Firework Aluminium Powder
Silvery-white scaly powder. It has a relative density of 2.55, a melting point of 685°C, and a boiling point of 2065°C. Since fatty acids are adsorbed on the surface of the aluminum powder, it can easily float in liquids. The scaly aluminum powder particles have a ratio of diameter to thickness of approximately 100:1. Moreover, after the aluminum powder is dispersed in the carrier, it has the characteristic of being parallel to the substrate. Many particles are connected, and large and small particles fill each other to form a continuous metal film, which reflects external light and has excellent covering power. The continuous metal film formed by the aluminum powder can be arranged in multiple parallel layers within the carrier film, cutting off the capillary pores of the film-forming material, thereby providing a good shielding effect. It has the ability to reflect ultraviolet, infrared, and visible light and can dissipate heat from sunlight. Aluminum powder pigments have excellent "two-tone effect" characteristics and good weather resistance. They are soluble in acids or alkalis, and react with acids to produce hydrogen.
Flaky aluminum powder is mainly used in fireworks, firecrackers, aerated bricks, etc.
When used in fireworks and firecrackers, flaky aluminum powder not only improves the quality and aesthetics of the products but also enhances the combustion efficiency and safety. With continuous technological advancements and the expansion of production scale, the application of flaky aluminum powder in the fireworks and firecrackers industry will become more extensive and in - depth. In the future, with the increasing environmental protection requirements, the sustainable development of flaky aluminum powder will also become a key research direction.
As a high - performance material, flaky powder shows great potential and advantages in the fireworks industry. Through continuous technological innovation and application promotion, flaky aluminum powder will play a more important role in the fireworks and firecrackers industry.
