Analysis of Surface Treatment Process Types of Power Lithium Battery Aluminum Shell

1. Powder electrostatic spraying process: The working principle of powder electrostatic spraying process is almost the same as that of ordinary liquid coating electrostatic spraying method. The difference is that powder spraying is dispersed instead of atomized. It is the paint sprayed by the electrostatic powder spray gun, which makes the powder particles negatively charged while being dispersed. The charged powder particles are applied to the grounded power lithium battery aluminum shell for the purpose of airflow and electrostatic attraction, and then heated and melted. Cured into a film. 2. Electrophoresis painting process: The electrophoresis painting process is a coating method that uses an external electric field to make particles such as pigments and resins suspended in the electrophoresis liquid migrate and deposit on the surface of one of the electrodes. It has the characteristics of water solubility, non-toxicity, and easy automatic control. The aluminum shell of the power lithium battery after the electrophoretic painting process has a soft surface gloss and can resist the invasion of cement and mortar acid rain. 3. Electrochemical surface ceramization process: The power lithium ion battery pack aluminum shell adopts plasma-enhanced electrochemical surface ceramization process. Although the quality is good, the cost is higher. The profiles produced by this process have more than 20 tones, and the biggest feature is that they can be colored according to the same color as the printed cloth. The surface of the profile is colorful and the decoration effect is the best. 4. Frosted process: Frosted aluminum profile prevents the bright aluminum profile from causing light interference in architectural decoration under certain environment and conditions. Its surface is as delicate and soft as brocade, which is very popular in the market. However, the existing frosted materials must overcome the uneven surface sand grains, and the lack of pattern patterns can be seen.
