Abstract
Eucalyptus wood samples are impregnated with 5 and 15% concentration of ammonium dihydrogen phosphate (ADP) flame retardant, for three impregnation times (1, 3 and 5 h). These impregnated samples along with un-impregnated eucalyptus wood are analysed using thermal analysis technique, and thermal decomposition parameters are measured. Further, activation energy of these samples, for each stage of decomposition, are determined by employing different kinetic models namely Horowitz and Metzger, Broido, Coats and Redfern and Ozawa–Flynn–Wall. The results based on these models show that the activation energy of impregnated wood samples decreases with increase of ADP concentration and impregnation time. Finally, the wood samples are analysed through scanning electron microscopy to glimpse the surface morphology.
