Know About Lubricants
The most commonly used industrial lubricants are oils and greases. They help in reducing friction and wear. Their primary function is to make the solid surfaces function smoothly by forming an oily liquid film. They are also used to control temperature and eliminate harmful particles. The best lubricant reduces solid-to-solid friction and eases any amount of resistance that would obstruct movement and induce wear and tear.
Greases are produced by mixing mineral زيوت and lithium-based soaps. They also incorporate some fortifying components, such as molybdenum disulfide, graphite, and teflon. Greases provide the lubrication properties of oils together with stickiness, making them perfect for lubricating open surfaces and exposed moving parts. The additives added to grease prevent corrosion, rust, wear and tear. Mineral oil-based greases are formulated to provide excellent performance for several applications; Shield’s greases normally delivers substantial benefits, including prolonged tool life.
Here is how greases help
● Reduces friction and wear
● Decreases or eliminates corrosion
● Protects bearings from water and other contaminants
● Resist drip, soaking, and throw off
● Retains flexibility under extreme pressure conditions
● Withstands or repels dampness.
● Endures various temperatures
Typical applications: Machinery, bearings, chains, links
Types: Multipurpose grease, Extreme pressure grease, Complex greases.
Lube Oils are relatively viscous liquids composed of long polymer chains, with additives added to strengthen several other properties. Common types of additives include oxidation inhibitors to avoid oil degradation and a cleansing agent to prevent the formation of deposits. An oil’s flexibility at different temperatures is based on the viscosity index. The higher the viscosity index is the more flexible the oil is under wide a range of temperatures.
Typical applications: Auto engines, Industrial equipments and machineries.
Types: Motor oil, Industrial oils (Hydraulic, Turbine, Compressor), Gear oils, Mould oils
