“…These studies have been effective in optimizing the production process and improving the mechanical properties of veneer panels. In addition to this, Demir Aydin and Aydin Ismail have found that the surface bonding strength of veneer panels is closely related to the contact angle and surface free energy of the veneer [ 16 ]. Veneers with lower contact angles and smoother surfaces have higher surface free energy values, and plywood made from veneers with higher surface free energy tends to have higher bonding strength.…”

In order to improve the decorative properties of Magnesium-Glass-Board (MGB), the surface morphology and decoration performance of MGB, are studied in detail by using profilometer, microscope and SEM, and the influence of its characterization, such as surface roughness, surface porosity and wettability, on decorative properties of MGB is analyzed by comparing with medium density fiberboard (MDF) and medium density particleboard (MDP). The results first showed that the surface of MGB has a porous structure, but MDF and MDP are not, resulting in a poor decorative performance of MGB. Second, it is found that the surface wettability of MGB is better than others. Third, the hot-pressing parameters including pressure, temperature and time have different influence on decorative performance of MGB during hot-pressing experiment. Finally, the surface bonding strength is positively correlated with pressure, but not with temperature and time. In general, a higher surface bonding strength led to a better decorative performance of MGB. The furthermore research can concentrate on the modification method of the MGB’s surface according to this paper’s conclusion to improve the lamination performance of melamine paper.

This work evaluated the influence of impregnation of boron compounds, in three concentrations, on Pinus sp. veneers, and its effect on the properties of plywood. The experiment was carried out in a completely randomized design, in a 3 × 3 + 1 factorial scheme, with three boron compounds (boric acid, borax, and disodium octaborate tetrahydrate) and three solution concentrations (1%, 3%, and 5%) plus the control. The panels were produced with three or five veneers, depending on the test, impregnated by dipping in boron compound solutions for 15 min and bonded with urea-formaldehyde adhesive. The apparent density, water absorption, thickness expansion, hygroscopicity, resistance to static bending (parallel and perpendicular to the grain) and shear strength were evaluted. All tests were carried out following the European Committee for Standardization, and the results were compared to the Brazilian Association of Mechanically Processed Wood requirements. Based on the results, it is recommended to use boric acid at a concentration of 1% or 3% or the other compounds tested at a concentration of 1%.
