The present invention selects component a and component b, contains barium nitrate, contain potassium nitrate, barium nitrate and nitre in component b in component a
Sour potassium can bring the smog of different colours.Phenolic resin in component b and starch ensure that component b can be with molding it is ensured that first
The integrity of pharmacy particle.When setting off, component b of outer layer is first seted off, and sends a kind of smog of color；After intervals,
Component a of internal layer is just burnt, and sends the smog of another kind of color.The firecracker that the present invention prepares is sent when setting off
The smog of different colours discharges successively, thus increased the stereovision of smog color, forms more gorgeous visual effect.
The present invention is made up of two-layer in the outer layer covers ply of paper of each the first pharmacy particle, ply of paper, and outer layer is through too high manganese
The paper that sour potassium solution immersion treatment is crossed makes it is ensured that outer layer can be ignited after-combustion in firecracker；Internal layer be by completely without
The paper managed forms (paper of such as volume gun barrel, or the waste paper of books), and on the one hand it can slow down the first pharmacy particle
Start the time burnt, so that the people lighting firecracker has what the more time left firecracker to set off place, it is to avoid the combustion of firecracker
The people put excessive velocities and lead to light firecracker cannot leave situation about being injured by firecracker in time and occurs；On the other hand, it still may be used
To play the effect of the first pharmacy particle of igniting it is ensured that setting off of firecracker.
Similarly, second medicament granule is also made up of component c and component d, and component d of outer layer is first seted off, component c of internal layer
After set off, thus sending the smog of different colours.And because the first pharmacy particle has ply of paper, therefore, the first pharmacy particle
Can set off compared to after second medicament granule, the smog that this results in four colors when firecracker is seted off is sequentially generated, thus bringing
More gorgeous effect.
