By performing blast treatment, the adhesion of the paint is greatly improved, resulting in a beautiful appearance.
Blasting processing is a type of "substrate adjustment" that involves simultaneously spraying compressed air and abrasives to collide the material and abrasives at high speed. The abrasives that collide at high speed scrape away the surface of the material, exposing it. The surface of untreated materials often has a lot of oxidation films (mill scale), rust, and impurities attached to it. If these impurities are not removed, the paint will quickly peel off. Careful substrate adjustment can prevent painting defects before they occur. Blasting does not use chemicals, and there are many types of abrasives available, making it a significant advantage as it can process various materials without restriction. Additionally, it is very effective not only for painting but also as a pre-treatment for plating, lining, and coating. The countless bumps and indentations created by the impact of the abrasives increase the contact area, allowing for the 'anchor effect' where the material penetrates into the gaps and hardens. This effect significantly enhances adhesion, resulting in a more beautiful finish for the paint. With no impurities and a strongly adhered paint, it is said that the anti-corrosion effect lasts 3 to 4 times longer compared to regular painting. This allows for a reduction in the frequency of repainting, repairs, and maintenance, extending intervals and thus conserving resources and costs.

basic information
◎Surface preparation This refers to the process of making the substrate more suitable for painting. Surface preparation involves removing rust, dirt, and deteriorated paint films from the substrate, and the resulting surface irregularities significantly improve the adhesion of the paint. The causes that affect the lifespan of the paint account for about 50% due to surface preparation, making it a crucial process. 【Impact/Causes on Paint Film Lifespan】 https://www.nc-net.or.jp/company/98405/product/detail/179473 ◎Mill scale Also known as black scale, it is an oxidized film that forms on the surface of steel during its production. In the manufacturing process of hot rolling, the metal is heated to high temperatures, causing it to combine with oxygen in the atmosphere and form black scale. Even when painting, black scale generally has poor adhesion, so it is common to remove it. 【List of Typical Painting Defects: Causes and Countermeasures】 https://www.nc-net.or.jp/company/98405/product/detail/192232/
