Description
Technical field
The present invention relates to a kind of packing container that detects the splendid attire dangerous cargo and transport the equipment of index safely, refer in particular to the equipment that a kind of plastic packaging containers to the splendid attire dangerous cargo carries out the high temp. congestion test.
Background technology
The result of high temp. congestion test is the important indicator that the plastic packaging containers of detection splendid attire dangerous cargo is transported safely.This detection is finished at high-temperature stacking test device, its detection method is: tested container is placed in the high-temperature stacking test device, in being not less than 40 ℃ environment temperature, apply be equivalent to sample gross weight and the above pile height of 3m weight on tested container, continued to exert pressure 28 days.Then judge that according to outward appearance and the deformation of tested container whether qualified container is.I.e. this test is to simulate the plastic packaging containers of splendid attire dangerous cargo in the long-distance transport way, be under the more abominable high temperature transportation environment, whether packing container can produce gross distortion, causes the seepage of in-built dangerous cargo and caving in of stow and affects the problem of whole transportation safety.
This shows that high-temperature stacking test device is the visual plant of sea-freight outlet Transport Packages of Dangerous Goods check.Its test findings accurately whether, the safety of the whole transportation of direct relation.It is a leading indicator of sea-freight outlet Transport Packages of Dangerous Goods check.
