摘要
以湖南益阳某矿山的页岩为研究对象,在地质调查基础上,通过XRD分析、TG-DSC分析确定了页岩陶粒的基本特征;用高温润湿角测定仪、箱式电炉确定了陶粒页岩的发生膨胀的温度范围;分析了保温时间、升温速率等因素对陶粒页岩膨胀的影响;获得了该页岩理想的烧成制度。在实验室研究的基础上组织了两次工业级中试试验,获得了各项指标均达到GBT17431.2-2010标准要求的页岩陶粒产品。
Taking the shale in a certain mine of Hunan Yiyang as the object of study, the basic characteristics of the Shale is determined through the means of XRD analysis and TG-DSC curve analysis. The range of haydite shale expansion temperature is identified by high-tem- perature wetting angle detector and energy-saving box-type furnace. The impact of the holding time, heating rate on the expansion of haydite shale is analyzed. And the ideal firing system is gotten. All targets of the ceramsite getting from twice pilot experiment were achieved the standard of GBT17431.2-2010.
