Abstract:
The invention relates to a novel emulsified composition comprising (a) major amount of an aqueous phase, (b) a minor amount of an organic phase and (c) a minor but effective amount of at least one emulsifier to emulsify the aqueous and organic phase resulting in a water in oil emulsified lubricants, in particular an emulsified greases. Further, the present invention provides a process for making the emulsified compositions.
Abstract:
The invention relates to a method of lubricating the bearings of solid fuel pulverizers, for example, coal pulverizers. The method involves supplying to the bearings a lubricating composition designed to have superior performance compared to conventional coal pulverizer bearing lubricants. The invention also provides a bearing lubricant for a coal pulverizer as well as its use in coal pulverizing equipment to improve the service life and/or durability of bearings in coal pulverizing equipment. The invention also provides an additive composition for use in a bearing lubricant for a coal pulverizer, as well as the use of the additive composition to improve the service life and/or performance of the bearing lubricant.
Abstract:
The invention provides a lubricating composition comprising an oil of lubricating viscosity and an amine-functionalised additive, wherein the amine-functionalised additive is derived from an amine having at least 3 aromatic groups, at least one -NH2 functional group, and at least 2 secondary or tertiary amino groups. The invention further provides for the additive to have improved thermal and oxidative stability modifying properties. The lubricating composition may include circulating oils, turbine oils, hydraulic fluids, transformer oils and greases as well as others that require good oxidation stability and good rust inhibition properties.
