射流凝固天然橡胶的热降解特性研究

Thermal degradation of natural rubber coagulated by jet

本文用热氧分析研究了射流凝固天然橡胶的热降解行为,结果表明:在N2气氛下,射流凝固天然橡胶的热降解为一步反应;在空气气氛下,射流凝固天然橡胶的热降解行为为三步反应。

Themo gravimetry analysis was utilized to study thermal degradation of NR coagulated by jet. The results showed that the thermal degradation of NR was an one-step reaction under nitrogen;the thermal degradation of NR was a three-step reaction under air atmosphere.
