With the method of sandblasting, particles are being projected onto the metallic surface to be cleaned (coper slag). As an outcome we have iron oxide rust removed and the surface fully cleaned.
The main advantage of sandlasting is that it makes the surfaced that has been applied onto rough, making this way the process of painting easy and of excellent quality(layers of paint are better attached on rough/harsh surfaces). All sandblasting and painting projects are carried out in compliance to INT´L STANDARDS
The Grit-Blasting used varies depends on the process treatment required.
Material selection is of paramount importance decision in the process of Grit-Blasting methods.The various material types have different characteristics namely, hardness, shape, and density, and each is available in a wide range of particle sizes.
Grit-Blasting is a crucial process used not only to remove rust, but to prepare surfaces for high performance coatings, high resistance (temperature) coatings etc.
The range of areas for Grit-Blasting include:
1. Surface preparation prior to painting, bonding or other coating operations.
2. Removal of rust, scale, sand, or paint from fabricated components.
3. Roughening of industrial gas turbine engine component surfaces in preparation for thermal spray coating.
4. Removal of burrs or edge profiling machined components.
5. Providing a matte cosmetic surface finish.
6. Removal of mold flash.
7. Surface texturing of tooling, and molds to alter the appearance of surface.
