Dry Ice Blasting

详情

This exciting technology was first developed overseas and is now available in South Africa. The process requires a blast cleaning machine, fresh high quality 3mm dry ice pellets and a source of compressed air. 

The dry ice pellets are thrown into the hopper of the blast cleaning machine, the air hose connected and the pellets are then blasted out of the gun at super sonic speeds onto the substrate. The cleaning process works in 2 stages. Firstly the pellets that strike the substrate cool it down to a very low temperature (up to - *8°C), this makes the substrate hard and brittle. The second part of the process occurs due to the impact of the pellets against the cold brittle substrate. Their mass multiplied by their high velocity creates a powerful force that removes the brittle substrate leaving behind a clean surface.
