| 摘要： | In the past, red lead primer was used to control corrosion on many common steel structures maintained by the Department of Defense (DoD). Thermal spray vitrification (TSV) technology has been demonstrated as a way to remove lead-based paint coatings from steel substrates that are not suitable for overcoating. In the TSV process, lead-based paints are thermally sprayed with a specially-formulated powdered glass feedstock that absorbs and encapsulates lead. When the glass solidifies and cools, it cracks and falls off. This waste product is collected and remelted onsite to complete the vitrification process. The final waste product is nonhazardous as determined by the Toxic Characteristic Leaching Procedure, and can be disposed of as a nonhazardous waste or recycled into value-added products. This report documents demonstrations of TSV conducted on a bridge at the Rock Island Arsenal, IL, and an aircraft hangar door at Marine Corps Base Kaneohe Bay, HI. The objectives of these demonstrations were to remove lead-containing paint from steel structures, meet applicable environmental and worker health and occupational safety standards, enable recoating of the substrate, collect data, and estimate production rates. |
