Abstract

The purpose of this study was to determine optimal oxidator level in manufacture of binderless particleboard (BP) using oxidation treatment. The raw material used was candlenut wood particles (Aleurites moluccana) which pass 10 mesh in size. The air dried particles were oxidized with four levels of hydrogen peroxide, namely 5%, 10%, 15%, and 20% (based on particle dry-weight), and two levels of ferrous sulphate namely 5% and 7.5% (based on ferrous sulphate weight). The board which manufactured were 30 cm x 30 cm x 0.7 cm in size with a target density of 0.75 g cm-3. The tests were carried out based on JIS A 5908 2003. The results showed that increasing of hydrogen peroxide levels produce BP with dimensional stability and mechanical properties which getting better. Nevertheless, increasing of ferrous sulphate level did not produce any significant improvement of physical and mechanical properties of BP. The best performance of produced board is particleboard that manufacture using 20% hydrogen peroxide and 7.5% ferrous sulphate. Dimensional stability and mechanical properties of BP were fulfilled JIS A 5908 2003.
