Aluminum powder is an important and widely used industrial raw material in modern industry. In 2014, China's raw material aluminum powder demand was about 160,000 tons, and its application fields covered refractories, pigment coatings, ceramic alloys, chemical metallurgy, and military industries. The raw aluminum powder has different appearances under the electron microscope, which are mainly water droplets and irregular shapes. The purity of aluminum is generally between 98-99.9%, and the activity is between 96-99%. Content is the two most important indicators to measure the quality of raw aluminum powder.
       In all raw material aluminum powder applications, the production of coating aluminum powder (that is, pigment aluminum powder) and aluminum powder slurry (that is, aluminum silver slurry) is one of its main application fields. Ton. Coating aluminum powder refers to aluminum powder that has been treated by grinding to form flakes and whose surface is coated to be suitable as a pigment. The coating aluminum powder has a sheet-like appearance, has good physical shielding properties, silver-white metallic luster, and optical effects with different colors, and the pigment aluminum powder coated with advanced fatty acids also has floating performance in the paint film. Aluminum silver paste is a mixture of coating aluminum powder and solvent. Its use characteristics are roughly the same as that of coating aluminum powder. However, due to the historical use of the process, the use of aluminum silver paste is more common, and the production and sales are greater. Advanced technology, fine processing, good effect!
       Therefore, the raw material aluminum powder is the main raw material for the production of aluminum pigments, and does not have the physical shielding properties (hiding power) and metal optical effects (metal gloss) required by aluminum pigments. Coating aluminum powder and aluminum silver paste are two different forms of aluminum pigment. Coating aluminum powder is mainly used to produce powder coatings, while aluminum powder slurry is mainly used to produce solvent-based or water-based coatings.
