3003 3005 xem da bong truc tiep coil surface treatment for power battery shell
The four major processes for surface treatment of new energy battery xem da bong truc tiep shells include powder electrostatic spraying, electrophoretic painting, plasma-enhanced electrochemical surface ceramization and frosting.
Powder electrostatic spraying:use an electrostatic powder spray gun to spray negatively charged powder onto the xem da bong truc tiep case of the power battery, and then heat, melt and solidify to form a film. This process can provide good corrosion resistance and acid, alkali and salt spray resistance.
Electrophoretic painting:a coating method in which pigments and resin particles suspended in electrophoretic fluid are oriented to migrate and deposited on the surface of the xem da bong truc tiep shell of the power battery by using an external electric field. After electrophoretic painting, the surface of the xem da bong truc tiep shell has a soft luster, which can resist the erosion of cement, mortar and acid rain.
Plasma-enhanced electrochemical surface ceramization:the plasma-enhanced electrochemical surface ceramization process is used to improve performance by forming a ceramic film on the surface of the xem da bong truc tiep shell. This process can produce a variety of shades, and the decorative effect is good, but the cost is relatively high.
Sanding process:use chemical sanding agent to chemically treat the surface of the xem da bong truc tiep shell to obtain a beautiful sanding effect on the surface. This method produces the same sand finish as mechanical sandblasting and is suitable for thin or small pieces of xem da bong truc tiep casings.
