Thermogravimetric analysis description

It is shown that the applicability of fractal model of anomalous diffusion for quantitative description of thermogravimetric analysis results in case of high density polyethylene modified by high disperse mixture Fe/FeO (Z). It is shown the influence of diffusion type on the value of sample 5%-th mass loss temperature and was offered structural analysis of this effect. The critical content Z it is determined, at which degradation will be elapse so, as in inert gas atmosphere.

Thermogravimetric measurements were made with thermoanalytical set. The detail description of the equipment, procedures of the measurements and software for treatment of the experimental data and calculations of uncertainties were reported earlier [3], The chemical analysis of content of C,N,H was performed with CHNS-0 Analyzer Flash TF 1112 Series.
