Abstract
ABSTRACT The objective of this study is to assess the effect of the laminar inclusion on the physical and mechanical properties of sugarcane bagasse particleboard. We used the commercial panels of sugarcane bagasse produced in China. To evaluate the effect of the laminar inclusion was tested two wood species (Pinus and Eucalyptus) and two pressures (10 and 15 kgf.cm-2) along with a control (without laminar inclusion). The panels with laminar inclusion obtained improvements in the physical properties, with a significant reduction in the WA2h, WA24h and TS2h. There was a significant increase in the properties MOE and MOR parallel and Janka hardness, while the properties MOE and MOR perpendicular decreased significantly. The pinus and eucalyptus veneers inclusion resulted in similar results when added to the panel with a 10 kgf.cm-2 pressure. The use of 15 kgf.cm-2 pressure is not indicated for the pinus veneer inclusion in sugar cane bagasse panels. There was no effect of the pressure level when evaluating the eucalyptus veneer inclusion on the properties of the sugarcane bagasse panels.
Highlights
The furniture sector in Brazil has shown tremendous growth and development over the recent years, leading to a significant increase in the production of particleboard, given their wide use in furniture manufacture (OLIVEIRA, 2016).In panel manufacture, currently wood from planted forests is primarily used, those of the genus Pinus and Eucalyptus
Which results in approximately 46 million tons of sugarcane bagasse, because according to Silva et al (2007), each ton of processed sugarcane produces a total of 280 kg of waste
The commercial sugarcane bagasse particleboard produced in China were used
Summary
Currently wood from planted forests is primarily used, those of the genus Pinus and Eucalyptus In principle, these panels can be produced by utilizing any lignocellulosic material, which can confer high mechanical strength and exhibit good physical characteristics (ROWELL et al, 2000; MENDES et al, 2012). In light of this knowledge, the utilization of the waste generated by the agribusiness is considered a good alternative to meet the demand of the panel industry. Which results in approximately 46 million tons of sugarcane bagasse, because according to Silva et al (2007), each ton of processed sugarcane produces a total of 280 kg of waste
