Sandstrålning

Sandstrålning, also known as sandblasting, is a process used to clean, shape, or finish surfaces by forcefully propelling a stream of abrasive material against the target surface. The abrasive material is typically small particles of sand, glass beads, or other media. Sandstrålning is commonly used in various industries, including manufacturing, automotive, aerospace, and construction, to remove rust, paint, or other contaminants, as well as to prepare surfaces for coating or welding.

The process involves several key components: the abrasive material, the pressure source, and the nozzle or gun. The abrasive material is fed into a chamber where it is mixed with compressed air or another propellant. The mixture is then directed through a nozzle or gun, creating a high-velocity stream that impacts the target surface. The force of the impact dislodges contaminants and roughens the surface, improving adhesion for subsequent coatings or treatments.

Sandstrålning offers several advantages, including its ability to clean hard-to-reach areas, its versatility in handling various materials, and its relatively low cost compared to other surface preparation methods. However, it also has some limitations, such as the potential for environmental impact due to the release of abrasive particles and the need for proper safety measures to protect operators from the high-velocity stream.

In summary, sandstrålning is a widely used industrial process for surface preparation and finishing. Its effectiveness, versatility, and relatively low cost make it a valuable tool in many applications. However, it is essential to consider the environmental and safety implications when using this method.
