Surface Preparation Methods and Equipment
Surface Preparation Methods and Equipment
Welcome back to our powder coating series, presented by COATECH Powder Coatings. Today, we delve into the methods and equipment used for surface preparation, a critical step in achieving a flawless powder coating finish.
Mechanical Methods
- Abrasive Blasting: This method involves propelling abrasive materials at high velocity against the surface to remove contaminants and create a profile for better coating adhesion. Common abrasives include sand, steel grit, and aluminum oxide.
- Grinding and Sanding: Handheld or automated tools equipped with abrasive discs or belts are used to clean and smooth surfaces, particularly for small areas or intricate parts.
Chemical Methods
- Chemical Cleaning: This process uses solvents or alkaline solutions to dissolve and remove oils, greases, and other organic contaminants. It’s often used as a preliminary step before mechanical cleaning.
- Acid Etching: Acid solutions are applied to remove oxides and create a reactive surface. It’s particularly effective for preparing metals like steel and aluminum.
Equipment for Surface Preparation
- Blast Cabinets and Rooms: Enclosed spaces where abrasive blasting is performed. They contain the abrasive material and dust, ensuring a clean and safe working environment.
- Dip Tanks and Spray Systems: Used for chemical cleaning and etching, these systems immerse or spray parts with cleaning solutions to ensure thorough surface preparation.
- Drying Ovens: After cleaning and rinsing, parts need to be dried completely to prevent defects in the powder coating. Drying ovens ensure parts are moisture-free before coating application
