| Abstract: | The contents of Polystyrene(PS)and CaCO3 in package materials were determined mainly by TGA.The orthogonal design was applied and a systematic study of the conditional experiments was carried out,suth as the influence of different heating rates,sample weights,gas flow rates and their interactions on the determination results.A rapid,accurate,convenient and low dosage optimal TGA method was put forward.And the stability index of the experiment was calculated so as to provide a theoretical and experimental basis for the quality-control in the production of such kind of PS/CaCO3 package materials. |
