5. Dry Ice Blasting CO 2 dry ice pellets are blasted out at sonic speed to capture unwanted contaminants Dry Ice is harder than concrete Rapid Sublimation of CO 2 Gas –Solid CO 2 expands 400-800 times its volume –At -110 o F there is a thermal shock effect –Rapidly expanding CO 2 gas creates a mini shock wave Foreign body freezes at a faster rate than host –Falls off –Loses adhesive properties
