Thermal gravimetric analysis (TGA) of several common plastics (polypropylene, polyethylene, polyvinyl chloride, polystyrene) pyrolysis weightlessness and its dynamics law were studied. Experiment heating rate of 10 ℃ / min, a final temperature of 600 ℃, pyrolysis under a nitrogen atmosphere. According to the basic experimental data obtained in TGA experiments using CR method and obtained several common law MKN plastic reaction order n, the activation energy E and frequency factor A. The results showed that: polypropylene, polyethylene, polystyrene, a thermal decomposition stage is completed, the PVC is thermally decomposed in two stages, and the pyrolysis reactions are a reaction.追问按照科技论文的方式翻译
