Abstract:
A lubricant composition including ethoxylated long chain primary alcohols and, preferably, boron compounds but excluding most other previously used organic lubricant materials gives superior results in tube pointing operations, especially with thick walled tubes, and is also useful for drawing operations, either subsequent to pointing or independently of pointing, where very high quality surface finishes are desired.
Abstract:
A stearate free solid lubricant for cold working of metals contains approximately equal amounts of an alkene-acrylate ionomer and an alkoxylated alcohol in which the alcohol moiety has from 18-60 carbon atoms and the alkoxylate block has about the same number of carbon atoms. This lubricant can be conveniently applied from aqueous solution/suspension and works effectively even when the underlying steel surface has no conversion coating, which is usually required with stearate lubricants for best results.
Abstract:
A composition for lubricating a metal workpiece prior to cold forming consists essentially of: an aqueous alkaline stearate compound present in an amount sufficient to impart metal lubrication between about 180.degree. F. and about 320.degree. F.; an aqueous alkaline palmitate compound present in an amount sufficient to impart metal lubrication below about 160.degree. F.; an aqueous metallic stearate compound present in an amount sufficient to impart metal lubrication between about 320.degree. F. and 440.degree. F.; a polymeric glycol present in an amount sufficient to provide temperature stability, act as a carrier for the aqueous compounds, and impart a waxy lubrication to the metal; a compound present in an amount sufficient to act as a carrier for the aqueous compounds and to provide a translucent film barrier on the metal; an alkaline buffering agent present in an amount sufficient to provide dispersion, viscosity and stability; a hydrotropic agent present in an amount sufficient to solubilize the lubricating composition. A process is disclosed for lubricating a metal workpiece outer surface prior to cold forming, the process comprising the step of disposing a non-reactive lubricating composition on the workpiece outer surface, the outer surface having been alkaline cleaned, hot water rinsed, acid pickled, and cold water rinsed.
Abstract:
The invention includes a lubricating composition comprising a major amount of an oil of lubricating viscosity, and a minor amount of (A) a sulfite or sulfate overbased or borated overbased metal salt of an acidic organic compound, wherein the lubricating composition contains less than 1.5% by weight of the reaction product of a polyisobutene substituted succinic anhydride and a polyamine, and provided that when (A) is a sulfate overbased or borated overbased metal salt, then the lubricating composition includes (B) at least one phosphorous of boron antiwear/extreme pressure agent, or (C) a sulfur compound. The invention also includes grease and functional fluids containing the sulfite and sulfate overbased metal salts. These composition have improved antiwear, antiweld, and extreme pressure properties.
Abstract:
This invention relates to a composition comprising a major amount of an oil of lubricating viscosity, and (A) an organic ammonium thiosulfate. The lubricating composition is either free of added lead containing compounds or additionally contains (B) a phosphorus or boron antiwear/extreme pressure agent, or both. The invention also includes greases and aqueous fluids containing organic ammonium thiosulfates. These compositions have improved antiwear, antiweld, extreme pressure and/or friction properties.
Abstract:
A method for the start up of a concrete pump using a small amount of an aqueous suspension of polymers, amorphous silicone dioxide and water-reducer rather than a conventional cement slurry.

Abstract:
A cyclophosphazene fluid composition containing organometallic or inorganic metal salts as antioxidants the antioxidants for use therein, and a method therefor, are disclosed herein. Suitable organometallic salts are formed by reacting a metal hydroxide with benzoic acid, substituted benzoic acids, or substituted phenols. The preferred inorganic metal salts effective for this purpose include various metal borates. The metal salt antioxidants are effective for reducing oxidation in the cyclophosphazene fluid in amounts of less than about 1% by weight of the overall composition.
