A process for producing a smooth-sided strand-based siding or wood structural panel using a pre-telegraphing process. The pre-telegraphing is performed after the primary process completes pressing and consolidation of the substrate/board. The pre-telegraphing process applies a water spray on the hot board immediately out of the primary process press, and before overlay application. The application of the water spray causes the surface of the board to swell and cure. A settling period follows to allow the top surface particles and strands to swell along with absorption and evaporation of the moisture. This is followed by surface sanding to remove the telegraphing and produce a smooth surface. This may then be followed by lamination of overlay(s). The process is completed by post-lamination treatment and coating of the board.

Methods of manufacturing a fire-retardant treated OSB to avoid press build-up issues with prior art fire retardants such as boric acid when subjected to normal heat and pressure used in forming an OSB panel. In one embodiment, the press temperature is reduced to below the melting point or softening temperature of the boric acid and/or prior art fire retardants, with a fast-cure adhesive system used in the mat to provide sufficient bonding and integrity while using a lower press temperature. Alternatively, a zinc borate or calcium borate dispersion, with melting points higher than normal press temperatures, is applied to the wood strands prior to pressing. The zinc borate and/or calcium borate are not melted or softened during the OSB manufacturing process, thereby avoiding the press build-up issues with boric acid.

A filler material is applied to a plurality of wood elements. The plurality of wood elements is bonded into a composite wood product, where the bonding includes delivering ultrasound energy to the plurality of wood elements. The ultrasound energy has a frequency within a frequency range of 10 kHz-20 MHz.

Disclosed is a board made from acetylated mbberwood elements and a method for making same. The acetylated rubberwood elements have an acetyl content of at least 17% and/or are prepared by acetylating mbberwood elements using an acetylation agent in the vapour phase. The invention also pertains to acetylated rubberwood elements prepared by using an acetylation agent in the vapour phase.

It is provided a process to modify lignocellulosic materials with lignin, and incorporating lignin and isocyanates or other wood adhesive in wood products compositions, and their composition, preparation and application for bonding wood products are disclosed. The compositions comprise lignin, derived from a variety of natural resources, isocyanate compounds containing two or more isocyanate functional groups, or other wood adhesives.

A method for manufacturing a three-dimensionally deformed plate made of a wood fiber material comprises providing a prefabricated, flat wood fiber material plate as the original plate, preheating the original plate in sections, wetting the preheated section of the original plate with an atomized liquid mixture of water and a separating agent, introducing a section of the original plate that is preheated and wetted with a liquid mixture of water and a separating agent between two rollers of a molding station, wherein the rollers respectively provide a corrugated profile in the peripheral direction of the external surface, such that the original plate is being deformed in sections into a plate with a wave shape, wherein rollers are being used, the respective profiling of which has half-waves which follow one another in the peripheral direction and which at least partially have a different extension in the peripheral direction.
