THE DEVELOPMENT OF CARBON DIOXIDE BLASTING TECHNOLOGY IN NAVAL SHIPYARDS

Carbon dioxide blasting is a relatively new paint removal system that liquefies readily available carbon dioxide, solidifies it into pellets and then blasts the pellets toward the target using high velocity compressed air. Unlike the previously used slag abrasive method, this new blasting technique does away with hazardous slag wastes, irritating dust plumes and noxious water streams. The pellet blasting equipment has proven to be successful in both "thick- skinned" (ship paints) and "thin-skinned" (aircraft paints) coating removal. As the carbon dioxide pellets subseqently evaporate back into the environment, the cleaning technique is perfectly suitable for use in confined work spaces. After undergoing extensive application tests in various naval shipyards and aircraft facilities, the carbon dioxide blasting technique has gained wide acceptance as an environmentally safe and cost-effective paint removal system.
