摘要
利用压汞法和图像分析法研究了膨胀石墨的孔结构,压汞法可测量膨胀石墨中微米量级以下的孔隙结构参数,对微米量级以上的孔可以利用图像分析法进行测量,膨胀石墨制备参数对膨胀石墨的孔结构有显著影响,其中插层电量越大孔径尺寸越大,孔径分布越宽;膨化温度越高,孔径尺寸越大,孔径分布也越宽。
The characteristics of porous structure of expanded graphite(EG) were studied by using mercury porosimetry and image analysis. Mercury porosimetry may be. used to measure the porous structure parameters of the pores under the micrometer quantitative level, and the pores over micrometer quantitative level were studied by image analysis. The processing, parameters have an important influence on the porous structure of EG, the more electricity consumption used, the larger pore size and the broader distribution of the pore size; on the other hand, the higher expanding temperature, the larger pore size and the broader distribution of the pore size.
