Display shell with modular open-bud charging structure and preparation method thereof

Abstract

The invention discloses a display shell with a modular open-bud charging structure. The display shell comprises an outer shell, a delay ignition harness, bright beads and open-bud powder blocks, wherein the outer shell, the delay ignition harness and the bright beads can be made of traditional materials and have traditional structures; and the open-bud powder blocks are combined and charged in a ball shell, and a hollow structure is formed in the center of the open-bud charging structure. A preparation method of the display shell with the modular open-bud charging structure comprises the following steps of: arranging bright beads to the inner side of the ball shell of the display shell; directly charging the prepared modular powder blocks into one semi-ball shell; charging powder into theother semi-ball shell with the same powder charging sequence; and buckling the two semi-modular blocks with each other, and applying paper to the surface of the shell and drying. The display shell structure and the preparation method contribute to overall ignition, the problem of insufficient combustion or powder residue when particular microporous firework powder is taken as open-bud powder can be completely solved, and the enjoyment effect and environmentally friendly performance are improved. Furthermore, the operation of the display shell production process is simplified, and the safety of manufacture process and storage and transportation process of firework products is improved.

Description

technical field [0001] The invention belongs to the bud opening technology of fireworks bombs, in particular to a fireworks bomb with a modular bud opening charging structure and a preparation method thereof. Background technique [0002] At present, due to its environmental protection and safe use, smokeless fireworks have become an ideal substitute for black powder for fireworks or other propellant charges, and have been highly valued by the fireworks and firecracker industry. However, the use of smokeless fireworks with a micropore structure as the bud-opening drug has an unsatisfactory bud-opening effect. The main problem is that the ignition performance is not ideal, and the firing rate of bright beads is low when the charging conditions are not suitable. , the explosion diameter is too small to reach the effect of traditional budding medicines. In the preparation process of granular micropore fireworks, the above problems cannot be completely solved by adding sensitiz...

AI Technical Summary

Problems solved by technology

However, the use of smokeless fireworks with a micropore structure as the bud-opening drug has an unsatisfactory bud-opening effect. The main problem is that the ignition performance is not ideal, and the firing rate of bright beads is low when the charging conditions are not suitable. , the diameter of the explosion is too small to achieve the effect of traditional budding medicines

In the preparation process of granular microporous fireworks, the above problems cannot be completely solved by adding sensitizers or ignition performance enhancers.

In addition, when using granular microporous smokeless fireworks medicine directly as a bud opening medicine for making fireworks shells, each shot needs to be weighed in advance, and the particles are prone to static electricity and adhere to the surroundings of the shell shell, which brings great pressure to the charge. Some difficulties have been raised, and these problems have brought potential safety hazards in the production process of fireworks shells

In addition, the use of granular fireworks charges often leads to the problem of drug particles remaining during the discharge process, which is also unfavorable to the safety and environmental protection of the discharge process.
