What is Dry Ice Blasting? What is it, exactly?

Blasting using dry ice consists of the following steps:

  • the use of solid CO2 (carbon dioxide) pellets accelerated by compressed air to clean or remove undesired contaminants from industrial equipment, machinery, buildings, and flooring. When these solid pellets hit the surface, they rapidly expand into a gaseous condition hundreds of times their initial solid volume, causing small explosions on the area to be cleaned. Dry ice has a temperature of -109 degrees Fahrenheit, which facilitates in the removal of numerous materials.
  • regulated by varying the air pressure and pellet amount utilised Heavy layers of coatings, paint, resins, mould release, plastic, residue build-up, adhesives, and other materials can be readily removed this way. On the delicate side, a deflector plate at the nozzle allows the pellets to turn to powder on impact, allowing even circuit boards to be cleaned.
  • a significant advantage in terms of asset protection. Abrasive media blasting, rotary sanding discs, abrasive pads, scrapers, and other methods that remove metal and require expensive tooling replacement are no longer necessary. If the surface was previously polished, it will remain so when the blasting is completed. No metal is removed during the blasting process, increasing the life of the equipment and tooling.
  • Because it is non-abrasive, no masking of glass, bearings, or moving metal parts is necessary. Many types of machinery may now be cleaned in place and on the go, obviating the requirement for maintenance shutdowns. More production time means less downtime.
  • it’s both safe and eco-friendly. Dry ice is pure CO2 in its solid state; CO2 is present in the air around us in its gaseous state. Our bodies consume oxygen when we breath and exhale CO2. Green plants absorb CO2 from the atmosphere and release oxygen.
  • non-toxic, non-conductive, and no dangerous cleaning chemicals or solutions are exposed to employees. The USDA, EPA, and FDA have all approved dry ice blasting.

Dry ice blasting lowers disposal expenses significantly. Cleaning solvents, blast media, rags, absorbent pads, and other secondary waste streams produced by traditional industrial cleaning procedures are frequently polluted with dangerous chemicals or materials, necessitating special treatment and incurring high disposal costs. There is no secondary waste stream as a result of this technique.
