hiekkapuhdistuksella

Hiekkapuhdistus is a Finnish term referring to sandblasting, a surface treatment process. It involves propelling abrasive material, typically sand, at high velocity against a surface to clean, roughen, or shape it. The abrasive particles impact the surface, removing unwanted material such as paint, rust, dirt, or scale. This process is highly effective for preparing surfaces for further treatment, like painting or coating, by creating a clean and slightly roughened profile for better adhesion.

The equipment used for hiekkapuhdistus consists of a compressor to generate compressed air, a hose to deliver the air and abrasive mixture, and a nozzle to direct the stream. Various abrasive materials can be used, including sand, glass beads, walnut shells, or even dry ice, depending on the substrate and the desired outcome. The choice of abrasive and pressure is crucial to avoid damaging the underlying material.

Hiekkapuhdistus is employed in numerous industries. In construction, it is used for cleaning building facades, bridges, and concrete structures. In automotive repair, it effectively removes rust and old paint from car bodies. It is also utilized in metal fabrication for preparing surfaces before welding or coating, and in the maritime industry for cleaning ship hulls. While effective, hiekkapuhdistus requires safety precautions due to the airborne abrasive particles and potential for noise, including respiratory protection and eye protection for operators.
