experimental results

All the data were tested by the German Netzsch STA449F5 instrument. Four different heating rates of 5, 10, 20 and 30 K/min were adopted to test the single-component polypropylene, polystyrene, polyvinyl chloride and mixed plastics. Before the experiment, the temperature and sensitivity of the instrument were tested first, and then baseline correction was carried out using blank alumina dry powder. The six plastics were heated from room temperature to 800℃, and the weight loss changes during the plastic combustion process were observed.
