Abstract

The oxidation treatment using hydrogen peroxide and ferrous sulphate of wood particles can form free radicals of the wood chemical components essentially required in manufacturing binderless particleboard. The oxidation process is expected to have a certain optimal time. Therefore, the purpose of this study was to analyze relationship between the oxidation time and the characteristic of produced binderless particleboard. Three wood species from community forest, namely, sengon (Paraserianthes falcataria), gmelina (Gmelina arborea), and mindi (Melia azedarach) were used for treatment. The air-dried wood particles of 10~20 mesh in size were oxidized using 20% hydrogen peroxide based on particle dry-weight and 5% ferrous sulphate based on hydrogen peroxide weight. The oxidized particles were conditioned in room at different periods of time (15, 30, 45, 60, 75, and 90 min) prior to the board production. The oxidized and conditioned particles were then hot-pressed at 180°C for 15 min with a specific pressure of 25 kgf cm-2.Results showed that oxidation treatment for 15 min was sufficient to produce a binderless particleboard with good physical and mechanical properties. The characteristics of the particleboard, such as dimensional stability, modulus of rupture, modulus of elasticity, and internal bond were equivalent to that of particleboard made of particles with a longer oxidation time. The particle board made of sengon showed excellent thickness swelling (only 5.04%) and modulus of elasticity (37.184 kgf cm-2). This research result indicated that sengon was the most suitable raw material for binderless particleboard production compared to other observed wood species.

Abstract

A series of study have been conducted to analyze  the  effect  of  pretreatments  and  particle sizes on physical  and  mechanical  properties of  binderless  particleboard  (BP). The BP made  of particles from sengon wood (Paraseranthes falcataria L Nielsen) and pine wood (Pinus merkusii Jungh et. de. Vriese) which passed through 10 mesh sieve, were used  to analyze  the effect of particle pretreatments. The pretreatments were: immersion in boiling water for 30 minutes; the immersion in boiling water followed  by oxidation  using  hydrogen  peroxide and ferrous sulphate; and oxidation using hydrogen peroxide and ferrous sulphate without immersion in boiling water. The results showed that the best  phisycal  and  mechanical properties was found in board made from sengon wood particle with oxidation using hydrogen peroxide without immersion in boiling water; It had the internal bond (IB) of 6.95 kgf cm-2 and the thickness swelling (TS) of 5.74%. In the next step, the sengon wood with several particles sizes namely; passed through 20 mesh, 10 mesh, 5 mesh, 2.5 mesh, and shaving were used to produced BP. The results indicated that the MOR decreases when the particle size increases, while the IB, MOE, and TS were relatively similar for all particle sizes.
