Abstract
Method of delivering compositions to organic substrates, particularly lumber. Method involves heating a target zone of the substrate and then applying the composition to the surface of the substrate wherein the temperature of the composition is lower than that of the target zone of the substrate. Compositions include biocidal, strength modifiers, waterproofing and polymers.
Claims31
A method of delivering an aqueous composition to a kiln dried lignocellulosic substrate, the method comprising at least the steps of:
- a. heating a target zone of the substrate using radio frequency energy or microwave energy, and
- b. applying the composition to a surface of the substrate comprising or immediately adjacent to the heated target zone;
- wherein the composition is at a temperature below that of the heated target zone at the time the composition is applied, the difference between the temperatures of the composition and the heated target zone being sufficient to reduce pressure in the substrate after the composition is applied, allowing for an uptake of less than 100 l/m3 of the composition into the substrate
A method of delivering an aqueous composition to a lignocellulosic substrate the method comprising at least the steps of:
- a. heating a target zone of the substrate using radio frequency energy or microwave energy, and
- b. applying the composition to a surface of the substrate comprising or immediately adjacent to the heated target zone;
- wherein the lignocellulosic substrate has a moisture content of less than 15% as a weight proportion of dry weight prior to the heating step and the composition is at a temperature below that of the heated target zone at the time the composition is applied, the difference between the temperatures of the composition and the heated target zone being sufficient to reduce pressure in the substrate after the composition is applied, allowing for an uptake of less than 100 l/m3 of the composition into the substrate.
