THE EFFECT OF HEAT ON WOOD ACIDITY IN PARTICLEBOARD PROCESS

In order to investigate the influence of processing variables such as particle drying temperature, press temperature and hardner consumption on wood acidity and bonding performance of UF resin, experimental boards were produced using beech wood particle, drying temperature varied at 80, 110 and 140°...
