The present invention relates to a method of producing a glued wood product for use in construction, comprising the steps of: providing at least two wooden pieces each piece comprising at least one joining face; creating a groove in at least one of said joining faces where the groove is arranged between a pair of peripheral edges; applying adhesive onto at least one of the joining faces of at least a first of said two wooden pieces; arranging said first wooden piece so that the joining face which comprises the applied adhesive meets a corresponding joining face of said second wooden piece, wherein at least one of said two joining faces comprises said groove; pressing the two joining faces towards each other so that the adhesive is compressed between said two wooden pieces, and maintaining said pressing for a sufficient time to bond the wooden pieces to each other; wherein the applied pressing force is strong enough to force the wood tissue to collapse at a contact area until the pressure force is transmitted primarily through the adhesive, wherein said contact area is defined by the surface area whereat the two joining faces of said wooden pieces contact each other upon being pressed together.

The present invention discloses a polyimide-based composite carbon film with high thermal conductivity and a preparation method therefor. The preparation method includes: uniformly coating the surface of a polyimide-based carbon film with an aqueous graphene oxide solution, and then covering the same with another polyimide-based carbon film uniformly coated with an aqueous graphene oxide solution; repeating such operation; after the polyimide-based carbon films are dried, bonding the polyimide-based carbon films by means of graphene oxide so as to form a thick film; bonding the polyimide-based carbon films more tightly by means of further low-temperature hot pressing; and finally, obtaining a thick polyimide-based carbon film with high thermal conductivity by repairing defects by means of low-temperature heating pre-reduction and high-temperature and high-pressure thermal treatment. The thick polyimide-based carbon film with high thermal conductivity has a thickness greater than 100 μm and an in-plane thermal conductivity of even reaching 1700 W/mK or above.

In-line systems and in-line methods are described that can be used to provide lightweight reinforced thermoplastic composite articles that include a textured or an embossed film layer. The textured or embossed film layer can provide one or more of water resistance, flame retardancy, a desired surface roughness, enhanced peel strength, enhanced acoustic absorption or other desired properties. The lightweight reinforced thermoplastic composite articles that include a textured or an embossed film layer can be used in building applications, in recreational vehicle applications and in other applications as desired.

Proposed are an eco-friendly automotive interior part, a method of manufacturing the same, and a method of designing the same automotive interior part. The automotive interior part can not only optimally correct physical properties thereof using manufacturing and design methods, but also have eco-friendliness by significantly reducing harmfulness to the human body due to the minimized use of chemicals, while realizing natural wrinkles resembling those of natural leather.

The present disclosure relates to a method to produce a coating layer, including applying a coating composition on a surface of a carrier, curing the coating composition to a coating layer, and subsequently applying pressure to the coating layer. The disclosure further relates to a method to produce a building panel, and such a building panel, and to a method to produce a coated foil, and such a coated foil.

A method for making a laminated glazing panel is described. A bolt having a head portion and a stem portion extending therefrom is positioned in a hole in a sheet of glazing material so that a first surface of the head portion is faces in the direction of a first major surface of the sheet of glazing material and the stem portion extends beyond a second major surface of the sheet of glazing material. A sheet of adhesive interlayer material is positioned on the first major surface of the sheet of glazing material to cover the first surface of the head portion. Suitable lamination conditions are used to laminate the sheet of adhesive interlayer material to the sheet of glazing material. During lamination, fluid trapped between the first surface of the head portion and the sheet of adhesive interlayer material is removed via a fluid pathway associated with the stem portion. Laminated glazing panels made using the method are also described.

An acidic gas separation membrane sheet causes an acidic gas to selectively permeate therethrough. The acidic gas separation membrane sheet includes a first porous layer, a hydrophilic resin composition layer, and a second porous layer in this order. A second peel strength between the second porous layer and the hydrophilic resin composition layer is less than a first peel strength between the first porous layer and the hydrophilic resin composition layer. An average value of the second peel strength is within a range of greater than or equal to 5 N/m and less than or equal to 500 N/m.

The invention relates to a bamboo floor, in particular to a composite bamboo floor. The composite bamboo floor comprises a floor surface board provided with a body, a pressed surface, a connecting surface connected with the core board, at least one cut surface board side face and surface board end faces, and the core board arranged under the floor surface board and provided with a core board surface connected with the floor surface board, a core board bottom surface, core board side faces and core board end faces, and the positions of the core board side faces or the core board side faces and the surface board side faces are provided with notch structures processed in two sides in the length direction of the composite bamboo floor. The composite bamboo floor is high in strength, high in processing efficiency and low in production cost.

A large number of green veneers for plywood respectively having high water contents and formed in a rectangular shape are vertically laminated to obtain a veneer laminate having a quadrangular prismatic shape. The veneer laminate is located between upper and lower platen members so that two opposite side faces of the veneer laminate vertically form cut face gathering planes. The upper and lower platen members are moved toward each other to apply a pressing force to the veneer laminate. The pressing force applied to the veneer laminate is released or weakened while the water drawn through the cut face gathering planes by the pressing force is dripping downward along the cut face gathering planes of the veneer laminate vertically formed.
