Engineering Evaluation of Pressing Temperature Effects on Mahogany Wood Particleboard Characteristics

Abstract

Particleboard is one of the products of the use of wood powder waste that can be used by the community. This study aims to analyze the effect of 140 °C, 160 °C, and 180 °C pressing temperature variations on the physical properties and mechanical properties of particle boards made from mahogany wood powder waste. In this study, the materials used are mahogany wood powder, citric acid, and PVAC. The composition used in the manufacture of the specimen is 60% wood powder and 40% adhesive and is pressed with a pressure of 15 kg/cm2 for 10 minutes. The particleboard is tested for its physical and mechanical properties and will be compared with SNI 03-2105-2006. The results showed that the average density value ranged from 0.47-0.54 g/cm3 with the highest particleboard density value obtained at 180 °C pressing temperature. The average moisture content value ranges from 6.1-7.2% with the highest particleboard moisture content value obtained at 140 °C pressing temperature. The average MOE value ranges from 2135.7-2401.3 kg/cm2 with the highest particleboard MOE value obtained at 180 °C pressing temperature. The average MOR value ranges from 31-38.3 kg/cm2 with the highest particleboard MOR value obtained at 160 °C pressing temperature. In the physical properties test the entire particleboard has met the standard. However, in the mechanical properties test, the entire particleboard did not meet the standard. The best treatment in this study is the particleboard resulting from the treatment of a pressing temperature of 160 °C.
