What is Atomized Aluminum Powder? As aluminum powder is widely used in heavy industry, many industries have begun to pay attention to aluminum powder. We all know that aluminum powder is divided into ball milled aluminum powder and atomized aluminum powder. Atomized aluminum powder requires a higher process. In the process of atomization, many aluminum powders are prone to abnormal phenomena such as clogging of nozzles, stringers, reverse sprays, and gunshots. So, then what is atomized aluminum powder?
When we understand aluminum powder, we first need to understand the characteristics of atomized aluminum powder, and then understand the production process of atomized aluminum powder. Usually the appearance of aluminum powder is silver-white gray powder, the gray decreases with the increase of particle size, and the gray increases with the decrease of particle size; while atomized aluminum powder is basically produced by nitrogen atomized aluminum powder production process.
So what process did it go through? Please listen to Xiaobian break down one by one. First, the aluminum is melted into liquid aluminum, and then the compressed nitrogen gas is atomized into liquid droplets through a chemical reaction, and then cooled to become metal powder. The aluminum powder with different particle size ranges is then screened and classified by a classification system. The divided spherical aluminum powder is released. This is also the technological production process of atomized aluminum powder.
Atomized aluminum powder is an important raw material for the production of aluminum silver paste, with extremely low moisture content, which can be stored for a long time. Less impurities, more than 98% active aluminum, containing a very small amount of iron, silicon, copper and water. The particle size of aluminum powder is relatively uniform, the distribution interval is narrow, and the tap density is high. It is widely used in metal pigments, military industry, aerospace, chemical industry, metallurgy, refractory materials, new building materials and anti-corrosion materials.
