Embodiment 1
[0037]Mix 1 kg of cubic zinc sulfide produced by Sakai Chemical Co., Ltd. with 280 g of sulfur, and then add 1 kg of PETN. Put the mixed explosive 3 into a polyethylene bag, install the fuze 2, and bundle it into a spherical shape. Fill another polyethylene bag with 2kg of deionized water as the blocking layer 4, put the spherical explosive into the water, and seal the bag mouth tightly with polyethylene tape. Hang the explosive 3 that is put into the blocking layer 4 behind the center of the reactor with a diameter of 3m (as shown in Figure 2), close the observation window and exhaust pipe, and evacuate and depressurize the reactor to 0.03m. Pa. After the decompression is completed, the explosion is carried out. After confirming that the pressure in the reactor had become 0.05 MPa, the inlet valve was opened to replace the air in the reactor. Then, 50 L of deionized water was added to the reactor for cleaning, the cleaning solution was filtered and dried, and 360 g of expl...
Embodiment 2
[0039] Except that the hexagonal zinc sulfide produced by 1 kg of "Sakai Chemical" company was used as a raw material, all the other operations were the same as in Example 1, and 312 g of explosive products were recovered. The obtained product was subjected to X-ray crystallographic analysis and TEM observation, the results are shown in accompanying drawings 6 and 7, and it can be seen that the structure of the product is the same as that of Example 1.
Embodiment 3
[0041] Except adopting 500g PETN explosive to mix with zinc sulfide, wrapping outside the mixture with remaining 500g explosive, all the other operations are identical with embodiment 1, reclaimed 382g explosive product. The X-ray crystallographic analysis results and TEM observation results of the explosion product are shown in Figures 8 and 9, and the structure of the product is also the same as in Example 1.
[0042] The present invention is not limited to the above examples.
