What are the additives of lubricating oil?

What are the additives of lubricating oil?

Additives in lubricating oils

• Friction modifiers.
• Anti-wear additives.
• Extreme pressure (EP) additives.
• Rust and corrosion inhibitors.
• Anti-oxidants.
• Detergents.
• Dispersants.
• Pour point depressants.

What are lubricant additives made of?

Typical additives are organic amines and phenols. Metal deactivators create a film on metal surfaces to prevent the metal from causing the oil to be oxidized. Bases may be used to combat chemical decomposition of the base stock oil in the presence of acids.

What are the 6 different oil additives?

Types of Oil Additives

• Antioxidants. Oxidation causes engine parts to deteriorate when exposed to oxygen.
• Detergents. The objective of detergent oil additives is to get rid of impurities accumulating in the engine components.
• Viscosity Modifiers.
• Friction Modifiers.
• Anti-Foaming Agents.
• Lucas.
• Liqui Moly.
• Sea Foam.

What are the 5 types of lubricants?

What Are The Different Types Of Lubricants And Their Uses?

• Greases. Greases are composed by utilizing oil (typically mineral oil) and combining it with thickeners (such as lithium-based soaps).
• Oils. These thin liquids are composed of long polymer chains with some extra additives.
• Penetrating Lubricants.
• Dry Lubricants.

Why additives are added to lubricants?

The primary function of Lubricant additives is to improve the properties of the base stock under different operating conditions and the high performance requirements of any machinery. Lubricant additives are chemical components that need to blend well with the base oil to function as a single fluid.

Which are the two most common additives used in general purpose oils?

These primarily include enhancing the existing desirable properties, suppressing the existing undesirable properties, and imparting new properties. The most common additives are oxidation and rust inhibitors, extreme pressure, antiwear, and friction-reducing agents.

Why additives are used in lubricants?

What are the 3 types of lubricants?

There are three different types of lubrication: boundary, mixed and full film. Each type is different, but they all rely on a lubricant and the additives within the oils to protect against wear.

What are the four types of lubricants?

Lubricants are classified into four types: oil, grease, penetrating lubricants, and dry lubricants. The two most common lubricants you’ll encounter on a daily basis are oil and grease, but your facility will still use dry and penetrating lubricants.

What are detergent additives?

Detergent additives are important chemicals in the prevention of deposits being formed in engine combustion systems. Dirty combustion systems lead to loss of horsepower, poor fuel economy, poor idling and increased emissions. MCC has an extensive line of detergent additives for both gasoline and diesel-powered engines.

What is the lubricating oil?

Lubricating oil is a class of refined products used to reduce friction and wear between bearing metallic surfaces. It is distinguished from other fractions of crude oil by its high (>340°C) boiling-point region.

How are lubricants classified?

Lubricants are classified in several ways; these could be liquid, semisolid (greases), and solids such as graphite, molybdenum disulfide, boron nitride, tungsten disulfide, and polytetrafluoroethylene.
