Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug for preventing explosion of dangerous materials, a dangerous goods storage structure having the same, and an explosive article having the same,

The present invention relates to a plug for preventing explosion of dangerous materials, a dangerous goods storage structure having the same, and more particularly to a plug for preventing explosion of dangerous materials capable of stably inducing combustion or explosion of dangerous materials, .

Examples of dangerous substances including explosives and the like include TNT, composition bombs, and high explosives. It is common for the dangerous goods mentioned to be stored and transported in the state that they do not use the explosives. However, in case of removing the above-mentioned fuse, the dangerous material may be exposed to the outside environment through the opening formed in the removed portion of the fuse, so that the performance may be deteriorated in actual use. During storage and transport of dangerous goods mentioned above, plugs are placed in the openings where the new pipes are removed, thereby blocking the external environment. That is, in the case of actually using the dangerous substance mentioned above, a new pipe is arranged in the opening, and when storing and transporting is carried out, the plug is arranged so as to close the opening portion.

Here, the dangerous goods mentioned may be burned or exploded due to ambient environment, ambient temperature, external impact, etc. during storage and transportation except for actual use. That is, the mentioned dangerous substances may burn or explode due to abnormal reaction of dangerous materials due to the surrounding environment, ambient temperature, external impact, and the like. In particular, when one of the dangerous materials burns or explodes during the storage and transport of a large number of dangerous goods, it may cause a chain explosion of remaining dangerous materials in the vicinity. Accordingly, when the dangerous materials are burned or exploded during transportation or storage of dangerous goods, the mentioned plugs are melted or crushed to secure the openings, and the rise of the flame or gas pressure caused by the abnormal reaction of the dangerous materials is discharged through the opened openings, It is possible to prevent the explosion of dangerous materials together with the container for storing the explosion, and to prevent the explosion of a chain. That is, when any one of the dangerous substances is burned or exploded during the storage and transport of a plurality of dangerous goods, the flame or gas pressure rise due to any one dangerous material is discharged through the opening, It is possible to prevent a hazardous material from exploding, and as a result, it does not affect the remaining dangerous substances in the vicinity, thereby preventing a chain explosion.

An example of the mentioned plug is disclosed in U.S. Patent No. 7,451,703 (hereinafter referred to as 'the cited document'). In particular, the plug disclosed in the cited documents contains an ionomer. However, plugs containing ionomers do not melt easily because of their high melting point. Therefore, a plug containing an ionomer has a limitation in using a dangerous material having a softening point or a flash point lower than the melting point of an ionomer. That is, when a dangerous substance having a softening point or a flash point lower than the melting point of the ionomer is burned or exploded, the plug containing the ionomer can not be melted and the openings are kept in a sealed state. It is because. Further, since the plug containing the ionomer is not a brittle material that is easily broken, it may not be easily broken when the dangerous material explodes. That is, a plug containing an ionomer may melt during the combustion of dangerous materials to secure an opening, but may not secure an opening by not breaking when explosion, not by combustion. The plug containing the ionomer is applicable to small-sized hazardous materials, but it is not easy to apply to explosive-type dangerous materials.
