All relative motion of two object surfaces exists between the phenomenon of friction, resulting in wear, so the need for lubrication. The purpose of lubrication is to reduce friction resistance, reduce surface wear, prevent corrosion, prolong service life, ensure the normal operation of equipment. Friction and lubrication is an interdisciplinary science involving physics, chemistry, materials, mechanical engineering and surface engineering. The efficient operation of mechanical equipment is closely related to lubrication. The efficient use of energy and environmental protection are directly related to lubricants and lubrication technology, which has become a functional element of engineering technology. Today, as a global manufacturing center, China's high-quality lubricants and scientific system lubrication technology will play an increasingly important role.

Lubrication is so important, in contrast, many industrial and mining manufacturing enterprises and mechanical equipment management or user neglect lubrication, do not understand lubrication, resulting in equipment wear, failure, damage, shutdown, production shutdown, energy waste and environmental pollution accidents occur from time to time, resulting in great economic losses. Among the types of lubricants, lubricating oil and grease are the most common. Grease is a solid to semi-fluid product prepared by dispersing thickener in liquid lubricant, adding appropriate additives to improve the application performance of grease and meet the use of harsh conditions. The use of grease or lubricating oil is used to reduce the friction and wear between two relatively moving surfaces. But under some conditions, grease lubrication must be used. For example, when the same size of rolling bearings run at the same speed, the energy consumption of grease is much lower than that of oil bath lubrication, which is more energy saving. Grease also has a wide range of temperature, easy to maintain on the surface of the machine, not easy to lose and leak, lubrication system and seal structure simplification, can effectively seal the pollutants and dust, good rust resistance and good thermal oxidation stability. But the application of grease is also limited by the equipment conditions, such as equipment bearing dn>350000, it is not suitable to choose grease lubrication, should choose lubricating oil or solid lubricating film lubrication.

In all kinds of grease products, composite lithium base grease, composite aluminum base grease, composite calcium sulfonate base grease, composite calcium base grease, composite titanium base grease, polyurea base grease and pengrun soil base grease is high drop point, high quality grease products, with excellent performance and long service life. The proportion of high drop point grease and lithium grease in grease output is an important indicator to measure the level of grease industry and grease application level of an enterprise or even a country. If we think about the future development direction of grease from the technical development trend of global manufacturing industry. Grease products and technological innovation must follow the low carbon economic development mode, that is, green, long life, environmental protection, energy saving, efficient and highly effective sustainable development mode.
