How to make fireworks

Abstract

The invention discloses a making method for fireworks and firecrackers. The making method comprises the steps that (1), a first agent is prepared by using a component A and a component B; first agent particles with each part of the component A as the core and each part of the component B as the skin are made; the outer layer of each part of the first agent particles is wrapped with paper layers, the paper layers are untreated paper and treated paper in sequence from the inside to the outside, and the treated paper is paper soaked in a potassium permanganate solution; the first agent is put into a paper cylinder, and a first agent cylinder is made; (2), a second agent is prepared through a component C and a component D; each part of the component C is put into the corresponding component D, and second agent particles with each part of the component C as the core and each part of the component D as the skin are made; and the second agent is put into a paper cylinder, and a second agent cylinder is made; and (3), the first agent cylinders and the second agent cylinders are inserted into a paper board in a penetrating manner and fixed to the paper board. The fireworks and firecrackers made through the making method are more environmentally-friendly, safer and more colorful when discharged.

Description

technical field [0001] The invention relates to a method for making fireworks and firecrackers. Background technique [0002] Firecrackers are one of the most commonly used festive items. Whether it’s Chinese New Year or festivals, weddings, school promotions, summer completions, or store openings, most people will set off firecrackers to celebrate. The oxidant used in the traditional first medicament is potassium nitrate. In modern times, potassium nitrate is replaced by potassium chlorate as the oxidant. Because the thermal stability of these two oxidants is very poor, it is very easy to cause safety accidents. In 2002, the General Office of the State Council No. 52 The document even stipulates that the use of potassium chlorate is strictly prohibited in the production of fireworks and firecrackers; at the same time, a large amount of sulfur is used as a reducing agent, and sulfur itself is a combustible substance with very active chemical properties, which further reduces...

The oxidant used in the traditional first medicament is potassium nitrate. In modern times, potassium nitrate is replaced by potassium chlorate as the oxidant. Because the thermal stability of these two oxidants is very poor, it is very easy to cause safety accidents. In 2002, the General Office of the State Council No. 52 The document even stipulates that the use of potassium chlorate is strictly prohibited in the production of fireworks and firecrackers; at the same time, a large amount of sulfur is used as a reducing agent, and sulfur itself is a combustible substance with very active chemical properties, which further reduces the stability of the first agent. Produce toxic and harmful sulfur dioxide gas, which affects the environment, so the country restricts its use
