“…Several studies on the experimental manufacture and particleboard quality using different bamboo species and wood particles, isolated or mixed, have been carried out; for example, those conducted by Vital & Haselein (1988), Calegari et al (2007), Arruda et al (2011), Morais (2011), Melo et al (2014, Valarelli et al (2014), Morais et al (2015), Nurhazwani et al (2016). Among these studies, only that carried out by Nurhazwani et al (2016) used Dendrocalumus asper bamboo, and none of them addressed the influence of particle size on panel properties.…”

In this work, bamboo chips (Dendrocalamus asper) were crushed according to four particle size classes (A = -35+40 mesh; B = -40+48 mesh; C = -48+60 mesh; D = -60+65 mesh) to produce particleboards with four different compositions (100%A; 75%A + 25% B; 50%A + 50%B; 25%A + 25%B + 25%C + 25%D). Each composition was considered a treatment. The aim was to verify the effect on the physical and mechanical properties of panels. The test methods and requirements to evaluate the properties were based on NBR 14810 Brazilian standard. The results showed that the particle size used in compositions showen no significant effect on moisture content, density, thickness swelling (24 hours), internal bonding or resistance to screw withdrawal (face and side) of panels. Significant effects were verified on water absorption (2 and 24 hours), thickness swelling (2 hours), MOR and MOE to static bending.

“…Nascimento et al reported that the values of WA for medium density of the particle boards which employed from Eucalyptus and Pinus had an average value between 12% and 16% for water absorption in 2 hours [19]. Valarelli et al [20] also reported the similar results for the particleboards from bamboo and castor oil based adhesive.The effect of particle size of material on the water absorption is not significant. However, from both results (WA and TS), it shows the ability of particleboards to produce the lower percentage of WA was increased as the ratio of resin was reduced.…”

The formaldehyde-based adhesives have always been chosen for manufacturer in the making of particleboard because of the cost. However, it has low moisture resistance and high water absorption. At the same time, formaldehyde-based adhesive also produced gaseous emission that can cause cancer and bronchial health. Meanwhile, the high water resistance, low moisture content and healthy to the human body nowadays becomes most important issues in the making of furniture for market. This research was discusses on the ability of Acacia tree as raw material and polyurethane (PU) as an adhesive for making the homogeneous particleboard. The aim of this research is to looking the impact of using different particle sizes from Acacia tree to the physical properties of the end product. This study also focuses on the potential of paraffin wax as a water repellent agent. The testing of physical properties was includes the thickness swelling (TS) testing, moisture content (MC), density and water absorption (WA testing). The size of Acacia particle was varied from x<2mm, 4mm>x>2mm and x>4mm. All particleboards produced was achieve the range of medium density according to the Japan Industry Standard (JIS). The results have shown that the value of the density and the particle size was influenced the result especially for the physical properties. From this research it is proved that the PU as a resin and sawdust of acacia tree with some specific size can be a good binder and material for the particle board industries in future. The paraffin wax also showed a great potential as a water repellent agent based on the reduction of water absorption of the particleboard. The particleboard with sizes between 2mm to 4mm proves better results compared to the smaller or bigger sizes of particle.

“…Although there are no competitive engineered bamboo industries in Brazil, a high local potential, regarding the bamboo plantation and commercialization, makes reasonable to perform scientific research related to the development of high value-added products using bamboo. In fact, several studies have been made in Brazil using agricultural waste for the particleboard production (Calegari et al 2007, Fiorelli et al 2012a, Fiorelli et al 2012b, Fiorelli et al 2014, Belini et al 2014, Valarelli et al 2014, Zaia et al 2015. Qisheng et al (2001) classified bamboo panels according to their material composition and product structure: bamboo-plywood products, laminated products (laminated bamboo from strips), chipboard products (bamboo chip/particleboard) and composite board products.…”

“…The resin normally consists of an organic adhesive: urea formaldehyde, phenol formaldehyde, castor oil-based polyurethane resin, polyvinyl acetate (PVA) and others. The following processes are normally performed for the production of bamboo particleboards: the obtained bamboo chips/particles are dried, mixed with resin, pre-formed and hot-pressed in the form of panels (Valarelli et al 2014).…”

Due to the high dimensional variation of bamboo, the manufacturing of materials such as plywood and laminated bamboo produces a high amount of residues. The production of particleboards could be used to overcome this problem and become a viable solution to reuse the generated waste as a raw material to high value-added products. This study aimed to present an overview of the bamboo particleboard production, as well as the mechanical and physical properties of this material, followed by a review of the advances in its research and development. In general, independently of the resin or bamboo species utilization, several bamboo particleboards meet the mechanical properties requirements of international standards for wood-based medium-density particleboards. The main focus of this study is to provide a review, in order to support research groups interested in using new bamboo-based materials for the development of manufactured durable products.
