摘要
不添加任何氧化剂，采用电化学法用浓硫酸与天然鳞片石墨混合生成可膨胀石墨，其产品膨胀倍数较高，性能较好。对通电时间及电流密度对膨胀倍数的影响作了考察，并对最佳工艺条件进行了讨论。
Expandable Graphite is prepared by the electrochemical method in concentrated Sulfuric acid without any oxidizing agents.The expansion degree of expandable graphite is large,and the results are satisified.Futhermore,the experiment shows that the expansion degree is affected by the reaction time and current indensity,and the optimum conditions are discussed.
