   The top of the pyrotechnics contains a combustion agent, a combustion improver, a luminescent agent, and a coloring agent, each of which has its own use. Welcome to the company's official website http://
   The burning agent is made using black powder. The combustion improver is made of aluminum-magnesium alloy, potassium nitrate, barium nitrate or the like. Potassium nitrate , cerium nitrate , etc., decompose as soon as they are subjected to heat, releasing a large amount of oxygen, making the combustion more intense. The luminescent agent is aluminum powder or magnesium powder, and the powder of these metals can be burned violently to emit an incandescent light. The coloring agent is the protagonist in the fireworks. The colorful colors of the fireworks are all based on the hair coloring agent. Many metal salts are able to emit a variety of colors at high temperatures. For example, sodium nitrate and sodium bicarbonate emit yellow light, cerium nitrate emits red light, cerium nitrate emits green light, copper carbonate and copper sulfate emit blue light, and aluminum powder and aluminum-magnesium alloy emit white light. This phenomenon is chemically called a flame reaction.
