What is Dry Ice Blasting?
Dry Ice Blasting is one of the most effective means of removing
loose surface and tightly bonded contaminants. The process itself
is similar to sandblasting, but provides an environmentally friendly,
non-conductive, non abrasive and most importantly, a non-waste
generating cleaning action.
How
does it work?
Dry Ice pellets are propelled via compressed air towards the contaminated
surface. The pellets hit the surface creating a micro-thermal
shock, cracking and delaminating of the substrate then occurs.
The dry ice pellets explode on impact, and as the pellet warms
it converts to a harmless CO2 gas which expands rapidly underneath
the substrate's surface. This forces the contaminant off from
behind, where it then typically falls to the ground. The remaining
dry ice sublimates into the air, with only the contaminant left
for disposal.
