Exploring The Basics of Blasting

What Is Blasting?

Blasting is used to describe the process of propelling small particles (either spherical or angled) at a high velocity towards the object being blasted. There are several different ways to ensure that these particles achieve a high velocity—air, water, or mechanics are utilized.

In airblasting, for example, an air compressor delivers a mixture of air and blasting media at high speeds and pressures. For operator safety, this procedure is usually processed in blasting rooms.

The Utility of Blasting

A variety of uses exist for blasting, including the removal of a substrate from some object or the preparation of parts for other factory functions. For example, blasting can remove:

  • Rust
  • Dirt
  • Paint
  • Corrosion

Alternatively, blasting can prepare parts for:

  • Assembly
  • Painting
  • Coating
  • Plating

Various Blasting Media

The types of particles, also called media, which are propelled by air towards the parts being processed can vary widely depending on the purpose of the blasting. For some jobs such as paint removal or rust removal, abrasive substances like sand are used. Less abrasive or nonabrasive media can be used for jobs where such a degree of roughness is not required—walnut shells and baking soda, for example, are used for milder tasks.

Safety Concerns

Occupational safety and health concerns vary depending on the blasting media utilized. Abrasive blasting, which often uses silica sand, poses a high risk to the lungs if inhaled. These considerations are important when new blasting rooms are installed. Without the proper training, education, and blasting equipment, operators are at risk of injury and health complications.

This is why Airblast AFC provides operator training after the installation of each blasting room. Not only does Airblast AFC take pride in the quality of work and construction during the installation process, but employees also strive to ensure the longterm safety of the room’s future operators by providing a thorough education and continued blasting room maintenance.
