Abstract:
The present invention relates to a water soluble copper, copper alloys and non-ferrous metals intermediate cold and hot rolling composition comprising a base stock oil and, based on the total weight of the composition:—from 1 to 80% by weight of a combination of a monester of fatty acid with polyol and a tetraester of a fatty acid with pentaerythritol the weight monester:tetraester ratio of said combination ranging from 1:20 to 10:1; and—from 0.02 to 2% by weight of an azole derivative. The invention also relates to an oil-in-water emulsion, an intermediate cold rolling process, a hot rolling process and the use of the oil-in-water emulsion in an intermediate cold or hot rolling process.
Abstract:
According to the invention there is provided a liquid friction control composition characterized as either having a high and positive friction characteristic or a low and neutral friction characteristic, comprising a retentivity agent. The liquid friction control composition may also comprise other components such as a solid lubricant, a wetting agent, a consistency modifier, and a preservative. The liquid friction control compositions may be used to modify the interfacial friction characteristics in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems.
Abstract:
The disclosure relates to improved gel/grease compositions as well as grease compositions capable of imparting improved corrosion resistance. The grease includes a silica/silicate mixture that can imparts a relatively high pH and corrosion resistant properties to the grease.
Abstract:
According to the invention there is provided a liquid friction control composition with enhanced retentivity comprising an anti-oxidant. The liquid friction control composition may also comprise other components such as a retentivity agent, a rheological control agent, a friction modifier, a lubricant, a wetting agent, a consistency modifier, and a preservative.
Abstract:
According to the invention there is provided a method of reducing wear of one or both of two steel elements having surfaces in sliding or sliding-rolling contact. The method involves applying an HPF friction control composition to one, or more than one contacting surface of one or both of the two steel elements. In a particular example, the HPF friction control composition comprises a rheological control agent, a lubricant, a friction modifier, and one, or more than one of a retentivity agent, an antioxidant, a consistency modifier, and a freezing point depressant.
Abstract:
The disclosure relates to temporary corrosion resistant coatings and films upon metal substrates, e.g., metal tools and dies. The temporary coatings and films will not adversely chemically alter the surface of the underlying substrate. The coatings/films comprise a mixture of at least one of an acrylic, water, an oil, silica, at least one silicate, surfactants and optionally one or more buffering materials and waxes.
Abstract:
This invention is to provide a conductive grease which is less to decrease conductivity as a time passes. The conductive grease comprises abase oil, a thickener, a conductive solid powder, and at least one kind of a wear inhibitor, an extreme pressure agent and an oiliness agent, wherein an amount of the conductive solid powder added is 0.1 to 10 wt %, and an amount of the at least one kind of a wear inhibitor, an extreme pressure agent and an oiliness agent added is 0.1 to 10 wt %. Further, the conductive grease comprises the base oil and at least one of conductive additives, and the conductive additives are fibrous carbon, metallic particle, metallic compound particle and carbon nano-tube. The conductive grease to be packed into the rolling bearing comprises conductive fine particles such as carbon black and has an oil separation degree of 2% or lower. A ball bearing to be favorably used at high temperature comprises an inner race and an outer race, and a plurality of balls freely rotating between both races, and the conductive grease packed into a space defined between both races and holding the plural balls therein, and the conductive grease comprises the base oil, a thickener comprising fluorine compound or silicone compound and 0.2 to 10 wt % of the carbon black.
