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.
Abstract:
The bearing material produced by impregnating in the porous metal or alloy layers, for example, copper or copper-like alloy layers formed by known means, for instance by sintering on the back of a metal plate such as steel, a composition containing 1 to 30% by volume of one or both of a lead-tin alloy, which contains 1 to 25% by volume of lead fluoride and 3 to 30% by weight of tin, and lead wherein the total of the said lead fluoride and lead is 2 to 35% by volume and, as the residual part, polytetrafluoroethylene (PTFE). The capacity of the bearing may be further improved by adding about 0.1 to about 5% by weight of at least one member of the additives consisting of molybdenum disulfide, tungsten disulfide, cadmium oxide, aluminium oxide, calcium fluoride, lithium fluoride, graphite, lead iodide, glass fibre, carbon fibre and phosphates. The bearing is especially suitable for being applied to the shock absorber of vehicles moving under changeable load.

PROBLEM TO BE SOLVED: To provide an aqueous coolant which hardly causes corrosion of a metal material to be cooled, while having high cooling performance.SOLUTION: The aqueous coolant is obtained by blending one or more inorganic acid salts selected from a carbonate, a hydrogen carbonate, a sesquicarbonate, a phosphate, a borate, a molybdate, and a tungstate with a metal corrosion inhibitor. The aqueous coolant of the present invention has high cooling performance and hardly causes corrosion of a metal material to be cooled. Therefore, the aqueous coolant of the present invention is suitable as a heat treatment oil or a cutting oil.
Abstract:
An aqueous lubricant used for plastic working of metallic material which comprises (A) a water soluble inorganic salt, (B) lubricative agent selected from molybdenum disulfide and graphite and (C) wax, wherein the components are dissolved or dispersed in water, and wherein a concentration ratio (weight ratio) of (B) /(A) is in the range of 1.0 SIMILAR 5.0 and (C) / (A) is 0.1 SIMILAR 1. 0. And a method of lubricative film processing on a metallic material, in that the lubricative film formed by applying the aqueous lubricant is in a dried weight of 0.5 SIMILAR 40g/m . A water soluble inorganic salt (A) is preferably selected from the group consisting of a sulfate, a silicate, a borate, a molybdete and a tungstate. The wax (C) is preferably a natural wax or a synthetic wax which is dispersed in water and has a melting point of 70 SIMILAR 150 DEG C. The aqueous lubricant can be used for imparting excellent lubricity with ease to the surface of a metal having no chemical conversion layer formed thereon.
