The invention relates to a process for forming a wood-base product comprising the steps of a) providing particles of wood, b) resinating the particles of wood with a binder, c) compressing the resinated particles of wood to form a wood-base product, wherein before, during or after step b) the particles of wood and/or the binder are brought into contact with a broken dispersion. The invention also relates to the use of a polyfunctional compound as demulsifier for breaking a wax-containing dispersion. The invention further relates to a broken dispersion for hydrophobicizing lignocellulose-containing material. The invention additionally relates to a two-component system containing at least two components A and B: a wax-containing dispersion A) and a demulsifier B) having at least one functional group for breaking the wax-containing dispersion.

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

A wooden drum shell that is treated by direct heating by exposure to a flame to alter the state of fibers in an outer layer of the drum shell relative to the untreated drum shell or inner fibers below the outermost layer. A method of manufacturing a treated drum shell includes selecting a wooden starting material, forming an untreated drum shell from the starting material, and exposing the drum untreated drum shell directly to a flame.

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.

Near InfraRed NIR technology, including NIR cameras and detectors, and machine learning methods and systems, including one or more Machine Learning (ML) based surface irregularity prediction models, are used to accurately identify surface irregularities on a surface of a wood product, such as a veneer sheet or ribbon, and provide irregularity prediction data for the wood product. Based on the irregularity prediction data for a given wood product, one or more actions are taken with respect to wood product or the production process to ensure the wood product is put to the most efficient, effective, and valuable use.

Near InfraRed NIR technology, including NIR cameras and detectors, are used to detect irregularity in the surface of a wood product. Based on the detected irregularities at various locations in a given wood product, one or more actions are taken with respect to a production process used to produce the wood product to ensure the wood product is put to the most efficient, effective, and valuable use.

Disclosed is a process for the acetylation of wood, wherein the wood is impregnated with acetylation fluid and heated in stages. It is thereby secured that an acetylation reaction is conducted at a temperature above the boiling temperature of the acetylation fluid, at a stage where the impregnated wood is largely devoid of free acetylation fluid (i.e., acetylation fluid not retained in the wood matrix or in capillaries). Preferably, the process is conducted in a plant having conveyors, such as transportation screws, in the zones in which the separate heating steps are conducted.

A shipboard apparatus (300) for heat treating wood chips, for service in the trade and for export to receivers within the forest products industries and the biomass energy sectors. The purpose of heat treating wood fiber is to provide certification to meet the phytosanitary requirements of wood fiber importing countries, infusion of moisture laden, saturated heated air using a closed loop system (301, 303a, 303b, 304a, 304b, 305, 310) within the holds of the ship with the heating apparatus being situated on the quay while the ship is being loaded with wood chips. The completed heat treating process renders the cargo acceptable for issuance of a phytosanitary certificate.

This invention concerns a heat treatment device intended to be associated with an intermodal container (3) loaded with logs, comprising a pressurized water steam supply line (1). Said heat treatment device is particular in that it comprises at least one, preferably two, substantially rectilinear tube (2), provided with a plurality of openings distributed over its length and circumference, said at least one tube (2) being intended to be introduced from the rear into said intermodal container (3) loaded with logs, and to be supplied by said pressurized water steam.

This invention also concerns a method that can be implemented by means of a device depending on the invention.

A treatment process and wood products thereof including a product formulation of a single phase solution combining a wood preservative (durable component) with a Flame Retardant component (FR) to produce a durable Flame Retardant (dFR) treated wood product. The durable component comprises a range of copper based and non-copper based wood preservatives, while the FR component comprises alkali metal silicates and alkali metal aluminate compounds. The dFR working solution undergoes chemical impregnation (treatment) followed by a heat (fixation) process step that locks the chemical into the wood making it non-leachable. The dFR treated wood products are tested for their enhanced fire performance properties. When heated, wood undergoes thermal degradation and combustion producing gases, vapors, tars and chars. Using a cone calorimeter burn test method, dFR treated wood products show a significant reduction in heat release rate, mass loss rate and smoke generated values compared to untreated radiate pine.
