可膨胀石墨
       又称酸化石墨，以80 目以上规格大片鳞片石墨为原料，采用氧化插层工艺将硫酸等插层剂插入到石墨片层间形成的石墨插层化合物。可膨胀石墨中的插层剂在800~1000℃高温下会迅速分解拉开石墨片层，形成具有多孔结构的蠕虫状膨胀石墨。

       Expandable Graphite
       Expandable Graphite also called acid graphite,use large flake graphite ofmore than 80 mesh as raw materials,with the oxidation intercalation process,inserting the of sulphuric acid and sulfate ion into graphite layers,formed intoGraphite intercalation compounds.Intercalation agent at the temperature of800~1000 ℃,it will decompose rapidly, produce gas to opengraphite sheets,finally, forming the Wormlike expandablegraphite with vesicular structure.

       产品性能
       可膨胀石墨含碳量生产范围在85%-99.9%，膨胀率通过调整原料和插层剂插层程度可以控制膨胀率为150~350 倍。膨化后具有多孔结构，比表面积高。

       Product Performance
       High expansion ratio, with adjusting the raw materials and the intercalating agent, expansion rate could be 150~350 times,it hasvesicular structure, high specific surface area

       主要用途
       可膨胀石墨是制备柔性石墨、膨胀石墨细粉的原料，也被用于隐身材料、阻燃材料等。
       Main Applications
       Expandable graphite is raw materials for preparation of flexible graphite, expanded graphite powde, it could also be used for stealth materials, flameretardant materials etc.
