Description
Technical Field
The invention belongs to the technical field of storage and transportation safety protection of explosive and explosive product materials, and relates to an explosive and explosive product storage box, in particular to a safe explosive and explosive product storage box.
Background
For the explosive product, the explosive product is a strategic basic product of national defense science and technology industry, is an important mark for measuring the national equipment level and military strength, and is a power energy and a power energy for launching, driving and damaging various weapon equipment of army, sea, air and rocket troops. The explosive product is one of materials with large consumption in war, and needs to be stored in peaceful period, and the product is required to be used reliably and packaged and unsealed conveniently in war period. Because of the wide range of our country and the large difference between the use and storage environment, the adaptability and the convenience of the explosive products in each circulation link are very important. Due to the characteristics of flammability and explosiveness, the explosive and powder products have high requirements on safety and stability in the processes of production, storage, transportation and use.
Although the current domestic packing materials for explosive and gunpowder products can meet the requirements of storage and transportation of the explosive and gunpowder products and ensure that the quality of the products is not changed in the long-term storage process, the material and the structure of the packing materials are not suitable for the current requirements of the era of rapid development and are more difficult to meet the requirements of automatic and intelligent manufacturing processes of ammunition, so that the upgrading and updating work of the packing materials for explosive and gunpowder products is urgently carried out.
The packaging of explosive products in China developed from the 20 th century to the 50 th era till now can be roughly divided into 3 types: class 1 is represented by threo cases (metal cases are lined in wooden cases), and propellant packages are taken as examples; class 2 is represented by wooden case packaging, exemplified by explosive packaging; category 3 is tissue tube packaging, exemplified by trinitrotoluene packaging.
The Su type box package is a package mode for propellant powder in China, which is basically used since the introduction of explosive product packaging technology from the Soviet Union in the 50 s of the 20 th century. The propellant powder packing material mainly adopts a structure that a metal box is sleeved in a wooden box. The packaging box is divided into a No. 1 box, a No. 2 box and a No. 3 box according to different sizes, wherein the mass of the commonly used No. 1 packaging box is about 23kg, and the medicine loading amount of each box is 70-75 kg.
The packing with wooden case, since the 1 st Hexogen production line of China was put into operation in 1964, the Hexogen product was packed with wooden case, and then with the success of the production of Taian, HMX and various mixed explosive products, Taian, HMX and mixed explosive were packed with wooden case. The inner package of the wooden case package adopts plastic bags and kraft paper bags as packaging materials, the outer package is a wooden case, and the packaging capacity of each case is about 45 kg.
The paper barrel package, in the 90 s of the 20 th century, the organization of the department of military industry after the summation of original soldiers developed the research work of the packing box of explosive products, and the second five factories (representing the southwest area) and the fourth five factories (representing the northeast area) of China carried out the test research of the outer package of the propellant powder composite paper barrel and the inner package of the anti-static plastic film bag, the aluminum-plastic film bag, the polyethylene film bag and the neutral kraft paper respectively. Tests show that the above-mentioned internal packaging bag is compatible with propellant and can be used for packaging of foreign trade products, and in the 20 th century and 80 th century, the paper barrel package is used for packaging of mixed explosive along with the foreign trade products, and the paper barrel package also can be used for packaging mixed explosive
The related standards of the explosive and powder product packaging materials are introduced while the Soviet Union explosive and powder product packaging materials are introduced domestically. The standard of explosive is developed according to the industrial technology in China, the standard of the Soviet Union is basically carried out according to the standard, part of the standard content is adjusted in the standard using process, and the adjusted standard is WJ 24-1976 technical conditions for metal boxes for packing gunpowder, WJ 25-1976 technical conditions for wood boxes for packing gunpowder, WJ 100-1976 technical conditions for recycling packing boxes for packing gunpowder, GJB 636-1988 technical conditions for wooden boxes for packing explosive and W209J 9-1992 paper buckets for packing explosive are formulated in the 20 th century 80 and 90 s and are used up to now.
The current storage box for explosive products has the following defects:
firstly, as the existing storage box is mostly made of solid wood, the storage box made of the solid wood can be burnt together after accidental ignition of explosive products, so that the thermal radiation output of a temperature field is increased, and the thermal stimulation quantity of adjacent products is worse; secondly, no obvious blast wave attenuation measures are provided, and after the product is accidentally exploded, sympathetic explosion risks exist in adjacent products; thirdly, the storage box has insufficient protection strength and shock absorption, so that the explosive and powder products are damaged due to external impact in the storage and transportation processes; fourthly, the box body has no good protection effect on accidental stimulation (fragments, bullets and the like), and has no attenuation interlayer; fifthly, static electricity generated by friction cannot be led out during storage and transportation of the explosive and powder products; sixth, there is no corresponding shielding from the electromagnetic environment.
By combining the above analysis, it can be known that, in the prior art, when the storage box for explosive products is designed, negative stimulation energy (fragments, bullets, thermal radiation, electromagnetic stimulation, shock waves and the like) possibly received by the explosive products in the storage and transportation processes is not considered comprehensively, so that the explosive products cannot be protected comprehensively, and further safety accidents are easily caused in the storage and transportation processes of the explosive products.
