A plank has a first portion with at least three layers. The first layer is of a plant material, and has an inner surface that includes a nonwoven fabric or a fiberglass mesh. The second layer is of an adhesive paper material that includes a macromolecular glue where the macromolecular glue is 50-55% melamine, 35-40% plasticizer, and 3-5% formaldehyde. The third layer is one of bamboo, wood, or paper. The plank has a second portion, which may be of a plastic composite base material or a magnesium oxide composite base material. When the second portion is of a plastic composite material, the first portion is fused to the second portion by cold pressing or a polyurethane reactive adhesive. When the second material is of a magnesium oxide composite base material, the first portion is thermally pressed to the second portion by cold pressing, hot pressing or a polyurethane reactive adhesive.

Examples described herein relate to a molded article provided with a resin part formed with a polyolefin resin composite material, the polyolefin resin composite material containing a polyolefin resin and 10 to 150 parts by mass of cellulose based on 100 parts by mass of the polyolefin resin, wherein an area of an aggregate of the cellulose is less than 20,000 m.sup.2.

A method of manufacture of medium and high density fibreboard with moisture and mildew resistance and low formaldehyde emission, which includes the steps of: (a) providing wood chips; (b) pre-steaming; (c) refining the wood chips into fibers and adding 250-800 kg/m.sup.3 urea-formaldehyde resin adhesive, mildew inhibiting agent, fireproof bonding agent, nigrosine solution with a mass percentage of nigrosine in absolutely dried fiber of 1-1.2%, 6-8 kg/m.sup.3 refined paraffin and 1.5-2 kg/m.sup.3 curing agent; (d) feeding activated carbon of 100-200 mesh to mix with the fibers and then drying the fibers to a water content between 8-10%; (e) separating qualified fibers to measuring silo; (f) laying the fibers onto a mat formation platform uniformly to form a fiber mat by pre-pressing; (g) pre-heating the fiber mat; and (h) processing continuous hot-pressing to form a raw board. The resulting fiberboard is black in color, has good physical properties and low formaldehyde emission rate.

The disclosure relates to a method for producing a wood material panel with at least one layer with an inhomogeneous density profile, including the steps: scattering a multitude of wood particles to produce a particulate cake, pressing the particulate cake to form a layer of the wood material panel, and scattering different pre-determined quantities of wood particles in at least two areas within the particulate cake.

A method of forming an article is provided. Multi-fiber cellulose strips are interacted with a bonding agent and layered in a plurality of layers, the layered cellulose strips collectively defining opposed major surfaces. A porous sheet member, interacted with a fire-retarding solution, is engaged with one of the major surfaces of the layered cellulose strips, to substantially cover the major surface. The porous sheet member is disposed adjacent to a substantially smooth and uniform surface, and layered cellulose strips and the porous sheet member collectively exposed to an actuating element, configured to actuate the bonding agent to react in a volumetrically-expensive reaction with the fire-retarding solution to facilitate cohesion between the layered cellulose strips and the porous sheet member to form a board member, wherein the porous sheet member conforms to the adjacent surface via the volumetrically-expansive reaction to define a substantially smooth and uniform surface of the board member.

A cloud-based system network for verifying and documenting prefabricating Class-A fire-protected wood-framed buildings produced from a prefabricated Class-A fire-protected wood-framed building factory system supporting multiple production lines for producing Class-A fire-protected wood-framed components including wall panels, floor panels, stair panels, floor trusses, and roof trusses for use in constructing custom and pre-specified prefabricated Class-A fire-protected wood-framed buildings. The system network includes (i) a data center with web, application and database servers for supporting a web-based site for hosting digital images of barcoded/RFID-tagged certificates attached to prefabricated Class-A fire-protected wood-framed building components, and other certification documents, and (ii) mobile smart-phones used to capture digital photographs and video recordings of Class-A fire-protected wood-framed building sections, and upload the captured digital images to the data center, for each prefabricated wood-framed building project, so that building purchasers, insurance companies, builders, architects and other stakeholders can review such certifications and documentations during the prefabrication of wood-framed buildings from the factory system.

The invention relates to a method for preparing a cold-pressing adhesive and a cold-pressing processing system for plant fiber boards. The fiber board processing method comprises the following steps of: firstly, mixing plant fiber and an adhesive, and fully and uniformly stirring the mixture; then paving the uniformly mixed plant fiber and adhesive in a cold-pressing die set of a cold-pressing device for cold-pressing and curing to prepare a plant fiber block; cutting the plant fiber block into a plurality of plant fiber board blanks with a required thickness; and finally conducting edge cutting and sanding treatment on the plant fiber board blanks to obtain the plant fiber boards.

The current invention concerns a method for producing an aqueous dispersion suitable for being used as a flame retardant additive to wood composite panels. At least one pH-regulator, at least one inorganic thickener, and optionally at least one smoke suppressing agent is added to a premix while maintaining the actuation of wet-milling systems until the dispersion is obtained.
