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.

PROBLEM TO BE SOLVED: To provide a refrigerator oil composition satisfying both sludge dispersibility and prevention of abrasion and seizure in a sliding part composed of aluminum and/or iron of a compressor for the refrigerator, and to provide the compressor and freezing equipment using the same. SOLUTION: The refrigerator oil composition comprises an imide compound in an amount of 0.01-5 mass% based on the total amount of the refrigerator oil composition in a base oil which is at least one kind selected from a mineral oil and a synthetic oil. The compressor and the freezing equipment are obtained by using the composition. COPYRIGHT: (C)2007,JPO&INPIT

Abstract:
A resin composition which exhibits good sealability while keeping creep deformation to a minimum when brought into sliding contact with a mating member at a high contact pressure of over 10 MPa, and which will not damage a mating member made from an aluminum alloy while sliding in contact with lubricating oil. The resin composition is a pressure-resistant, sliding tetrafluoroethylene resin composition containing 100 parts by volume of a modified tetrafluoroethylene resin in the form of a copolymer of tetrafluoroethylene and partially modified tetrafluoroethylene, 5-40 parts by volume of carbon fiber, and 2-30 parts by volume of calcium sulfate whiskers having a Mohs hardness of 4 or less, and having, at 100° C., a maximum deformation rate in 24 hours, of 15% or less. A seal device to be brought into slide contact with an aluminum metal is molded from such a pressure-resistant, sliding tetrafluoroethylene resin composition.
Abstract:
The present invention provides a refrigerator oil composition which satisfies both sludge dispersibility and prevention of wear and seizing of sliding parts made of aluminum and/or iron, and a compressor and a refrigeration apparatus using the refrigerator oil composition. The refrigerator oil composition is characterized by comprising a base oil which is at least one member selected from mineral oils and synthetic oils, and at least one polyamide compound having two or more amide groups in the molecule and being present in an amount of 0.01 to 5% by mass based on the total amount of the refrigerator oil composition.
