Problems solved by technology

And when potassium perchlorate is used to replace potassium chlorate to produce firecrackers, because its price is high, the generation production rises, so it affects its promotion and use
And when these materials are fired, large smoke is generated, which affects the visual effect and pollutes the environment.

Abstract

A non-smoke fireworks is prepared from nitro cutton (50-90 wt.%), ammonium perchlorate (10-50) and coloring agent (10-40). Its advantages are high safety, no smoke generation, and low cost.

Description

technical field [0001] The present invention relates to a kind of firework, especially relates to a kind of smokeless firework. Background technique [0002] At present, the oxidants used to produce firecrackers in the market are mainly potassium chlorate, potassium perchlorate, sulfur, and potassium nitrate. As we all know, potassium chlorate is a strong oxidant, because it is an exothermic reaction when it decomposes, so its sensitivity is very high. When it mixes and collides with sulfur, phosphorus, carbon and organic combustibles, it is prone to combustion and explosion. It is dangerous to use. Therefore, when potassium chlorate is used for the production of firecrackers and fireworks, safety accidents are easy to occur, causing personal casualties and property losses. For this reason the State Council issued No. 52 document specially in 2002, prohibiting the production of fireworks and firecrackers prepared with potassium chlorate. And when potassium perchlorate is ...
