摘要
研究了活性石灰的微观结构与活性度的关系。在AutoPore IV 9500型压汞仪上对样品进行孔隙结构分析,在场发射扫描电子显微镜下观察样品的微观形貌,通过国标法测了试样品活性度。实验发现:随着比表面积、孔容积的增大,石灰活性度增大;随着平均孔径的增加,石灰的活性度下降。
We study relationship between microstructure and activity of lime. The lime be tested in AutoPore 1V 9500. to find out characteristics of pore structure. Using emission scanning electron microscope observe the morpholog）＂ of the samples. We measured the activity of the test samples through the GB. The study showed that lime degree of activity increases, with the specific surface area increasing and with pore volume increasing, lime activity is rising with the decreasing of average pore diameter.
