Ukuze kuvinjelwe umonakalo wokugqwala obangelwa ukugqwala kwe-flake graphite ekushiseni okuphezulu, kuyadingeka ukuthola into yokumboza into yokushisa okuphezulu, engavikela ngempumelelo i-flake graphite ekugqwaleni ekushiseni okuphezulu. Ukuze sithole lolu hlobo lwe-scale graphite anti-oxidation coat, kumele kuqala sibe nezici ezithile ezifana nokumelana nokushisa okuphezulu, ukuqina okuhle, ukusebenza okuhle kokulwa nokugqwala, ikhono eliqinile lokulwa nokugqwala kanye nokuqina okuphezulu. Umhleli olandelayo we-Furuite Graphite wabelana ngendlela yokuvimbela i-flake graphite ekugqwaleni ekushiseni okuphezulu:
1. Izinto ezinomfutho womusi ongaphansi kuka-0.1333MPa(1650℃) kanye nezakhiwo ezinhle eziphelele ziyasetshenziswa.
2. Khetha izinto zesigaba sengilazi ezihlangabezana nezidingo zokusebenza njengento ezivala yona, bese uzenza zibe izinto zokuvala eziqhekekile ngaphakathi kwezinga lokushisa lokusebenza.
3. Ngokusho komsebenzi wokushintsha kwamandla akhululekile ajwayelekile okusabela nomoya-mpilo kanye nokushisa, ekushiseni kokwenza insimbi (1650-1750℃), khetha izinto ezihambisana nomoya-mpilo kakhulu kune-carbon-oxygen, zibambe umoya-mpilo kuqala, bese zizixuba ukuze zivikele i-graphite ye-flake. Umthamo wesigaba esisha esikhiqizwa ngemva kokushisa mkhulu kunowesigaba sokuqala, okuwusizo ukuvimba isiteshi sokusabalalisa umoya-mpilo ngaphakathi futhi kwakhiwe isithiyo sokushisa umoya-mpilo.
4. Lapho izinga lokushisa lisebenza, lingamunca inani elikhulu lezinto ezifakiwe njenge-AL2O3, i-SiO2, i-Fe2O3 ngensimbi encibilikisiwe, bese lisabela ngokwalo ku-sinter, ukuze izinto ezahlukahlukene ezifakiwe ezivela ensimbini encibilikisiwe zingene kancane kancane embozweni.
I-Furuite Graphite Xiaobian ikhumbuza ukuthi izinga lokushisa lokushiswa kwe-flake graphite ezindaweni ezikhiqiza kakhulu zaseShayina lingu-560,815℃ lapho okuqukethwe kwekhabhoni kungu-88%96% kanti usayizi wezinhlayiya ungaphezu kwe-mesh engu--400. Phakathi kwazo, lapho usayizi wezinhlayiya ze-graphite ungu-0.0970.105mm, izinga lokushisa lokushiswa kwe-graphite enokuqukethwe kwekhabhoni okungaphezu kuka-90% lingu-600,815℃, kanti ele-graphite enokuqukethwe kwekhabhoni okungaphansi kuka-90% lingu-6200℃. Uma i-crystalline flake graphite ingcono, izinga lokushisa eliphakeme lokushiswa kwe-oxidation liyanda futhi kuncipha ukulahlekelwa kwesisindo se-oxidation lapho kushisa kakhulu.
