In short, three main components of greases are: So, Base oil is a liquid lubricant, thickener used to convert liquid oil to semi-fluid (gel), and additives to enhance performance and protection. [6] Grease, as we know it today, is a three dimensional network of thickener particles. These thickeners can be broken into three groups: Simple - A simple soap resulting from the reaction of a single acid, usually 12 HSA and a metallic hydroxide, usually lithium, aluminum, calcium or sodium. Don't missour next Lubeletter where the variousnon-soap thickenersused to formulate Nye's greases will be featured. Additives are required to improve performance or to meet current standards and specifications. In addition, since their formulation is not based on metal soap thickeners like lithium greases, which can leave behind wetter sediment when used up, they typically are the preferred choice of lubrication for electric motors. Grease is one of the oldest lubricants used by humans dating back to 1400BC.[3]. Features and benefits. Soap thickeners not only provide thickening agent, usually soap in a liquid lubricant and rigidity to grease and they also affect desired properties may also contain additives that upgrade. And, while complex calcium soap based thickeners could withstand higher operating temperatures of up to 260 degrees Celsius, the arrival of higher performing lithium-based thickeners in the mid-20th century made these less advanced greases outdated. Lithium greases prepared from them have good lubricity, shear stability, thermal resistance (as measured by the dropping point, typically between 190-220C), and relatively low oil separation. The product consists of mineral or synthetic oil and hardened castor oil fatty acids called lithium stearate or lithium salt. U.S. Patent 2,417,428 was granted to Lester W. McClennan on March 18, 1947. A Nye formulation engineers understand the complex range of characteristics associated with grease thickeners and carefully formulate the proper thickener for your applications.
