Silica Sand Blasting

What is silica sand blasting?

Abrasive blasting involves forcefully projecting a stream of abrasive particles onto a surface, usually with compressed air or steam. Because silica sand is commonly used in this process, Powder Coating in Ahmedabad workers who perform abrasive blasting are often known as sandblasters.

Sandblasting uses compressed air or water to bombard a surface with a high-velocity barrage of abrasive particles. Crystalline silicates have been used ubiquitously as an abrasive media in both architectural and industrial sandblasting for decades: in the removal of flaws or applied coatings; for the application of surface roughness and textures; and in the preservation of durable and historically-valuable stonework. However, silica-based blasting media have fallen out of favor for several reasons:

  • Crystalline silica is inefficient compared to novel engineered abrasives, requiring longer sandblasting periods and potentially multiple cycles to achieve the desired surface finish.
  • Silica-based blasting media degrades rapidly and cannot be recycled for multiple use cycles, representing a poor product service life and increased operating costs over time.
  • Free silica in sandblasting environments represent a significant health and safety risk for operating and incident personnel who may accidentally ingest free-flowing silica particles.
