ICE BLASTING FOR GENERAL MAINTENANCE
Cold Jet dry
ice blasting is capable of cleaning, without damage, most
industrial equipment, machinery, machine tools, curing presses,
and assembly line equipment.
Cold Jet dry
ice blasting can also clean on and around hydraulic
power units, and it can
be used to clean electrical power, control
and distribution components without
a thought, whereas high-pressure water blasting is known to cause
significant start up and downtime problems.
be dry ice blasted - without removing the paint - for aesthetics,
ease of maintenance, and to decrease its operating temperature,
which in turn can reduce downtime. Or, the same factory painted
equipment can be cleaned without paint removal in preparation for
(Screws) Often used to assist in mixing or to
create pressure behind dies. Dry ice blasting application difficulty
depends on the material being extruded, but the potential of cleaning
on-line and without chemicals makes it attractive to
There are many names and types of production
fixtures, but virtually any item that is part of a production process
and is difficult to clean on-line or during production hours by
traditional means may be an excellent Cold Jet dry ice blasting
application. Examples would be:
Carrying Fixtures (paint hooks): a
thick (1/4" to 3/4" - 0.64cm to 1.9cm) coating often forms from layers
of overspray. (This combination allows differing coefficients of expansion
to play a significant role in the removal process.)

- Hoppers -
the larger the device the better, since it is more difficult to
remove from the line and/or the plant to be cleaned by less expensive
means. Also, a paint hook may have critical
areas, such as electrostatic ground contact or product contact areas,
which, if cleaned often, will provide significant quality and production
Adhesives are easily removed by dry ice blasting
compared to alternative methods as the lowered temperature serves
to weaken the adhesive bond.
Abrasive methods often generate heat and can therefore fail
with some adhesive removal.
& polymers: Generally these
are similar to adhesives as far as the results of Cold Jet dry ice
blasting vs. alternative removal methods is concerned.
grease, petroleum: Cold
Jet dry ice blasting readily removes viscous
materials. There is, however, a potential for redeposition.
on an accessible flat surface may be removed at up to 20
sq. ft. (1.86 m2) per minute while heavier "pure"
grease may be limited to
approximately 4 sq. ft. (0.37 m2) per minute.
That being said, grease that is being removed from a surface
is seldom "pure." Generally, it has been mixed with dust and production
debris and further "cured' by friction and/or heat. Removal
of this "impure" material
may be in the range of 1 sq. ft. (0.09 m2)
Asphalt tar and related materials tend to
contract and loose their bond quickly, particularly when on a smooth
surface. In some
cases tar maybe removed faster that grease.

deburring, etching, and "SOFT PARTS" cutting:
Plastic parts requiring trimming may be trimmed
with the Cold Jet dry ice blasting process, rather than with extensive
Jet dry ice blasting removes algae, sea slime, and mussels better
than water blasting, as water blasting
removes only 80%, allowing for the organic matter to reattach. Examples:
- Ship Hulls
- Sea Water
- Engine Room,
Mechanical and Electrical Equipment
waste reduction and disposal can be considered an industrial classification.
Since dry ice sublimates, the volume of
hazardous materials (and their related disposal cost) does not increase
with dry ice blast cleaning as it does with grit blasting, water
blasting, or chemical methods. This is particularly important
to nuclear decontamination because the grit used to clean radioactive
items becomes contaminated as well and is then much more expensive
to dispose of.
When dry ice
blast cleaning replaces hazardous chemical cleaners
the disposal cost for those chemicals is eliminated. Furthermore,
decontamination is often performed in a containment chamber, in
which airborne contamination is collected
by H.E.P.A. filters. Examples:
- PCB Contamination
- Heavy Metals
- Removal of
Radioactive Surface Contamination
Jet dry ice blasting is extremely effective in removing toxic residues,
soot, and associated smells after a fire.
