The present disclosure relates to the technical field of resource recycling and provides a processing method for a waste oriented strand board and waste oriented wood chips, and an oriented strand board preparation method thereof. The processing method for a waste oriented strand board provided in the present disclosure includes the following steps: softening a waste oriented strand board to obtain a softened waste oriented strand board; and flaking the softened waste oriented strand board pieces using a disc flaker to obtain waste oriented wood chips. According to the present disclosure, the waste oriented strand board is softened first to be chipped readily. It is specified in the present disclosure that the disc flaker is used such that relatively intact wood chips can be obtained.

Provided is a strand board with improved strength and water resistance. Reduction in productivity is prevented and characteristics of the strand board can be varied as desired while achieving certain strength and water resistance of the strand board. A strand board B is formed by stacking and laminating five strand layers 1 each formed by a large number of strands 5. The strand board B has substantially constant density distribution in the lamination direction of the strand layers 1. Three of the five strand layers 1 of the strand board B are high-density strand layers 1a having a higher density than the other strand layers 1, and the other strand layers 1 are low-density strand layers 1b.

Sheet, board or panel, in particular an OSRB (1)—Oriented Structural Reed Board—comprising a layer of material (2) made up of pressed reeds having a multiplicity of stems which are split predominantly longitudinally, so that it is also the case that the insides of the stems, at least in part, are accessible to a binder, wherein the binder is able to hold together the reeds for forming a solid sheet, board or panel. It is thus possible to provide a biocomposite sheet, board or panel based on sustainable raw materials which has improved properties and strength and requires only a particularly low level of production outlay. A further aspect of the invention relates to a method for producing an OSRB (1).

A system for production of panels, particularly for the production of panels made of wood flakes comprising at least a support plane movable along a direction of forward movement, at least a first and a second forming machine arranged in succession to one another along the direction of forward movement above the support plane and each comprising at least a first set of distributor elements rotatable around respective axes, the distributor elements being able to select a flow of wooden material comprising short flakes and long flakes so as to allow the fall of the short flakes on the support plane and the dragging of the long flakes, where the first forming machine and the second forming machine comprise at least a second set of distributor elements operable independently of the relative first set and where the distributor elements of the first set are operable in rotation in both directions.

System and method for manufacturing bamboo dimensional lumber having cross-hatched fiber layers. The method involves splitting bamboo poles into smaller slats, which are then and crushed into fibers. These fibers are covered with glue, and laid in alternating perpendicular layers. The combined layers are hot pressed to form a rough lumber board composed of cross-hatched bamboo fiber layers. The board is then cut to any desired dimensions for lumber.

Structural panels include a plurality of structural layers adhered together in a laminate, including a plurality of bamboo structural layers and at least one non-bamboo structural layer disposed between a first bamboo structural layer and a second bamboo structural layer of the plurality of bamboo structural layers. The first bamboo structural layer and the second bamboo structural layer of the plurality of bamboo structural layers are spaced apart by the at least one non-bamboo structural layer on opposite sides of a neutral plane extending through a center of the structural panel and parallel to the plurality of bamboo structural layers. Structural sections including wall sections, roof sections, and floor sections include one or more structural panels.

Provided herein are lignocellulosic composite articles and methods for forming the same. In an aspect, the lignocellulosic composite articles comprise a plurality of lignocellulosic pieces derived from wood; together with an adhesive system disposed on the plurality of lignocellulosic pieces for bonding the plurality of lignocellulosic pieces. In an aspect, the adhesive system comprises a binder component comprising diphenylmethane diisocyanates (MDIs) and/or polymeric diphenylmethane diisocyanates (pMDIs), and a catalyst component comprising imidazole in a water solution.

A process for producing a smooth-sided strand-based siding or wood structural panel using a pre-telegraphing process. The pre-telegraphing is performed after the primary process completes pressing and consolidation of the substrate/board. The pre-telegraphing process applies a water spray on the hot board immediately out of the primary process press, and before overlay application. The application of the water spray causes the surface of the board to swell and cure. A settling period follows to allow the top surface particles and strands to swell along with absorption and evaporation of the moisture. This is followed by surface sanding to remove the telegraphing and produce a smooth surface. This may then be followed by lamination of overlay(s). The process is completed by post-lamination treatment and coating of the board.
