What is an electrostatic powder coating?

In production, the electrostatic powder is a layer of the finishing process, during which dry powder is applied to the metal. By applying the electric charge to the color particles, as they are used, manufacturers can create a permanent and high -quality surface. The electrostatic powder coating, which dates back to the sixties, remains one of the most common processes of powder coating today. It creates a surface similar to the wet color, but offers a number of advantages in terms of quality and environmental problems.

Manufacturers can apply electrostatic powder to many product types. This type of surface treatment is primarily used on metals from steel to aluminum. It is also used to complete various consumer goods, from wire shelves to lawn. The electrostatic powder is also used on cars and other vehicles and remains a popular method of completing the external metal cladding.

This product may contain different materials depending on the product and manufacturer. Many of them include an epoxy resinItem base, although some rely on a hybrid mixture based on polyester. While polyester reduces the risk of yellowing on the surface coated with powder, it also offers less corrosion resistance. Acrylic products are used to create high -gloss electrostatic powder, while the enamel -based version is commonly used to complete electronic and mechanical equipment.

To apply electrostatic powder, users use a compressed air gun. When it enters the air, the weapon applies an electric charge to each color particle. This charge causes the particles to attract the surface of the metal. One particle has joined the metal, the object is heated until the color particle is dropped or moves to the surface.

This process offers a number of advantages over other types of finishing processes. Unlike wet color, dry colors no longer harsh solvents. This reduces the risk of healthcareH problems for users and for those who work nearby. Powder coating also facilitates the capture of unused particles of color that is lost during the spraying of wet color. These particles can then be re -used for future projects.

However, the electrostatic powder coating has its limitations. Although it can be used on most metals, it is not an effective method of completing the thermoplasty. When using an electrostatic powder coating, it may also be difficult to control the color thickness and the quality of the completion. Stronger coats can be relatively easy to use while thinner coats tend to be more difficult.
