摘要	The insulation materials and metal materials in high vacuum multilayer insulation cryogenic equipment released hydrogen into the interlayer for a long time, which led to the deterioration of the insulation vacuum and seriously affect the insulation performance of the container. In this paper, an experimental device was set up through testing the change of vacuum degree, then compared the adsorption performance of Ag-Z getter and high efficiency composite hydrogen getter(ECG). The adsorption isotherm curves of hydrogen getters were obtained. The research defined that the adsorption process of hydrogen getters accords with the first type of BDDT theory, namely Langmuir adsorption. The cumulative insulation capacity of Ag-Z getter was 63.084 mL/g, and the average adsorption rate was 0.132 mL/(g•h). And ECG was 366.276 mL/g and 1.353 mL/(g•h), which was 5.81 times and 10.25 times of Ag-Z getter, respectively. Moreover, with the increased of initial H2 pressure the average adsorption rate of each group increased and then decreased. The maximum adsorption rate of the two hydrogen getters occurred in the first hydrogenation, and the equilibrium pressure of the hydrogen getters increased with the initial pressure of H2. The experimental results provi-ded a basis for the application of two kinds of hydrogen getters in cryogenic equipment and transportation industry. © 2021, Materials Review Magazine.
