The Effect of Press Parameters on the Physical and Mechanical Properties of Cement-Bonded Particleboards Produced from Veneer Wastes

English (OpenAlex)

This study aims to investigate the effect of press temperature and time changes on the physical and mechanical properties of cement-bonded particleboards produced using poplar veneer wastes (Populus tremula L.). In this study, single-layer cement-bonded particleboards with a target density of 1200 kg/m3 and a size of 500 x 500 x 10 mm3 were produced using 5 different pressing parameters. The physical (moisture content, density, water absorption, and thickness swelling) and mechanical (modulus of rupture, modulus of elasticity, internal bond strength, and s screw withdrawal strength) properties of the produced boards were investigated. According to the results obtained, the changes in press time and temperature did not cause a significant change in the water absorption values, while the increase in the pressing time affected the thickness swelling values positively. While the mechanical properties increased with the increase of the pressing time, values suitable for the standard were obtained in all board groups. In addition, it was determined that the most suitable time for production was 24 hours and the temperature application did not have a significant effect on the board properties
