Modelling and Optimisation of MDF Hot Pressing: Mathematical Model to Predict the Impact of Initial Parameters on the Final Properties of MDF Board

The present computer model attempts a more complete integration than in previous published models of all the components such as heat transfer, moisture movement and vertical density profile formation in a one-dimensional model of hot pressing of MDF. The model can predict properties of a pressed board for the standard manufacturing conditions and also the new hot pressing technologies such as the use of steam injection or a cooling zone in the continuous press. The present model will become an important tool in the hands of wood technologists, process engineers and MDF manufacturing personnel, to better understand the internal processes and to improve production and quality of wood composite boards.
