摘要:
Disclosed is a refrigerating machine oil composition, comprising a base oil and a metal salt of a carboxylic aid having from 3 to 60 carbon atoms. The refrigerating machine oil (lubricating oil) of the present invention is very well miscible with hydrogen-containing Flon refrigerants such as Flon 134a, achieves an excellent lubrication performance and is good enough to bring forth marked improvement of a wear resistance, particularly a wear resistance of aluminum-steel friction surfaces.

摘要:
A process for treating an aluminium can, comprising the steps of cleaning with an aqueous acidic or alkaline solution, drying and subsequently conveying the cleaned and dried can via automatic conveying equipment to a location where it is lacquered or decorated by printing or both. At least one exterior surface of the can, prior to the last drying of the surface before automatic conveying, is contacted with a lubricant and surface conditioner forming composition comprising ethoxylated, hydrogenated castor oil triglycerides, and the can is then dried without subsequent rinsing, thereby forming a film on the can to provide the surface of the can after drying with a reduced coefficient of static friction compared to an otherwise identical sequence of treatments where the lubricant and surface conditioner forming composition is substituted with water.

摘要:
Certain boron-containing, heterocyclic compounds are disclosed which impart extreme pressure, anti-wear and friction reducing properties to lubricating oils. Such lubricating oils are further provided with a hydrocarbon polysulfide derivative of 2, 5-dimercapto -1, 3, 4-thiodiazole as a copper corrosion inhibitor, or terephtalic acid as a lead corrosion inhibitor, or either an alkylated diphenyl amine, a bis (dithio-benzil) metal derivative, a sulfur bridged, bis hindered phenol or an alkyl or dialkyl diphenylamine as an oxidation inhibitor or a mixture thereof.
