Industrial Dry Ice Blasting

Dry Ice Blasting is similar to sand blasting where a medium is accelerated in a pressurized air stream to impact a surface to be cleaned.  However, instead of using hard abrasive media to grind on and possibly damage a surface, dry ice blasting uses soft dry ice pellets at a temperature of -109.3°F.  The "blasting" of the dry ice against the material to be removed causes it to shrink and lost adhesion from its sub surface. When some of the dry ice penetrates through the material to be removed, it comes into contact with the underlying surface. The warmer sub-surface causes the dry ice to convert back into carbon dioxide gas. The gas has 800 times greater volume and expands behind the material, speeding up its removal. Some of the materials removed by this procedure include paint, oil, grease, asphalt, tar, decals, soot, dirt, ink resins and ahdesives. Only the removed material must be disposed of as the dry ice sublimes into the atmosphere.

Applications

Adhesives are easily removed in comparison to alternative methods as the lowered temperature serves to weaken the
adhesive bond.

Dry ice cleaning is extremely effective in fire remediation. Toxic residues, soot and associated smells dissipate quickly when cleaned using this method.

Food and Hospital institutions use dry ice cleaning on the surface of products and instruments because it is non-toxic and stops the growth of mold, mildew and other fungi as well as stopping odors by elimination of the bacterial host environment, not as a masking agend or cover-up.  Dry ice cleaning is 100% ecologically safe, USDA rated, biodegradable and harmless to humans, animals and marine life.
