摘要:
An aqueous hydraulic fluid composition comprising (i) a salt of formic acid, and (ii) one or more lubricants such as a monovalent metal salt, ammonium, or amine salt of a dicarboxylic acid, is described in which the aqueous hydraulic fluid composition demonstrates increased thermal stability when exposed to elevated temperatures for a prolonged period of time while being able to tolerate the presence of 10% v/v synthetic seawater. The aqueous hydraulic fluid composition contains less than about 20% by weight (preferably none or substantially none) of an oil selected from the group consisting of mineral oils, synthetic hydrocarbon oils, and mixtures thereof. The hydraulic fluid preferably contains no glycols in some embodiments. The pH of the hydraulic fluid is preferably from 8 to 10 and is maintained by a buffer which preferably comprises borax in some embodiments.

Provided is a water-based lubricating coating agent from which a lubricating coating film which has excellent corrosion resistance, workability, and film removability in practical use is obtained. A water-based lubricating coating agent characterized in that a water-soluble silicate (A) and at least one water-soluble inorganic salt (B) selected from the group consisting of a tungstate, a phosphate and a borate are blended such that the solid content mass ratio (B)/(A) falls within the range of 0.7 to 25.

摘要:
The present invention provides a thermally conductive grease composition which scarcely increases in hardness during high-temperature heating and has a minimized reduction in growth, containing: (A) an organopolysiloxane including at least two alkenyl groups per molecule, the 25°C kinetic viscosity being 5,000 to 100,000 mm 2 /s; (B) a hydrolysable methyl polysiloxane, trifunctional at one terminus, represented by general formula (1)
(R 1 is a C 1-6 alkyl group, and a is an integer 5 to 100); (C) a thermally conductive filler having a thermal conductivity of 10 W/m·°C or greater; (D) an organohydrogenpolysiloxane containing two to five hydrogen atoms directly bonded to a silicon atom (Si-H group) per molecule; (E) an adhesion promoter having a triazine ring and at least one alkenyl group per molecule; and (F) a catalyst selected from the group consisting of platinum and platinum compounds.
摘要:
Provided is a grease composition that has high lubricity, particularly excellent wear resistance, and shows only a small extent of deterioration in wear resistance with long-term use under high temperatures. The grease composition comprises at least one base oil selected from a mineral oil-based lubricant base oil and a synthetic lubricant base oil, an amide compound, a solid lubricant, and a urea-based thickener, wherein the amide compound is heated and melted at least once with the base oil.
摘要:
[Problems] To provide a lubricating coating agent for plastic working, containing a non-black solid lubricating material, and a metal material coated with the agent, which enable highly difficult forging that has been conventionally difficult to practically apply to anything except lubricating coating films containing a black solid lubricant typified by molybdenum disulfide [Means for solving] The problems can be achieved by means of a lubricating coating agent for plastic working, which is characterized by containing, at 5 mass% or more in terms of solid content ratio in a coating film, a calcium sulfate hydrate with a particular scale-like crystal shape among calcium sulfate hydrates deposited by reacting a sulfuric acid or a sulfate with a calcium compound in water, and a metal material coated with the agent.
