酚醛树脂热解高斯分峰法

为了准确描述酚醛树脂热解时相互重叠的反应过程,进行了5种线性升温速率下的酚醛树脂热分析试验,提出一种高斯分峰方法。该方法通过分析酚醛树脂的微分热重(DTG)曲线以及不同温度下热分解产物的种类和含量,将酚醛树脂热解划分为四个反应过程。分峰结果与试验结果吻合较好,对后续准确求解酚醛树脂各个反应过程热分解动力学参数有重要意义。

Gaussian Peak Separation Method for Thermal Decomposition of Phenolic Resin

In order to accurately model the overlapping pyrolysis reactions of phenolic resin, thermal analysis experiment

with phenolic resin under five constant linear heating rates is conducted, and a Gaussian peak separation

method is proposed. In this method, through the analysis of the differential thermogravimetric (DTG) curves of phenolic

resin and the types and contents of the thermal decomposition products at different temperatures, the pyrolysis

reactions of phenolic resin are divided into four. The results of peak separation are in good agreement with the experiments,

which has important significance on the true determination of the kinetic parameters for the thermal decomposition

of phenolic resin.
