Effect of Paulownia wood particles addition and press time on particleboard surface quality

The objective of this study was to examine the effect of Paulownia particles addition and pressing time on the surface quality of particleboard made. In this regard, Paulownia chips and industrial chips were used in surface and core layers, respectively. Urea-formaldehyde resin was applied at 12% fo...
