The Process …. In a nutshell
In principle, dry ice blasting is similar to other forms of shot blasting such as sand or grit blasting.
The main difference is that the medium differs (Co2) and that much more control can be used with the correct use of the size of pellet, the airflow and also the nozzle used for specific applications.
Where normal shot blasting would use a ‘chisel’ effect to remove the contaminant, DIB used the process called reverse fracturing or thermal shock.
The -79C of the dry ice instantly freezes the contaminant and breaks the bond between the contaminant and the substrate and lifts it away…more like a ‘spatula’ effect.
