Cold light firework powder column and screw compression forming process thereof

Abstract

The invention discloses a cold light firework powder column and a screw compression forming process thereof, belonging to the field of fireworks and crackers. The screw compression forming process ofthe cold light firework powder column has the beneficial effects that the raw materials are easily available, and the production is relatively safe. The process comprises the following steps: plastifying nitrocotton containing water wine, an oxidant, titanium powder and a functional aid by virtue of a solvent dissolved with a stabilizing agent, so as to obtain a plastified material; compacting theplastified material by virtue of a screw compressor, carrying out compression molding by virtue of a mold, and carrying out airing, cutting and drying, so as to obtain the finished cold light firework powder column. The nitrocotton containing water wine is directly utilized as the raw material, and the proportion of the materials in the plastifying process is adjusted, so that the nitrocotton containing water wine and the other raw materials can be relatively uniformly mixed, the plastified material is relatively compact, and the production process is safe and reliable; and the combustion speed of the prepared powder column is controllable, and the product quality is stable.

Description

technical field [0001] The invention belongs to the field of fireworks and firecrackers, and in particular relates to a cold-light fireworks drug column and a screw press molding process thereof. Background technique [0002] Cold light fireworks, also known as cold fireworks, cold fireworks, fountains, etc., rely on their own chemical combustion jets to produce sound, light, color, sparks and branch sparks when they are set off, forming colorful fireworks effects and artistic shapes. They are highly ornamental and widely used. In group activities such as stage performances, stage design and large-scale festival banquets, fireworks toys, birthday fireworks, etc. Cold light fireworks have the characteristics of low discharge temperature, low product pollution, high safety, and good discharge effect. At present, the cold light fireworks on the market are assembled by uniformly mixing single-base powder or nitrocellulose powder, oxidizing agent, metal powder, etc. with a certa...

AI Technical Summary

Problems solved by technology

One is that the nitrocellulose may decompose and burn due to local overheating during the drying or drying process, resulting in a combustion explosion accident. Such safety accidents have occurred in Liuyang Cold Light Fireworks Factory; The third is that the nitrocellulose is in a fluffy state, and it is not easy to compact after mixing with titanium powder and oxidant, the burning rate is not easy to control, and the discharge operation is more dangerous; the fourth is that the cold light fireworks products have poor storage performance, because the nitrocellulose There is no stabilizer in it, and long-term storage will cause safety accidents due to the self-decomposition of nitrocellulose
