The present invention relates to compositions and processes of using perfluoropolyether to maintain or improve the oil return, lubrication, cooling capacity, or energy efficiency of a refrigeration, air conditioning or heat transfer system.
摘要:
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.

摘要:
A process for coating a machine part surface wherein the surface is cleaned, abraded and treated so as to render the surface directly bondable to a resin-bonded lubricant coating. A resin-bonded lubricant coating then is directly applied to the treated machine part surface and cured so as to cross-link the resin.
摘要:
Novel lubricant mixtures are disclosed having unexpectedly high viscosity indices. The mixtures are blends of high viscosity index polyalphaolefins prepared with activated chromium on silica catalyst and polyalphaolefins prepared with BF3, aluminum chloride, or Ziegler-type catayst. Superior blends are also prepared from HVIXPAO with mineral oil and/or other synthetic liquid lubricants.
摘要:
Improved composite bearings are provided employing cold forming and sintering techniques. Improvements in compositions for impregnating porous layers of composite bearings are provided comprising lead or lead alloy, perfluorinated polymer, particulate thermoplastic polymer and clay in particular proportions. When such materials are formed into bearings and subsequently sintered, improved resistance to stripping and wear is provided.
摘要:
A part is made of a material comprising less than 90% by weight of a polymer selected from the group consisting of polytetrafluoroethylene, polyurethane, nitrile, fluoroelastomer, and polyphenylene sulfide; and more than 10% by weight of another material, comprising about 15% to 60% by volume of grains of titanium carbide dispersed through a metal matrix.
摘要:
The present disclosure provides for mixtures, methods for making mixtures, articles, methods for making articles, and methods of using articles. In an aspect, the articles have superior tribological properties owing to combinations of polytetrafluoroethylene and an irradiated fluoropolymer described herein.
