The high-low Temperature Test Chamber can be used to test the high-low temperature resistance of bags. Through the long-term exposure of bags in high temperature and low temperature environments, it is possible to simulate the use of bags in different environments, test whether the bags are resistant to high-low temperatures, and whether they can protect the items in the box from temperature changes.
Application meaning
Luggage may be affected by different temperatures during use, for example, it may become hard or brittle in a low temperature environment, while it may become soft or deformed in a high temperature environment. In addition, luggage also needs to consider the protection and preservation performance of its contents at different temperatures. Therefore, in order to ensure the quality and performance of bags, high-low temperature resistance tests are required to test their performance in terms of mechanical properties, physical properties and internal item protection performance at different temperatures, so as to predict and control their behavior in actual use. This can ensure that the bag can maintain its design strength, shape and internal content protection performance under various working conditions, improving its service life and protection performance.
experiment procedure
The test steps of the high-low temperature test box in the high-low temperature resistance test of luggage:
According to the test requirements, the bags are placed in the high-low Temperature Test Chamber, and the test temperature range and time are determined.
Set the high-low Temperature Test Chamber to the set temperature and keep it for a certain period of time to make the case reach the test temperature.
Return the high-low Temperature Test Chamber to normal temperature, and then repeat the above operation, so that the bags experience high temperature, normal temperature and low temperature environment in turn, and each temperature lasts for a certain period of time.
Take out the bag, check whether there is any change on the surface of the bag, such as discoloration, deformation, etc., and check whether the items in the box are damaged or deteriorated.
Evaluate and analyze according to the test results to judge whether the bags meet the requirements of high-low temperature resistance.
Precautions
During the test, it is necessary to ensure that the items in the bag are not affected, and a thermometer and other monitoring instruments can be placed in the bag for monitoring.
During the test process, the stability and accuracy of the high-low Temperature Test Chamber should be guaranteed to ensure the reliability of the test results.
Before the test, carefully read the instruction manual of the bag to understand its operating temperature range in order to set the test conditions.
