What types of surface treatment processes are there for power lithium-ion battery aluminum shells? -Lithium - Ion Battery Equipment
1. Powder electrostatic spraying process:
The working principle of the powder electrostatic spraying process is almost identical to the general electrostatic spraying method of liquid paint. The difference is that the powder spraying is dispersed rather than atomized. It is a coating sprayed by an electrostatic powder spray gun. The powder particles are negatively charged while being dispersed. The charged powder particles are affected by airflow and electrostatic attraction and are applied to the grounded power lithium-ion battery aluminum shell and then heated. Melt and solidify to form a film.(Lithium - Ion Battery Equipment)
2. Electrophoretic painting process:
The electrophoretic painting process is a coating method that uses an external electric field to cause the particles such as pigments and resins suspended in the electrophoretic fluid to migrate in a direction and deposit them on the surface of the substrate of one of the electrodes. It is water-soluble, non-toxic, and easy to control automatically. After the electrophoretic painting process, the surface of the power lithium-ion battery aluminum shell has a soft luster and can resist the invasion of cement and mortar acid rain.
3. Electrochemical surface ceramicization process:
The aluminum shell of the power lithium-ion battery pack uses a plasma-enhanced electrochemical surface ceramicization process. Although the quality is excellent, the cost is high. The profiles produced by this process have more than 20 colors. Its biggest feature is that it can be colored like printed cloth. The surface of the profiles is colorful and the decoration effect is the best.
4. Frosting process:
Frosted aluminum profiles avoid the shortcomings of bright aluminum alloy profiles that may cause light interference under certain circumstances and conditions in architectural decoration. Its surface is as delicate and soft as brocade, and is very popular in the market. However, the existing frosted aluminum profiles The material must overcome uneven surface sand and be able to see deficiencies in the mold pattern.
