ABOUT INDUSTRIAL LUBRICANTS

Industrial lubricants are oils, greases, fluids and other compounds designed to reduce friction and wear while protecting against corrosion. Special characteristics of the lubricant may enhance thermal conduction or insulate against an electrical current. Industrial lubricants may offer sealing, this will protect against moisture, gasses and other contaminants. Industrial lubricants may also be used as mold releasing agents and as anti-loading additives on abrasive products. Industrial lubricants are manufactured in various forms, they include low viscosity oils, high viscosity greases, waxes, high temperature silicates and powders known as solid lubricants.

Industrial lubricants are made up of a base oil and contain additives that improve or enhance the lubricants performance, for example EP (extreme pressure) additives improves the load carrying capability of the lubricant by forming a film layer between surfaces to withstand high loads. Many other additives are added to lubricants to give them specific characteristics, more of these include anti corrosion additives, anti wear additives, detergents, anti foaming additives, viscosity modifiers and antioxidants to mention but a few. Greases and pastes are thick high viscosity products that do not flow or run off the surface where they are applied, like lubricating oils, greases also contain additives to give them certain desired characteristics such as resistance to high heat or loads. From the above we can gather that there are two broad categories of industrial lubricants namely lubricating oils and greases that include pastes and compounds. These industrial lubricants all contain additives that enhance their capabilities, making them suited for the demands of industrial applications and manufacturing processes.

Industrial lubricants differ as much in application as in composition, some lubricants have petroleum or mineral base oils, glycol or polyglycol, ester or diester or silicon bases. Some Industrial lubricants contain high water content fluids, natural oils, water-soluble fluid, waxes or soap complexes. Industrial lubricants that are based on halogenated hydrocarbons include chlorofluorcarbon (CFC), halogenated fluorocarbon (HFC), halogenated chlorofluorocarbon (HCFC), and perfluorocarbon (PFC). Fluoropolymer-based solid lubricants include polytetrafluoroethylene (PTFE) and are available in different forms. Synthetic fluids do not contain petroleum and mineral oil base, but give excellent fire resistance and cooling. The characteristics, cost and heat transfer performance of semi-synthetic fluids is between that of soluble oil fluids and synthetics.

Industrial lubricants have important properties that need to be considered when choosing a lubricant for a specific application. The kinetic viscosity, viscosity index, pour point and flash point being some of the most important considerations. Kinetic viscosity is the time required for a fixed amount of fluid to flow through a tube under the force of gravity only. The viscosity index describes the change in viscosity of a fluid at two temperatures namely 38.7°C and 98.9°C. Pour point of a fluid is the lowest temperature at which the fluid flows and flash point is the lowest temperature at which a fluid will form sufficient vapors to ignite in air near the surface of the fluid. Greases, pastes and compounds also have certain considerations for example, penetration and dropping point. When referring to the penetration of grease, we are referring to the consistency or hardness of grease. The Dropping Point of grease is that temperature at which grease passes from a semi-solid to a liquid state. It is crucial to know this temperature because in applications requiring a semi-solid grease, a grease that has gone too soft wont give adequate lubrication.
