Abstract
Systems and methods of making a wood enhancement agent treated engineered wood product. The wood enhancement agent typically includes at least one of a preservative, a water repel but, a fungicide, an insecticide, a stabilizing agent, wax, an ultra-violet light inhibitor, and combinations thereof, and may also include an antioxidant. The wood enhancement agent is incorporated into the engineered wood product during a billet making process or after forming the billet. The wood enhancement agent may be applied to a warm billet after steam press, or to a reheated billet, by dipping, spraying, or flood coating the billet, or by diffusion, vacuum impregnation, pressure, or a combination thereof.
Claims24
A method of making a wood enhancement agent treated engineered wood product comprising the steps of:
- a. providing a steamed-pressed warm billet;
- b. applying an effective amount of a wood enhancement agent to the steamed-pressed warm billet to substantially cover the surface thereof with the wood enhancement agent;
- and
- c. allowing the wood enhancement agent treated warm billet to cool down, thereby obtaining a wood enhancement agent treated billet.
A method of making a wood enhancement agent treated engineered wood product comprising the steps of:
- a. providing a pressed billet of scrim-based wood material at first temperature;
- b. heating the billet of material to a second elevated temperature above that of the first temperature;
- c. applying an effective amount of a wood enhancement agent to the billet to substantially cover the surface thereof with the wood enhancement agent;
- and
- d. allowing the wood enhancement agent treated billet to cool, thereby obtaining a wood enhancement agent treated billet.
