What is Dry Ice Blasting?
5/8/2020 (Permalink)
Dry ice blasting is a revolutionary blasting method that uses dry ice pellets (CO2 in solid form) as the blasting material. The process is very environmentally friendly and provides a fast and effective alternative to traditional methods of cleaning industrial production equipment.
Dry Ice Blasting Is A Three-Step Process
1. Kinetic - When dry ice pellets are accelerated in a jet of compressed air and strike a surface at the speed of sound, they crack and loosen the coating of the surface being treated.
2. Thermal - The low temperature of dry ice pellets (-79C/-110F) makes the coating brittle, cracks it and loosens it. This allows dry ice to permeate the coating.
3. Sublimation - Dry ice penetrates the coating and immediately sublimes (passes directly from solid to vapor state). This results in a 700-fold increase in volume, an explosive effect that lifts the coating off the surface.
