SF6 gaseous tracer is an effective technology for airtight test of voluminous containers. In this work

with SF6 gaseous tracer

the dynamic leakage of a voluminous inter-explosion container was tested. Kr was selected to indicate the loss of SF6 caused by the explosion-caused high temperature. The results showed that the gas leakage for various airtight points occurred a short time after explosion

and attenuated rapidly with time by exponential order to the stable leavl of 10–12–10–13 L/h in 29 hours after the explosion. As a result

the shock wave was considered as the chief matter responsible for gas leak. The material and mechanical structures for airtightness were not damaged.
