Abstract:
Aqueous compositions, useful per se as lubricants or for forming dry lubricating films, comprising a finely divided solid lubricant suspended in an aqueous solution of an alkali metal silicate and an alkali metal lignosulfonate. Methods for making such compositions and for coating metal fasteners therewith. Metal fasteners lubricated with such compositions.
Abstract:
A composition and method for reducing the coefficient of friction and required pulling force of a wire or cable are provided. A composition of aqueous emulsion is provided that is environmentally friendly, halogen free and solvent free. The composition is compatible with various types of insulating materials and may be applied after the wire or cable is cooled and also by spraying or submerging the wire or cable in a bath. The composition contains lubricating agents that provide lower coefficient of friction for wire or cable installation and continuous wire or cable surface lubrication thereafter.
Abstract:
A refractory formulation containing an anhydrous solvent, an oleophilic rheology modifier and a refractory aggregate exhibits non-thermoplastic behavior, and remains plastic and formable at temperatures in the range of 10 degrees Celsius to 180 degrees Celsius. The oleophilic rheology modifier may effectively bind with the solvent to create a gel-like structure with organic solvents with moderate to high polarity. A phyllosilicate clay that has been treated with a quaternary fatty acid amine may be used as the oleophilic rheology modifier.
Abstract:
The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricant composition comprising a water-miscible silicone material having a silicone emulsion wherein the silicone emulsion contains less than 500 ppm of a triethanolamine salts of alkyl benzene sulfonic acid compounds.

Abstract:
The invention relates to the use of a super-slippery thin-layer film or coating for enhancing the lubrication capacity of a part to be subjected to great friction and wear. The film of the invention for improving the lubrication capacity of parts to be subjected to important friction and wear includes at least: a layer (3) of a hard material selected from titanium nitride (TiN), chromium nitride (CrN), titanium carbide (TiC), chromium carbide (CrC), tungsten carbide (W2C) and tungsten carbide-carbon composites (WC/C), alumina (AI2O3), molybdenum sulphide (MoS2), and materials of the hydrogenated amorphous carbon type (a: CH), the layer including on one surface thereof a series of dips and protrusions; and a layer (4) of an oleophilic material. The invention can particularly be used in the field of mechanics.
Abstract:
Cutting fluids for brittle materials, e.g., silicon ingot, comprise, in weight percent: A. 70-99% polyalkylene glycol (PAG), e.g., polyethylene glycol; B. 0.01-10% PAG-grafted polycarboxylate; and C. 0-30% water. These cutting fluids are used with abrasive materials, e.g., silicon carbide (SiC), to form cutting slurries. The slurry is sprayed on the cutting tool, e.g., a wire saw, to cut a brittle work piece, e.g., a silicon ingot.
