Özet
The aim of this study was to investigate the role of the panel density and solid content of adhesive on the physical (thickness swelling) and mechanical properties (modulus of rupture, modulus of elasticity, and internal bonding strength) of particleboard composite. For the changing panel density, two different target densities (0.60 and 0.65 g/cm(3)), three different hot pressing pressures (20, 25, and 30 kg/cm(2)), two different shelling ratios (35% and 45%), and two different surface coating materials (at 70 and 90 g/m(2) grammage) were applied during the manufacturing of test panels. Increasing pressure improved all the properties of particleboard. However, applying lower or higher pressure level than required and necessary level negatively affected the thickness of the panels. Shelling ratio was found to be effective on the mechanical and physical properties of particleboard. Increasing panel density improved the strength properties and thickness swelling after 2 h immersion. However, high panel density negatively affected the thickness swelling after 24 h immersion. Coating of particleboard surfaces caused superior mechanical, except for internal bond strength, and physical properties. Melamine-impregnated paper grammage significantly improved the modulus of rupture, modulus of elasticity, and thickness swelling. Increasing paper grammage improved these properties. However, internal bond strength was not affected by paper grammage. Decreasing solid content of adhesive in the surface layers significantly improved all the properties of particleboard composite.
