PRODUCTS HANDLING AREA
Electrophoretic painting is an organic polymer that is made to adhere to the surface of the product under a medium voltage (about 250~350V) and a relatively high current (800~1000A). The electrophoretic painting has a very good anti-corrosion effect and is the first of several coats applied to the product. In the ED painting process, the product is immersed in even the most nooks and crannies. Just like the electroplating process, the paint solution is the electrophoresis solution and the product is the cathode of that plating process.
Advantage:
– Create a paint film that penetrates deep into the recesses and nooks of the product to protect the product against rust.
– Better conversion of efficiency, up to 95% reduction in paint loss during work, especially when compared to spray method.
– As a water-based paint, it reduces the risk of fire, explosion, and environmental pollution during transportation as well as production. And, of course, reduce the cost of installing fire protection systems and waste treatment.
– Low viscosity of the solution (equivalent to water), easy to pump and operate as well as the ability to quickly exit the vehicle after dipping.
– The paint film after forming cannot be dissolved in water, allowing washing and recovering the amount of paint clinging to the car.
– This paint is dry enough to allow touching when transported to the baking oven.
– Unlike spraying paint, this powder coating will not sag while drying.
– This process is completely automated, reducing direct labor costs for enterprises.
Disadvantage:
Although the advantages of the electrophoretic painting process completely outweigh its disadvantages, some limitations still exist. electrophoretic painting is only possible on materials that are electrically conductive. Once a part has been coated, a second coat of electrophoresis is not possible. Therefore, the electrophoretic painting is only used for the first primer layer, the subsequent color coatings will use other technological methods.
