摘要： A reusable, fiber containing pulp product is described that is highly suited for use in the manufacture of paper products. The reusable, fiber containing pulp product provides a mixture of fibers and small, dense polymer/particle fragments. The polymer/particle fragments within the reusable, fiber containing pulp product have a size range and density that facilitates efficient removal of the polymer/particle fragments using pressure screens.

摘要： 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.

摘要： Unexpectedly unique and environmentally friendly composite material structures, storage articles fabricated therefrom, and related methods. The composite structure includes at least one or more fiber-containing layers, such as fiberboard or other layers having fibers from natural and/or synthetic sources, and one or more mineral-containing layers. The mineral-containing layer(s) comprises a thermoplastic bonding agent fixing the mineral particles in place. The fiber-containing layer(s) and mineral-containing layer(s) can be shaped, sized, and manufactured such that the composite structure formed therefrom is capable of being machined to form the storage article. The composite structure can be repulped and recycled without the use of dispersions, emulsions, or aqueous solutions. Further, the composite reduces layer mass requirements for heat seal, barrier, and fiber adhesion compared to polymer layers. The composite structure further has tensile strength and other structural characteristics that allow it to be readily machined into desired storage article forms.

摘要： An efficient method and apparatus for making a compressed structural fiberboard from agricultural fibrous matter. The method and apparatus provides a conveyor having variable drives for carrying the agricultural fibrous matter; a hopper having variable drives for conditioning and delivering the agricultural fibrous matter to an extruder; the extruder having a cyclic ram with linear actuators and a floating plate to drive the cyclic ram between an extended position, wherein the agricultural fibrous matter is compacted into the compressed structural fiberboard, and a retracted position, wherein the agricultural fibrous matter is delivered to the extruder; synthetic oil heaters for heating the compressed structural fiberboard; a heat sink track cooler for cooling the compressed structural fiberboard; and a water jet cutting system for cutting the compressed structural fiberboard into individual boards.

摘要： A process for producing a high utility wooden synthetic construction material, with a woodgrain appearance close to the texture of natural wood, which effectively uses waste in the form of a wood powder of plywood. A wood powder of plywood, manufactured by adding an adhesive to wood fibers or chips and pressurizing, and a thermoplastic synthetic resin are used as main raw materials. A material obtained by adding an auxiliary raw material to the main raw materials is heated and melted at 160° C. to 200° C., and then pelletized to obtain raw material pellets. The raw material pellets are loaded into an extrusion molding or an injection molding machine, without actively removing contained moisture derived from the wood powder of plywood and an adhesive component from the raw material pellets, heated and melted at 150° C. to 200° C., and extruded from the mold or injected into the mold.

摘要： A method of manufacturing a textured element may include (a) collecting a plurality of filaments upon a textured surface to form a non-woven textile and (b) separating the non-woven textile from the textured surface. Another method of manufacturing a textured element may include depositing a plurality of thermoplastic polymer filaments upon a first surface of a polymer layer to (a) form a non-woven textile and (b) bond the filaments to the polymer layer. A textured surface may then be separated from a second surface of the polymer layer, the second surface being opposite the first surface, and the second surface having a texture from the textured surface.
