Method for manufacturing mixed powder coatings

Method for Manufacturing Mixed Powder Coatings Using Brightness/Chroma Classification and Virgin Powder Blending

This technology involves classifying waste powder coatings based on color, brightness, and chroma, followed by melting, extruding, and pulverizing them to create recycled coatings, which are then blended with virgin coatings to adjust the gloss.

Because waste powder coatings vary in color and gloss, direct reuse often results in inconsistent quality, making it difficult to produce recycled coatings with controlled color and gloss properties.

By classifying materials based on brightness and chroma and blending them with virgin coatings to control color and gloss, this technology enables the production of high-quality, uniform mixed powder coatings.

Key Features:

• Color classification step: Separating waste powder coatings, removing impurities, and sorting them by color.
• Brightness classification step: Sorting color-classified waste powder coatings into specific intervals ranging from white to black.
• Chroma classification step: Sorting brightness-classified waste powder coatings into specific intervals based on chroma.
• Mixed powder coating manufacturing step: Melting, extruding, and pulverizing the classified waste powder coatings to create recycled material, then blending it with virgin powder coatings.
