The present invention relates to furniture panels, and more particularly, to a method for preparing functional engineered wood. It includes the following steps: make veneer blanks by rotary cutting or splicing, and cut the veneer blanks into desired dimensions to obtain veneers A. Soak the veneers A in a ternary mixed solution of a biomass nanocellulose solubilizer, a fire retardant and an acid dye for toughening, fire retardation and dyeing to obtain veneers B. Add a formaldehyde decomposing powder into a modified MUF adhesive, mix them up, coat the veneers B with the mixture to obtain veneers C. Assemble and cold-press the veneers C to obtain flitches D, and saw the flitches D into desired patterns and dimensions to obtain finished products.

A system and process for producing a factory-finished engineered wood-based siding, cladding or panel (e.g., manufactured with wood veneer, strands or fibers). An overlay with a finish coating, not a primer coating, is applied to the engineered wood strand mat prior to applying heat and pressure in a press. The post-press product is cut to form panels, with an edge coating applied to color match the finish coating. The factory-finished product avoids the need to apply a final finish coating of paint on the panel face at the job site after installation, or at a separate, secondary facility post-press.

A single-pass lumber kiln includes a main drying chamber, a heat source to provide heat to the main drying chamber, a pre-heating chamber connected to a receiving side of the main drying chamber, the pre-heating chamber having a moisture collector and a kiln entrance, a supplemental heat source to provide heat to the pre-heating chamber, a conditioning chamber connected to an exit of the main drying chamber, the conditioning chamber having a moisture delivery system and a kiln exit, wherein the pre-heating chamber, the main drying chamber and the conditioning chamber are positioned such that lumber entering the kiln travels in only one direction, partitions between the main drying chamber and the conditioning chamber, and between the main drying chamber and the pre-heating chamber, the partitions having controllable dampers, fans arranged adjacent the pre-heating chamber, the conditioning chamber, and the main drying chamber, wherein some of the fans are arranged between the pre-heating and main drying chamber to transfer heat from the main drying chamber to the pre-heating chamber through the dampers, wherein the supplemental heat source provides heat to the pre-heating chamber in addition to the heat from the main drying chamber, exhaust fans arranged adjacent the kiln entrance and the kiln exit, and a fluid path connecting the moisture collector of the pre-heating chamber to the moisture delivery system of the conditioning chamber.

The invention relates to methods to thermally treat wood (e.g., flat-grain timber) to produce wood with enhanced color and/or weathering properties.

An engineering or constructional member comprising at least two strips bonded with an adhesive; each of the strips comprises bamboo impregnated or treated with a polymer derived from one or more furfuryl alcohol resin precursors.

A method for treating wood packaging materials using Radio Frequency heating includes the steps of heating wood packaging materials using RF heating and applying a pressure before the heating or incrementally applying a pressure during the heating until a temperature of the wood packaging materials reaches at least 60 C. and that temperature is maintained for at least 1 minute.

Techniques and products are described for coloring acetylated wood products. An acetylated wood product can be impregnated by a coloring medium within a chamber and the colorant or colorants contained within the coloring medium can be fixed to the acetylated wood product by the application of heat or by application of radio frequency radiation to color any external surface or interior region of the acetylated wood product which has been impregnated by the coloring medium.

Methods and articles of manufacture relating to engineered hardwood flooring are provided. Engineered hardwood flooring is produced by drying a structural layer comprising a hardwood to a moisture content from about 0.1% to about 3%, whereupon a cell structure of the hardwood collapses. The dried structural layer is humidified to where the hardwood has an increased moisture content greater than about 3%. First and second outer layers are adhered to respective first and second sides of the structural layer to form an engineered product, the structural layer sandwiched by the first outer layer and the second outer layer.
