Abstract:
A rheologically controlled glass lubricant for hot metal working comprises a glass powder, a binder, a rheological agent, and a wetting and viscosity modifier. These materials may be dispersed in a carrier. The lubricant is made by mixing the constituent elements, milling the mixture, and stabilizing the milled mixture. The lubricant can be used in a forging operation by coating a metal part with the lubricant, heating the coated part, placing the coated heated part in a forge, and rapidly applying sufficient pressure to deform the coated metal part into a desired shape.
Abstract:
A water washable thermally conductive grease useful for thermal coupling of electronic chips and heat sinks in electronic modules comprises a hydrophilic liquid polymer carrier, an antioxidant, and up to 90 weight percent of a microparticulate thermally conductive filler. In a preferred embodiment, the thixotropic dielectric composition further comprises an ionic surfactant to promote wetting/dispersion of the microparticulate filler. The thermally conductive grease is non-corrosive, resistant to shear induced phase destabilization and capable of being washed from module surfaces with aqueous solutions. Substitution of the present hydrophilic based greases for art-recognized solvent washable greases eliminates use of non-aqueous solvents in electronic module processing/reprocessing operations.
Abstract:
An aqueous lubrication treatment liquid for a cold plastic working of a metallic material comprises 50 to 400 g/l of a solid lubricant, for example, MoS.sub.2, 1 to 40 g/l of a surfactant, 10 ppm to 5000 ppm, in terms of colloidal titanium compound, water, and optionally, 5 to 150 g/l of a binder and 4 to 160 g/l of a metallic soap. This liquid exhibits a strong bonding to the metallic material and an excellent lubricating property, and prevents rusting of the metallic material.
Abstract:
A solid lubricating material consisting essentially of an intimate mixture of about 15 to 50 mole percent molybdenum trioxide, balance molybdenum disulfide. This material is particularly useful under extreme environmental conditions such as very high temperature or vacuum. The material may be used in powder form, compacted into a pellet or other desired shape, incorporated into a grease composition or incorporated into a resin-bonded solid film lubricant.
Abstract:
An improved lubricating oil composition comprising a major amount of oil of lubricating viscosity; a minor amount by weight of solid particles effective to improve the lubricating properties of the composition; and a minor amount by weight of at least one of certain co-polymers derived from the polymerization of (1) an N-vinyl-pyrrolidone, and (2) an oil-soluble acrylic ester.An improved method for lubricating an internal combustion engine is also disclosed.
Abstract:
A LUBRICANT CONCENTRATE COMPOSITION WHICH COMPRISES FROM ABOUT 3 TO 75 PERCENT BY WEIGHT OF AN ALKALI METAL ORTHOPHOSPHATE, ABOUT 15 TO 97 PERCENT BY WEIGHT OF AN ALKALI METAL FATTY ACID SOAP, CONTAINING FROM ABOUT 8 TO 22 CARBON ATOMS, AND AT LEAST 0.1 PERCENT BY WEIGHT OF A SURFACE ACTIVE AGENT SELECTED FROM THE GROUP CONSISTING OF NON-IONIC ETHYLENE OXIDE-ALCOHOL CONDENSATES AND AMPHOTERIC BIODEGRADABLE SURFACE ACTIVE AGENTS. ADDITIONALLY, THE CONCENTRATE COMPOSITION MAY CONTAIN FROM ABOUT 0.1 TO 80 PERCENT BY WEIGHT OF A WATER DISPERSIBLE DILUENT SELECTED FROM WATER SOLUBLE AND COLLOIDALLY SUSPENDABLE DILUENTS, SUCH AS SUGAR AND POLYETHYLENE GLYCOL HAVING A MOLECULAR WEIGHT FROM ABOUT 100 TO 10,000. AN AQUEOUS LUBRICANT COMPOSITION CONTAINING FROM ABOUT 10 TO 400 POUNDS OF THIS CONCENTRATE PER HUNDRED GALLONS OF SOLUTION MAY BE USED TO FORM A LUBRICANT COATING ON A CHEMICALLY COATED METAL SURFACE, SUCH AS A PHOSPHATE COATED METAL SURFACE, WHICH SURFACE MAY THEN BE DEFORMED AFTER THE LUBRICANT COATING HAS BEEN DRIED.
Abstract:
Systems and methods are provided for block operation during lubricant and/or fuels production from deasphalted oil. During “block” operation, a deasphalted oil and/or the hydroprocessed effluent from an initial processing stage can be split into a plurality of fractions. The fractions can correspond, for example, to feed fractions suitable for forming a light neutral fraction, a heavy neutral fraction, and a bright stock fraction, or the plurality of fractions can correspond to any other convenient split into separate fractions. The plurality of separate fractions can then be processed separately in the process train (or in the sweet portion of the process train) for forming fuels and/or lubricant base stocks. The separate processing can allow for selection of conditions for forming lubricant fractions, such as bright stock fractions, that have a cloud point that is lower than the pour point.
