Environmental protection fireworks is a kind of fireworks that does not use substances containing heavy metals and sulfur in the formula of fireworks and firecrackers, and the production of sulfur dioxide and other sulfides in fireworks is reduced. Secondly, it also reduces the consumption of metal powder, and organic matter is basically used as combustible, thus reducing the inhalable particulate matter produced after the combustion of metal powder. It also changes the oxygen balance and combustion temperature of the system, and controls the fireworks combustion reaction by changing the amount of oxidant and combustible.

Characteristics of environmental protection fireworks:

Replace environmental protection fireworks with new environmental protection materials? Paper shell pressure chamber? Use compressed air instead of gunpowder. Traditional fireworks are sealed with paper shells, and the sealing effect of new environmental protection materials is stronger than that of paper shells, which can be completely burned out at the moment of fireworks initiation; Replacing gunpowder with compressed air is the aviation technical basis of Shenzhou VI. By controlling the explosive force generated by compressed air and spraying fireworks, pungent smell and smoke, these environmental pollution problems will be solved.

Safety of environmental protection fireworks;

Environmental protection fireworks rely on the sound, light, color, spark and branch spark generated by the combustion of their own chemicals to form colorful fireworks artistic modeling, which is excellent in viewing.
