Will sandblasting spray sand onto the surface of parts?

1. Sand is not sprayed into the surface of the part, but used to cut the surface to obtain the required surface roughness.

2. Sandblasting is a process of cleaning and roughening the substrate surface through the impact of high-speed sand flow. Using compressed air as power, a high-speed jet beam is formed, and the spraying material is sprayed to the surface of the workpiece to be treated at high speed. Due to the impact and cutting action of sand on the surface of the workpiece, the surface of the workpiece has a certain cleanliness and different roughness, which improves the mechanical properties of the surface of the workpiece, thus improving the fatigue resistance of the workpiece, increasing the adhesion between the workpiece and the coating, prolonging the durability of the coating, and being beneficial to the leveling and decoration of the coating.
