What are the advantages of nitrogen atomized aluminium powder?

Do you know the advantages of nitrogen atomized aluminium powder? In today's fast-developing aluminium pigment industry, many people are beginning to pay attention to the industry in their spare time. This is because aluminium pigment products are widely used in our daily lives, and people are beginning to pay attention to our aluminium powder. Do you know what aluminium powder is? Do you know the advantages of nitrogen atomized aluminium powder?

What are the advantages of nitrogen atomized aluminium powder? Before we understand the advantages of nitrogen atomized aluminium powder, let's first take a look at what nitrogen atomized aluminium powder is!

Aluminium powder is a silver-white powder that is non-toxic and odorless, and has a strong metallic luster. The aluminium powder particles used in pigments are in a flake shape, and it is precisely because of this flake-like particle state that aluminium powder has metallic luster and shielding properties.

1. Flake-like coverage characteristics. The coverage of nitrogen atomized aluminium powder depends on the size of the surface area, that is, the thickness-to-diameter ratio. During the grinding process, nitrogen atomized aluminium powder is stretched, and the thickness-to-diameter ratio increases, and the coverage increases accordingly.

2. Shielding properties. The pores between each layer of nitrogen atomized aluminium powder overlap with each other, cutting off the capillary pores of the carrier film, and external moisture and gases cannot reach the substrate through the capillary pores. This is the shielding property of nitrogen atomized aluminium powder.

3. Optical characteristics. The pores between each layer of nitrogen atomized aluminium powder overlap with each other, cutting off the micro-capillary pores of the carrier film, and external moisture and gases cannot pass through the capillary pores to reach the substrate. This is the good physical shielding property of aluminium powder.

4. "Bicolor Effect" characteristics. This characteristic of nitrogen atomized aluminium powder has been widely used in coatings, such as hammer paint or metallic paint.

5. Floating properties. One type of pigment nitrogen atomized aluminium powder and aluminium paste is a floating type, whose characteristic is that the flake shape floats on the surface of the coating film.

These are the specific contents of "What are the advantages of nitrogen atomized aluminium powder?" I hope it is helpful to you, we will see you again in the next issue!
