What are dispersants used for?

Dispersant is an important industrial additive, mainly used to prevent the agglomeration of granular substances, improve dispersion efficiency, and enhance the stability of dispersed substances. It is widely used in ceramics, metallurgy, cement, pesticides, fertilizers, dyes, coatings, plastics, rubber and other fields.

The main functions of dispersants are as follows:

Improve the dispersion efficiency of solid substances: After the solid substance is added with a dispersant, its surface tension can be quickly reduced, so that the solid substance can be quickly dispersed in the liquid, and its dissolution speed and solubility can be improved, thereby achieving the purpose of improving the dispersion efficiency.

Enhance system stability: Dispersants can form a protective film to prevent the agglomeration of particulate matter, enhance the stability of the system, and effectively improve product quality and performance.

Increase system fluidity: Dispersants can reduce the surface tension of liquids and make them more fluid, thus improving production efficiency and product quality.

Improve product appearance quality: Dispersants can evenly disperse solid substances in liquids, making the product appearance more delicate and smooth, and improving product appearance quality.

In summary, dispersants play an important role in industrial production and can improve production efficiency and product quality, reduce production costs, and create more economic benefits for enterprises.

So what is the purpose of dispersants used in lubricating oils?

Lubricating oil dispersants are used as additives in lubricating oils, such as engine oils and industrial lubricants, to prevent the build-up of sludge and deposits. These deposits form when insoluble particles such as carbon and dirt mix with lubricating oil and settle in the engine or mechanical components.

Lubricating oil dispersant is an important additive, mainly used to reduce friction and wear inside automobile engines, improve fuel efficiency, and extend engine life. This article will introduce in detail the function, classification, usage and precautions of lubricating oil dispersants.

The working principle of lubricating oil dispersants

Lubricating oil dispersant is a surfactant that mainly works through the following principles of action:

The main function of lubricating oil dispersants is to disperse and suspend these insoluble particles in the oil, preventing them from gathering and forming deposits. This helps maintain lubricant cleanliness and performance and promotes smooth operation of equipment or machinery.

The purpose of lubricant dispersants is to adhere to the surface of insoluble particles and form a protective barrier around them. This barrier prevents particles from clumping together and clumping, keeping them suspended throughout the system. As the lubricant circulates, dispersed particles are removed through filters or during oil changes, preventing them from settling in critical components.

By effectively dispersing insoluble particles, lubricant dispersants help:

1. Prevents sludge formation: Sludge is a sticky substance that can settle on engine components and reduce the efficiency and performance of the lubrication system. Dispersants help prevent sludge buildup by keeping insoluble particles dispersed and preventing them from settling.
2. Reduce deposit formation: Deposits can form on engine components such as pistons, valves and bearings and cause increased friction, wear and reduced engine performance. By dispersing insoluble particles, lubricant dispersants minimize the formation of these deposits, helping to keep your engine clean and extend its service life.
3. Maintain lubricant properties: Insoluble particles can interfere with the oil’s lubricating properties, reducing its ability to reduce friction and prevent wear. Dispersants help keep these particles dispersed and prevent them from interfering with the lubricant’s properties, allowing it to effectively lubricate and protect machinery.

Reduce harmful additives in oil: Lubricating oil may contain some harmful additives, such as wear particles and oxidation products. These substances can cause friction and wear inside the engine. Lubricant dispersants break these harmful additives into small particles, making them easier to remove from inside the engine.

Improve fuel efficiency: Lubricant dispersants can reduce friction and wear inside the engine, thereby reducing fuel consumption. Additionally, it improves fuel efficiency by reducing carbon deposits and cleaning piston rings.

Reduce engine wear: Lubricant dispersants can form a protective film that covers the friction surfaces inside the engine, thereby reducing engine wear. It also removes harmful additives from friction surfaces, thereby reducing wear.

Classification and characteristics of lubricating oil dispersants

Lubricating oil dispersants are mainly divided into the following three categories:

Organic dispersant: Organic dispersant has good dispersing properties and antioxidant properties. They can effectively reduce friction and wear inside the engine and extend engine life.

Inorganic dispersant: The main component of inorganic dispersant is minerals, which has high dispersion and high cleanliness. They clean carbon deposits and oxidation products from inside the engine and improve fuel efficiency.

Composite dispersant: Composite dispersant combines the advantages of organic dispersants and inorganic dispersants, and has wider applicability and higher performance.

Adding amount: The amount of lubricating oil dispersant added should be determined according to the vehicle model and type of lubricating oil. If the lubricating oil already contains other additives, the amount of dispersant added should be appropriately reduced.

Ensure good ventilation: Lubricant dispersants can produce gases as they decompose. Therefore, when adding lubricating oil dispersant, ensure good ventilation and avoid operating in a poorly ventilated environment.

Summary

Lubricating oil dispersant is an important additive that can effectively reduce friction and wear inside the engine, improve fuel efficiency, and extend engine life. When using lubricant dispersants, you should pay attention to adding the recommended amount, ensure good ventilation, and choose qualified products through regular channels. It is believed that with the continuous advancement of technology, lubricant dispersants will play an even more important role in future development.
