A wood treatment apparatus for long-term treatment of wood has a cylindrical hollow body and a sleeve. The cylindrical hollow body has an inner end, during use located within the wood, an outer end, directed away from the inner end, an exit opening and an accommodating space accommodating a carrier material containing active wood-treatment substance. The sleeve is arranged around the cylindrical hollow body and, when the apparatus is not in use, closes the exit opening and, when the apparatus is used, frees the exit opening and brings the accommodating space into contact with the wood. The method provides driving the apparatus into the wood to position the exit opening near a site to be treated and displacing the sleeve to bring the accommodating space into contact with the wood, wherein the apparatus remains in the wood to allow the wood-treatment substance to be released pressureless into the wood.

A cross-laminated panel including a first layer, a second layer, and a third layer. The first layer of the cross-laminated panel having first boards oriented in a first direction. The second layer of the cross-laminated panel having second boards oriented in a second direction, the second direction being substantially perpendicular to the first direction. The third layer of the cross-laminated panel having third boards oriented in the first direction. The cross-laminated panel also including adhesive situated between each of the first layer, the second layer, and the third layer. The cross-laminated panel further including a hollow member forming a conduit and disposed in any one of the first layer, the second layer, and the third layer.

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.

The present invention provides a solution and related composition of matter and methods which synergistically improves a fungicide's effectiveness in resisting undesired fungal growth. The invention also provides wood and wood products which have been treated with the solution, method or compound.

A multifunctional broad spectrum antimicrobial composition is described. The composition can be incorporated into a wood preservative, or used as an additive to provide antimicrobial properties to water-based wood coatings. The composition is a concentrated water-miscible emulsion containing 3-iodo-2-propynyl N-butylcarbamate (IPBC), carbendazim (BCM) and propiconazole (PPCZ), and has antimicrobial activity against a wide variety of fungal organisms, including surface molds, blue stain fungi and wood rotting fungi. The composition can act as an in-can preservative and is useful for antimicrobial protection of wood and wood-based substrates.

Methods for treating cellulosic materials comprising introducing a liquid treating composition into the cellulosic material, the treating composition comprising a solution prepared from at least: (i) one or more of a copper amine complex or copper amine complex, such as copper tetraamine carbonate, (ii) one or more of ammonia or a water-soluble amine and (iii) water; and exposing the cellulosic material provided thereby to carbon dioxide and/or carbonic acid to provide treated cellulosic material, and treated cellulosic materials prepared thereby.

Here are described boroxine-containing compounds and their compositions for the treatment of wood. For instance, the treatment of wood includes its protection against moisture and/or degradation caused by insects or microbes.

A synergistic aqueous wood preservative composition comprising a copper compound and penflufen. The copper compounds of the compositions of the invention may be soluble, partially solubilized or micronized particles. The penflufen of the compositions of the invention may be solubilized, emulsified or particulate. The wood preservative compositions of the present invention are surprisingly provided as stable dispersions and confer surprising and unexpected resistance to treated wood and wood products.
