  1. Copper Slag Blasting in Shipbuilding and Marine Industries Introduction to Copper Slag Blasting Copper slag blasting is a highly effective surface preparation method used in shipbuilding and marine industries. It involves using copper slag, a byproduct of copper smelting, as an abrasive to remove rust, old paint, and contaminants from metal surfaces before coating or painting. Why is Copper Slag Used in Shipbuilding and Marine Industries? Ships and marine structures are exposed to harsh environmental conditions, including:✅ Saltwater corrosion✅ Marine growth (algae, barnacles, etc.)✅ Rust and oxidation✅ Extreme weather conditions To maintain structural integrity and extend the lifespan of ships and offshore structures, proper surface preparation is crucial before applying protective coatings.

  2. Benefits of Copper Slag Blasting in Marine Applications • 1. Superior Surface Cleaning • Removes rust, scale, and old coatings efficiently • Creates an ideal surface profile for paint adhesion • 2. Cost-Effective Alternative • Lower cost than traditional abrasives (e.g., silica sand) • Reusable up to multiple cycles • 3. Environmentally Friendly • Contains low free silica, reducing health hazards • Less dust generation, improving worker safety • 4. High Productivity & Faster Blasting • Denser than sand, leading to faster cleaning • Reduces overall blasting time, increasing efficiency • Applications in the Shipbuilding & Marine Industry • 1. New Ship Construction • Surface preparation before applying protective coatings • Ensures longevity of ship hulls and decks • 2. Ship Repair and Maintenance • Removes barnacles, rust, and corrosion from ship surfaces • Prepares ships for repainting and anti-fouling coatings • 3. Offshore Platforms & Marine Structures • Used for oil rigs, bridges, and port structures exposed to seawater • Helps maintain the durability of metal structures

  3. Process of Copper Slag Blasting in Shipbuilding 1️⃣ Surface Inspection – Identify rust, corrosion, or paint removal areas2️⃣ Blasting Setup – Use copper slag with high-pressure equipment3️⃣ Blasting Operation – Clean surface using controlled pressure4️⃣ Dust & Waste Collection – Use dust extraction systems for safety5️⃣ Final Surface Inspection – Ensure proper surface profile before coating6️⃣ Coating Application – Apply marine-grade protective paint Conclusion Copper slag blasting is a cost-effective, efficient, and eco-friendly method for surface preparation in shipbuilding and marine industries. It ensures rust-free, well-prepared surfaces, leading to better paint adhesion, increased durability, and reduced maintenance costs for ships and offshore structures.
