Problems solved by technology

[0002] With the rapid development of modern industry, the requirements for lubricating materials are becoming increasingly stringent. For mechanical equipment that operates continuously under high load, high speed and high (low) temperature, the original lubricating grease can no longer meet the current needs; such as: sealed bearings usually require The service life of the grease is the same as the life of the bearing, and the grease is not replenished in the middle; there are also many high-temperature parts in the chemical industry and the printing and dyeing industry, which require transportation or equipment that is in contact with corrosive substances. During these processes, some acid gases are often released. On the one hand, it causes bearing corrosion, and on the other hand, it destroys the grease structure, which makes the grease thinner and lost quickly, resulting in poor lubrication. Therefore, high-quality and multi-effect grease is the direction of its development
