Some of the Physical and Mechanical Properties of Particleboard Made from Betung Bamboo (Dendrocalamus asper)

Abstract

The objective of this study was to evaluate various physical and mechanical properties of experimental particleboard panels made from Asian giant bamboo (Dendrocalamus asper). Single layer panels having a density level of 0.75 g/cm3 from coarse and fine particles were used within the scope of this study. Thickness swelling, water absorption, surface roughness, and wettability characteristics of the samples were tested as physical properties while bending, internal bond strength, and screw withdrawal strength of the panels were considered for their mechanical properties. Resistance of the panels against termite and fungus were also determined. Based on the findings in the work both physical and mechanical properties of the panels made from coarse particles resulted in higher values than those made from fine particles with the exception of their internal bond strength. It appears that using fine particles in the panels enhanced their overall surface quality as well as wettability. Regarding biological deterioration of the samples, those made with coarse particles had better resistance. It seems that giant bamboo as a non-wood lignocellulosic species would have potential to be used as raw material to the manufacture value added particleboard with accepted characteristics.

Sieving and hydrothermal pre‐treatments for preparing ultra‐high mechanical strength particleboard

“…Many straw‐based particleboards with weak bonding strength were owing to the low rigidity of materials, which was usually blended with wood particles to improve the strength 17 . MOR and IBS of RPs were obviously higher than those of many other non‐wood‐based particleboards and even particleboards made from wood 30–33 . The mechanical strength of particleboards is not only affected by the structure of biomass, but also by the formation process.…”

Interaction between particle size and mixing ratio on porosity and properties of tea oil camellia (Camellia oleifera Abel.) shells-based particleboard

“…In the case of group A, even though particleboard with fine particles had higher density, the ESW was lower than particleboard with coarse particles. The recorded FSW in group C was 693 to 1079 N and the ESW was 1665 to 2394 N. As a result, it can be concluded that particle size is an important parameter in single layer particleboard to achieve the properties desired for specific applications [19].…”

“…Particles with a high aspect ratio (Length/Thickness) provide a larger surface area for adhesive contact, and besides, particles with a low aspect ratio and small size serve as fillers to fill the void between larger particles [18]. The effect of particle size on particleboard has been extensively studied; recently Karlinasari et al and Bazzetto et al reported coarse particles could have better physical and mechanical properties compared to fine particles in the production of single-layer particleboard with bamboo, however, analysis of IB has shown fine particles are better at bonding due to their vast surface area [19,20]. Based on the results of Hegazy and Ahmed, fine particles provide better bending strength (BS) and IB properties when producing particleboard with Date Palm, however, thickness swelling is not significantly affected by fine particles [21].…”

Surface Characteristics and Acoustical Properties of Bamboo Particle Board Coated with Polyurethane Varnish

“…All the boards were air dried to a moisture content of around 9%. Two papers by Karlinasari et al [5,12] outlined the technique for obtaining fine and coarse particles, as well as the manufacturing of particle board panels. Following that, the board samples were cut into circular discs with a diameter of 10 cm and 3 cm for acoustical characteristics testing.…”
