【 摘 要 】

The self-balancing method of packing container is to connect the packing container with the outside world to achieve pressure balance. The gas entering the packing container has been filtered and dried, and the technology of gas filtration has been mature. Under the open environment, the hygroscopicity of hygroscopicity agent needs to be tested. This paper introduces the requirement of hygroscopicant and the test of hygroscopicant under restraint condition, which is used in the design of self-balancing packaging equipment.
