Problems solved by technology

[0005] At the same time, the existing core cores will have a "sandwich" phenomenon to varying degrees in the bright bead granulation, that is, the two core cores are glued together and then adhered to the pyrotechnic powder, resulting in the existence of two core cores in the bright bead particles, especially the red light The effect of bright beads is more severe
This kind of bright beads cannot be returned to the furnace for recycling, but can only be discarded and destroyed as waste.

Embodiment 1

[0014] Embodiment 1: the core core that is used for fireworks bright pearl granulation is made up of the component of following weight and number ratio: 10 parts of binding agent; 20 parts of porcelain clay; 30 parts of cement; 50 parts of calcium carbonate. Weigh each component according to the above ratio, put it into the drum for granulation, and install a sprayer in the drum. During the rotation of the drum, the components are mixed evenly, and spray water mist to moisten the composition. After granulation, pass through a 40-mesh sieve. , the undersieve is the core core. There is no potential safety hazard in the core preparation process. The under-sieve core of the 40-mesh standard sieve is a round particle with a particle size of 0.4-0.5mm. Uniform quality and uniform shape. When the core core is used to prepare bright beads, the core core is added to the drum, alcohol is sprayed into the drum during rotation, and pyrotechnic drugs are added to granulate as required. ...

Embodiment 2～7

[0015] Embodiments 2 to 7: The difference with Embodiment 1 is that the component weight and number ratios of the core core are different, as shown in the following table:

[0016] Example Adhesive porcelain clay cement calcium carbonate 2 6 servings 15 copies 25 copies 45 copies 3 7 copies 17 copies 27 copies 48 copies 4 8 servings 22 copies 33 copies 52 copies 5 9 servings 25 copies 35 copies 55 copies 6 10 copies 15 copies 28 copies 46 copies 7 6 servings 24 copies 34 copies 54 copies

[0017] Simultaneously adjust the mesh number of the sieve screen according to the particle size of the manufactured bright beads, such as 20 mesh, 18 mesh, 16 mesh, 14 mesh, 12 mesh, 10 mesh mesh. The particle size of the core used for bright beads with a larger particle size is correspondingly increased, and the particle size range of the core core produced by the composition is about 0.4-2 mm, which...

Abstract

The invention discloses a core nucleus for firework bright bead granulation, which is composed of, by weight, 6-11 parts of a binder, 15-25 parts of porcelain mud, 25-35 parts of cement and 45-55 parts of CaCO3. The raw materials are wetted by water and are uniformly mixed, then are granulated and sieved to prepare the product. The core nucleus is suitable for bright bead granulation by surface features and texture without influence on the burning and setting-off effect of the bright beads. Compared with core nucleus in the prior art, the product can complete the bright bead granulation by a smaller particle size, so that safety risk during a core forming step is avoided, and security of bright bead preparation is greatly improved. The core nucleus is free of mildewing, breaking and sandwiching problems, so that storage and setting-off performances of the bright bead are guaranteed. The method greatly reduces production cost and increases production efficiency.

Description

technical field [0001] The invention relates to the preparation of fireworks bright beads. Background technique [0002] In the prior art, the process steps of fireworks bright beads are: 1) Coring: Pour the powdered pyrotechnic powder into the drum granulator, spray alcohol while the drum rotates, and the powder is formed into small particles, which are obtained after screening. The core with uniform particle size, the particle size of the core is about 2 to 3mm; 2) Bright bead granulation: pour the core into the drum granulator, then pour the powdered pyrotechnic drug, the drum rotates, and the powder in the drum Adhesion effect of core core rotation The pyrotechnic drug rolls bigger and bigger to form bright bead particles. Stop the roller and pour out the bright bead particles. After passing the screening, the finished product of fireworks bright beads will be obtained. [0003] As is well known in the industry, in the preparation process of the above-mentioned bright p...
