依兰煤溶胀特性的初步研究

针对依兰煤的溶胀特性进行了初步研究,考察了不同试剂、温度、时间、粒度和浓度等因素对依兰煤溶胀度的影响,并对溶胀煤进行了激光粒度分析和扫描电镜分析。 The principium study was carried out in allusion to the swelling characteristic of Yilan coal,the factors of different solvents,temperature,time,granularity and concentration were reviewed to Yilan swelling ratio,the analysis of laser particle and SEM were carried out to swelling Yilan coal
