Spray pretreatment is a crucial step in the coating production
line, where the surface of the workpiece undergoes a thorough
cleaning and preparation process before the actual coating
application. The goal of spray pretreatment is to enhance the
adhesion and durability of the applied coating, ensuring a
high-quality and long-lasting finish. There are various types of
spray pretreatment methods used in coating production lines, and
some of the common ones include: | Degreasing | In this step, a cleaning solution is sprayed onto the surface of
the workpiece to remove any grease, oil, or contaminants that may
be present. Degreasing is essential to ensure proper coating
adhesion. | | Phosphating | Phosphating is a chemical pretreatment process where a phosphate
solution is sprayed onto the workpiece's surface. It creates a
thin, adherent phosphate coating that improves the coating's
adhesion and corrosion resistance. | | Rinsing | After each pretreatment stage, the workpiece is typically rinsed
with water to remove any remaining cleaning or pretreatment
chemicals. | | Surface Conditioning | Some pretreatment systems may include a surface conditioning step,
where the workpiece is exposed to abrasive media to create a
roughened surface. This helps improve coating adhesion, especially
for certain materials. | | Drying | Before the actual coating process, the workpiece is often dried to
ensure a clean and moisture-free surface, which is vital for a
successful coating application. |
