"sandblasting"的定义和意义

What is "sandblasting"?

Sandblasting is a process used to clean or etch the surface of a material by blasting it with high-speed particles, usually sand or another abrasive material. The force of the particles hitting the surface removes dirt, rust, paint, or creates patterns and textures on materials like metal, glass, wood, or stone. Sandblasting is commonly used in industrial settings for cleaning or preparing surfaces before painting, as well as in artistic applications to carve designs into glass or stone.
