International Classification:

B08B 7/00

US Classification:

134 7

Abstract:

Metal surfaces may be cleaned using a dry ice (CO) blasting processes. Once cleaned, the surfaces are ready to be painted. The process of this invention is especially useful on ships where there are numerous metal surfaces that are subject to dirt and corrosions. The proper operating parameters for each of the types of metal surfaces require exacting conditions. These parameters include the size of the dry ice pellets, the discharge rate of the ice pellets, the type of nozzle being used and the flow rate of the pellets, the pressure of the pellets leaving the nozzle. The dry ice cleaning processes of the present invention eliminates secondary waste streams and moisture, leaving the treated surfaces immediately ready for painting. Only the dirt, loose paint, debris and other surface contaminants removed during the dry ice cleaning process need to be cleaned up prior to preservation and/or painting and return to service.

US Classification:

228205

Abstract:

Metal surfaces that join together such as welded joints of foundations, hatches, railings, stanchions, decks, bulkheads and the like, crack, rust and corrode, occasionally to the point of failure, requiring repairs to be accomplished by welding. Before repair welding, the metal surfaces must be cleaned and may be cleaned using the dry ice (CO) blasting process of the present invention. The dry ice cleaning process of the present invention eliminates secondary environmentally hazardous waste streams and moisture, leaving the cleaned metal surfaces dry and immediately prepared for welding operations and/or preservation having removed contaminents from the surface and substrate of the metal as is proven by conductivity testing.
