“…There are no comparative values available in the literature for water absorption and thickness swelling for structural particleboards produced with resin moisture resistant. However, the mean values of TS 24 h obtained in this study were lower than the results reported by some researchers to pine boards produced with urea-formaldehyde resin: 18.61% (Trianoski et al, 2013); 24.22% (Iwakiri et al, 2014); 31.41% (Trianoski et al, 2016); 18.56% (Trianoski et al, 2011).…”

“…All treatments met the minimum values of 800 N and 1,020 N, respectively for the RAP-T and RAP-S, as established by the ABNT-NBR 14810-2:2006. Although the comparative figures are not available in the literature for mechanical properties of structural particleboards produced with moisture resistant resin, the results obtained in this study were satisfactory in comparison to those presented by some researchers to pine boards produced with urea-formaldehyde resin. For the MOE, the values referenced were 1,581 MPa (Trianoski et al, 2011), 1,751 MPa (Trianoski et al, 2011) and 1,847 MPa (Iwakiri et al, 2014). For MOR the values were 11.17 MPa (Trianoski et al, 2011), 13.94 MPa (Trianoski et al, 2016) and 12.78 MPa (Iwakiri et al, 2014).…”

The objective of this work was to evaluate the feasibility of using lignin-phenol-formaldehyde resin in the production of Mimosa scabrella Benth (bracatinga) structural particleboard. The boards were produced with nominal specific mass of 0.75 and 0.95 g/cm3, 10% and 12% of phenol-formaldehyde and lignin-phenol-formaldehyde resins, with 10 and 12 min of pressing time. The boards quality was evaluated by means of the following physical-mechanical tests: specific mass, compression ratio, water absorption and thickness swelling after 2 and 24 hours soaking, perpendicular traction, static bending and screw pulling. Positive interactions of specific mass, resin content and pressing time were observed in the properties of the boards produced. The evaluation of the properties results based on the requirements of EN 312 (type P5) standard indicated the feasibility of using lignin-phenol-formaldehyde resin in the production of particleboard of Mimosa scabrellla for structural applications.

“…Iwakiri et al 21 have evaluated the physical and mechanical properties of particleboard panels manufactured with wood particles from Sequoia sempervirens and Pinus taeda combined with urea-formaldehyde resin (UF), using different mixing ratios. The findings achieved for internal bond, modulus of elasticity (MOE) and modulus of rupture (MOR) under static bending have met the minimum requirements of British Standard BS312:2003 in all treatments, revealing that Sequoia sempervirens has great potential for particleboard production 21 . In order to combine the mechanical performance of Pinus taeda and Sugarcane bagasse, hot-pressed hybrid sandwich particleboard panels were investigated in this work.…”

A multilayer particleboard panels, consisted of sugarcane bagasse reinforced composite as core material and hybrid composites made with Pinus taeda particles and Malva fibres as facing materials, were designed and evaluated in this work. Tukey test was used to identify the effect of the facing material, considering different combinations of Pinus taeda particles and Malva fibres, on the bulk density, thickness swelling, flexural strength, flexural stiffness and X-ray densitometry. A spray-up process was used to spread castor oil based polyurethane resin upon the dispersive phases followed by a hot compaction at 100 o C. The particleboards were classified as medium density panels in accordance to the Brazilian, American and Canadian Standards. All treatments reached the minimum strength except for elastic modulus. Tukey test demonstrated the flexural strength and modulus responses for all treatments were statistically similar. Hybrid particleboard consisted of 75% of Pinus taeda wood and 25% of Malva fibres revealed a promising sustainable material for furniture industries, combining strength, low-cost and lower thickness swelling values.

“…This seemed to happen because of the spread over of resin to a greater particle surface area instead of filling the voids existence inbetween the particles. According to [25], board with higher compaction ratio tends to have a more closed structure. As shown in Figure 4, TS of particleboards increased significantly with increasing board density.…”

The aim of this study was to investigate the role of the particle size, board density, resin content and hot press temperature on the properties of particleboard composite. Single-layered Kelempayan (Neolamarckia cadamba) particleboards bonded with phenol formaldehyde (PF) resins were manufactured. The boards were fabricated with three different particle sizes (0.5, 1.0 and 2.0 mm), two different board densities (600 and 700 kgm -3 ), two different resin contents (9 and 11%) and two different hot press temperatures (155 and 165˚C). The boards produced were evaluated for their modulus of elasticity (MOE), modulus of rupture (MOR), internal bond (IB) and thickness swelling (TS) in accordance with the Malaysia Standards. The study revealed that boards from smaller particles, higher resin contents and higher hot press temperatures gave higher MOE, MOR, IB and improved the TS. However, boards with higher densities gave higher MOE, MOR, IB and TS. Overall, the boards with the particle size of 0.5 mm, board density of 700 kgm -3 , resin content of 11% and 165˚C of hot press temperature exhibited the greatest performance and were able to fulfill the Malaysia Standard specifications for furniture grade used in dry (PF1) and humid (PF2) and also for load-bearing applications in dry (PS1).
