Aluminum powder is a tasteless and non-toxic silver-white metal pigment, light texture, high buoyancy, excellent hiding power, opaque to light, reflective ability to ultraviolet light, excellent anti-corrosion and water resistance, used in paint, ink and other industries, can also be used as porous concrete air agent.

What is aluminum powder？

Aluminum powder, commonly known as “silver powder”, that is, silver metal pigment, pure aluminum foil added a small amount of lubricant, by ramming crushed into a scaly powder, and then polished. Aluminum powder has the advantages of light weight, high floating force, strong covering power and good reflection performance to light and heat. After treatment, it can also become non-floating aluminum powder. Aluminum powder can be used to identify fingerprints and make fireworks. Aluminum powder is a large category of metal pigments because of its wide use, large demand and many varieties.

Second, the use and role of aluminum powder

The main uses of aluminum powder are: powder coating, ink, plastic masterbatch, printing, imitation gold paper, imitation gold card, gold film, textiles, etc., the use is also extremely wide. However, the use of aluminum powder in water-based paints and acid-alkaline paints will be oxidized and then blackened, so it is not recommended to use aluminum powder for situations requiring acid and alkali resistance and combination with rain.

The role of aluminum powder: aluminum powder is mainly used in pesticides for processing warehouse fumigation agent aluminum phosphide, and can also be made into various specifications of aluminum powder according to customer needs, such as silver paste, aluminum powder paste for aerated concrete, etc. The melting point of aluminum powder is very high, often used in refractories, aluminum powder can increase the refractories, while increasing the density of the material, hardness and change other physical properties, and aluminum powder in the application of refractory materials can discharge the gas in the material, to prevent the explosion in the process of sudden heating of refractory materials.
