Pulbervärvimise

Pulbervärvimine is a surface finishing technique that applies a protective and decorative coating to metal objects. The process involves spraying a dry powder, typically made of finely ground pigment and resin, onto the surface of the substrate. This powder is electrostatically charged, causing it to adhere to the electrically grounded object. Once applied, the coated object is cured in an oven at a specific temperature. During curing, the powder melts, flows together, and forms a smooth, durable, and continuous film.

This method offers several advantages over traditional liquid painting. Pulbervärvimine produces a thicker and more robust coating that is highly resistant to chipping, scratching, and fading. It is also environmentally friendly, as it contains no volatile organic compounds (VOCs) and overspray can often be reclaimed and reused. The finish achieved is typically more uniform and aesthetically pleasing, with a wide range of colors, textures, and gloss levels available.

The application of pulbervärvimine is versatile and can be used on a variety of metal items, including automotive parts, furniture, appliances, architectural elements, and industrial equipment. The pretreatment of the metal surface is a crucial step to ensure proper adhesion and corrosion resistance. This usually involves cleaning and sometimes phosphating the metal. The process is efficient, with relatively short curing times, making it a cost-effective solution for many manufacturing and repair applications.
