First, referring to [Fig. 1] to [Fig. 6] and Table 1, the first to sixth embodiments of the explosive charge composition of the present invention include potassium perchlorate having a weight percentage of 40 to 60, and a weight percentage of 10 Silver powder of up to 25 and sulfur with a weight percentage of 5 to 25; in addition, it is possible to further add aluminum-magnesium powder, expanded powder (light calcium carbonate) or carbon powder and a combination thereof in a weight percentage of 10 to 30 as an auxiliary Further, as shown in [Fig. 7], the seventh embodiment of the explosive charge composition of the present invention comprises 50 parts by weight of potassium perchlorate, 5 parts by weight of sulfur and 45 parts by weight of aluminum-magnesium powder.

Based on the constitution, the explosive charge composition of the present invention replaces the conventional potassium chlorate with potassium perchlorate, which can cause the sensitivity of the composition to be changed from high to low, and has the effect of low sensitivity of the composition and thus reducing the risk; further, if further The addition of aluminum-magnesium powder, light calcium carbonate or carbon powder and a combination thereof as an auxiliary agent has the effect of adding an auxiliary agent to enhance the explosion effect.

In addition, referring to [Fig. 8], the explosive device 10a of the present invention is filled with an explosive charge layer 12a and a sealing layer 13a covering the explosive charge layer 12a inside a hollow body 11a, and the sealing layer is sealed. The layer 13a is provided with an ignition lead 14a coupled to the explosive charge layer 12a to form a firecracker structure, and the explosive charge layer 12a is composed of the components of the first to seventh embodiments of the explosive charge composition. Furthermore, referring to [Fig. 9], the explosive device 10b of the present invention is filled with an explosive charge layer 12b, an ignition powder layer 15 and the explosive charge layer 12b and the ignition powder layer inside a hollow body 11b. a cover layer 13b is covered, and an ignition lead 14b connected to the ignition powder layer 15 is bored in the sealing layer 13b to form a pyrotechnic structure, and the explosive charge layer 12b is composed of the foregoing explosive charge composition embodiment 1 to The composition of the seventh embodiment is composed.

In summary, the technical means disclosed in the present invention have the invention patents such as "novelty", "progressiveness" and "available for industrial use", and pray for the patent to encourage the invention. German sense.
