futhi zivikele i-graphite ye-flake. Ngemva kokuxuba, kukhiqizwa isigaba esisha esinesilinganiso sevolumu sesigaba sokuqala.
Okukhulu, okusiza ukuvimba isiteshi sokusabalalisa umoya-mpilo ngaphakathi futhi kwakha isithiyo sokuxilisa umoya-mpilo.
4. Ekushiseni okusebenzayo, inani elikhulu lezinto ezifakiwe njenge-Al2O3, i-SiO2 kanye ne-Fe2O3 ensimbini encibilikisiwe zingamuncwa, ezisabela ngokwazo ku-sinter, ukuze izinto ezihlukahlukene ezifakiwe ezivela ensimbini encibilikisiwe zingene kancane kancane embozweni.
Izinga lokushisa le-oxidation le-flake graphite elikhiqizwa eShayina lingu-560815°C lapho okuqukethwe kwekhabhoni kungu-88%96% kanti usayizi wezinhlayiya ungaphezu kwama-meshes angu-400. Phakathi kwazo, lapho usayizi wezinhlayiya ze-graphite ungu-0.0970.105mm, izinga lokushisa le-oxidation le-graphite elinokuqukethwe kwekhabhoni okungaphezu kuka-90% lingu-600815°C kanti okuqukethwe kwekhabhoni kungaphansi kuka-90%.
Izinga lokushisa le-oxidation likayinki lingu-620790 C. Uma i-crystalline flake graphite ingcono, izinga lokushisa eliphakeme le-oxidation liphakeme, futhi ukulahlekelwa kwesisindo se-oxidation kuncane ekushiseni okuphezulu.
