Oxidation induction time tester is an instrument used to determine the oxidation induction time of polymer materials. The instrument evaluates the thermal stability and oxidation induction rate of the material by measuring the time of the induction period in a high-temperature oxidation environment. In this paper, the basic principle, application method and practical application of the oxidation induction time tester are introduced in detail.

 

First, the basic principle of oxidation induction time tester

The oxidation induction time tester is mainly realized by differential scanning calorimeter technology. To test, the sample is first placed in the tester, heated to a specified temperature in an oxygen atmosphere, and then the time of the oxidation induction period of the sample at that temperature is recorded. In general, the longer the oxidation induction period, the better the thermal stability and oxidation resistance of the material.

Second, the use of oxidation induction time tester

When using the oxidation induction time tester, the following points should be noted:

1. Sample size: The size and shape of the sample should be consistent with the standard sample as far as possible to ensure the accuracy of the test results.

2, temperature scanning range: set the temperature scanning range according to the actual demand, usually 200℃ to 300℃.

3, oxygen atmosphere: the stability of the oxygen atmosphere should be maintained during the test to ensure the reliability of the test results.

4, data processing: According to the actual needs, select the appropriate oxidation induction period time, and combined with other indicators for data analysis.

Third, the application of oxidation induction time tester

The oxidation induction time tester is mainly used in the following aspects in actual production:

1, material screening: Through the oxidation induction time tester, the thermal stability and oxidation resistance of different materials can be evaluated, so as to screen out materials with excellent performance.

2, process optimization: Through the oxidation induction time tester, the best process conditions can be determined, improve production efficiency and reduce costs.

3, product testing: Through the oxidation induction time tester, you can detect the performance of products in high temperature oxidation environment to ensure product quality standards.

 

Iv. Conclusion

As an important tool to evaluate the thermal stability and oxidation resistance of polymer materials, the oxidation induction time tester has wide application value in practical production. Through the use of the instrument, excellent performance of the material can be selected, optimize the production process, to ensure product quality standards. With the continuous development of materials science and instrumental analysis technology, we have reason to believe that the oxidation induction time tester will play a more important role in the future and promote the continuous progress of polymer materials science and technology.
