Description

technical field [0001] The invention relates to the technical field of detection, in particular to a device and method for testing the hydrogen evolution and absorption performance of oil paste. Background technique [0002] The hydrogen absorption / hydrogen evolution performance index of the ointment refers to the ability of the ointment to absorb or release hydrogen under specified conditions (heating or normal temperature). Hydrogen has a greater impact on optical fiber loss. When hydrogen molecules invade the optical fiber, it will cause a reversible or permanent increase in optical fiber loss. In the optical cable structure, due to the galvanic corrosion of metal materials and the degradation of polymers, hydrogen gas will be generated, and hydrogen gas will accumulate around the optical fiber, which is a potential threat to the hydrogen loss of the optical fiber. [0003] At present, the test methods for hydrogen evolution and hydrogen absorption capacity of ointment a...

Problems solved by technology

For the detection of the amount of hydrogen evolution in cable ointment in Appendix G, the operation steps are complicated, and it is necessary to manually transfer the sample with a syringe many times, and the operation error is large, resulting in inaccurate test results and poor repeatability; in Appendix I, for the hydrogen absorption amount of cable The detection is the calculation result obtained by recording the air pressure value between the samples before and after the treatment, and bringing it into the theoretical formula. The experimental device is complicated, the test process is complicated and the result accuracy is not high
