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 simelane nezinga lokushisa eliphezulu nokuhlangana.
Kuhle, ukumelana nokugqwala okuhle, ukumelana ne-oxidation okuqinile, ubulukhuni obuphezulu nezinye izici. I-Furuite Graphite Xiaobian elandelayo yethula izindlela zokuvimbela i-flake graphite ukuthi ifakwe i-oxidized ezingeni lokushisa eliphezulu:
1. Sebenzisa izinto ezinomfutho we-vapor ongaphansi kuka-0.1333MPa(1650*C) kanye nokusebenza okuhle okuphelele.
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 komoya-mpilo ngezinga lokushisa, ekushiseni kwensimbi (1650-1750*C), izinto ezihambisana kakhulu nomoya-mpilo kune-carbon-oksijeni zikhethwa ukuze zibambe umoya-mpilo, ngakho-ke. ukuze bazifake oxidize futhi bavikele i-flake graphite. Ngemuva kwe-oxidation, isigaba esisha esinesilinganiso sevolumu sesigaba sokuqala siyakhiqizwa.
Okukhulu, okuwusizo ukuvimba umgudu wokusabalalisa ongaphakathi womoya-mpilo futhi kwakha 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.
Izinga lokushisa le-oxidation le-flake graphite elikhiqizwa eShayina lingu-560815°C lapho okuqukethwe kwekhabhoni kungu-88%96% futhi usayizi wezinhlayiyana ungaphezu kwama-meshes angu-400. Phakathi kwazo, lapho usayizi wezinhlayiyana zegraphite ungu-0.0970.105mm, izinga lokushisa le-oxidation le-graphite elinokuqukethwe kwekhabhoni engaphezu kuka-90% lingu-600815 ° C kanti okuqukethwe kwekhabhoni kungaphansi kuka-90%.
Izinga lokushisa le-oxidation likayinki lingu-620790 C. I-crystalline flake graphite engcono kakhulu, izinga lokushisa eliphakeme le-oxidation liphezulu, futhi ukuncipha kwesisindo se-oxidation kuba sezingeni eliphezulu lokushisa.
