摘要
采用热重分析仪(TGA)在氮气保护下研究了高密度聚乙烯(HDPE)及HDPE/硫酸钙粉体复合材料的热分解行为,并分别运用Kissinger法和Flynn-Wall-Ozawa法计算了它们的活化能。结果表明:基于这2种计算方法,HDPE/硫酸钙粉体复合材料的热分解活化能相比纯的HDPE提高了44.37%和69.31%。
Thermal degradation behavior of HDPE and HDPE/calcium sulphate composites in N2-ambient was investigated by using TGA, and activation energy of thermal decomposition of the HDPE and the HDPE/calcium sulphate composites was evaluated by using Kissinger method and Flynn-Wall-Ozawa method respectively. The results show that based on Kissingger and Flynn-Wall-Ozawa method, the activation energy of the HDPE/calcium sulphate composites increases by 44.37%and 69.31% compared with HDPE.
