To make lubricants adhere better to metal surfaces, friction modifiers are often used. Friction modifiers are additives that reduce friction between moving parts and help lubricants adhere better to metal surfaces. They often contain molecules with polar or polarizable groups, which allow them to bond with metal surfaces to create a smoother, more protective surface. This reduces friction and improves the lubricant’s ability to adhere and stay in place, ensuring optimal lubrication and protection of metal surfaces.
Lubricants are indispensable in manufacturing and daily life. They play a key role in machinery operation, equipment maintenance, process production and many other aspects. In order to improve the performance of lubricants, it is often necessary to add some additives. This article will explore which types of additives help lubricants adhere better to metal surfaces.
Additives are substances added to improve the properties of a base material. Among lubricants and adhesives, the main function of additives is to enhance their adhesion ability, improve lubrication effect, prevent wear, control corrosion, etc. Common additive types include:
Petroleum additives: The main component of this type of additive is mineral oil, which has good lubrication and cleaning effects. However, petroleum additives tend to decompose under high temperatures and pressures, so their use environments are limited.
Polymer additives: These additives have high viscosity and form a tough protective film on metal surfaces. They also have good resistance to high temperatures and high pressures. However, polymer additives are more expensive to produce.
The main functions of additives in lubricants are as follows:
Reduce friction: Additives can effectively reduce friction between metal surfaces and reduce energy loss.
Prevent wear and tear: Additives can form a protective film on the metal surface to avoid direct contact with the metal surface, thereby reducing wear.
Control corrosion: Some additives have anti-corrosion properties, which can prevent metal surfaces from being oxidized and extend the service life of equipment.
To sum up, in order to help the lubricant adhere better to the metal surface, polymer additives can be selected. Because they have the advantages of high viscosity, forming a tough protective film, and resistance to high temperatures and pressures. In addition, polymer additives help reduce friction, prevent wear and control corrosion. In the development and production process of lubricants and adhesives, the advantages and disadvantages of various additives can be comprehensively considered according to actual application scenarios and needs, and the most appropriate additive type can be selected.
