How Does Dry Ice Blasting Process Work?
The Dry Ice Blasting process uses pellets are made through a process of taking Liquid Carbon Dioxide (CO2) and expanding it to produce a snow like substance, that is compressed through a die to make hard Dry Ice Pellets.
Dry Ice Pellets are then propelled at a supersonic speed by a compressed air gun (similar to other blasting systems). Upon impact, the dry ice creates a micro-thermal shock (caused by the extreme cold temperature of -79º C) which breaks the bond between the coating and the substrate. The high pressure air stream removes the dirt from the surface, while the dry ice pellets vaporize (sublimate) before your eyes.
