活性炭和5A 分子筛是真空绝热容器真空夹层中常用的二种吸附剂。本文根据这两种吸附剂在低温、真空条件下对不同气体吸附特性等资料,对吸附剂在获得并保持低温容器夹层真空度中的作用作了较系统的阐述。
Activated carbon and 5A molecular sieve are two types of adsorbents commonly used in the vacuum interlayer of vacuum insulated containers. In this paper, based on the adsorption properties of these two kinds of adsorbents under low temperature and vacuum conditions, the effects of adsorbents on obtaining and maintaining the vacuum degree of sandwich in the cryogenic vessel were systematically described.
