What are the types of surface solutions for aluminum shells of power lithium-ion batteries? 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 a paint sprayed by an electrostatic powder spray gun, which makes the powder particles negatively charged while dispersing. The charged powder particles are applied to the grounded power lithium-ion battery aluminum shell for the purpose of airflow and electrostatic attraction, and then heated Melt and solidify to form 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 ion 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 battery pack aluminum shell adopts plasma-enhanced electrochemical surface ceramization process. Although the quality is good, the cost is relatively high. The profiles produced by this process have more than 20 shades, 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 dressing effect is the best. 4. Frosted process: The frosted aluminum profile is guarded against the bright aluminum alloy profile. In the architectural decoration, there is a shortcoming of light interference under certain circumstances and conditions. Its surface is as delicate and soft as brocade, and it is very popular in the market. However, the existing frosted materials have to overcome the uneven surface sand and can see the lack of pattern patterns.
