Resin, grease, tar, rust, asphalt, paint oil, decals, ink, dirt, jet exhaust tars, soot and adhesives are some of the materials extracted by this method. Only the extracted material must be disposed of, as the dry ice sublimes into the air. Dry ice blasting employs the frosty temperature of dry ice “blasting” on the contaminant making it shrink and suspend its adhesion.
The process uses small particles of dry ice the size of a grain to shoot them out of the jet vent with compressed high-pressure air. The nozzle’s unusual structure can prompt the particles to expedite faster than the speed of sound before hitting the surface to be cleaned.
This cleaning process reduces personal contact with poisonous chemicals and is an environmentally benign cleaning course certified by the FDA, EPA, and USDA. Dry ice blasting can also displace environmentally hazardous resolvents safely and less costly.
