How Does Dry Ice Blasting Work?
Dry ice blasting has three dimensions contributing to its effectiveness. First, there is a thermal impact. At a temperature of -109ºF, dry ice causes thermal shock of the surface due to the difference in temperature. This causes the bond between the contaminant and the surface to break leaving a clean surface behind. Second, there is kinetic impact, as the dry ice pellets bombard the surface. Third, as sublimation of the dry ice takes place, it expands in volume 800%, propelling the contaminant off the surface.
