Kinetic energy is transferred by the accelerated dry ice pellet as it hits the surface during the dry ice blasting process. The dry ice pellet sublimates (changes from solid to gas) upon impact and is softer compared to other cleaning media such as sand, grit, or beads. Dry ice blasting is non-abrasive and will not damage most substrate materials or affect tool tolerances.
Thermal-Shock Effect occurs when cold dry ice pellets (109 degrees Fahrenheit below zero) strike a much warmer, contaminated surface during dry ice blasting. The extremely cold temperature of the dry ice causes the bond to weaken between the surface being cleaned and dirt, grime, and other residues. This effect aids in the release of the contaminant when it is struck by the dry ice pellets during dry ice blasting.
Thermal-Kinetic Effect combines the impact of sublimation and the rapid heat transfer discussed above. During dry ice blasting, when the dry ice pellet hits the contaminated surface, the vapor expands so much (up to 800 times the volume of the pellet) and so fast that a micro-explosion occurs, taking off dirt and grime in the dry ice blasting process.
