Grease plays an important role in lubrication, anti-corrosion, sealing and protection in mechanical equipment, and mechanical equipment is usually used under various environmental conditions, including high temperature, high humidity, humidity, corrosion and other conditions. Therefore, the durability and stability of grease is very important, which is the key to ensure the normal operation of mechanical equipment and prolong the service life.
Damp heat resistance test is a method to test the durability and stability of grease, which can simulate the use of grease in high temperature, high humidity or humid environment. In this kind of test, the grease is usually placed in a high-temperature, high-humidity or humid environment, and after a certain period of time, its oil film performance, flow performance, anti-oxidation performance, anti-rust performance and other indicators are tested.
Through the heat and humidity test, you can evaluate the use of grease in harsh environments, understand the problems and challenges it may face, determine the use conditions and scope of application of grease, and determine the required additives, base oils and manufacturing processes, etc. requirements. In addition, the humidity and heat resistance test can also help manufacturers improve and optimize the grease formulation and manufacturing process, improve the performance and service life of the grease, and provide customers with more reliable, high-quality and high-performance grease products.
The constant temperature and humidity Test Chamber can be used for the heat and humidity resistance test of lubricating grease. The performance of lubricating grease is greatly affected by environmental conditions, and the performance of lubricating grease is prone to change under hot and humid conditions, so it is necessary to conduct a damp and hot resistance test to evaluate its performance.
experiment method
Here's how to test it:
Test sample: Take a certain number of grease samples, label the samples as required and record the sample number, production date and other information.
Test conditions : set the test temperature and relative humidity in the damp heat Test Chamber and keep them stable. In general, the test temperature is 60°C and the relative humidity is 95%.
Test time : set the test time according to the needs, generally 72 hours.
experiment procedure:
1. Place the test sample in the damp heat Test Chamber, close the door of the Test Chamber and start the Test Chamber to set the test conditions.
2. After the test, take out the test sample and record the test result. Whether the performance meets the requirements can be evaluated by observing the appearance of the sample, measuring the changes in its physical properties (such as viscosity, dropping point, etc.) and chemical properties (such as acid value, base value, etc.).
Beichao reminds you: During the test, you should pay attention to the cleaning and ventilation inside the test box, so as not to interfere with the test results. At the same time, in the process of processing and evaluating the test samples, the operation should be strictly in accordance with the test requirements, so as to ensure the accuracy and reliability of the test results.
