Can copper slag sandblasting truly serve as the economical solution for large-area surface treatment in shipbuilding

II. Basic Characteristics of Copper Slag Blasting

Copper slag is a byproduct of copper smelting. After simple processing, it forms a high-hardness, sharp-edged abrasive. It requires no complex synthesis, and the raw material cost is 30%-40% lower than traditional blasting materials. It also allows for waste recycling, aligning with the concept of green shipbuilding.

III. Core Advantages of Copper Slag Blasting in Shipbuilding

(I) Outstanding Efficiency and Shortened Construction Period :

Copper slag blasting has a strong impact force, quickly removing rust, scale, and old coatings from the hull surface. It can process 50-80 square meters per hour, far exceeding manual grinding (10-15 square meters/hour), significantly shortening the ship construction and maintenance period and reducing hidden costs.

(II) Compliant Processing, Ensuring Corrosion Protection Quality:

It forms uniform anchor patterns on metal surfaces,providing a good adhesion base for subsequent anti-corrosion coatings, reducing rework, meeting the shipbuilding industry's SA2.5-SA3 cleanliness standards, and lowering long-term maintenance costs.

(III) Controllable Costs, Suitable for Large-Scale Operations:

Raw material prices are low; coarse-grained copper slag is recyclable and more economical than steel grit or garnet sand. Using coarse-grained copper slag in shipbuilding can save even more material costs, making it ideal for the shipbuilding industry's large-scale processing needs.

(IV) Safe and Environmentally Friendly, Reducing Operational Risks:

Low dust levels and compliant free silicon content, combined with dust removal equipment, control pollution and reduce worker operational risks. It also enables industrial waste recycling, meeting environmental protection requirements.

IV. Conclusion:

Copper slag sandblasting combines high efficiency, low cost, high quality, and safety and environmental protection, precisely matching the large-area surface treatment needs of the shipbuilding industry. It is the optimal choice for shipyards to control costs and ensure quality.
