Abstract:
The object of the present invention is to provide a water-base lubricating fluid or a water-base hydraulic fluid in place of an oily liquid which has been used as a lubricating oil or a hydraulic oil applied onto the operating part of a machine and a device. The lubricating fluid of the present invention comprises fluoride ion, hydrogencarbonate ion, and water-soluble alcohols or their derivatives.
Abstract:
PROBLEM TO BE SOLVED: To further enhance abrasion resistance and frictional characteristics of a sliding composition and a sliding member under a high PV value condition to fulfill the demand for further enhancement of abrasion resistance under the high PV value condition, though abrasion resistance and frictional characteristics of the sliding member have been heretofore enhanced by incorporating into a polytetrafluoroethylene as a base resin bismuth, an alkaline earth metal salt or the like instead of lead in consideration of the environment. SOLUTION: The sliding member excellent in abrasion resistance and frictional characteristics even when used under the high PV value condition comprises 50-80 vol% of a thermosetting resin as the base resin and, incorporated thereinto, 10-40 vol% of a PTFE having a molecular weight of at least 3,000,000 and 1-20 vol% of bismuth and/or a bismuth alloy.

Abstract:
A grease composition for high-temperature, high-speed and high-load bearings comprises (i) a lubricating base oil composed of an alkyldiphenyl ether lubricant as an essential ingredient and having a kinematic viscosity of 90-160 cSt at 40 DEG C., and (ii) 22-30 wt. %, based on the grease composition, of a diurea compound as a thickener. The diurea compound is represented by the following formula:bon group having 6-15 carbon atoms, R1 and R3 denote an aromatic hydrocarbon group having 6-12 carbon atoms or a linear alkyl group having 8-20 carbon atoms, and the proportion of aromatic hydrocarbon groups in R1 and R3 is 70-95 mole %. The NLGI thickness grade of said composition is in a range of from No. 1 to No. 3.
Abstract:
PURPOSE: To provide a water-soluble lubricant for metal working consisting mainly of disodium hydrogenphosphate and a fluorohydrocarbon-based nonionic surfactant and exhibiting excellent lubricating property and rust prevention on metal without causing enviromental pollution. CONSTITUTION: The lubricant consists mainly of disodium hydrogenphosphate and a fluorohydrocarbon-based nonionic surfactant and preferably contains sodium metavanadate and/or sodium molybdate. For preparation, disodium hydrogenphosphate and the surfactant are dissolved in water to produce a liquid lubricant, or the latter is absorbed by the former, or alternatively an aqueous solution containing the two components is condensed to produce a lubricant in powder.
