By using wood shavings with citric acid and sucrose as the binder, we manufactured a particleboard and estimated the properties of the particleboard. In addition, we developed an easy method to manufacture molded products by using a clamp to compress the wood powder mixed with citric acid. A piece of this particleboard had a bending strength of 11.4-16.1MPa, higher than a particleboard made by using polyethylene as a binder. It was observed that after boiling it for 4 hours, the thickness of the sample had changed marginally. In junior high school technology classes, the students manufactured the particleboard using this method, and the method was thought to be an effective way to understand the properties of wood and wood-based materials. This newly developed method to manufacture molded products does not use a forming box and the molding is easy. Therefore, we considered this method to be significant resources as teaching materials.
