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.

An amorphous polylactic acid polymer having a weight average molecular weight in the range of about 35,000 to 180,000 is described. The polylactic acid polymer composition can be hammer milled without cryogenics result in the form of particles wherein 90% of the particles have particle size of about 250 m or less and the material has a glass transition temperature of between about 55 C. to about 58 C. and a relative viscosity of about 1.45 to about 1.95 centipoise.

A system and method for a fire-retardant insulation product are provided, along with a fire-retardant chemical formulation. An insulation product provided includes cellulose fibers and a fire-retardant chemical formulation. The fire-retardant includes calcium chloride.

The invention relates to a porous carrier system for reducing the emission of formaldehyde in a wood-based material, which comprises a formaldehyde-binding substance A and a hydroxide-releasing substance B. The invention further relates to a method for producing the porous carrier system, the use of the porous carrier system to reduce the emission of formaldehyde in a wood-based material, a wood-based material comprising the porous carrier system, and a method for producing said wood-based material.

A web structural body includes cellulose fibers and a binding material binding the cellulose fibers, and in the web structural body described above, a molten rate of the binding material at a surface of the web structural body is higher than a molten rate of the binding material at a center in a thickness direction of the web structural body.

The present invention relates to a particle board, a process for manufacturing the particle board as well as the use of at least one particulate calcium carbonate-containing material as wood particle replacement in a particle board.

A method for producing thermosetting phenolic resins includes the step of reacting a polycondensable phenolic compound with 5-hydroxymethylfurfural (HMF) under conditions leading to the formation of polycondensation products. The HMF includes at least one HMF oligomer, and the reaction step is carried out at pH values greater than 7 for more than 60 minutes. Further, thermosetting phenolic resins may be used for producing a wood composite material.

The present invention provides a bamboo strip substrate board and a preparation method thereof, a bamboo strip floor and application thereof. The method for preparing a bamboo strip substrate board provided by the present invention includes the following steps: placing a bamboo strip curtain in a glue-containing solution for glue dipping and draining glue to obtain a glue-containing bamboo strip curtain; drying the glue-containing bamboo strip curtain and then performing assembly to obtain a bamboo strip board blank; and subjecting the bamboo strip board blank to hot pressing to obtain a bamboo strip substrate board. According to the present invention, an outdoor bamboo-based floor is further prepared on the basis of a bamboo strip substrate board. The present invention a simplified preparation process, so the production cost is effectively reduced, and the weather resistance of the floor is improved.

Methods of forming a lightweight reinforced thermoplastic core layer and articles including the core layer are described. In some examples, the methods use a combination of thermoplastic material, reinforcing fibers and bicomponent fibers to enhance retention of lofting agents in the core layer. The processes permit the use of less material while still providing sufficient lofting capacity in the final formed core layer.
