  • Publication number: 20080075874
    Abstract: A chemical composition that has been specifically created for use in treating wood and wood products. The composition preferably comprises non-toxic and environmentally safe components which react with molecules of the wood. When the composition comes in contact with the wood, a reaction occurs which causes a molecular change in the wood itself. This molecular change improves the wood's strength and durability while simultaneously rendering the wood impervious to water, fire, rot, fungus, insects and many other potentially damaging environmental conditions.

  • Patent number: 6902767
    Abstract: Wood cellulose is treated with a reactive silicate. The reaction is done to cellulose within the wood and may be catalyzed with acid or base catalysts or a carbon silicon halogen combination which produces in situ acid catalysts or a different combination to produce an in situ base catalyst which replaces some of the molecules or atoms within the cellulose structure with silicon, boron or other hydrophobic or anti-degrading agents. Preferably an organic solvent, such as alcohol is used to accelerate the reaction with the water in the wood. Here, the hydroxyl (OH) group on some or all of the cellulose molecules is partially replaced with silicon or an alternative atom or molecule to changes the character of the wood. The process may be modified to insert a preliminary step of adding a reactive agent to be locked into the wood. Manufacturing techniques to enhance the process using ultrasound or other wave generating techniques are also taught.

  • Publication number: 20030059545
    Abstract: The treatment of the wood with a reactive silicate which is preferably a carbon silicon halogen combination which replaces some of the molecules or atoms within the cellulose structure with silicon. Here, the hydroxyl (OH) group on some or all of one or more of the cellulose molecules is partially replaced with silicon or an alternative atom or molecule to changes the character of the wood. The process may be modified to insert a preliminary step of adding a reactive agent to be locked into the wood.

  • Patent number: 4581243
    Abstract: A self-contained, portable wood treating apparatus and method for treating wood is disclosed. The wood treating apparatus includes a generally flat base in which a water tank is contained. A cylindrical pressure vessel is located above the base. A pair of elongate work tanks are located on respective sides of the pressure vessel between the pressure vessel and base. A reagent tank is also provided adjacent the base in which a concentrated treatment liquid is contained. A treatment system is provided for treating the wood located in the pressure vessel with a dilute treatment liquid contained in the work tanks. The treatment system includes a make up system for making up additional dilute treatment liquid by mixing water from the water tank and concentrated treatment liquid from the reagent tank. The improved method of operation includes the forming of dilute treatment liquid which is pumped into the pressure vessel to pressurize the pressure vessel and wood therein.
