Painting - powder coating
In the middle of 2007 we built a powder coating plant in our Halenkov plant. Powder coating is a modern technology of metal surface treatment. It meets strict criteria for environmental protection. It guarantees quality surface treatment of metals with powder paints. Part of the material preparation before powder coating is the thorough degreasing of the material surface, which is carried out in the degreasing machine W2005.3. For degreasing we use a water solution with the additive DURIDINE 3803 it, heated to a temperature of 50-55 °C. At the same time, the degreasing agent forms a protective layer on the surface consisting of ferric phosphate with a thickness of several tenths of a micron. The phosphate layer is firmly embedded in the surface of the material and significantly improves the adhesion of the paint. After degreasing is completed, a double rinse with cold water is carried out, followed by drying of the surface of the material.
Today, virtually all powder coatings are applied by spraying in an electrostatic field. This causes the powder particles to become electrically charged while the object being painted is grounded. The resulting electrostatic attraction is sufficient to form a sufficient layer of powder on the object, holding the dry powder in place until it melts and adheres to the surface in the 180°C firing oven. We have 3x MAJKA 1629 coating booths (1820 x 1960 x 1400 mm - width x height x depth) and 2x H+V Grygov baking ovens.
We use two basic methods to "charge" the powder:
- electrostatic charging
- tribostatic (kinetic) charging
In addition to overcoating, we are also able to wet-coat.
In case of other customer requirements we provide surface treatment, namely:
- cataphoresis painting
- heat treatments
- hot-dip galvanizing
Is that exactly what you need?
