Color changes in wood during heating: kinetic analysis by applying time−temperature superposition method
Résumé
This paper deals with the kinetics of the color of hinoki (Chamaecyparis obtusa Endl.) wood.Specimens cut from the wood were heated at 90-180°C as accelerated aging treatment. The specimens completely dried and heated in the presence of oxygen allowed us to evaluate the effects of thermal oxidation on wood color change. Color properties measured by a spectrophotometer showed similar behavior irrespective of the treatment temperature with each time scale. Kinetic analysis using the time-temperature superposition, principle, which uses the whole data set, was successfully applied to the color changes.
