摘要
研究了粉煤灰经过机械研磨后的热学性质的变化。不同的机械研磨方式 ,粉煤灰的热学性质表现不一样 ;对于同一种机械研磨方式 ,不同粉煤灰的热学性质有一些共同之处。粉煤灰机械处理之后热学活性的增加 ,机械热效应在研磨中起重要作用。DTA峰温的提前 ,实质是粉煤灰颗粒在机械能的作用下位能升高 。
The thermal characters of fly ash ground by machine are studied.Different thermal characters correspond to different mechanical grindig way.As to teh same ind of grinding way,the thermal characters of different fly ashes have something in common.The increasing of thermal activities of fly ash treated by mechanical grinding largely attributes to the thermal results of grinding.The DTA peak temperatures are earlier than original grinding essentially due to the potential energy of ground fly ash is raised and instability of fly ash is increased.
