This invention provides a method for the synergistic catalytic thermal decomposition of ammonium perchlorate (AP) based on metal fuels. The method employs a pre-prepared composite metal fuel (C / M), where C is a low-melting-point fuel metal (such as Al, B, etc.) and M is a highly catalytically active metal (such as Ni, Cu, etc.). By uniformly mixing the above fuel with AP in a specific ratio, during heating, the fuel not only provides the heat of reaction as a high-energy fuel, but also, the transition metals and their potentially in-situ generated metal derivatives within it, work synergistically with the low-melting-point metal component to significantly reduce the high-temperature decomposition temperature of AP, greatly increase its decomposition reaction rate, and lower its apparent activation energy. The method described in this invention is simple, has significant catalytic efficiency, and good safety, showing promising application prospects in solid propellant formulations and providing effective technical support for improving propellant combustion performance.

This utility model discloses a screening device for ammonium perchlorate crystal particles, relating to the field of sorting technology. The device includes a discharge box, with a crystal particle screening box slidably connected inside. A particle screening structure is located on the crystal particle screening box. The particle screening structure includes two stepper motors, two rotating shafts, and two cross-shaped screen plates. Both rotating shafts are rotatably connected inside the crystal particle screening box. The two cross-shaped screen plates work alternately. When large particles accumulate on one screen plate, the stepper motor drives its rotation, transferring the large particles to the arc-shaped screen plate. The other screen plate immediately takes over the screening work, ensuring uninterrupted screening. Combined with the vibration of the crystal particle screening box, qualified particles can quickly pass through the screen plates, effectively avoiding the problem of low screening efficiency caused by material accumulation and further increasing the screening volume per unit time.
