Properties of Blue-Stain Masson Pine after Compression and Thermal Modification

Abstract:

In this paper, in order to eliminate the adverse effects of blue-stain on the wood surface appearance and improve wood mechanical properties, wood compression process and wood thermal treatment process were applied into the physical modification of blue-stain Masson Pine (Pinus massoniana). The test results showed that when the specimens are hot-pressed with the compression rate of 50%, and then were heat-treated at 220°C for 2h, the wood surface color and dimension stability could be improved significantly. Moreover, the surface hardness and the compression strength of the compressed-thermal treated wood could be increased significantly compared to the untreated blue-stain wood. Based on this study, the biological properties of the specimens after compression and thermal treatments will be investigated in the future.
