Process description
The dry-ice blasting equipment IC 022
operates with granules of dry-ice pellets
(
Ø
3mm),
produced
through
the
pressing of the CO
2
snow. The pellets
are blasted on the surface to be cleaned.
The dirt from the surface is frozen
through thermal shock and it breaks
because of the different expansion
coefficients. The CO
2
granulate sublimes
in the moment of impact from solid to
gaseous state. Only the initial dirt
remains behind.
The dry-ice pellets in the hopper
(
Ø
3mm) will be mixed using a
compressed air operated dosing system,
transported through the blasting hose
and accelerated through blasting nozzle,
the pellets can reach the speed of sound
(depending on compressed air pressure
and blasting nozzle).
