【摘要】 以煤油为介质测量膨胀石墨的表观密度，由所测密度值与浸泡时间的关系得出膨胀石墨对煤油的吸附吸收量随时间的变化曲线，并导出膨胀石墨最终表观密度、开放孔孔隙率和封闭孔孔隙率。更多还原

【Abstract】 The apparent density of expanded graphite was measured by gravity bottle method and by taking kerosene as the medium.From the changes of apparent density with soaking time,the curve of adsorbed amount of kerosene in expanded graphite was plotted against soaking time and the final apparent density the porosity of open pores and the porosity of closed pores in expanded graphite wereobtained.更多还原
