NOVEL USE OF WOOD SPECIMEN

摘要

The use as a casting bed of a wood object which is prepared by treating the wood object with an agent that increases the hydrophobicity of wood, and which agent is capable of reacting with the hydroxyl groups of wood. The agent that increases the hydrophobicity is particularly alkyl ketene dimer or alkenyl diketene dimer, which is brought onto the surface of the wood object in a molten state or in the form of a dispersion. When the agent reacts with the wood it also adheres to the cells of the wood, and is not flushed out into the environment.
