Pyrotechnics is a science. Its result allows to provide an exceptional touch of fireworks during the holidays. It would be better to know more about it.
What do we need to know about pyrotechnics?
What is pyrotechnics?
Pyrotechnics is defined above all as the art of using fire. We find it especially in the fireworks that are sent during the festivities. But it is also found in weapons of war, mines, distress signals used by sailors, and even in the aerospace industry.
Types of pyrotechnics
The subject of pyrotechnics or fireworks includes all pyrotechnic devices. These machines are very different in terms of use and specificity.
Compact fireworks
Also known as a fire battery, the compact fireworks display is made up of a set of tubes stacked on top of one another, which, joined together to form a square or rectangle, can vary in number. Compact fireworks are tools to detonate a set of various pyrotechnic effects.
Its system connects the assembly of one or more mortars with a single wick. When ignited, it is a mortar that triggers the ignition of the next one. Compact fireworks are distinguished by successive explosions. Its effect can last between 20 and 50 seconds, depending on the number of assembled mortars.
Candle fireworks
Unlike the compact fireworks display, the candle fireworks display has only one tube. It is in the latter that they are assembled and stacked one on top of the other to form a pyrotechnic effect.
The most accurate example is the pump. The bomb are pyrotechnic effects stacked on top of each other. It has a long wick. And when this is on, the effects are launched into the air, one after another.
Automatic fireworks
Automatic fireworks, also called ready-to-fire, is a type of pyrotechnics, unlike the others, it comes in the form of a suitcase. This pyrotechnics is a complete program. It can last several minutes. For its start-up, its automation activated through an ignition point offers the most spectacular effects that can be seen from a distance.
The components that offer the colors
Several components are assembled so that the product can give diversified colors. We can mention oxidants based on potassium nitrate, potassium perchlorate or strontium nitrate, we can also find the presence of fuel that has the function of controlling the heat and the speed of propagation of the effects. Among the components, we can detect the presence of sulfur, charcoal or aluminum dust.
Colors vary by component, so potassium perchlorate and red gum will give a red color. And the same goes for the combination of strontium and magnalium nitrate. On the other hand, barium bicarbonate gives a green color that can turn blue with the addition of copper oxide.
