Pyrolysis process of four common PVC decoration materials in the construction and decoration materials market , the selected PVC sheet , PVC plastic steel , PVC pinch , PVC casing four PVC decoration materials , thermal gravimetric analysis technology , respectively, in 5 ℃ / min, 10 ℃ / min, 15 ℃ / min thermal analysis experiments three different heating rates of four kinds of PVC decoration materials . TG curve analysis , in-depth understanding of the process of PVC decoration materials varies with temperature and heating rate on the pyrolysis process , the the PVC material pyrolysis process is divided into three main stages of weightlessness , evident from the DTG curves be seen that the three stages of the performance of the three peaks . PVC decoration materials of different temperature ranges Coast - Redfern integral method for solving the kinetic parameters obtained four PVC samples at different heating rates under different temperature ranges pyrolysis parameters are 0-2 , and through the integration method backstepping Law verify the correctness of the kinetic parameters of pyrolysis is the initial stage of the fire , prevention and treatment of the fire is the most effective method is to control the early stages of the fire , thermal analysis experiments commonly used PVC construction and decoration materials , master the thermal decomposition mechanism and the kinetic parameters , in-depth understanding of the thermal stability of PVC material and ignition characteristics for effective control of fire occurrence and development of great significance .
