| Abstract: |
| In order to investigate the effect of different wood species on the curing of MUF resin, DSC spectroscopic analysis and a new procedure are used, an important component in wood composites manufacturing. The MUF resin is synthesised with an initial weak acidic condition. The final molar ratios of F/(M+U) and M/U are 1.37 and 0.32, respectively. Samples are prepared by mixing MUF resin with wood flours from different wood species. The curing behaviour and transformation of chemical groups are analysed by DSC. The curing activation energy of MUF resin generally decreases when the resin is mixed with wood flours due to the influence of wood extracts. When the heat rate is 5 ℃/min, the relationship between the peak temperature of the MUF resin and pH values or base buffer capacities is observed. |
