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.

A sheet manufacturing apparatus that shortens the time until the apparatus stops is provided. The sheet manufacturing apparatus has a sieve unit having at least part of material defibrated in a defibration process introduced thereto, moving at a first speed, and passing defibrated material through multiple openings disposed in the main section thereof; and a forming unit forming a sheet using precipitate that past through the openings of the sieve unit; the sheet manufacturing apparatus stopping the sieve unit with defibrated material that was introduced stored inside the sieve unit when production by the sheet manufacturing apparatus stops.

A method of manufacturing a composite article includes providing a polishing pad; rubbing over the polishing pad to produce a polishing pad debris; collecting the polishing pad debris; providing a wood material; and applying a force over the wood material and the polishing pad debris to form the composite article, wherein the composite article includes the wood material and the polishing pad debris, and the rubbing of the polishing pad includes removing a portion of the polishing pad to produce the polishing pad debris.

A novel oriented strand board (OSB) may be provided comprising recycled wood flakes that have been obtained by flaking of recycled wood at least in a core layer. A process may be provided for producing a corresponding oriented strand board. An apparatus may be provided by which the oriented strand board can be produced.

A method for producing a hydrophobic element is disclosed and includes the following steps: a) preparing a mixture of water and an organic material from sustainably renewable resources, b) moulding the mixture prepared in step a) to obtain a moulded element, c) drying and densifying the moulded element obtained in step b) to obtain a dried and densified element-, and d) impregnating to the core the dried and densified element obtained in step c) with a binder composed of organic materials from sustainably renewable resources. A covering hydrophobic element containing more than 90%, and preferably more than 99%, of an organic material from sustainably renewable resources is also disclosed.

The invention concerns an extruded composite containing wood fibre material and polymer. The wood fibre material is wood material where the knot or branch content is at least 10 w-%, or bark, or would material into which extract material obtained by extracting knots, branches or bark has been absorbed. The amount of the polymer is 5-25% from the weight of the composite. The composite has high hardness, and reduced moisture absorption and swelling properties. It can be used as constructional material.

Composite cellulosic products and processes for making same. In some embodiments, the composite cellulosic product can include a plurality of cellulosic substrates and an at least partially cured binder. Prior to curing, the binder can include a mixture formed by combining magnesium oxide, water, and magnesium chloride. A weight ratio of the magnesium oxide to the magnesium chloride in the binder can be at least 2.2:1 to 8.5:1.

A panel including a first layer including fragments from a first blend of paper fragments of a first size and plastic fragments of a second size, a second layer including fragments from a second blend of paper fragments of a third size and plastic fragments of a fourth size, the third size being different from the first size, and the fourth size being different from the second size, and a third layer comprising fragments from the first blend. The second layer is disposed between the first layer and the third layer.

A method of manufacturing a composite article includes providing a polishing pad; rubbing over the polishing pad to produce a polishing pad debris; collecting the polishing pad debris; providing a wood material; and applying a force over the wood material and the polishing pad debris to form the composite article, wherein the composite article includes the wood material and the polishing pad debris, and the rubbing of the polishing pad includes removing a portion of the polishing pad to produce the polishing pad debris.

A method of manufacturing a flame-retardant heat insulating formed product in the shape of a mat includes pouring water in used paper or a pulp material to defibrate and obtain defibrated cotton. A flame retardant such as a boric acid is charged into the defibrated cotton. By stirring and heating, a flame-retardant heat insulating defibrated cotton is obtained. Short fibers with a low melting point made of polyester or the like are charged into the flame-retardant heat insulating defibrated cotton. By mixing and stirring, a flame-retardant heat insulating loose material is obtained. A forming die made of corrugated cardboard provided with a lid having air vents is filled with the flame-retardant heat insulating loose material. The flame-retardant heat insulating loose material together with the forming die are heated with a microwave heating apparatus to form. A mat-shaped formed product is removed from the forming die.
