“…Thus, the hybrid bamboo veneer waste-rubberwood particleboard did not fulfill the industry requirement for water absorption. This finding was similar to previous studies showing that particleboards produced from bamboo and mixture of bamboo and wood particles have increased WA (Calegari et al 2007;Melo et al 2009). Figure 5 shows that particle ratio does not affect the absorption of water.…”

This study investigated adhesion properties, such as buffering capacity and wettability, of bamboo and rubberwood and evaluated the physical and mechanical properties of hybrid particleboard made from bamboo (B) veneer waste and rubberwood (RW) particles. The bamboo had an acidic pH value with a high buffering capacity compared with rubberwood. Hybrid bamboo-rubberwood particleboard displayed better mechanical properties compared to 100% bamboo and rubberwood particleboard. All hybrid particleboard panels passed and fulfilled the minimum standard requirements, except for thickness swelling and water absorption tests. However, for thickness swelling test, only boards consisting of 50B:50RW and 30B:70RW passed and fulfilled the minimum TS requirements of the British Standard EN 317 (1993). Panels made from 100% bamboo veneer waste displayed the highest modulus of rupture (MOR) and modulus of elasticity (MOE) values, 15.30 N/mm 2 and 2650.14 N/mm 2 , respectively. Hybrid particleboard panels exhibited better screw withdrawal compared with panels made of only bamboo or rubberwood particles. It is concluded that bamboo veneer waste enhances the quality of particleboards, especially in terms of mechanical strength. Thus, bamboo veneer waste can decrease the dependence of the particleboard industry on rubberwood.

“…Mendes et al (2010), qualquer material lignocelulósico pode, em princípio, ser utilizado para a confecção de painéis de partículas. Melo et al (2014) fabricaram painéis com madeira (Eucalyptus grandis), bambu (Bambusa vulgaris) e/ou casca de arroz (Oryza sativa), combinados ou não. Os resultados indicaram que os aglomerados fabricados com bambu apresentaram melhor qualidade do que aqueles que utilizam casca de arroz como matéria-prima.…”

Resumo O presente trabalho objetivou produzir e avaliar painéis aglomerados empregando-se partículas de bagaço de cana-de-açúcar (Saccharum officinarum) e de pínus (Pinus taeda, Pinus elliottii), comparando-se a eficiência de dois adesivos, ureia-formaldeído e poliuretano derivado do óleo de mamona. Os painéis foram preparados com 60% de partículas de pínus e com 40% de partículas de bagaço de cana. Foram avaliadas propriedades físicas (densidade, teor de umidade e inchamento em espessura após 24 h de imersão em água) e mecânicas (módulo de elasticidade, módulo de resistência à flexão estática e tração perpendicular às faces) dos painéis de acordo com os requisitos de uso das normas NBR 14810-1 (ABNT, 2013a), NBR 14810-2 (ABNT, 2013b) e EN-312. Os painéis confeccionados com poliuretano de mamona apresentaram maior eficiência, sendo compatíveis com os requisitos físicos e mecânicos das normas brasileiras e europeia para painéis do tipo P6 (painéis estruturais para uso em condições severas de carga, em condições secas). Os painéis produzidos com ureia-formaldeído são compatíveis com painéis classificados como P2 (painéis não estruturais para uso em condições secas). Dessa forma, os resultados alcançados comprovaram a eficácia dos painéis produzidos, que podem ser empregados nas indústrias moveleira e da construção civil.

“…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.…”

Effect of Particle Size on Bamboo Particle Board 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.
