Description

Technical Field

[0001] This application relates to the field of fireworks beads technology, and in particular to a fireworks bead for achieving a snow waterfall effect and a method for its preparation. Background Technology

[0002] Snow waterfall (or silver waterfall) fireworks are a commonly used effect in fireworks displays and festival celebrations, with stable market demand. Traditional waterfall effects are typically created by burning bright beads with a specific formula in the air, producing hot, molten material that falls. However, existing technologies generally suffer from the following drawbacks, severely limiting their artistic expression and market satisfaction.

[0003] Firstly, the burning rate is too fast, resulting in insufficient visual effect. The traditional bright beads' formula and combustion design are not entirely reasonable, causing the chemical energy release to be too concentrated and intense after being launched into the air. The resulting waterfall effect is often "fleeting," ending before the audience can fully appreciate it, failing to create a spectacular waterfall landscape with a sense of delayed beauty.

[0004] Secondly, the flowing lines are sparse, thin, and lack fullness. Limited by traditional formulas and processes, the total amount of molten material (i.e., the material forming the lines) produced when the bright beads burn is insufficient, and the spray force and continuity are also poor. This results in a "waterfall" in the air that is not full, continuous, and has a curtain-like feel, but rather several separate, weak trails resembling "rain threads" or "willow branches," with a loose visual effect, lacking density, and having low impact and scene simulation. Summary of the Invention

[0005] The technical problem to be solved by this application is to provide a firework bead for achieving a snow waterfall effect and a preparation method, in view of the above-mentioned shortcomings of the prior art.

[0006] A firework sparkler for achieving a snow waterfall effect includes: an effect core and an ignition layer encapsulating the effect core;

[0007] The active ingredient core comprises the following raw materials and corresponding mass parts: 35-55 parts potassium perchlorate, 0-20 parts aluminum powder, 7-12 parts phenolic resin, 25-50 parts gray aluminum powder, and 0-10 parts coarse alloy powder.

[0008] The ignition layer comprises the following raw materials and corresponding mass parts: 60-70 parts black powder, 15-25 parts potassium perchlorate, 8-12 parts magnesium-aluminum alloy powder, and 8-10 parts phenolic resin.

[0009] Optionally, the raw materials and corresponding mass parts of the active ingredient core are as follows: 35 parts potassium perchlorate, 10 parts aluminum powder, 50 parts gray aluminum powder, 5 parts crude alloy, and 10 parts phenolic resin.

[0010] Optionally, the ignition layer comprises the following raw materials and corresponding mass parts: 70 parts black powder, 15 parts potassium perchlorate, 8 parts magnesium-aluminum alloy powder, and 8 parts phenolic resin.

[0011] Optionally, the firework beads are spherical with an outer diameter of 3-16 mm, and the ignition layer has a thickness of 0.5-1 mm.

[0012] Optionally, the firework beads are constructed in a cylindrical shape with a diameter of 6-50 mm.

[0013] This application also provides a method for preparing fireworks sparklers, the method being used to prepare the aforementioned fireworks sparklers; the method includes:

[0014] Step S10: Use the raw materials of the effect core and prepare the effect core according to the corresponding mass proportions;

[0015] Step S20: Use the raw materials of the ignition layer to prepare the ignition charge according to the corresponding mass proportions;

[0016] Step S30: The igniter is wrapped around the igniter layer formed on the outer layer of the effect core.

[0017] Optionally, step S10 includes:

[0018] Step S11a: Mix the raw materials evenly according to the proportion;

[0019] Step S12a: Add alcohol to the mixed powder to moisten it;

[0020] Step S13a: The humidified mixed powder is loaded into a mold and pressed into a medicine column;

[0021] Step S14a: The compressed drug column is placed in a drying room for drying.

[0022] Optionally, step S10 includes:

[0023] Step S11b: Mix the raw materials evenly according to the proportion, pour the evenly mixed drug into the granulator, and then add alcohol;

[0024] In step S12b, granulation is performed using a granulator to form round beads, which are then screened for uniformity.

[0025] Optionally, step S20 specifically involves: mixing the raw materials for the ignition layer evenly according to the corresponding mass parts to form the ignition charge for making the ignition layer.

[0026] Optionally, step S30 specifically includes:

[0027] Step S31: Place the solvent and the active ingredient core together into the granulator;

[0028] Step S32: Add the evenly mixed igniter, so that the igniter is evenly coated on the active ingredient core to form an igniter layer;

[0029] Step S33: Dry the bright beads to obtain the finished bright beads.

[0030] The purpose of this invention is to provide a snow waterfall firework bead with a moderate burning time, a full and dense effect, and the ability to present a visual effect of falling snow particles, as well as a method for its preparation.

[0031] First, it significantly extends the visual dwell time in the air: By optimizing the formula components to regulate combustion reaction kinetics and adjusting the structure of the bright beads through specific processes, the combustion rate of the bright beads in this invention is effectively controlled. Actual testing shows that the duration of the aerial effect from ignition to the end of combustion is much longer, achieving a significant increase in viewing time compared to the original "fleeting" effect, allowing the spectacular snow waterfall landscape to be fully displayed.

[0032] Secondly, the form and texture of the waterfall effect have been completely upgraded: thanks to the increased content of raw materials in the formula, the trajectory of the falling in the air maintains the continuity and surface curtain feel of a cascading waterfall, while incorporating the dynamic and shimmering texture of a meteor shower. It completely breaks away from the thin form of the traditional "drizzle", presenting a full, dense, and shocking visual effect as if a large number of snow particles are falling, achieving a qualitative leap in visual impact and artistic beauty.

[0033] Third, the effect is stable and consistent, with high reliability: Strict screening, mixing, particle size control, and surface treatment processes ensure highly uniform physical and combustion properties of the mass-produced bright beads. This guarantees that each ignition reproduces a beautiful, stable, and consistent snow waterfall effect, greatly enhancing product reliability and visual appeal. Attached Figure Description

[0036] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0037] It should be noted that, where there is no conflict, the embodiments and features described in this application can be combined with each other.

[0038] Traditional waterfall effects are typically created by burning specially formulated bright beads in the air, producing a hot, molten substance that falls downwards. However, existing technologies generally suffer from the following drawbacks, severely limiting their artistic expression and market appeal. Therefore, this application provides a snow waterfall fireworks bright bead with a moderate burning time, a full and dense effect, and capable of creating a visual effect resembling falling snowflakes, along with its preparation method.

[0039] This application provides a firework sparkler for achieving a snow waterfall effect, see reference. Figure 1 Firework beads consist of an effect core and an ignition layer that encapsulates the effect core.

[0040] The active ingredient core comprises the following raw materials and their corresponding mass parts: 35-55 parts potassium perchlorate, 0-20 parts aluminum powder, 7-12 parts phenolic resin, 25-50 parts gray aluminum powder, and 0-10 parts coarse alloy powder.

[0041] The ignition layer comprises the following raw materials and their corresponding mass parts: 60-70 parts black powder, 15-25 parts potassium perchlorate, 8-12 parts magnesium-aluminum alloy powder, and 8-10 parts phenolic resin.

[0042] In one embodiment of this application, the raw materials and corresponding mass parts of the effect core are specifically: 35 parts potassium perchlorate, 10 parts aluminum powder, 50 parts gray aluminum powder, 5 parts coarse alloy powder, and 10 parts phenolic resin.

[0043] In one embodiment of this application, the raw materials and corresponding mass parts of the ignition layer are specifically: 70 parts of black powder, 15 parts of potassium perchlorate, 8 parts of magnesium-aluminum alloy powder, and 8 parts of phenolic resin.

[0044] In one embodiment of this application, the firework beads are constructed in the shape of spheres with an outer diameter of 3-16 mm and an ignition layer thickness of 0.5-1 mm.

[0045] In one embodiment of this application, the firework beads are constructed in a cylindrical shape with a diameter of 6-50 mm.

[0046] The first step in making fireworks beads is mixing: The metallic combustible agent (aluminum powder, gray aluminum powder, coarse alloy powder) and oxidizer (potassium perchlorate) are mixed evenly to ensure the metallic combustible agent uniformly coats the oxidizer particles. The second step is forming the effect core: The evenly mixed powder and solvent are moistened and fed into a granulator for extrusion granulation under specific pressure, or the granulator is used for compaction. The density and morphology of the resulting beads are adjusted by controlling the pressure and time. The third step is particle size control and drying: The extruded or compacted effect cores are sieved using a standard sieve, and those with particle sizes within a predetermined range are dried at low temperature. The fourth step is surface treatment: The sieved effect core beads are placed in a granulator and coated with a solvent to finely adjust their ignition and combustion rates, resulting in the final finished fireworks beads.

[0047] The finished bright beads prepared in this embodiment were loaded into the fireworks effect inner tube in a conventional manner for ignition testing. The observation results showed that the bright beads burned for a longer period of time in the air, producing a dense and full effect. A large number of bright, hot particles fell continuously, forming an extremely realistic and spectacular snow waterfall scene with a strong visual impact, and the effect was consistent between batches.
