Dry Ice blasting is comparable to sand blasting. Both use compressed air as kinetic energy, feeding particles into a high velocity air stream from a compressor, via a hose, through a jet nozzle (blasting gun) onto a surface. Dry Ice blasting does not compete with sandblasting. It has different properties. Sand Blasting is abrasive (corund, ash, steel shot, glass beads, powder, etc.) . Along with the contaminate it can remove surface material. It is therefore ideal to remove rust corrosion, which Dry Ice blasting will not. Sand blasting produces secondary waste, which requires disposal. Dry
Ice Blasting is not abrasive. It does not remove or harm substrates
(when performed by an experienced trained operator). Dry Ice Blasting
does not produce secondary waste. The Dry Ice sublimes to CO2
vapor on impact. Only the contaminates remain behind for disposal. |

Kinetic Energy from compressed air propels the Dry Ice particles up to sonic speeds. Though very light in weight, they puncture the contaminate and chip away at it, thereby opening the surface of the contaminate. On impact, solid CO2 absorbs energy and sublimes instantly to CO2 vapor. Thermal Differentials create an immediate and localized cold shock to the contaminate, which contracts at -78.50°C versus a substrate, which usually only cools down by up to 15°C to current temperature. This promotes a contact break between contaminate and substrate. It is particularly noticeable where hard resins have been applied to metal surfaces. Reverse Fracturing: As the Dry Ice sublimes on impact, it increases up to 540 times its volume from solid to vapor, when it enters the cracks within the contaminate. This gas expansion, breaking up the contaminate from within, is the major factor responsible for the Dry Ice cleaning effect. |

Dry Ice Blasting is a sensible alternative for many industrial cleaning applications. It allows cleaning of machinery on-site without harming surfaces, parts or components, and without interfering with electrical or electronic equipment (100% water-free!).
