Compared with ordinary lubricating oils, high temperature lubricating oils have a significant difference in coping with high temperature environment.
First, high temperature lubricating oils have a higher melting point. In a high temperature environment, ordinary lubricating oils are often prone to melting, resulting in a decline in lubrication effect. By adding special additives or improved grease formula, the high temperature lubricating oil can still maintain a stable melting point at high temperature, so as to ensure the lasting stability of the lubrication effect.
Secondly, high temperature lubricating oils have better antioxidant properties. Under high temperature environment, ordinary lubricating oils are easily affected by oxides, resulting in deposits and acidifiers, thus reducing the lubrication effect. By adding antioxidants, the high-temperature lubricating oil can effectively inhibit the occurrence of oxidation reaction, reduce the generation of sediment, and extend the service life of lubricating oil.
In addition, high temperature lubricating oils have lower volatility. Ordinary lubricating grease is easy to volatilize at high temperature, which leads to the reduction of lubrication effect. The high temperature lubricating oil uses special base oil and additives, which can reduce the volatility and ensure the stability of the lubrication effect in high temperature environment.
In addition, high temperature lubricating grease also has better corrosion resistance. In high temperature environment, ordinary lubricating grease is easy to be corroded by corrosive media, thus reducing the lubrication effect. The high-temperature lubricating grease can effectively prevent the corrosion of the corrosive medium to the lubricating grease by adding anti-corrosion agent, and maintain the stability of the lubrication effect.
Finally, the high temperature lubricating grease also has better sealing performance. In high temperature environment, ordinary lubricating grease is easy to melt and lose, resulting in reduced lubrication effect. The high-temperature lubricating oil through the special formula, can maintain a high viscosity, the formation of an effective sealing layer, so as to prevent the loss of lubricating oil, improve the durability of the lubrication effect.
In summary, compared with ordinary lubricating oils, high-temperature lubricating oils have higher melting point, better oxidation resistance, lower volatility, better corrosion resistance and better sealing performance under high temperature environment. These characteristics make the high temperature lubricating grease can maintain a stable lubrication effect under high temperature conditions, improve the operating efficiency and life of the machine equipment.（2024-05-28）
