Dry Ice blasting

white brush style sydney

It can exist in our atmosphere for a short period of time as a solid with a temperature of -78.6 deg C whilst it slowly changes into a large volume of CO2 gas. Technically, this is called sublimation.

 

If small particles of dry ice are blasted at high speed on to a contaminated surface the impact energy will rapidly increases the state change from solid to gas, so as the small particles lodge themselves within the pores of the contamination large volumes of CO2 gas will be generated, which will break up the contaminant that will then be blown away by the driving force of the blast, typically compressed air.

 

Dry ice has a similar hardness to plaster so it does not clean abrasively. Contaminant can be removed from polished metal surfaces without affecting the surface finish as there is always a gas cushion between the dry ice and the substrate.
