Abstract:
An aqueous lubricant for use in plastic working of a metallic material which comprises (A) a water soluble inorganic salt and (B) a wax, wherein the components are dissolved or dispersed in water, and wherein a solid concentration ratio (weight ratio) (B)/(A) is 0. 3 SIMILAR 1.5. and a method for producing a lubricative film, characterized in that a lubricative film is produced by applying the aqueous lubricant, preferably in a dried weight of 0.5 SIMILAR 40g/m , on the surface of a metallic material, providing no chemical conversion layer thereon, followed by drying. The aqueous lubricant preferably further comprises (C) a metal salt of a fatty acid in a solid concentration ratio (C) /(A) of 0.01 SIMILAR 0.4. The water soluble inorganic salt (A) is preferably selected from among a sulfate, a silicate, a borate, a molybdate and a tungstate. The wax is preferably a synthetic wax which is dispersed in water and has a melting point of 70 SIMILAR 150 DEG C. The metal salt of a fatty acid (C) is preferably obtained through reacting a saturated fatty acid having 12 SIMILAR 26 carbon atoms with a metal selected from among zinc, calcium, barium, aluminium, magnesium and lithium. The aqueous lubricant can be used for imparting excellent lubricity with ease to the surface of metal having no chemical conversion layer formed thereon.

Abstract:
A process for drawing wire employing a lubricant comprising perfluorocarbon compounds (PFCs), including aliphatic perfluorocarbon compounds ( alpha -PFCs) having the general formula CnF2n+2, perfluoromorpholines having the general formula CnF2n+1ON, perfluoroamines (PFAs) and highly fluorinated amines (HFAs), and perfluoroethers (PFEs). Such fully and highly fluorinated carbon compounds exhibit a very high degree of thermal and chemical stability due to the strength of the carbon-fluorine bond. Further, because the compounds are fully fluorinated, and therefore do not contain chlorine and bromine, they have zero ozone depletion potential (ODP). Further, because the compounds are photochemically non-reactive in the atmosphere, they are not precursors to photochemical smog and are exempt from the United States Environmental Protection Agency (EPA) volatile organic compound (VOC) definition. Further, because they are volatile, the compounds are easily removed at the end of the process without need for an additional cleaning step. The process provides wire at significantly higher production speeds and longer die life with improved quality and less byproduct debris.
Abstract:
Disclosed is a lubricating oil which has a low viscosity and a low vapor pressure at the same time, is free from a risk of inflammation and excellent in heat resistance. The lubricating oil has friction characteristics equivalent to those of the conventional hydrocarbon lubricating oils, and can be used for a long time under extremely severe conditions such as at high temperatures in vacuum condition. The lubricating oil contains, as a base oil, an ionic liquid which is composed of cations and anions and has an ion concentration of not less than 1 mol/dm3.
Abstract:
The invention provides a lube oil which exhibits low vapor pressure despite having low viscosity, is non-flammable, exhibits excellent heat resistance, has tribological characteristics equivalent to those of conventional hydrocarbon-based lube oils, and can be used for a long time under very severe conditions such as high temperature and vacuum. The lube oil contains, 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.
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.
