Phosphate ester has excellent flame resistance and good lubricity, its oxidation stability is better than that of mineral oil, and its thermal stability is better at medium and low temperature, but it will decompose at high temperature. Phosphate esters decompose in contact with water. It is easy to act on rubber, plastics, coatings and paints. Phosphate esters of certain structures also have certain toxicity, which are issues that should be paid attention to when using phosphate esters.

Damping grease is a type of grease that plays a dual role of damping and lubrication between two friction surfaces. Damping grease is used in potentiometers, resistors, inductors, slow-opening mechanisms of tape recorders, and certain instruments and optical instruments in electronic components.

This is a widely used class of additives. Commonly used additives are divided into compounds containing S, P, Cl and other elements according to their composition; inorganic and organic solid lubricants such as various heavy metal chalcogenides; various metal fillers, etc. According to its mechanism of action, it can be divided into reactive type and layered crystal lubricating type. The reactive type also includes two types of additives that react with the metal surface to form a protective film and that the additive decomposes itself to form a protective film. Generally, reactive additives should be added after the grease is cooled, so as to avoid the decomposition and failure of the additives at high temperature, and also reduce the influence of the additives on the structure and properties of the grease. Most of the fillers are layered solid lubricants, such as graphite, MoS2, etc.

1. Calcium-based grease:Good water resistance, but poor heat resistance, the maximum use temperature: 60 ℃. Price: low.2. Sodium-based grease:Water resistance is extremely poor, heat resistance and rust resistance are average, generally used at about 80 °C, and the price is low.3. Aluminum base grease:Good rust resistance, poor heat resistance and water resistance, maximum use temperatur...

1. Anti-rust performance of grease Anti-rust performance is used to evaluate the protection of grease to bearings in the presence of water or water vapor. Important for greases used in wet environments. The commonly used method is GB/T5218 bearing static anti-rust test: put the grease into the bearing, put the bearing in an oven at 52 ° C and a relative humidity of 100%, and observe wheth...

Industry insiders recently said that the impact of the new crown pneumonia epidemic on the global lubricant market demand is almost the same as that of the 2008 global financial crisis. However, it is too early to predict the final impact, as it depends on how long the outbreak will be contained and the economic recovery will last.
