Protective oil is a kind of coating, which is mainly used to protect the surface of metal products, mechanical equipment, etc., from corrosion and oxidation. In use, protective oil usually needs to withstand the influence of harsh environments such as humidity and high temperature, so it is necessary to conduct a heat and humidity resistance test to evaluate its durability and reliability in such an environment. Specifically, the heat and humidity resistance test can simulate high-temperature, high-humidity climate conditions to detect changes in the physical, chemical, and electrical properties of protective oils in such environments, such as color, hardness, viscosity, and corrosion resistance. sex etc. Through the test, the durability and reliability of the protective oil can be evaluated, and reliable data support can be provided for its application.
The constant temperature and humidity Test Chamber is also widely used in the heat and humidity resistance test of protective oil. This test is to evaluate the damp heat stability of the protective oil by putting the protective oil sample in the damp heat Test Chamber, controlling the ambient temperature and humidity, and testing the performance of the oil sample under high temperature and high humidity conditions.
experiment method
The general test method is as follows:
Prepare samples: Collect the protective oil samples to be tested to ensure that the samples meet the standard requirements.
Adjust the damp heat Test Chamber: set the temperature and humidity of the Test Chamber, usually the test temperature is 55°C and the humidity is 95%RH.
Place the oil samples: Place the oil samples in the damp heat Test Chamber and let them run under the set environmental conditions.
Observing the performance of the oil sample: During the test, it is necessary to regularly check the acid value, viscosity, conductivity and other parameters of the oil sample to understand the performance of the oil sample.
Record data: record each detected data and results for data analysis and comparison.
End of test: After the test is completed, the oil samples need to be tested and analyzed to determine their wet heat stability.
With this method, the hygrothermal stability of protective oils can be quickly and accurately assessed, and compliance with relevant standards and requirements can be determined.
