    摘要： Strukturiertes Schleifmittel (6) sowie Verfahren zu dessen Herstellung, wobei das Verfahren die folgenden Schritte aufweist: a) Bereitstellen einer bahnförmigen Unterlage (1), b) Bereitstellen einer Bindemittel-Korn-Mischung (15), c) Auftragen der Bindemittel-Korn-Mischung als konvexe Anhäufungen (2), z.B. Halbkugelstrukturen, durch ein Siebdruckverfahren auf die bahnförmige Unterlage als Schleifschicht (18), wobei Freiflächen (21) auf der bahnförmigen Unterlage verbleiben und d) teilweises oder vollständiges Härten der aufgetragenen Bindemittel-Korn-Mischung durch Strahlungsenergie (13), so dass das strukturierte Schleifmittel eine bahnförmige Unterlage und eine Schleifschicht aufweist, wobei die Schleifschicht ausgehärtete konvexe Anhäufungen, aus einer Bindemittel-Korn-Mischung aufweist, und wobei auf der bahnförmigen Unterlage Freiflächen zwischen den konvexen Anhäufungen verbleiben.

    摘要： Provided are multilayered abrasive articles that include an abrasive composite having shaped features, a carrier film, and a nonwoven web, where the nonwoven web and the carrier film have respective patterns of discrete, three-dimensional protrusions that are aligned with each other. A compressible foam backing extending across a major surface of the nonwoven web opposite the carrier film. Further provided are multilayered abrasive articles that include an abrasive composite, a carrier film, and a non-woven web. The nonwoven web and the carrier film have respective patterns of discrete, three-dimensional protrusions that are aligned with each other and the shaped features and the three-dimensional protrusions of the nonwoven web have an average diameter:average diameter ratio ranging from 1:50 to 1:5.

    摘要： Composition, apparatus, and methods of composition and apparatus manufacture, for sharpening a paper shredder blade. Composition includes grinding powder, thickening agent, and additive. The thickening agent may be a white oil, an animal oil, an vegetable oil, or a stearine wax. The additive may be an antirust powder, an antiwear powder, an antistatic powder, or an antioxidation powder. The grinding composition is dispensed into a polyethylene film, and sealed to form the grinding apparatus, as a grinding sheet or a grinding packet. A method for forming a grinding sheet includes selecting the constituent materials for a grinding composition; stirring the constituent grinding composition materials; heating the constituent materials to melting; mixing the constituent materials, while melting and intermixing; cooling and packaging the grinding composition to form a grinding sheet or packet.

    摘要： An abrasive belt having a backing and an abrasive layer adhered to the backing by a make coat resin and the abrasive layer comprising a plurality of shaped abrasive particles. A first belt side and a second belt side opposing the first belt side with the first and second belt sides generally aligned with a longitudinal axis of the grinding belt. The belt having at least 30% of the shaped abrasive particles in the abrasive layer having a first face and placed onto the backing such that an angle between the first face and the longitudinal axis is greater than 0 degrees and less than or equal to 20 degrees.
