GB/T 33047.3-2021 Plastics—Thermogravimetry (TG) of polymers—Part 3:Determination of the activation energy using the Ozawa-Friedman plot and analysis of the reaction kinetics
Abstract
This document specifies a method of determining the activation energy using the Ozawa-Friedman plot. This document also specifies a method of validating the main curve of reaction kinetics using thermogravimetry.
The Ozawa-Friedman plot (a curve plotting the logarithm of the mass loss rate against the reciprocal of the temperature at which the mass loss occurs) is a differential method that can be applied to thermal analysis with arbitrary temperature changes, such as constant temperature, constant heating rate, sample quantity-controlled thermal analysis, temperature step, and repeated temperature scanning.
