Styrene-butadiene rubber is a commonly used synthetic rubber. It has good heat resistance, cold resistance, and chemical corrosion resistance. It is widely used in automobiles, construction, electrical and other fields. The high-low temperature resistance test is to verify the performance and stability of styrene-butadiene rubber at extreme temperatures. In high temperature environments, SBR may soften or swell, while in low temperature environments, SBR may become hard or brittle, resulting in reduced durability and sealing performance. Through the high-low temperature resistance test, the performance and stability of styrene-butadiene rubber in different temperature environments can be evaluated, and high-quality styrene-butadiene rubber materials can be provided for applications in automotive, construction, electrical and other fields to ensure the stability of products in various extreme environments Performance and reliability The high-low Temperature Test Chamber can be used for high-low temperature resistance tests of styrene-butadiene rubber to evaluate its performance and stability in extreme temperature environments.
experiment method
The following are the general steps of the high-low temperature resistance test of styrene-butadiene rubber:
Prepare the styrene-butadiene rubber sample, and prepare according to relevant standards and specifications, including preparation, cutting, punching, etc.
Put the styrene-butadiene rubber sample into the high-low Temperature Test Chamber, and install and fix it according to the relevant requirements.
Set the temperature and time parameters of the high-low Temperature Test Chamber, and set them according to the test requirements and specifications. Generally speaking, the temperature range of the high-low Temperature Test Chamber is between -70°C and 200°C.
When the test is started, the high-low Temperature Test Chamber will automatically heat and cool, and perform cycle tests according to the preset temperature and time parameters. Generally speaking, the high-low temperature resistance test requires multiple cycle tests to simulate environmental changes under long-term use.
During the test, the performance and stability of styrene-butadiene rubber can be evaluated by measuring various parameters, such as tensile strength, hardness, elongation at break, volume change rate, etc.
After the test, take out the styrene-butadiene rubber sample for appearance and performance inspection, such as checking whether there are cracks, embrittlement, deformation and other problems.
Data analysis and evaluation are carried out according to the test results to determine the performance and stability of styrene-butadiene rubber under high-low temperature conditions.
In short, the high-low Temperature Test Chamber can help enterprises and institutions to carry out effective and accurate testing and evaluation in the high-low temperature resistance test of styrene butadiene rubber, and provide strong support for the application and development of styrene butadiene rubber materials.
