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 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.
