Lubricant Additive Improve And Improve Aug 14, 2017

Because the base oil alone does not meet the performance requirements of the engine oil, the base oil is a refined ingredient extracted from the oil, with the most basic viscosity characteristics, and the additive is a chemical substance used to improve and improve the quality of the oil. Now we know that the oil is composed of base oil and additives in two parts. The base oil may be mineral oil or synthetic oil. The so-called mineral oil, that is directly from the oil refining for the production of lubricants. The synthetic oil is the use of crude oil or coal in the lighter ethane,Lubricant Additive propane and other cracked into ethylene, and then by complex chemical changes will be reorganized from the material, physical and chemical properties of stable, non-impurities, than mineral oil has many natural The advantages. When preparing additives, you can not one-sided emphasis on individual performance. In fact, high-quality lubricants show a comprehensive performance.

Lubricants are often used in the industry of oil, many people know that lubricants do not know the various additives in the lubricants, the following small series for everyone under the details.

1: Detergent Detergents

By chemical reaction or adsorption on the precursor of the precipitate, neutralizing and maintaining its dissolved state in the oil.

Such as: various sulfonates, phenates, salicylates, barium sulfonate, calcium sulfonate, BA-50 and so on.

2: Dispersants Dispersants

With the adsorption of polar groups and sludge and soot to prevent its aggregation, to keep dispersed in the oil.

Such as: a variety of succinimide, succinate, Mannich base and so on.

Antioxidants Antioxidants

Interrupting the free reaction of the oxidation reaction at the beginning of the oxidation reaction or decomposing the peroxide, terminating the free radical reaction, thereby delaying the oxidation of the lubricating oil.

Such as: ZDDP, shielded phenol, sulfide alkyl phenol,Lubricant Additive aromatic amine, organic acid copper salt, Elco 108 and so on.

4: Metal deactivators

In the metal surface and metal ions complex formation of passivation film, in order to reduce the metal on the oxidation of oil catalytic role.

Such as: nitrogen and sulfur-containing organic amines, sulfides, phosphite salts and other chelating agent.

5: Anticorros and Antirust Anticorros and Antirust

Is a polar compound, the metal has a strong adsorption force, can be in the metal and oil interface to form a close adsorption film to protect the moisture, moisture and acidic substances erosion; rust inhibitor can prevent oxidation, to prevent acid oxidation The formation of things, which play the role of rust. Can prevent non-ferrous metal surface corrosion and iron metal surface corrosion.

Such as: ZDDP, basic metal sulfonates, fatty acids and amines, boric acid amines, carboxylic acid amines.

6: Friction modifiers agents

Also known as oily agent, are active molecules with polar molecules, the preferred adsorption on the metal surface, the formation of a strong adsorption film, close to the boundary lubrication conditions,Lubricant Additive to prevent the metal friction surface and reduce friction.

Such as: organic fatty acids, amines, thiophosphates, sulfide olefins, animal and vegetable oils, phosphate, sulfurized lard and so on.

7: extreme pressure additives Extreme pressure additives

In a very high load or impact load through the chemical reaction in the metal surface with a low shear strength of the solid film, to prevent intermetallic surface abrasion or welding.

Such as: ZDDP, phosphite, sulfurized olefin, sulfurized fatty acid, borate, containing S, P, N compounds, phosphate and so on.

8: Antiwear Additive

In the light or medium load can be formed in the metal surface adsorption film, deposited film or reaction film, to reduce the metal surface wear material.

9: Viscosity index improvers Viscosity index improvers

Also known as thickener, with the polymer coil structure with the temperature rise and fall and stretch, to compensate for the base oil viscosity at high temperatures.

Such as ethylene / propylene copolymers, polymethacrylates,Lubricant Additive hydrogenated styrene / diene copolymers, mixed copolymers, and the like.

10: Pour point depressants

Improve the shape and quantity of wax crystals, inhibit the formation of crystal network, to maintain oil flow.

Such as polymethacrylates, polyalkene olefins, vinyl oxalate / fumarate copolymers, alkylnaphthalenes and the like.

11: Antifoam agents

Reduce the surface tension, so that bubbles can quickly overflow the oil, loss of stability and easy to break, thereby shortening the existence of the bubble time to prevent the formation of persistent foam oil.

12: Anti-emulsifier Demulsifying additive

Anti-emulsifier can change the oil and water interface tension, can eliminate the protective film outside the droplets, so that droplets easily combined together,Lubricant Additive in addition to anti-emulsifier can make a stable water-in-oil emulsion into unstable oil Type emulsion body, so as to achieve the purpose of water.
