Apparatus for viscoelastic thermal compression of wood

摘要: Viscoelastic Thermal Compression (VTC) of wood is a treatment which greatly improves material properties by means densification with mechanical compression perpendicular to the grain. VTC similar other processes, but designed for thin lamina and employs dynamic temperature steam pressure conditions. A device was constructed that capable producing wood. Details construction operation are presented. The consists pressurized chamber variable volume. Wood density may be modified from initial virgin up approximately 1400 kg/m3. Control insures cell walls not fractured during process. batch adapted conventional laboratory hot-press. An example operating schedule described, procedures possible within design parameters device.
