Copper Slag Abrasive for Industrial Sandblasting

Lianshun’s copper slag abrasive is a high-performance blasting media engineered for shipyards, oil pipelines, 橋樑, and steel structures. Moreover, it offers low free silica content, fast cutting action, 和 一致的表面輪廓, which ensures smooth and efficient blasting. 因此, it delivers excellent rust and coating removal while improving adhesion for protective coatings.

Key Benefits of Copper Slag Abrasive:

• Efficient Rust Removal: As a result of their angular shape, the particles actively remove tough rust and oxides from metal surfaces.

• Low Dust & Environmentally Friendly: Containing less than 1% free silica, this abrasive offers safer operations and reduces airborne dust during blasting.

• Consistent Surface Finish: Moreover, it provides uniform anchor patterns ideal for painting or coating applications.

• Cost-Effective: Due to its durability, it can be recycled for multiple blasting cycles, lowering the total project cost.

• Versatile Applications: Furthermore, it is widely used in shipbuilding, petrochemical plants, 管道, steel bridges, and infrastructure projects.

Industrial Applications of Copper Slag：

• Shipbuilding and Ship Repair – Widely used for blasting ship hulls, ballast tanks, and offshore platforms to achieve SA 2.5–3 surface cleanliness.
• 油, Gas, and Petrochemical Facilities – Ideal for cleaning pipelines, storage tanks, and refineries before coating.
• Monument and Building Facade Restoration – Effective for removing paint, dirt, and weathered layers from stone or concrete.
• Bridges, Tunnels, and Civil Infrastructure – Ensures strong coating adhesion and extended service life in harsh environments.
• Steel Structure Surface Preparation – Provides consistent anchor profiles for protective coatings on industrial steel frameworks.

FAQs about Copper Slag Abrasive：

• What is copper slag abrasive used for?
  Operators use copper slag abrasive in blasting to remove rust, paint, and old coatings from steel and concrete surfaces. They apply it in shipyards, 管道, 橋樑, and steel structures to achieve SA 2.5–3 surface cleanliness standards. Learn more about ISO 11126-3 standards for mineral abrasives.

• Is copper slag safe to use?
  Yes. Our copper slag contains less than 1% free silica, so it lowers dust and ensures safer blasting compared with traditional silica sand. We still recommend proper PPE during operation.

• How does copper slag compare to garnet?
  Copper slag cuts faster and reduces cost, which makes it ideal for heavy rust and scale removal. 石榴石, however, gives a finer surface finish for projects needing smoother profiles. For another option, check our Steel Grit abrasive.

• What mesh sizes are available?
  We supply copper slag in mesh sizes such as 5–8, 8–20, 10–20, 20–40, and 40–80. We can also produce custom sizing for specific project needs.

• What packaging options are offered?
  We offer copper slag in 25 kg bags shrink-wrapped on pallets or in 1000 kg jumbo bags with lifting loops. We also provide custom packaging for bulk orders.
