Dry Ice Blasting : How it works ?
Dry Ice Blasting : Explanations
Cryoblaster® is a cleaning technique that uses dry ice and its physical properties as a means of instantaneous disbonding of pollution.
The dry ice having the hardness of the chalk, the treatment cleans the surfaces smoothly (see advantages of dry ice blasting).
The Cryoblaster® process uses dry ice projection using blasters (see products) and compressed air.
This process is based on the simultaneous action of 3 physical phenomena…
The dry ice in the form of pellets with a diameter of 3 mm is blasted at very high speed on surfaces to be treated thanks to compressed air and the use of supersonic nozzles (convergence/divergence).
During impact, pellets generate a localized shock wave that facilitates the decohesion of pollution on the treated surface.
The temperature of the dry ice pellets (-78,5 °c/-109,3 °F) creates a thermal micro-shock between the pollution and the surface, and facilitates the detachment of the latter. It’s the thermal differential.
The warmer the temperature of the surface to be treated, the more rapid the Cryoblaster® cryogenic cleaning process is (e.g., aluminum smelter gravity mould).
The impact of the dry ice, Sublime (transition from solid state to gas) in a ratio of 1 to 700.
The dirt is literally blown. The only thing left is to sweep or suck up the dirt. The treatment is dry and does not generate any secondary waste, contrary to the use of a high pressure cleaner or a sandblaster.
