Interaction of the Components of Wood and High Temperatures during Pressing of Wood Composites and its Effect on the Formation of Composites Avoiding the Chemical Changes in Composition of Pressed Wood Particles and Elimination of the Fire Risk

In the process of wood composites pressing, the temperature and moisture changes of the interaction of wood particles and glue are created. The project will solve the effect of high temperature of wood composites pressing to non-stationary temperature and moisture fields in pressed materials by mathematics and physics methods and it will solve the identification of the impact of high of temperatures, moisture and heat transfer rate and the impact of adhesive during pressing to the creation of the risk of irreversible chemical changes in composition of pressed particles associated with possible initiation of fire. Modeling of these complex relationships for the determination of the maximum possible temperatures of pressing composites will enable the numerical solution of the distribution and the maximum level of pressing temperatures in composites in the safety zone without the risk of fire ignition and also to predict the creation of chemical changes in particles and thus to control the process of pressing.
