Abstract

Particleboard is a panel product made of wood particles or other lignocellulosic materials added with adhesive then pressed. The development of particleboard manufactured using non wood biomass has become important due to the decreased of wood as main raw material for the particleboard industry. Corn husk (Zea mays L.) and Sembilang bamboo (Dendrocalamus giganteus Munro) are lignocellulosic biomass that has  potential as  renewable materials for hybrid particleboard. The purposes of this study were to determine the suitability, the effect of adhesive type, and particle composition on physical and mechanical properties of hybrid particleboard made of corn husk and Sembilang bamboo particles. The adhesive types used were urea formaldehyde (UF) and phenol formaldehyde (PF) with 10 wt% adhesive content and the composition of corn husk : Sembilang bamboo was  set at 100 : 0, 75 : 25, 50 : 50, 25 : 75, 0 : 100 (% w/w). The target density of hybrid particleboard was set at 0.80 g/cm3. The boards were manufactured at 130 °C for UF and 150 °C for PF press temperature, 10 minutes and 2.5 MPa for the pressure of the hot press. The results showed that hybrid particleboard properties improved with increasing the amount of Sembilang bamboo particles in the board. Hybrid particleboard properties affected in ascending order were modulus of rupture (MOR), modulus of elasticity (MOE), internal bond (IB) and screw holding power (SHP). Generally, hybrid particleboard bonded PF adhesive has better properties than bonded UF adhesive. Results indicated that the addition of Sembilang bamboo particles in the mixture resulted in better properties of hybrid particleboard.

Abstract

Citric acid was utilized as a bonding agent in the production of Sembilang bamboo particleboard. The limitation in using bamboo for particleboard production is that the silica content in bamboo skin can accelerate particleboard processing machines' bluntness and reduce particle adherence in particleboard manufacturing. This research aimed to investigate the influence of bamboo skin and citric acid content on the characteristics of Sembilang bamboo particleboard. Particleboards were prepared using bamboo particles (type A) and unskinned bamboo particles (type B). The citric acid solution (59%) was sprayed over the surface of bamboo particles to obtain three different levels of citric acid, i.e., 15, 20, and 25 % (based on bamboo particles’ dry weight). The Sembilang bamboo particleboards were manufactured using a hot-pressing machine at 200°C, 5 MPa for 10 min. The particleboard targeted density was 0.8 g/cm3. The type B particleboards’ internal bond (IB), modulus of rupture (MOR), water absorption (WA), and thickness swelling (TS) were superior compared to the type A particleboards. This was influenced by the lower concentration of silica in type B particleboards, which tend to allow an intimate contact area among particles and citric acid then produced better quality particleboards compared to type A particleboards. The type B particleboards met the obligation of JIS A 5908 for type 18 particleboard in terms of modulus of rupture, modulus of elasticity, and internal bond, however, only fulfilled the type 8 particleboard in terms of screw holding power.
