Abstract:
A metalworking oil composition contains: a component (A) that is an ester of a polyhydric alcohol and a fatty acid; and a component (B) that is elemental sulfur, in which the metalworking oil composition has a kinematic viscosity at 40 degrees C. in a range from 5 mm2/s to 70 mm2/s and a flash point of 200 degrees C. or more. The metalworking oil composition of the invention is suitably usable particularly in a field of a high-speed cutting work
Abstract:
A process for the in-situ formation of a lubricating phase comprising sulphur and tin in a friction material, wherein reaction of a sulphur source with a tin source in said friction material results in the formation of said lubricating phase, and wherein said reaction is initiated or effected by heat resulting, in use, from the generation of friction, wherein said sulphur source is selected from one or both of sulphur and/or a metal sulphide selected from one or more of iron, copper, zinc, titanium and bismuth, and wherein said tin source is selected from one or more of tin, a tin-containing compound and/or a tin-containing alloy.
Abstract:
This invention relates to a cost effective process for preparing a corrosion inhibitor/metal passivator additive for lubricant, grease and fuel applications from waste refinery streams, comprising reacting 2,5-dimercapto-1,3,4-thiadiazole either in powder form or in solution form in polar organic solvent, with disulphide oil obtained from Merox extraction/caustic wash of the refinery streams, in the presence or absence of redox agent.
Abstract:
The shortcomings inherent in prior art coupling fluids are eliminated by combining 1) a polyorganosiloxane fluid as the base oil with 2) sulfur or certain sulfur compounds and 3) at least one cyclic organosiloxane. These three ingredients form a suitable coupling fluid for use in viscous coupling systems.
Abstract:
There are provided a process for preparing a suspension of elemental sulfur in a fluid, a process for preparing a sulfurized cutting fluid, and products that are obtained from the processes. A high-shearing mechanical device is employed in either process to transform an unfinished suspension of sulfur in a fluid into a stable suspension of finely-divided sulfur.
Abstract:
A metalworking composition and an additive for a metalworking composition which imparts extreme pressure, antiwear, and corrosion-inhibiting properties to the metalworking composition. The additive comprises a phosphate ester and a sulphur compound. The composition comprises the additive used in an oil-based vehicle.
