2. Powder Coating Technology
2.1 Ndui funcionamiento
Powder coating is a surface treatment technology that adheres dry powder coatings to the workpiece surface through electrostatic adsorption or fluidized bed technology, followed by heating to cure and form a coating. The basic principle is that the powder coating is charged under electrostatic action, adheres to the grounded workpiece surface, and then melts, levels, and cures through heating to form a uniform coating.
2.2 Flujo proceso
The process flow of powder coating typically includes the following steps:
- Pretratamiento: Mfa̲ts'i 'bu̲i desengrasante, Desoxidación, ne fosfatado pa garantizar da superficie ar pieza ar 'be̲fi ntsuni 'Beni ne pets'i ar hño adherencia.
- Powder Coating: The powder coating is evenly sprayed onto the workpiece surface using an electrostatic spray gun or fluidized bed.
- Curado: The coated workpiece is placed in an oven, where the powder coating melts, levels, and cures under heat.
- Cooling: The cured workpiece is cooled to form a durable film.
2.3 Ventajas
