High temperature grease has nine unique physical and chemical properties

In addition to general physical and chemical properties of grease, each grease should also have unique physical and chemical properties that show its application characteristics. The more quality standard is high, or the oil with strong special application, its unique physical and chemical properties are more prominent. The following single on the oxidation stability of high temperature grease to carry out the expression: oxidation stability, indicating that the aging resistance of grease, some industrial production grease with a long service life are provided with the technical indicators, so it becomes a unique performance of this type of oil provisions. There are many ways to measure the oxidation stability of oil, usually all a certain amount of oil in the presence of gas (or O2) and metal sulfide, oxidation at a certain temperature for a certain time, and then measure the acid value of oil, viscosity change and precipitation into the state. All grease is not the same as its organic chemical composition and the external situation, and have different automatic oxidation trend. With the process of application and oxidation effect, so slowly converted into some aldehydes, ketones, alkali and collagen fiber, leachate and other chemical substances, oxidation stability is to control the above adverse oil application of chemical substances into the performance.

High temperature grease has nine unique physical and chemical properties, they are:

1, oxidation stability.

2. Stability of hydrolysis reaction.

3. Anti-demulsification.

4. Thermal stability.

5. Foam resistance.

6. Value of gas release.

7, sealing gasket.

8, oil solubility and extreme pressure.

9. Erosion and rust.
