Abstract: Abrasive devices suitable for use in cylinder style floor cleaning machines for the purpose of deep cleaning, restoring, honing and/or polishing are described. The abrasive devices include an elongated body and abrasive structures extending, at least in part, radially outward from an outwardly facing body surface, and relative to a rotational axis of the elongated body.

Abstract: A composite board having a sorghum stalk material component and a thermoplastic binder component is disclosed together with a corresponding method of manufacture. To prepare the composite board, the sorghum stalk material is harvested, dried and refined into fibers, particles or slit-stalks. In some cases, the stalk material is first combined with a thermosetting binder such PMDI. Next, the stalk material is arranged into one or more layers and then combined with a thermoplastic binder, such as HDPE film, in a stack. In some instances, recycled HDPE may be used. The stack is thermocompressed in a press at a preselected temperature to compress the sorghum and thermoplastic binder to a preselected board thickness. The board is then cooled to below the softening temperature of the thermoplastic resin. After cooling, the board can be cut or trimmed to its final desired dimensions.

Abstract: Composite panels and pulp, and paper products of the pulp, are produced from Arundo donax. In the fabrication of the composite panels, Arundo donax is comminuted to a suitable size, combined with a binder, and consolidated into panels that meet standards for construction and/or furniture grade panels. The Arundo donax particulates may be combined with wood particulates to produce a mixed furnish that can be used in the preparation of composite panels. Comminuted Arundo donax is treated, in conventional pulping processes, to produce a high tensile strength pulp that can be used in the production of paper. The pulp has a lighter color than wood pulp, and thereby uses less bleaching chemicals to achieve a desired whiteness. The pulp can be combined with wood pulp to produce a variety of products.
