Glowing effect of fireworks light emission is a main effect of fireworks. Whether it is a lighting agent that can play a role in lighting, or a medicament that can produce a bright star, a medicament that can produce an effect of blinking and extinguishing, the fireworks effect they produce cannot be developed without the light effect.
Fireworks fire color effect When fireworks are burned, in addition to being able to emit light, they also need to produce flames of different colors. The flame color is due to a certain chemical reaction between its components when the fireworks chemical agent burns to generate certain atoms or molecules. These molecules or atoms vibrate at a certain frequency and show a certain wavelength spectrum in the visible spectral range Bands or spectral lines, so that the flame coloring becomes a colored flame, this phenomenon is called "flame color effect".
The sound effect of fireworks discharge Some fireworks agents are ignited in a certain container, and some of them emit flashing thunder from combustion to deflagration; some can produce a pleasant whistle or whistle due to the generated gas from the nozzle ; Some can produce sounds similar to bird calls or humming, we call this phenomenon the "sound effect".
Pyrotechnic effect of fireworks, some chemicals can produce a large amount of gas after burning, can make paper products rotate or rise into the sky, or continuously eject colorful stars, or continuously fire firework parts (such as colorful stars, whistle, etc.), or the shell Exploding, these phenomena are caused by the aerodynamic effect of certain fireworks and firecrackers burning.
Fireworks igniting smoke effect Fireworks chemicals can produce luminescence, flame color, sound and aerodynamic effects when burning, and can also produce smoke effect. In the firework agent containing oxidant, combustible agent and organic dye, due to the reaction of the oxidant and combustible agent during combustion, heat is released, so that the organic dye sublimates directly into vapor, and condenses into colored smoke in the atmosphere. This phenomenon is called "fat". Smoke effect".
