煤矸石轻质保温砖的导热性能研究

RESEARCH ON THE PROPERTY OF HEAT TRANSMISSION OF LIGHT WEIGHT COAL REFUSE THERMAL INSULATION MATERIAL

以煤矸石为主要原料研制轻质保温砖,是煤矸石资源化综合利用的新途径。通过对煤矸石轻质保温砖导热机理的分析,研究了材料的物相组成及气孔率、煤矸石掺入量以及烧成温度制度等因素对其导热性能的影响。实验结果表明,煤矸石轻质保温砖具有较低的导热系数,与其制备的工艺参数有关,也与其物相组成和结构有关。

Development of lignt weight thermal insulation material from coal refuse as a main raw material is a new way for the comprehensive utilization of coal refuse. By analysing the mechanism of thermal conduction of light weight coal refuse thermal insulation material, the influence factors are studied in this paper, such as substanse phase composition, porosity, content of coal refuse and sintering temperature regulation of the material on the property of heat transmission. The results of experiments prove that the thermal insulation material possesses low thermal conductivity, which are related to the technological parameters in production and composition-structure of substanse phase.
