Ukuze uvimbele ukulimala kokugqwala okubangelwa i-oxidation ye-flake graphite ekushiseni okuphezulu, kuyadingeka ukuthola impahla yokugqoka impahla yokushisa ephezulu, engavikela ngokuphumelelayo i-flake graphite kusuka ku-oxidation ekushiseni okuphezulu. Ukuze sithole lolu hlobo lwejazi le-graphite elilwa ne-oxidation esikalini, kufanele siqale sibe nezici ezithile ezinjengokumelana nezinga lokushisa eliphezulu, ukubumbana okuhle, ukusebenza kahle kokunqanda ukugqwala, ikhono eliqinile lokulwa ne-oxidation nobulukhuni obuphezulu. Umhleli olandelayo we-Furuite Graphite wabelana ngendlela yokuvimbela i-flake graphite ukuthi ifakwe i-oxidized ezingeni lokushisa eliphezulu:
1. Izinto ezinomfutho wesitimu ngaphansi kuka-0.1333MPa(1650℃) kanye nezakhiwo ezinhle ezihlanganisayo ziyamukelwa.
2. Khetha impahla yesigaba sengilazi ehlangabezana nezidingo zokusebenza njengezinto ezizivalayo, futhi ukwenze kube into yokuvala uphawu ngaphakathi kwezinga lokushisa elisebenzayo.
3. Ngokomsebenzi woshintsho wamandla amahhala ajwayelekile okusabela komoya-mpilo nezinga lokushisa, ezingeni lokushisa lokwenza insimbi (1650-1750℃), khetha izinto ezisondelene kakhulu nomoya-mpilo kunekhabhoni-oksijeni, thatha umoya-mpilo kuqala, futhi uzifake oksijini ukuze uzivikele. i-flake graphite. Umthamo wesigaba esisha esikhiqizwe ngemva kwe-oxidation mkhulu kunesigaba sokuqala, esiwusizo ukuvimbela umzila wokusabalalisa ongaphakathi we-oksijeni futhi wenze umgoqo we-oxidation.
4. Emazingeni okushisa okusebenza, ingakwazi ukumunca inani elikhulu lezinto ezifakiwe ezifana ne-AL2O3, SiO2, Fe2O3 ensimbi encibilikisiwe, futhi iphendule ngokwayo ku-sinter, ukuze ukufakwa okuhlukahlukene okuvela ensimbi encibilikisiwe kungene kancane kancane enamathela.
I-Furuite Graphite Xiaobian ikhumbuza ukuthi izinga lokushisa le-oxidation le-flake graphite ezindaweni ezikhiqizayo zase-China ngu-560,815℃ 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-600,815 ℃, kanti lelo le-graphite elinokuqukethwe kwekhabhoni engaphansi kuka-90% lingu-6200℃. Ukuba ngcono kwe-crystalline flake graphite, izinga lokushisa eliphakeme le-oxidation liyakhuphuka kanye nokuncipha kwesisindo se-oxidation ezingeni lokushisa eliphezulu.
