AI Technical Summary
Traditional firecrackers cause serious environmental pollution and fire risks due to burning black gunpowder. Existing environmental protection alternatives such as electronic firecrackers lack real experience and are costly, and the cold fireworks have a single effect, making it difficult to have both environmental protection, safety and traditional explosive effects.
Through the redox reaction of potassium permanganate and hydrogen peroxide, a controlled explosion is triggered by rapid release of gas. The shell adopts degradable materials, and the reaction chamber is designed as a three-chamber structure, isolation layer and safety control device to avoid accidental explosions.
It achieves a low-pollution, safe and efficient explosion effect, the products are harmless, and the shell is degradable, reducing environmental pollution and transportation risks, while reducing costs.

Abstract
Description
Technical Field
[0001] The invention relates to the field of fireworks explosion, in particular to a low-pollution firecracker based on the reaction of potassium permanganate and hydrogen peroxide, which realizes the explosion effect through controllable chemical reaction and significantly reduces the pollution of traditional firecrackers to the environment. Background Art
[0002] Traditional firecrackers rely on the combustion and explosion of black powder (sulfur, saltpeter, charcoal), which produces a large amount of sulfur oxides, particulate matter and heavy metal residues, which seriously pollute the air and easily cause fires. Existing environmentally friendly alternatives such as electronic firecrackers lack a real experience, and cold fireworks have problems such as single effect and high cost. Therefore, there is an urgent need for a firecracker that combines environmental safety with traditional explosive effects. Summary of the invention
[0003] 1. Technical Principle The core of the present invention is to utilize potassium permanganate ( ) and hydrogen peroxide ( )'s redox reaction generates pressure and causes explosion by rapidly releasing gas. The specific reaction is as follows:
[0004] The present invention uses solid potassium permanganate powder to react with damp solid hydrogen peroxide powder, violently releasing a large amount of oxygen in a short period of time, resulting in a sudden increase in pressure in the sealed container. When the pressure exceeds the bearing limit of the shell, a controlled explosion is triggered by the intermolecular repulsion and gas expansion. The products are only manganese dioxide, water, potassium hydroxide and oxygen, and no harmful gas or solid remains.
[0005] 2. Structural design Shell: Made of degradable materials (such as biodegradable plastics), with a thickness of 0.2~0.5mm to ensure pressure-bearing strength and environmental protection.
[0006] Reaction chamber: There are three chambers inside. The first chamber stores potassium permanganate solid powder, the second chamber is an isolation layer, and the third chamber stores solid hydrogen peroxide powder and an equal amount of water vapor to make it damp.
[0007] Safety control device: The potassium permanganate layer and the solid hydrogen peroxide layer are separated by two layers of cellulose paper to avoid accidental explosion.
[0008] 3. Advantages of the invention Low pollution: The reaction products are environmentally friendly substances (such as MnO 2 It can be recycled as a battery raw material), and its shell is also made of degradable material to reduce environmental pollution.
[0009] High safety: no risk of ignition by open flame, strong stability in transportation and storage.
[0010] Low cost: Raw materials are easily available, low cost, and easy to promote BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the structure of a single low-pollution and environmentally friendly firecracker of the present invention.
[0012] In the figure: 1. Shell 2. Lead wire 3, 4. Isolation membrane 5 Potassium permanganate cavity 6 Isolation cavity 7 Hydrogen peroxide cavity DETAILED DESCRIPTION
[0013] like Figure 1 As shown, the present invention includes a housing 1, a lead 2, isolation membranes 3 and 4, a potassium permanganate chamber 5, an isolation chamber 6, and a hydrogen peroxide chamber 7. As for the interior of the housing 1, the isolation membranes 3 and 4 divide the interior into three parts, and the lower surface of the isolation membrane 4 has a nano coating to ensure that it is not damp and fully burns. The potassium permanganate chamber 5 contains potassium permanganate, and the hydrogen peroxide chamber 7 contains solid hydrogen peroxide powder and water vapor of the same mass, and the isolation chamber 6 isolates them. The lead 2 connects the isolation membranes 3 and 4.
[0014] Directions: When in use, the fuse 2 is ignited, the fuse 2 burns and ignites the isolation membranes 3 and 4, and the potassium permanganate reacts violently with the damp solid hydrogen peroxide powder. This causes the casing to rupture, producing an explosion and flash. Example
[0015] 1. Prepare a degradable plastic shell.
[0016] 2. The potassium permanganate chamber 5 is filled with potassium permanganate (0.2 g), and the hydrogen peroxide chamber 7 is filled with solid hydrogen peroxide powder (0.5 g) and water vapor (0.5 g).
[0017] 3. When the isolating membranes 3 and 4 are made of cellulose paper and the fuse burns, the isolating membrane is ignited and disappears (a nano coating is applied on the lower surface of the isolating membrane 4 to ensure that the isolating membrane 4 is not damp and burns fully).
[0018] Test effect: The firecrackers exploded rapidly, producing explosion sounds and flashes.
