Abstract:
Provided is a grease composition with a long service life under high-temperature conditions, considerable low-evaporability, and incombustibility. The invention provides a grease composition comprising, as a base oil, an ionic liquid formed of a cation and an anion and having an ion concentration of 1 mol/dm 3 or more as measured at 20°C, and a thickener having a dropping point of 260°C or higher.
Abstract:
The invention concerns a high temperature lubricant for lubricating two heated metal objects, in mutual contact through their surfaces, moving relative to each other, in particular steel objects, comprising at least 80 wt. % of an alkaline orthophosphate and having a melting point higher than the maximum working temperature of said heated metal objects. The inventive lubricant is mainly used for lubricating mandrel bars during production of seamless metal tubes.
Abstract:
Particles each of which consists of an inorganic polyvalent metal compound as a nucleus and a coating of a metallic soap of the polyvalent metal coating the nucleus (coated particles); products and preparation processes using the particles; a lubricating coating forming agent wherein particles each of which consists of a polyvalent metal salt of phosphoric acid as a nucleus and a coating of a metallic soap of the polyvalent metal coating the surface of the nucleus are suspended in an aqueous solution of a water soluble inorganic salt and/or a water soluble organic acid salt; and a lubricating coating. The coated particles are novel particles which can be used as an ingredient of coating-type lubricating coating; are excellent in seizure resistance; can inhibit wear of tools at the time of plastic working since the friction coefficient of the surface of the particles is low; and are slow to cause pollution of working oils. Lubricating coating obtained by applying the lubricating coating forming agent onto the surface of a metallic material gives excellent cold plastic working properties, namely lubricity and seizure resistance to the metallic material.

Abstract:
A process is disclosed for manufacturing a lubricant composition comprising combining a superabsorbent polymer with a material for decreasing friction between moving surfaces. The superabsorbent polymer absorbs from about 25 to greater than 100 times its weight in water and may comprise a polymer of acrylic acid, and acrylic ester, acrylonitrile or acrylamide, including co-polymers thereof or starch graft copolymers thereof or mixtures thereof. A product produced by the process includes the material for decreasing friction comprising a petroleum lubricant containing an additive, water containing an additive, synthetic lubricant, grease, solid lubricant or metal working lubricant, wherein the synthetic lubricant, grease, solid lubricant or metal working lubricant optionally contain an additive. A process comprising controlling the delivery of a lubricant to at least one of two moving surfaces in order to decrease friction between said moving surfaces, is also disclosed. This process includes applying the lubricant composition to at least one of the surfaces. The lubricant composition in this instance comprises a superabsorbant polymer combined with a material for decreasing friction between moving surfaces, wherein the material for decreasing friction comprises a petroleum lubricant, water, synthetic lubricant, grease, solid lubricant or metal working lubricant, and optionally an additive.
Abstract:
A method for treatment of bacterial infections with rifalazil administered once-weekly, or twice-weekly. A method for treatment of tuberculosis caused by Mycobacterium tuberculosis, infections caused by Mycobacterium avium complex, infections caused by Chlamydia pneumoniae and infections caused by Helicobacter pylori by administering to a patient suffering from the bacterial infection 1-100 mg of rifalazil once or twice a week. In this dose regimen, the treatment is fast, efficacious and eliminates undesirable secondary symptoms observed with daily doses of 1-50 mg of rifalazil.
Abstract:
A stainless steel wire is plated with nickel (Ni) to a thickness of from not less than 1 mu m to not more than 5 mu m. An inorganic salt coat film mainly composed of at least one of potassium sulfate and borax (borate) and free from fluorine (F) or chlorine (Cl) is then deposited on the nickel (Ni) plate 2 as the substrate. The steel wire is then drawn to a reduction of area of not less than 60% to adjust the surface roughness thereof to a range of from 0.80 to 12.5 mu mRz, preferably from 1.0 to 10.0 mu mRz.
Abstract:
Dry film lubricant coatings are provided by using a silicone resin binder, either as an aqueous emulsion or in a solvent-based system, to fix an alkaline earth metal fluoride to a substrate. The compositions used to apply the coatings may also include relatively minor amounts of xylene, ammonium benzoate, a wetting agent, and/or a porosity-inducing agent-although none of those additives remains in the cured coating. Multi-layer dry film lubricant coatings are also disclosed, with the multi-layer coating having a basecoat layer as described above, and a topcoat layer made of a layer-lattice solid such as graphite or molybdenum disulfide, and a silicone resin, aluminum phosphate or an alkali metal silicate binder.
