[Problem]To provide a ply adhesive that is capable of expressing a sufficient ply adhesion strength, does not harden an area where the ply adhesive is applied, and does not worsen paper texture. [Solution] The problem can be solved by a ply adhesive that comprises: 1-5 mass% of carboxymethylcellulose, a 1 mass% aqueous solution of said carboxymethylcellulose having a viscosity of 100 mPa.s or lower, as an adhesive; and 1-5 mass% of at least one member selected from among propylene glycol, glycerol and butylene glycol as a softening agent.

Disclosed herein is a humidifying medium which adopts a natural humidifying system and has excellent lifespan characteristics. The humidifying medium according to the present invention is formed by coupling a linerboard to one or both sides of a corrugated board. The corrugated board and the linerboard have different average pore diameters, and the humidifying medium of the present invention may be formed by coupling a linerboard having an average pore diameter of 35-40 µ m to one or both sides of a corrugated board having an average pore diameter of 8ˆ¼10 µ m.

The invention relates to a laminate (1), in particular for manufacturing a construction panel, consisting of a combination of at least one carrier material layer (2) made of a non-flammable non-woven (4) impregnated with a resin (3) and at least one decorative material layer (5) made of a decorative paper (7) that is impregnated with a melamine formaldehyde resin (6) and is optionally dyed and/or printed. The invention further relates to a method for manufacturing a disclosed laminate (1) and especially a construction panel.
摘要:
The present invention relates to a process for producing at least one ply of a paper or paperboard product which process comprises the steps of; subjecting cellulosic fibers to heat treatment wherein the fibers are treated at a high dry content and at an increased temperature, preparing a slurry comprising said heat treated fibers, forming a web of said slurry and, dewatering said web whereby a ply of said product is formed. The present invention further relates to a paper or paperboard product produced according to the process.
摘要:
The invention refers to a corrugated board comprising at least one liner, preferably at least two liners (1,2), and at least one fluting (10), wherein each fluting (10) is located on one adjacent liner, preferably between two adjacent liners (1,2), wherein the at least one fluting (10) forms a trapezoidal profile in a machine direction (x-direction) comprising straight sections (12) running basically parallel to the adjacent liner (1,2) which alternate with inclined sections (13) running inclined with regard to the adjacent liner (1,2). In order to enhance the mechanical properties of the corrugated board the straight sections (12) and the inclined sections (13) of the fluting comprise a waviness in a cross direction (y-direction) transversal to the machine direction (x-direction) and a thickness direction (z-direction) such that the width of each straight section (12) periodically varies between a minimum value (I min ) and a maximum value (I max ).
