An adhesive for heat press molding contains a reaction product obtained by heat treatment on a mixture containing a polycarboxylic acid and a saccharide.

A method for manufacturing a fiber formed body includes forming a fiber board into a predetermined outer shape while forming a pattern on an outer surface of the fiber board by compressing the fiber board, a forming at least one positioning member by compressing the fiber board, and positioning, relative to a cutoff device, the fiber board using the positioning member, and cutting off a cutoff target part of the fiber board using the cutoff device. In the method for manufacturing the fiber formed body, formation of the pattern during the forming of the outer shape and formation of the positioning member during the forming of the positioning member are simultaneously performed.

A method for producing an ultra-stable and enhanced solid wood flooring for under-floor heating via surface compression technique includes: subjecting, while subjecting a solid wood to surface compression and enhancement, the solid wood to primary stabilization treatment by controlling a temperature of a hot pressing plate to obtain a compressed enhanced solid wood; putting the compressed enhanced solid wood into a heat treatment tank; and subjecting the compressed enhanced solid wood to secondary stabilization treatment by controlling a pressure and a temperature of steam or air in the heat treatment tank and a treatment time to obtain a finished product. The ultra-stable surface-compressed enhanced solid wood flooring produced by the method features high dimensional stability, low set-recovery after water absorption, and desired moisture and heat resistance.

An engineered wood based siding, cladding or panel with a microstrand interface layer (MIL) applied to the top of the main strand matrix layers to minimize telegraphing, add rigidity and strength, and provide an improved surface appearance. The MIL comprises microstrands applied to the surface of the strand matrix or mat during production, prior to deposition of a fines layer. The MIL prevents the loss of fines into the strand matrix, and helps prevent or eliminate strand telegraphing.

Coconut husk and coconut shells are primarily considered agricultural waste. Therefore, coconut shells are often burned, which is terrible for the environment and contributes significantly to CO2 and methane emissions. Thus, the present invention provides an eco-friendly use for coconut waste by turning coconut fibers into thermo-acoustic insulation. The present invention also describes methods of producing said insulating compositions.

A membrane covered panel and a membrane covered panel production method are provided wherein an elastomeric membrane, and preferably, an aqueous elastomeric resin-based membrane, is applied to a finished panel construct, prior to pressing of the membrane covered panel. The method is used to produce panels which can be used in the production of flooring materials, wall panels, furniture, countertops, and the like. The membrane is applied to a transfer film, which transfer film can be removed at any time prior to, or after the pressing operation. The panels produced have a durable but elastic surface which can protect the surfaces of the panel construct. The elastomeric covering on the panel construct also preferably provides a surface which is abrasion resistant, and provides better acoustical properties while providing a soft touch haptic surface.

A method of producing a moulded article comprising a thermoset polymer and particles of porous natural materials, such as wood materials, and uses thereof. The composite material has a continuous matrix of a hardened thermoset polymer and, distributed within the matrix, and the particles are at least partially encased by the thermoset polymer. The method comprises the steps of providing a mould with two opposite pressing surfaces, said pressing surfaces defining a space between them; feeding particles of porous natural materials into the space between the pressing surfaces; advancing the surfaces towards each other to compress the particles in said space; feeding unhardened thermoset resin in liquid form into the mould so as to fill at least said space between pressing surfaces while keeping the particles compressed between the pressing surfaces; and curing the thermoset resin in the mould to provide a moulded composite article.

The present disclosure is directed to molded door skins and methods of making. Methods include providing an at least partially consolidated flat wood composite blank. Methods further include positioning a stretchable film on an outer surface of the blank, and pressing the blank and the stretchable film together in a heated press to form the molded door skin. The molded door skin has a first surface and a second surface recessed relative to the first surface by a predetermined distance. A third planar portion extends between first and second planar portions at an angle in a range of 100 degrees and 120 degrees. Cracks or voids formed in the outer surface of the blank during the pressing are filled with the stretchable film such that an outer surface of the molded door skin is substantially or entirely crack and void free.

The present invention relates to a method of manufacturing a cellulose product having a flat or non-flat product shape by a pressure moulding apparatus comprising a forming mould. The forming mould has a forming surface defining said product shape, The method comprises the steps of:

arranging a cellulose blank containing less than 45 weight percent water in said forming mould; heating said cellulose blank to a forming temperature in the range of 100° C. to 200° C.; and pressing said cellulose blank by means of said forming mould with a forming pressure acting on the cellulose blank across said forming surface, said forming pressure being in the range of 1 MPa to 100 MPa.

A recycled board manufacturing method including a fibrous material generation process of generating a fibrous material by grinding recovered goods containing fibers into a fiber form, an adhesive application process of applying an adhesive having thermosetting properties to the fibrous material generated in the fibrous material generation process, a molding process of molding the fibrous material applied with the adhesive in the adhesive application process into a board shape, and a pressing-heating process of pressing and heating the fibrous material molded into the board shape in the molding process.
