石灰石活化分解的研究

Study on limestone activation and decomposition

以某水泥厂不同产地(A矿山石灰石和B矿山石灰石)的石灰石为原料,用XRD、TG-DTA测试方法对其相关特性进行了分析;并运用石灰石分解的相边界反应收缩圆柱体反应机理,对其进行了石灰石分解活化能计算分析。结果显示A矿山石灰石较B矿山石灰石的活化能低、易分解。

By taking the limestone from different quarry （A and B） as an example, the author made related analysis in XRD and TG-DTA methods; An analysis on limestone decomposition activating energy by using the principle of phase boundary contraction cylinder reaction was made. The results show that CaCO3 content of limestone from Quarry A is higher than that from Quarry B; its activating energy is low and easy to decompose.
