Kinetics of PVC Isothermal Combustion
Abstract:
The burning behavior of 3 mm-thick PVC slabs(100 mm×100 mm) at different temperatures was studied with a cone calorimeter.A single equation model of mass loss rate vs time was simulated with a chemical kinetic method.The fitted results suggest that for PVC burning within a temperature range of 674~(892℃),the reacting kinetic equation can be described as-ln(1-a)=Ae-E/RTt;where the pre-exponential factor A and the average activation energy E are about 0.725 7 s-1and 45.2 kJ/mol,respectively.The simulation results are in reasonably good agreement with the experimental data.In the combustion process of PVC,the oxidation of hydrocarbon is the main oxygen consumption reaction,and the products are CO2 and CO,whose yields are both independent of the reaction temperature.
