摘要
本文借助于电子计算机,用动态热重分析(TG)力学。得出了聚甲醛在空气和氮气中热降解反应级数、同温度下的使用寿命。法研究了聚甲醛(POM)热降解反应的动活化能和频率因子。
In this study the thermal degradation kinetics of Polyoxymethylene (POM) has been investigated using a dynamic TG technique with the aid of computer. Both in air and nitrogen the values of degradation reaction order, activation energy and frequency factor were obtained and lifetime was estimated at various temperature.
