摘要
以蛇纹石尾矿为主要原料,抛光砖废料为发泡剂、再辅以低温砂、滑石、膨润土等原料制备发泡陶瓷。实验研究了配方组成、烧成温度等因素对发泡陶瓷材料性能的影响。结果表明:当蛇纹石尾矿45wt.%、低温砂43wt.%、滑石7wt.%、膨润土5wt.%、抛光砖废料外加量为10wt.%,烧成温度1150℃、保温时间15min的条件下,可以制备出综合性能良好的发泡陶瓷材料,其体积密度为0.66g/cm3、抗压强度为7.22MPa,能够满足使用性能的要求。
A foamed ceramic was prepared using serpentine tailings as the main raw material,the wastes of the polished tile as the foaming agent,and low temperature sand,talc and bentonite as supplements.The influence of the batch formula and the firing temperature on the properties of the foamed ceramic was studied.The results show that the foamed ceramic with good performances may be obtained with 45wt.% serpentine tailings,43wt.% low-temperature sand,7wt.% talc,5wt.% bentonite,and 10wt.% polished-tile wastes,when fired at 1150℃ and heat soakced for 15min.The bulk density and compressive strength of the foamed ceramic are 0.66g/cm3 and 7.22MPa,respectively,satisfying the requirements for application.
