The origin of fireworks?
Matters needing attention
Flame reaction has a serious disadvantage, that is, it usually requires high temperature. Therefore, the fireworks of the fireworks party have a high temperature. Generally, in this process, metallic combustible materials, such as aluminum and magnesium, are used to reach such temperatures. When aluminum burns, it releases a lot of heat and even melts iron (melting point is about 1500℃). Even if the residue of fireworks falls to the ground, the internal temperature can reach 300℃.
Therefore, it is very important to set a safe distance. However, as a part of China culture, fireworks have irreplaceable influence and spread all over the world. As long as it is used reasonably and transported, purchased, stored and set off according to the operating rules of fireworks, the danger of fireworks is completely controllable.
