“…The ratio of panel density and the wood density determines the compaction rate (CR). In general, the higher compaction rate results in highest strength and stiffness of the panel (TRIANOSKI et al, 2013;SOZIM et al, 2019).…”

This study aimed to verify technical potential of using waste from wood veneers and plywood as a raw material for the production of MDP. The variance analysis of the panels density was carried out. Physical-mechanical properties were evaluated by comparing them with the international standards and by analysis of variance. The averages were subjected to the analysis of covariance, at the level of 5% probability. Finally, Pearson's correlation analysis between properties was performed. The panels produced with "log core" and "veneer clippings" residues showed equivalent averages for physical properties and higher for mechanical properties of internal bond and surface screw withdrawal, when compared the averages of panels produced with commercial particles. Panels produced with "plywood cutting" showed unsatisfactory mechanical properties. It's concluded that the "log core" and "veneer clippings" residues show potential for use as a raw material in the composition of MDP.

The objective of this work was to evaluate the physical-mechanical properties and the density profile of panels produced with sugarcane bagasse particles with two sizes (0.50 and 0.85 mm) and with pre-treatment (particles treated in hot water at 70 °C for two hours) and without pre-treatment. The nominal density of the panels was 0.65 g cm -3 . The cycle parameters were 35 kgf cm -2 of pressure, temperature of 180 °C and 10 min of pressing. The physical and mechanical tests were performed according to the requirements of NBR 14810-2006. The density profile of the particleboards was obtained by X-ray densitometry. The water absorption in two hours was higher in the panels produced with particles treated in hot water. The other physical and mechanical properties were not influenced by the evaluated factors. The apparent density varied along the thickness of the panels, with more pronounced peaks in the outer layers, thus presenting a vertical density gradient within the normal range for this type of panel. The physical-mechanical properties do not meet the minimum requirements by the NBR 14810 ( 2006) for nonstructural panels for indoor use in dry conditions (Type P2).

“…In Brazil, several alternative species for the production of particleboard have already been researched, such as Schizolobium amazonicum and Cecropia hololeuca (Iwakiri et al, 2010); Cryptomeria japonica (Trianoski et al, 2013); Toona ciliata (Trianoski et al, 2014); Hovenia dulcis and Mimosa scabrella (Sanches et al, 2016); Pinus patula (Rios et al, 2016); Eucalyptus badjensis (Pereira et al, 2017); Hevea brasiliensis (Iwakiri et al, 2018); Ligustrum lucidum (Sozim et al, 2019); Cupressus torulosa (Iwakiri et al, 2020).…”

Use of Populus deltoides wood in the Production of MDP and HDP

2021

View full text Add to dashboard Cite

The aimed to evaluate the properties of MDP and HDP panels, produced with pure Populus deltoides or in a mixture with Pinus taeda, together with urea-formaldehyde resin. The density and chemical properties of this wood with 8 and 12 years of age were determined, which were used for the production of panels with nominal density of 0.65 and 0.90 g.cm -3 . Water absorption and thickness swelling tests were performed after 2 and 24 hours of immersion, as well as static bending and perpendicular tensile. Populus deltoides wood was classified as low-density in both ages and presented chemical properties similar to Pinus taeda. Mechanical properties obtained for the panels produced reached the minimum requirements values established by the standards NBR 14810-2 and ANSI A208.1, demonstrating the potential use of wood species for the production of MDP and HDP panels, at both ages studied and used pure or mixed with Pinus taeda wood.
