This is a photo comparing the visual changes before and after the blasting process.
This photo shows the blasting process. When comparing before and after the processing, the change in appearance is very clearly noticeable.
This product was completely black due to the presence of mill scale (black skin) on the surface before processing. However, by using a technique called blasting for surface preparation, we were able to remove the mill scale from the surface and expose the material itself. Blasting is a technique that removes impurities attached to the surface by spraying high-pressure air or water. Steel changes to a silvery color in this way. By removing impurities such as mill scale and rust from the surface and applying paint, the adhesion of the paint improves, and the lifespan of the paint film is extended. It also helps prevent defects and deterioration in painting due to insufficient surface cleanliness. If the paint does not adhere properly, the paint film may peel off or discolor. Surface impurities are a major enemy to painting and are a crucial factor that affects the lifespan of the paint. If painting is done without surface preparation, impurities will remain under the paint film, accelerating its deterioration. Currently, the SDGs (Sustainable Development Goals) have become a global objective, and we aim to extend the lifespan of products by combining blasting and painting to utilize resources more effectively. By extending the lifespan, we can reduce the frequency of product replacements, leading to resource conservation.
