DRY-ICE BLASTING
Dry-Ice Blasting Is Suitable for Sensitive Surfaces
Dry-ice blasting, also known as dry-ice cleaning, is a chemical-free and waterless cleaning method that is particularly well suited for sensitive surfaces and for applications where water cannot be used. Dry-ice blasting was originally developed in the United States for the needs of the aviation industry and has since gained recognition across many industries and a wide range of applications.
Dry-ice blasting is at its best in specialized sites that are difficult to clean or where cleaning would otherwise be impossible. In industrial environments, such applications include production lines and electrical cabinets.
Dry-Ice Blasting Removes Dirt Without Water, Abrasion or Chemicals
Like other blasting techniques, dry-ice blasting utilizes pressurized air. However, instead of relying on abrasion, its cleaning effect is based on the sublimation of dry ice and the resulting thermal reaction.
Compressed air propels dry ice pellets (solid carbon dioxide) onto the surface being cleaned. Upon contact with the warmer surface, the pellets instantly sublimate into gaseous carbon dioxide, creating a thermal shock reaction and microscopic pressure waves that work together to loosen and remove contaminants. Due to the speed of this reaction, the method is gentle on the underlying surface.
Because dry-ice blasting relies solely on carbon dioxide, no harmful chemicals are left behind, and the only waste left to clean up is the dislodged dirt.
