摘 要: 膨胀石墨具有耐高温、耐腐蚀、抗氧化、压缩性好等优点,在众多领域有着广泛的应用.作者研究了膨胀温度和膨胀时间对膨胀容积的影响,并用扫描电镜(SEM)对膨胀石墨的结构进行了分析.研究表明:温度在900℃,膨胀时间为30~50 s时,可膨胀石墨能发生良好的膨胀效果;膨胀石墨具有发达的孔隙结构,孔径尺寸在微米级,大小不一. Expanded graphite has been widely used as a novel material with its excellent properties.The article studied on the production and structure of expanded graphite.SEM photos showed that the surface of flexible graphite had numerous holes in size μm-level,which give expanded graphite well compressibility.The expanded temperauure of expanded graphite produced was 900 ℃,and the expanded time was 30~50 s.
