Abstract

The present invention discloses slight smoke type tricolor fireworks powder particles and application. The fireworks powder particles are obtained by the following steps: dissolving nitrocotton and a smokeless powder with the nitrocotton at first; emulsifying, foaming and prilling; then removing a solvent and separating materials; and finally drying to obtaining the fireworks powder particles. The obtained particles are mixed according to the relative mass ratio of (1-8): (1-8): (1-8) to obtain colorful fireworks powder. According to the slight smoke type tricolor fireworks powder particles and the application provided by the present invention, a color addition principle is utilized; the slight smoke type tricolor fireworks powder particles are mixed to match colors; the circumstance that a formula is designed independently according to various colors can be avoided; and only three basic powder particles are required to be produced. The three raw material powders are combined to achieve the colorful effect, the preparation process can be simplified, the product quality is stabilized, the production efficiency is greatly improved, and the production links are simplified.

Description

technical field

[0001] The invention belongs to the technology of fireworks medicine, in particular to a small-smoke-type three-primary-color fireworks medicine granule and a small-smoke-type three-primary-colors little-smoke medicine granule mixed to prepare a small-smoke type color fireworks medicine. Background technique

[0002] Traditional fireworks products are similar, they all contain black gunpowder, medicine primer, and effect medicine, and then add some luminescent and coloring agents to show colorful colors. However, when traditional fireworks products are set off, a large amount of sulfur oxides, nitrogen oxides, and metal particles will be produced. These are all serious air pollutants, which are not accepted in today's society. In addition, due to the application of black powder, the smoke concentration is very high, which seriously affects its discharge effect. Smoke and solid particles produced by combustion are suspended in the air in the form of aerosols,...
