Process for producing fibrous board
An object of the present invention is to provide a process for producing fiberous board with which fiberous board exhibiting high bending strength and high stiffness at a wide range of heating temperatures and a wide range of compressing and heating times. In the present invention, fiberous board having an initial flexural modulus of at least 300 MPa in three point bending test is obtained by forming a web by correcting sheath-core composite fibers of which a core component is formed from a copolymer of ethylene glycol and terephthalic acid and the sheath component is formed from ethylene glycol, adipic acid, terephthalic acid, isophthalic acid; and/or diethylene glycol. The web is then compressed in a direction of thickness and heated, so that the sheath component softens and melts and the sheath-core composite fibers are melt bonded together and molded into a flat plate shape.
Sheet manufacturing method
A sheet manufacturing method includes a mixing step of mixing a fiber and a resin powder in air, and a sheet forming step of accumulating and heating a mixture mixed in the mixing step to form a sheet. The resin powder has a volume average particle diameter of equal to or less than 50 μm, and an absolute value of an average charging amount in a range of 5 (μC/g) to 40 (μC/g).

Method and apparatus for producing a board
A method of producing a board for production of panels is provided comprising: providing particulate material comprising or consisting of particulate wooden material, producing glued particulate material by applying an adhesive to the particulate material, forming a spreading material mat by homogeneously spreading the glued particulate material onto a conveyor on which the spread glued particulate material is conveyed in a conveying direction, and producing a board by pressing the spreading material mat. A reinforcement material is applied to the spread glued particulate material parallel to the conveying direction during forming the spreading material mat and/or after forming the spreading material mat before any pressing of the spreading material mat such that the spreading material mat has at least one longitudinal reinforcement zone containing the reinforcement material. Boards can be obtained from which panels can be produced which have reinforced longitudinal and/or transversal edges.

ENERGY-STORING TEMPERATURE CONTROL MATERIAL AND PREPARATION METHOD AND APPLICATION THEREOF
The present invention provides an energy-storing temperature control material, and belongs to the technical field of temperature control materials. In the energy-storing temperature control material provided in the present invention, the organic synthetic fiber based phase-change material has a three-dimensional dispersion effect, and can form a network constraint for remaining phase-change materials to reinforce mechanical properties of the materials, thereby fixing shapes of the materials and avoiding a liquid-crystal phase separation phenomenon in the phase-change process. The phase-change energy storage agent can absorb and release the heat by means of solid-liquid phase conversion of the material, to achieve the temperature control effect; and the phase-change temperature regulator can regulate a phase-change temperature range of the phase-change material, to make the energy-storing temperature control material suitable for climatic features of northern China.
THERMALLY MODIFIED COMPOSITE WOOD-STRAND PRODUCTS FOR CONSTRUCTION AND OTHER APPLICATIONS
Improved wood strand panels suitable for construction are produced by first thermally modifying a plurality of wood strands that are thin in terms of thickness. Then, wood veneers are constructed from the thermally modified wood strands, at least some of which partially overlap one another. The wood veneers are on the order of 0.125 to 0.25 inches thick. Finally, the wood veneers, constructed from the thermally modified wood strands, are stacked on top of one another and connected using adhesive, pressure and temperature similar to plywood or LVL manufacture. The thermal modification and use of thin strands, followed by veneer formation, prior to manufacture of the composite results in a composite with uniform density, high-strength, resistance to decay, resistance to water sorption, and other benefits.
