Grease will separate out oil during storage and use, a small amount of oil separation is normal, and excessive oil separation will directly lead to the destruction of the grease structure or even loss of use value. Proper storage and use techniques can effectively control oil separation.

The solubility of metal soaps of different fatty acids in mineral oil (non-polar liquid) is different, which has a great influence on the difficulty of making lubricating grease and the structural properties of the product. Fatty acid soaps with fewer carbon atoms have lower solubility in mineral oil, and are not easily dispersed in oil to form a stable system. The resulting grease is easy to separate oil and has low consistency. Fatty acid soaps with more carbon atoms have greater solubility in oil and greater dispersion in oil, making it easier to form a more stable dispersion system, resulting in less oil separation and greater consistency. However, if the fatty acid has too many carbon atoms, the solubility of its soap in the oil is too large to be easily crystallized to form a structure, and the resulting grease has a very small consistency, or even a fluid. Therefore, when making grease, it is generally best to use fatty acids with carbon atoms of 12-18.

On August 16, 2020, the fourth meeting of the third chairman committee of the Grease Professional Committee of China Petroleum and Chemical Industry Federation, which represents the most advanced industry meeting for domestic greases, was successfully held in Kunming, Spring City. As one of the thirteen chairman units in the country this year, Jiurun Lubricating Materials Co., Ltd. has made careful preparations for participating in this meeting. At the meeting, the current application and market prospects of special greases in emerging industries were discussed and exchanged with the participating scientific research institutions and application units, which will play a positive role in promoting the development and market application of domestic grease products in the future. .

During long-term storage, the physical and chemical properties of grease will change due to the influence of external temperature, humidity and the action of oxygen in the air. In addition, due to the mixing of mechanical impurities such as dust, sand cores, rust, and moisture, as well as contamination by microorganisms, its performance will also be reduced.

As a high-tech petroleum product, grease plays an important role in the rapid development of the national economy, cutting-edge science and technology and the development of the national defense industry. The research and development of new grease products and production processes is the most interesting.

The production process of lubricating grease can be basically divided into two categories - batch production process and continuous production process. Due to the wide variety of grease products and small batches, the batch method is mainly used for production, which is conducive to the flexible change of grease varieties and to meet the needs of different types of greases in different quantities. At present, most of the lubricating grease in the world is produced by batch production process, and the production of lubricating grease by continuous production process has only limited application. The production of lubricating grease in my country is also mostly produced by batch production process, although the production process of lubricating grease produced by tube furnace has a semi-continuous nature, which is rare in the production of lubricating grease in my country.

Viscosity is the speed at which lubricating oil flows at a certain temperature, and it changes with temperature. Generally, the viscosity at 40°C and 100°C is used as the standard for high temperature grease manufacturers. Viscosity is an index for the classification and grading of various lubricating oils, which is decisive for quality identification and determination.
