Definitions

  • the invention relates to a method for the hydrophobic treatment of wood.
  • Wood and products made from wood are not dimensionally stable in the presence of water, moisture and heat. Water and moisture are absorbed and desorbed according to the different moisture gradients in the environment. The water absorption or water desorption is observed via the increase or decrease in weight of the wood and via the swelling or shrinking of the wood. The free water in the cells and pores of the wood is primarily responsible for the weight gain and loss. In contrast, adsorbed water on the wood fibers is the main cause of the swelling of the wood.
