“恒速反应”热重分析法用于测定非等温热分解的动力学参数(英)

Determination of Kinetic Parameters of Non-isothermal Decomposition by "Constant Reaction Rate" Thermogravimetric Analysis

利用高解析热重分析仪提出了一种简单可靠的方法，用以测定固体非等温热分解反应的动力学参数．以EVA的第1阶段热裂解为例，说明测定表观活化能、频率因子以及确定最合适反应机理函数的实验和数据处理方法．所得结果与传统热失重法数据一致．

A simple method to determine the apparent activation energy, frequency factor and the mechanism function of a non - isothermal degradation of solid reaction is introduced by using 'constant reaction rate' approach of a thermogravimetric analyzer (CRRTGA).
