With the progress of human social civilization and the continuous improvement of people's needs for life, the voice of food safety is also getting higher and higher. Therefore, the application of food grade grease has been paid more and more attention. While many developed countries continue to raise the threshold of food import, they are also strengthening their own food safety management. Some developed countries have more and more standardized and strict requirements for the use of food-grade lubricants in the field of food production, which has caused great obstacles to the export of food in developing countries including my country. This will further promote the development and application of food-grade lubricants in my country.

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.

Liquid lubricants are the lubricants with the largest amount and variety, including mineral oils, synthetic oils, animal and vegetable oils, and water-based fluids. Among them, the amount of mineral oil is the largest, accounting for more than 90% of all liquid lubricants.

Electrical contactors can be used in power devices, such as relays, sliding wire rheostats and other mechanisms with poor precision. Dry contactors oxidize and vulcanize rapidly. The generation of millivolt arcs (sparks) between the contactors promotes the formation of nitrogen oxides, corrosives such as HNO3. The presence of suitable grease can reduce the contact resistance, prevent sparks when the contactor is de-energized, protect the contactor from corrosive agents (water, oxygen, nitrogen, etc.), and reduce the impact of the contactor when it is energized.

The spark plug is an important part to keep the car engine working. The gasoline engine generates power through the timely combustion of fuel and mixed gas, but the gasoline used as fuel is difficult to spontaneously ignite even in a high temperature environment. It is necessary to use it to make it burn in time. "Fire" to ignite. The role of the spark plug is revealed at this time. It uses a high-voltage discharge to create a high-energy arc that burns engine fuel. The quality of the spark from the spark plug determines the degree of combustion of gasoline in the engine, which in turn affects the performance of the engine.

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.
