Rolling with the oil or grease often have additives added. According to different needs, different varieties of additives, generally have the following categories:
1, anti-corrosion additives
Add the oil or fat in it at the metal surface to form a protective layer to prevent corrosion.
At present, the introduction of a new anti-rust agent - VCI agents (also known as volatile corrosion inhibitor) which has a volatile at room temperature, the gas distribution around the metal around the surface of the metal layer of protective film.
2, anti-oxidants
Oil during use, due to oxidation to generate glial and low molecular weight organic acids and other oxidation products, the quality deterioration, the use of antioxidants can slow the oxidation process.
3, quiet dispersant
Easily in high temperature oxidation of the oil resin and asphaltene product of the friction surface of film or coke. Oil dispersants can quiet water, acids, sediments, suspended in oil to prevent them deposited on the surface. Mainly used for internal combustion engine lubricating oil.
4, oil additives and extreme pressure additives
Under normal conditions, the use of oil additives, lubricant film can enhance the ability to improve lubricity.
In the high-pressure, high temperature used under harsh conditions of extreme pressure additives, it can under such conditions with the metal surface to form a solid compound film, lubrication, protection.
The use of a specialized additive technology, should be conducted under the guidance of professionals.
