Abstract

The invention discloses a system for acquiring a real-time infrared spectrum in an oscillation test. A temperature in a box body can be controlled by controlling a temperature adjusting system througha controller; a temperature of a sample in an oscillation test is controlled; the controller can control the rotating frequency of a rotary drum, the strain generated by rotation and the rotating force value through a dynamic torque sensor and a driving device; and a sample is clamped on a clamp; the clamp is arranged on the rotary drum, and therefore, the rotating frequency of the sample, the strain generated by rotation and the rotating force value are controlled by the controller, an interference light beam generated by an infrared spectrometer penetrates the oscillated sample in real time, so that the continuous infrared spectrum of the sample under the oscillation test adjustment can be obtained, the adjustment of various oscillation conditions of the sample and the test adjustment under different temperature environments are achieved through the controller, and the continuous infrared spectrogram of the sample under different oscillation test conditions can be obtained in real time to improve the understanding of people on macromolecular chain movement.

Description

technical field

[0001] The invention relates to the technical field of infrared spectrum analysis, and more specifically, relates to a system for acquiring real-time infrared spectrum in an oscillation test. Background technique

[0002] Infrared spectroscopy analyzers are mostly used to test the characteristic groups in the sample, and then determine the structure and type of the sample. However, with the further development of Fourier infrared spectroscopy technology and the in-depth understanding of this technology by scholars, they began to use the original Fourier infrared spectroscopy Infrared spectroscopy technology has improved, and real-time infrared spectroscopy analysis technology has emerged. This technology can reduce the time interval of collecting samples during the infrared spectrum test, and can ensure a higher resolution, thereby improving the practicability of Fourier transform infrared spectroscopy.

[0003] The dynamic mechanical analyzer is to measure ...
