Firecrackers firecrackers are things that roll up gunpowder with paper and block both ends. After lighting the fuse, they can burst and make sound. They are mostly used for festive events. Also known as "firecrackers", "firecrackers" and firecrackers, they are Chinese specialties. Firecrackers originated very early and have a history of more than two thousand years in our country. The earliest firecrackers refer to firecrackers, which are called firecrackers because of the sound of "beep, beep, beep" when bamboo is burned. The main ingredient of firecrackers is black powder, which contains sulfur, charcoal powder, potassium nitrate, and some also contain potassium chlorate. Magnesium powder, iron powder, aluminum powder, antimony powder and inorganic salts are also added when making flash thunder, electric light cannon, fireworks cannon, and colored fireworks. When fireworks and firecrackers are ignited, charcoal powder, sulfur powder, metal powder, etc. will burn rapidly under the action of oxidant, producing carbon dioxide, carbon monoxide, sulfur dioxide, nitrogen monoxide, nitrogen dioxide and other gases and dust of metal oxides. Light and heat cause firecrackers to explode. Paper scraps, smoke and harmful gases are flying around with the sound and flames, filling the site with gunpowder smoke, sulfur oxides, nitrogen oxides, carbon oxides, etc. seriously pollute the air. These gases are irritating to the human respiratory tract and eyes. . Setting off firecrackers during the Spring Festival, as the custom of the Chinese people to celebrate the Spring Festival, has a long history and has become an indispensable part of people's life during the Spring Festival. Although this kind of activity can add a joyous atmosphere to the festival, the smoke and dust released by setting off firecrackers and the sparks splashed are likely to cause environmental pollution and cause fires.
