       可膨脹石墨
       又稱酸化石墨，以80 目以上規格大片鱗片石墨為原料，采用氧化插層工藝將硫酸等插層劑插入到石墨片層間形成的石墨插層化合物。可膨脹石墨中的插層劑在800~1000℃高溫下會迅速分解拉開石墨片層，形成具有多孔結構的蠕蟲狀膨脹石墨。

       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.

       產品性能
       可膨脹石墨含碳量生產范圍在85%-99.9%，膨脹率通過調整原料和插層劑插層程度可以控制膨脹率為150~350 倍。膨化后具有多孔結構，比表面積高。

       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
       可膨脹石墨是制備柔性石墨、膨脹石墨細粉的原料，也被用于隱身材料、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.
