Liaoning aluminum powder manufacturer introduces the shielding characteristics of aluminum powder. Ultra fine aluminum powder

The aluminum powder dispersed in the carrier undergoes floating motion, and the result of its motion always makes itself parallel to the substrate coated by the carrier, forming a continuous aluminum powder layer, and this aluminum powder layer is arranged in multiple parallel layers within the carrier film. The pores between each layer of aluminum powder are staggered, cutting off the capillary pores of the carrier film. External moisture and gas cannot pass through the capillary pores to reach the substrate. This characteristic is the good physical shielding of aluminum powder.

Liaoning aluminum powder manufacturer introduces the optical properties of aluminum powder to you

Aluminum powder is made of aluminum with light color and high metallic luster. Its surface is smooth and can reflect 60% -90% of visible light, ultraviolet light, and infrared light. When objects are coated with coatings containing aluminum powder, their surface is silver white and bright, which is the characteristic of aluminum powder reflecting light.

The characteristic of scale like covering

Aluminum powder particles are in the form of scales, with a diameter to thickness ratio of approximately (40:1) - (100:1). After being dispersed on the carrier, aluminum powder has the characteristic of being parallel to the substrate. Numerous aluminum powders are connected to each other, and the large and small particles fill each other to form a continuous metal film, covering the substrate and reflecting the light outside the coating. This is the unique covering power of aluminum powder. The size of aluminum powder coverage depends on the surface area, which is the diameter to thickness ratio. Aluminum is stretched during the grinding process, with an increasing diameter to thickness ratio and a corresponding increase in covering power.

The aluminum powder used for pigments refers to aluminum powder with particles in the form of scales, which is coated with surface treatment agents and suitable for use as pigments in Inner Mongolia aluminum powder wholesale. Aluminum powder slurry is a mixture of pigment aluminum powder and solvent. Its use and characteristics are roughly the same as aluminum powder. Due to its ease of use, it has a larger yield and dosage. Compared with other pigments, aluminum powder used for wholesale pigment in Inner Mongolia has its own characteristics.
