A method for producing wood material boards with reduced emission of volatile organic compounds (VOCs), including: a) producing woodchips from suitable timbers; b) heat-treating at least one portion of the woodchips at a temperature between 150 C. and 300 C. for a period of 1 to 5 hours; c) crushing the wood chips that are not heat-treated and at least one portion of the heat-treated woodchips by machining in order to obtain wood shavings or by solubilizing in order to obtain wood fibers; d) gluing the wood shavings or wood fibers with at least one binding agent; e) applying the glued wood shavings onto a transport belt while forming a multi-layered shavings cake or applying the glued wood fibers onto a transport belt while forming a single-layer fiber cake; and f) compressing the shavings cake or the fiber cake to form a wood material board.

Techniques and products are described for coloring acetylated wood products. An acetylated wood product can be impregnated by a coloring medium within a chamber and the colorant or colorants contained within the coloring medium can be fixed to the acetylated wood product by the application of heat or by application of radio frequency radiation to color any external surface or interior region of the acetylated wood product which has been impregnated by the coloring medium.

The disclosure relates to a method for the production of wood fiberboards such as MDF boards.

Disclosed is a method of manufacturing bamboo toothbrush and a toothbrush manufactured thereby. According to the method of manufacturing bamboo toothbrush of a detailed embodiment of the present invention and a toothbrush manufactured by the method, it is possible to improve strength, surface roughness, and moisture resistance of a bamboo and adjust the color of the bamboo using hot pressing. Further, since sanding and polishing and separate coating and drying are not performed, the process time is reduced, whereby the manufacturing cost can be reduced.

Disclosed are a bamboo outer skin-retaining bamboo veneer and a preparation process thereof, belonging to the technical field of bamboo processing. The preparation process includes the following steps: segmenting bamboo and cutting into bamboo strips with an arc-shaped section; softening the bamboo strips by pressurizing and heating, and unfolding the softened bamboo strips at equal arc and fixed thickness; performing double-sided protection and gradual flattening under a condition of heat preservation until the bamboo strip is completely flattened, to obtain a bamboo board; and continuously cooling the bamboo board, shaping the bamboo board under a heavy weight and then drying, and then trimming under a fixed width to obtain the bamboo outer skin-retaining bamboo board finished product. The bamboo outer skin-retaining bamboo strip can be unfolded under the promise of not destroying the bamboo outer skin surface, and there will be no cracking and rebound problems.

A process for treating wood strands suitable for producing OSBs includes treating the wood strands in water at a temperature in the range from 50 C. to 100 C. The present invention likewise relates to a process for producing wood-based OSBs, in particular wood-based OSBs having reduced emission of volatile organic compounds (VOCs), including: a) production of wood strands from suitable timbers; b) treatment of at least part of the wood strands with water; c) drying of the wood strands which have been treated with the water; d) coating of the wood strands which have been treated with water and dried and coating of wood strands which have not been treated with water with at least one binder; e) scattering of the glue-coated wood strands on a conveyor belt; and f) pressing of the glue-coated wood strands to give a wood-based OSB.

The present invention relates to a process for preparing a modified wood product wherein a step of resin treatment is followed by a thermal modification step. The present invention also relates to a modified wood product produced using said process.

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.

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