Abstract:
A lubricating oil for refrigerating machines which comprises an oxygenic compound as a base oil and which, when incorporated into a chlorine-free C1 refrigerant in an amount in the range of 3 to 50 wt.% based on the sum of these, is compatible therewith in any of the concentrations at a temperature of -10 DEG C or lower; and a hydraulic composition for refrigerating machines which comprises (A) a chlorine-free C1 refrigerant and (B) the lubricating oil. In the composition, the oil has excellent compatibility with the chlorine-free C1 solvent, especially difluoromethane. The composition is excellent in antiwearing properties, lubricating properties, stability, etc.
Abstract:
A water based dispersion that includes lubricating nanoparticles. The lubricating nanoparticles can be provided by at least one intercalation nanoparticle of a metal chalcogenide in dispersion with the water base. The at least one intercalation nanoparticle may have a geometry that is fullerene-like, tubular-like structure or be substantially spherical or the intercalation nanoparticles may include particles have each of the aforementioned geometries. The intercalation nanoparticle is surface treated with a dispersant that is water soluble and includes a polar functional group.
