Category of Petroleum Product Additives

It is worth mentioning that petroleum product additive is not a panacea. It cannot turn inferior oil products into high-quality oil products. Additives are only one of the main factors to improve the quality of oil products. The contribution of petroleum product additives depends not only on their special components but also on the quality of basic oil.

Category of petroleum product additives

• Detergent refers to chemicals that can be cleaned and keep the engine components clean in fuel or lubricant. In the engine oil formula, most of the cleaning agents are acidic metal soap to neutralize or produce acids produced in oxidation or combustion.
• Dispersant allows solid pollutants to suspend chemicals in the oil in the oil, preventing substances such as mud, paint film, and silly on the engine parts.
• Antioxidant and corrosion inhibitors or oxidation-corrosion inhibitors can inhibit oil oxidation and protect the chemical erosion of oil or lubricating surfaces from water or other pollutants.
• Extreme pressure agent prevents sliding metal surface sintering and abrasion chemicals under extreme pressure conditions.
• Antiwear agents can generate a thin film on a higher load component to prevent chemicals from contacting metal and metal.
• Oiliness additive border lubrication conditions will enhance the lubrication and chemicals that prevent wear and abrading. The oil-based agent is usually a compound of the polar group at the end of the hydrocarbon chain. These compounds have a strong affinity for metal. The effect is to adsorb the friction surface through the polar group to form a molecular orientation adsorption film to prevent it from preventing the molecular orientation adsorption membrane to prevent it. Metal contact between each other, thereby reducing friction and wear.
• A friction modifier can reduce the chemicals of the friction coefficient between the metal surfaces of the two contacts. FM generally does not react with metal but is adsorbed on the metal surface. The adsorbing membrane can reduce the friction heat of the oil/metal interface and facilitate the improvement of efficiency under certain conditions. FM is usually a derivative containing phosphorus or nitrogen.
• The antioxidant can improve the antioxidant properties of oil products and chemicals that extend their use or storage life. An antioxidant is also called an oxidation inhibitor.
• Metal deactivator can make metal passivation and loses catalytic chemicals called oil metal reducing actors or metal passivation agents, also known as anti-catalyst additives. The automatic oxidation of hydrocarbons is a chain reaction based on the free radical medium. During the intermediate decomposition of the intermediate through the oxide into a free radical process, metal ions, especially copper ions, plays a strong catalytic effect.
• Rust preventive or antirust adds is a chemical that forms a thin film on the metal surface to prevent metal rust. In running and storage, it is difficult to contact the oxygen, humidity, or other corrosive media in the air. These substances will corrode electrochemical and rust on the metal surface. To prevent rust, the above substances must be prevented from contacting metal.
