The development of the material industry has made non-ferrous metals an indispensable and important material in people's lives, and non-ferrous metal powders have also been widely used, aluminum powder is one of them. Aluminum powder, also known as aluminum silver powder or silver powder, is mainly named because of its silver-white metallic luster. Although it is called silver powder, its chemical composition is still aluminum, not silver. In production and life, aluminum powder has many uses. Aluminum powder has a very high melting point and is often used in refractory materials. Aluminum powder can increase the refractoriness of refractory materials, increase the density, hardness and change other physical properties of the material, and aluminum powder can be used in refractory materials. gas to prevent the bursting that occurs during the sudden temperature rise of the refractory material. Aluminum powder is also widely used in the identification of fingerprints and the production of fireworks. In addition, the application scope of aluminum powder also includes: powder coating, ink, plastic masterbatch, printing, imitation gold paper, imitation gold card, gold film, textiles, but it will be used in water-based paint and paint with acid and alkali. Oxidation and blackening, not recommended for applications requiring acid and alkali resistance and combination with rainwater. Aluminum powder is also widely used in metallurgy, aerospace, chemical and other industries.
