  • Patent number: 10240104
    Abstract: The invention concerns an agent for mixing into a service fluid for a technical layout, a concentrate for mixing into a service fluid for a technical layout, and a service fluid. An agent according to the invention contains at least one ingredient A chosen from the group of three-layer silicates, at least one ingredient B chosen from the group consisting of bentonites, pyrogenic silicic acids, and talc, and graphite. Thanks to an agent according to the invention, a concentrate according to the invention, and a service fluid according to the invention, the detachment of the lubricating film on the surfaces of working components of a technical layout that are moving relative to each other is prevented in a reliable manner. This is accomplished in particular by a smoothing of the surfaces, accompanied by a reduction of the frictional coefficient and the steady-state temperature of the working components.
