is dry ice blast cleaning?
It is a process in which dry ice (solid C02) pellets are propelled
at supersonic speed, to impact the surface that is to be cleaned
or prepared. The pellets are accelerated by a stream of compressed
air in a controlled manner through a blasting machine, just as
with other traditional blasting systems (sand, bead, soda, solvent
and other blasting). The unique feature of dry ice is its ability
to vaporize upon impact leaving no secondary waste.
This process is very environment friendly and provides a fast
and effective alternative to traditional methods of cleaning industrial
production / process equipment, Tooling and components.
What is dry ice and how dry ice pellets are prepared?
Solid C02 is commonly referred to as Dry Ice. It is produced by
allowing liquid C02 to expand to atmospheric pressure which forms
dry ice snow. This snow is then compressed and extruded through
dies to form pellets and nuggets. At atmospheric pressure, the
temperature of dry ice is -78.5�C.
