What are fireworks like?
It pollutes the environment, wastes strategic resources, intensifies bribery, endangers public order and threatens life safety.
The pollutants produced by fireworks and fireworks combustion are similar to those emitted by automobile exhaust and coal combustion. Forget firecrackers, it is harmful nitrogen and sulfur compounds; When the colorful luminescent substances of fireworks burn, they will produce more toxic substances. For example, firecrackers should emit particularly bright white light and silver light. In addition to adding aluminum and magnesium, rare earth element titanium should be added. To produce colored light, non-ferrous metals are essential, and heavy metals and rare earth metals have good flame color effects, such as manganese, chromium, nickel, vanadium, molybdenum, tungsten and cerium (the main flint materials of traditional lighters). Smokeless fireworks mainly use nitrocellulose, which has been around for more than 0/00 years. Hunan Province, Jiangxi Province and the Ministry of Science and Technology have invested more than 100 million yuan, and the low-pollution fireworks developed are not up to the level of R small enterprises. Compressed air cold strike (from 15,16th century) fireworks, time programmable preset software and integrated circuit delay electronic ignition fuze (from 1940) are engineering technologies that have been publicly used in this field abroad for more than ten years.
