Fireworks production process
1, subpackaging, mixing potassium nitrate, potassium perchlorate and potassium chlorate according to a fixed ratio, and putting them into an instrument to react into pellets. 2. After the pellets are molded, they are made into bright beads and wrapped with a layer of black ignition powder. 3, charging, put the coal ball into the shell of the fireworks, and then seal it with tape. 4. Wires and fuses, and then put on the outer packaging.
The pyrotechnic structure contains black powder and propellant. After the fireworks are ignited, the fuel is pushed into the launch tube and the fuel is confined in a certain space. The accumulated heat and gas will produce strong tension in the launch tube. During the explosion, the air expanded rapidly, pushing the fireworks, producing a huge initial velocity and rushing into the sky. A chemical reaction causes an explosion, and most of the energy released during the explosion is converted into light energy.
Types of fireworks, such as spray, spin, off-line, rocket, spit beads, small fireworks, smoke, modeling toys, combined fireworks, incense burning, friction guns, fireworks bombs, etc. Specifically, it can be divided into cold fireworks, fireworks, potted flowers, Roman candlelight, rockets, electro-optic fireworks, stage fireworks, cold fireworks, instant fireworks, torch fireworks, toy fireworks, firecrackers, stage fountains, shelf fireworks and daytime fireworks.
