This application relates to the technical field of building material processing, and more particularly, to a method for manufacturing a transparent heat-insulation building material based on waste wood. The method includes the following steps of: step S1, wood pretreatment, step S2, wood acetylation treatment, step S3, resin impregnating, and step S4, hot press molding to obtain a densified wood.

Near InfraRed NIR technology, including NIR cameras and detectors, is used to accurately identify surface irregularities on a veneer surface. A grade is then assigned to the veneer based, at least in part, on the detected irregularities. In one embodiment, the veneer is then provided to an improved veneer stacking system that produces more consistently graded veneer stacks and safer veneer stacks, is less expensive to operate, and is far safer than currently available methods and systems for full veneer sheet, veneer strip, and partial veneer sheet stacking.

Disclosed herein are compositions and methods for treating wood to give it a desirable color that is durable over time, while at the same time rendering the wood resistant to fungal decay and insect attack. The wood may be pressure treated in a two-step process whereby the wood is first treated with a wood preservation composition, and then treated with a composition comprising pigments, or vice versa. Alternatively, the wood may be simultaneously treated with a composition comprising a wood preservative and a composition comprising pigments.

Near InfraRed NIR technology, including NIR cameras and detectors, is used to accurately identify surface irregularities on a surface of a veneer sheet or other wood product. Based on the identified surface irregularities for a given wood product, one or more actions are taken with respect to wood product or production process to ensure the wood product is put to the most efficient, effective, and valuable use.

A system that applies liquid conditioning agent to at least one of a plurality of sides of an untreated board is provided. One embodiment has an enclosure with a first side having a first aperture and an opposing second side with a second aperture having dimensions that correspond to the width and thickness of the untreated board; a spray applicator system comprising a plurality of spray nozzles located within a chamber and oriented inward, wherein the liquid conditioning agent is sprayed through the spray nozzles onto at least one of the sides of the untreated board as the untreated board passes through the chamber of the enclosure; a plurality of brushes located after the spray applicator system, wherein the liquid conditioning agent is brushed onto the sides of the untreated board, wherein the untreated board enters through the first aperture, and wherein a treated board exits through the second aperture.

The present description relates to processes, water-based wood treatment solutions and kits for treating wood substrates so as to obtain colored (or altered) wood substrates, where mineral compounds that impart the color or other desirable characteristic(s) to the wood substrates are formed in the colored or altered wood substrates. The mineral compounds formed comprise the products of a chemical reaction which occurs between the wood substrate, a metal salt, and an oxygen source.

A process and formula for producing a simulated weathered wood finish calls for a mixture including water, acrylic, (2-butoxy-1-methylethoxy)propan-2-ol and (2-methoxymethylethoxy)propanol. A quantity of sodium bicarbonate is added to the mixture in a ratio of between 1 part to 5 parts of the sodium bicarbonate to 100 parts of the mixture. This creates a solution which is applied to the surface of wood to create an aging effect on the wood.
