Cryogenic cleaning (dry-ice blasting) is a process that involves projecting small particles of dry ice that are around 3 mm in diameter super fast by using a jet of compressed air. Dry ice is made of carbon dioxide (CO2) that once cooled to -78°C and compressed turns into a solid form. Its effectiveness is derived from the three chemical reactions that simultaneously occur during cleaning:
- Kinetic energy: the impact of dry ice particles that are being projected at high speed by the jet of compressed air.
- Thermal shock: the thermal effect created by dry ice particles that create a tension between the residue and the surface being cleaned.
- Sublimation: the rapid expansion of dry ice particles, which upon contact with the surface become 800 times larger, creating micro-explosions.
When it comes to decontaminating, dry-ice blasting gets into all the nooks and crannies that other methods can’t reach. It’s a quick, safe, non-toxic solution that’s very effective. Its semi-abrasive power allows us to remove contaminants from semi-porous surfaces like wood, brick and concrete without damaging their strength. It can thus be used in areas where other methods can’t. Furthermore, dry-ice blasting can be used indoors and outdoors because it respects environmental standards.
