Abstract

In this study, the effect of wood particle surface oxidation on the reduction of the amount of resin consumption for single layer particleboard production was investigated. Oxidation of WOOD PARTICLES forms carboxylic groups and free phenolic radicals that lead to activated surface on WOOD PARTICLES which helps bond development. In this search Populus nigra WOOD PARTICLES were oxidized by 0, 2, 4 and 6 percent (based on OD weight of wood) of 40% nitric acid. These WOOD PARTICLES were then blended with one of the three amounts of 3, 5 and 7% (based on OD weight of wood) PHENOL FORMALDEHYDE resin. Then, the wood particle mats were formed and pressed using the pressing conditions of 180 oC, 5 minutes pressing time and 30 kg/cm2 pressure. The results indicated that maximum MOR, MOE and minimum water absorption and swelling thickness was observed in boards produced using 7% resin and 4% acid. Using 5% resin and 4% acid showed the best performance on shearing strength.
