Rubber is a common elastic material widely used in various industrial fields such as automotive, electronics, construction, etc. Since rubber is often used in different temperature environments, such as high temperature or low temperature environments, high-low temperature resistance tests are required to test the physical and chemical properties of rubber at different temperatures, such as hardness, ductility, strength, aging resistance Performance, etc., so as to ensure the performance and reliability of rubber in different environments. In addition, the high-low temperature resistance test can also test the durability and stability of rubber, such as wear resistance, corrosion resistance, etc., so as to ensure that the rubber will not be deformed, aged, cracked, etc. during long-term use, and ensure the safety of rubber products sex and reliability.
The high-low Temperature Test Chamber is used to test the performance and stability of rubber materials in high-low temperature environments to evaluate their scope of application and service life. Such tests can simulate the performance of rubber materials at different ambient temperatures to determine whether they meet the requirements for use.
experiment procedure
(1) Place the rubber sample to be tested in a high-low Temperature Test Chamber, and adjust the temperature of the Test Chamber to a set high temperature value (eg 100°C).
(2) Keep the temperature stable for a period of time (such as 2 hours), and then adjust the temperature of the Test Chamber to the set low temperature value (such as -40°C).
(3) Keep the temperature stable for a period of time (for example, 2 hours), and then adjust the temperature of the Test Chamber back to the set high temperature value.
(4) Repeat the above process several times to test the performance and stability of the rubber sample under alternating high-low temperature environments.
(5) During the test, the parameters of the rubber sample can be monitored and recorded, such as hardness, tensile strength, elongation at break, tensile strength, tear strength, etc.
(6) After the test is completed, evaluate the performance parameters and stability of the rubber sample to determine whether it meets the requirements for use.
NBCHAO reminds you: the high-low temperature test parameters and test standards of different types of rubber materials may be different, and the specific test steps should be adjusted according to the product type and relevant standards. At the same time, sufficient safety measures need to be taken before the test to ensure that no safety accidents will occur during the test.
