Abstract
Agricultural straws such as rice and barley were used as partial replacement of raw materials for particleboard (PB) manufacture. A melamine-urea-formaldehyde (MUF) resin, based on 5 percent melamine addition of the resin solids weight, was synthesized in the laboratory for the bonding of PB. PBs were made using two straw particles based on 10, 20, 30, 40% oven dry weight addition with MUF resin. PBs were tested for physical and mechanical properties, and water soak dimensional stability. The results indicated that as rice and barley straws addition level were increased, the properties of IB, MOR and dimensional stabilities such as thickness swell and water absorption were decreased. Overall, the agricultural straws can be used at 15% substitution of raw materials for PB manufacture.
