A method of making treated laminated veneer lumber (LVL) according to one example of the present disclosure includes obtaining assembled LVL. The assembled LVL comprises a plurality of layers of veneer wood assembled together with adhesive. The LVL is loaded into a pressure chamber. A vacuum is created in the pressure chamber thereby removing air from the plurality of layers of veneer wood of the LVL. Inorganic solution is added into the pressure chamber. The pressure chamber is pressurized to force the inorganic solution into the wood creating the treated LVL.

The present invention relates to a method of producing a wood and textile fibre protection composition from tall oil pitch. The present invention also relates to a wood and textile fibre protection composition comprising tall oil pitch and use of the composition as a wood and textile fibre protection agent.

A method for reinforcing and enhancing bamboo/wood materials employs a sulfuric acid hydrolysis method to prepare a nanocellulose dispersion solution; then with the nanocellulose dispersion solution having a certain concentration as a precursor, nano zinc oxide is in-situ produced on the surface of the nanocellulose; and the cellulose dispersion solution is improved by compounding. The obtained treatment solution is impregnated into the pores of bamboo/wood materials in a specific manner to play the role of filling, binding and consolidating the bamboo/wood tissues, so that the treated bamboo/wood materials have enhanced hardness, strength and dimension stability, and significantly-improved mildew- and corrosion-resistance. The method is suitable for the reinforcing and enhancing treatment of wood materials with relatively-loose texture, such as fast-growing wood and wood from a planted forest, and is also suitable for the reinforcement and restoration of slightly-rotten wood materials.

Wood markers and processes for durably marking and subsequently identifying both original grain wood products and wood-plastic composite products. The wood marker can be dispersed beneath the surface of the wood, where it is protected from the elements and may endure years of exposure to the elements. The wood marker is compatible with state-of-the-art pressure-treating processes and may subsequently be detected for authentication purposes by known analytical methods.

Systems and methods for treating wood products are provided. The methods comprise preconditioning the wood product by irradiating one or more surfaces of the wood product with infrared (IR) and/or ultraviolet (UV) radiation and subsequently treating the wood product. The systems comprise one or more fixtures positioned to irradiate one or more surfaces of the wood product with IR and/or UV radiation, wherein each fixture comprises a reflector and a radiation source.

A fire-resistant wooden pressure plate is formed by conducting a cold pressing of 2-10 MPa to the uniformly mixed not less than 50 wt % of a wood-containing powder material and an additive. The additive may include metallic oxide, non-metallic oxide, hydrochloride, sulfate, phosphate, weak acid, and strong acid. With class-A fire resistance, in-water rotting resistance, class-0 mold resistance, little or no detectable formaldehyde, some products described herein can replace traditional plates incapable of resisting fire in the following fields: 1. wooden veneer, wooden door, furniture, kitchenware, etc.; 2. wooden wall, base course, ground foundation, suspended ceiling, etc.; 3. wooden flooring; 4. wooden fire-resistant door, fire-resistant wall, etc.; 5. wooden house, wooden bench, wooden bulletin plate, wooden billboard, walkway paving, etc.; 6. wood handicrafts, toys, etc.
