Oxidation stability is one of the important properties of lubricating greases, which has an impact on their storage and use, especially for long-term use at high temperatures. After oxidation of lubricating grease, its structural framework and performance will undergo changes, which will have adverse consequences for its use and storage. Oxidation of lubricating grease can lead to the production of acidic substances, which corrode metals during the use of lubricating grease
The commonly used oxidation stability testing method is the oxygen bomb method, which is SH/T0325-92
Automatically perform pressure detection, data recording, oxidation time calculation on the tested oil sample, and automatically end the test. While displaying the test curves and results on the screen, they are also automatically saved, allowing the operator to print them as needed
Method Summary:
Place the sample in an oxygen bomb heated to 99 ℃ and filled with 758 kPa of oxygen for oxidation. Observe and record the pressure at specified time intervals. After a specified time period, the degree of oxidation of the lubricating grease is determined by the corresponding decrease in oxygen pressure.
