Embodiment 1

[0019] Take 15 parts of copper oxide, 45 parts of barium nitrate, 37 parts of aluminum-magnesium alloy powder, and 3 parts of dextrin to make 2-20 mesh particle core medicine; then take 35 parts of potassium nitrate, 15 parts of sulfur, 46 parts of charcoal, paste 4 parts of fine powder are made into igniter; 50 parts of core drug and 50 parts of igniter are mixed to make a columnar drug column and set aside.

[0020] Referring to Fig. 2, Fig. 3, and Fig. 4, the bottom of the launch tube 1 is provided with a propellant 4 and is connected to the fast lead 3 by the quick lead 5, and the upper part of the propellant is provided with 3 columnar charges made of explosives. A perforated cardboard 7 is arranged between the column 6, the propellant 4 and the column 6, and the column is covered with a cardboard 8.

[0021] Referring to Fig. 1, as shown in Fig. 2, take 10 launch tubes 1 with nozzles facing upwards and an inner diameter of Φ3cm and arrange them obliquely in a fan shape a...

Embodiment 2

[0023] Take 45 parts of copper oxide, 15 parts of barium nitrate, 39 parts of aluminum-magnesium alloy powder, and 1 part of dextrin to make 2-20 mesh-sized core medicine; then take 65 parts of potassium nitrate, 2 parts of sulfur, 25 parts of charcoal, and paste 8 parts of essence are made into igniter; 20 parts of core medicine are mixed with 80 parts of igniter to make columnar powder, and other steps are the same as in Example 1.

Embodiment 3

[0025] Take 30 parts of copper oxide, 30 parts of barium nitrate, 37 parts of aluminum-magnesium alloy powder, and 3 parts of dextrin to make 2-20 mesh particle core medicine; then take 50 parts of potassium nitrate, 8 parts of sulfur, 38 parts of charcoal, and paste 4 parts of essence are made into igniter; 40 parts of core drug and 60 parts of igniter are mixed to make a columnar drug column, and the other steps are the same

Abstract

This invention relates to a kind of fireworks with a fan-like flash posy set-off effect including several emission tubes put slanting and arrayed in line, the emission tubes of each line are arrayed in fan, quick-ignition connection is applied among tubes in a same line and slow-ignition connection is applied at ether end between two lines, emission powder and powder posts made of set-off powder are set in the tubes, said set-off powder includes a core, an ignition powder, the weight percentage of the composition in the core is: CuO 15-45%, BaNO3 15-45%, MgAl alloy powder 15-50%, dextrin 1-3%, the weight percentage of each composition in the ignition power is: KNO3 35-65%, sulfur 2-15%, charcoal 20-50%, dextrin 4-8%, said core is mixed in terms of 20-50% weight ratio and the ignition powder is 50-80%.

Description

technical field [0001] The invention relates to a firework with good discharge effect and its discharge medicine. Background technique [0002] Fireworks are deeply loved by the public because of their colorful colors and various shapes in the process of setting off. They are indispensable celebration products in festivals, entertainment and related celebrations, and they also have a wide market. At present, my country's fireworks products have always been an important product for the country to earn foreign exchange through export. As the market has higher and higher requirements for fireworks varieties, it also has higher requirements for quality and discharge effects. This also requires technicians who prepare fireworks products to have more innovations. Although existing fireworks have various discharge effects, there are still some problems that have not been resolved. At present, there is no related fireworks product that can produce a discharge effect that produces a...
