Schmierölzusätze

Schmierölzusätze, often referred to as oil additives, are chemical compounds added to lubricating oils to enhance their performance properties or impart new characteristics. These additives are crucial for optimizing the function of engines, transmissions, hydraulic systems, and other mechanical components. They work by modifying the physical and chemical behavior of the base oil.

Common types of additives include detergents, which prevent the buildup of sludge and varnish; dispersants, which keep insoluble particles suspended in the oil; anti-wear agents, which form a protective layer on metal surfaces to reduce friction and wear; antioxidants, which slow down the oxidation of the oil, extending its service life; and viscosity index improvers, which help maintain a stable viscosity across a range of temperatures. Other additives may include pour point depressants, anti-foam agents, and corrosion inhibitors.

The formulation of a lubricant typically involves a carefully balanced combination of base oil and various additives, each selected to meet specific operational requirements and environmental conditions. The concentration and type of additives used depend on the intended application, such as automotive engines, industrial machinery, or marine engines. The effectiveness of these additives is vital for ensuring the longevity and efficiency of mechanical systems by reducing wear, preventing deposit formation, and improving overall lubrication.
