Explanation

A explosive used in high explosives train to expand or transmit detonation waves and ensure reliable and complete detonation of the main charge. It is a widely used initiating explosives and relative compositions in weapons and ammunition. Its sensitivity to external irritation of I boundary is between the primary explosive and the main charge, while the detonation velocity or pressure is higher than that of the main charge. Generally, booster explosive can be single explosive, such as tetryl and HNS, or composite explosive purified and shaped by adding a certain amount of adhesive, such as A-5, CH-6, JH-14, JO-9, etc. Generally, booster explosive is powder or mould powder, which is then pressing or loaded into the shell for use as required. In the explosion sequence of weapons and ammunition, the booster will transmit and amplify the output energy of primary explosive or detonator to the main charge, thus detonating the warhead, which has a connecting role. In civil blasting equipment, booster explosives are used to amplify the energy of detonators and reliably initiate the main blasting charge. The position of booster explosives in weapons, ammunition, and explosive materials determines their performance requirements in terms of appropriate sensitivity, high output power, and good safety. booster explosive are not only used in conventional weapons and explosive materials, but also indispensable in sophisticated weapons and equipment such as aerospace, missiles, nuclear weapons, etc. Its uses include the following aspects: ① as a detonating tube, booster tube, and expansion tube charge in conventional ammunition fuse systems and civilian blasting equipment; ② Used as explosive devices, synchronous initiation devices, and explosives in missiles, atomic bombs, and spacecraft; ③ In the in-line high explosives train, it is used as primary explosive free detonator charge to replace sensitive primary explosive; ④ It is used as micro detonating cord or trench charge in explosion logic network.
