Abstract:
Ein Zuschlagstoff zur Beimischung in einen Betriebsstoff einer technischen Anlage, insbesondere in den Schmier- und Kraftstoff eines Verbrennungsmotors, soll auf vergleichsweise einfache Weise eine besonders günstige und zuverlässige reibungsvermindernde Behandlung von Oberflächen von in der technischen Anlage geführten Arbeitskomponenten ermöglichen. Dazu umfasst der Zuschlagstoff erfindungsgemäß die Komponente Eisen-Magnesium-Hydroxid-Silikat.
Abstract:
The aim of the invention is to obtain a lubricant containing a graphite and a phyllosilicate for lubricating two heated metal objects, in mutual contact through their surfaces, moving in relation to each other. Said lubricant contains, in relation to the solid material content, at least 5 wt. % of phyllosilicate containing water but free of alkali.
Abstract:
The present invention provides a water based friction control composition comprising a binder a rheological control agent, and optionally a lubricant. The liquid friction control composition may also comprise other components such as a wetting agent, a consistency modifier, and a preservative. The liquid friction control compositions may be used to modify the interfacial friction characteristics in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems. A method of reducing lateral force, reducing energy consumption, or controlling friction between a metal surface and a second metal surface by applying the composition to metal surface, for example a top of rail or wheel, is also provided. The composition may be sprayed onto the rail surface.
Abstract:
A multi-purpose thread compound comprises, dispersed in a supporting vehicle, an extreme pressure agent, and particulate material comprising graphite and a calcium and/or magnesium inorganic salt, wherein substantially all the particulate material in the composition has a particle size of no greater than 50 mu m.
Abstract:
A rolling bearing which has a satisfactory life at a low cost even under such service conditions that water is incorporated into a lubricant either externally or due to dew condensation, or that vibration has an influence, and is particularly suitable for electrical equipment and accessories of automobile engines, such as alternators. The hydrogen ion index pH of a grease sealed in the interior of the bearing is adjusted to 7 to 13. For attaining similar effects, the pH of the grease is adjusted to 5 to 13 when an organic metal salt or ADTC has been added in a predetermined amount to the grease, when an inorganic compound having an average particle diameter of not more than 2 mu m has been added in a predetermined amount to the grease, or when a diurea compound containing an aromatic amine or a mixture of diurea compounds has been added as a thickening agent to the grease.
Abstract:
The invention provides composites of organic polymeric compositions including a matrix of an organic polymer and a filler distributed throughout the matrix, the filler being present in the matrix substantially as separate particles, each about the fundamental particle size of the filler. The fillers are unique mixed metal hydroxide compositions that are obtainable in sub-micron size particles. These particles are layered and have a BET specific surface area in excess of about 100 m /g. An anion of the particulates is selected to be compatible with the organic polymer thereby providing ease of dispersion of the filler particles throughout the polymer matrix.
Abstract:
The pasty damping agent is used to damp mechanical and/or acoustic oscillations. The agent contains as a minimum compound a solid finely divided substance or a mixture of solid finely divided substances, as a liquid phase, a silicone oil, a polyglycol, a mineral oil and/or a saturated or aromatic aliphatic carbon dioxide ester, an agent for increasing the activity of the limit layer or a surfactant, a magnesium and/or aluminum silicate and/or a silicon dioxide finely divided as a viscosity stabilizer and possibly a small quantity of an empty oxidiser. The damping agent is used in different hydraulic damping devices or for industrial vibration shock absorbers.
