The molecular sieve used in low-temperature containers is a mixture of 13X and 5A molecular sieve,which are important components for ensuring vacuum quality during the service of low-temperature products.But the adsorption of ad-sorbents is physical adsorption,and under specific conditions,it will desorb the previously adsorbed gas,thereby affecting the vacuum degree and low-temperature insulation performance of the container.Especially when the container encounters unexpected situations,which cause vacuum loss and require repair,how to ensure the vacuum quality after repair is crucial for the treatment of adsorbents.Under the designing fixtures and simulating vacuum conditions,testing the desorption ca-pacity at different temperatures,finding suitable disposal solutions,improving vacuum efficiency,and providing strong as-surance for the vacuum quality of repaired products.
