Sandblasting rust removal

Sandblasting rust removal uses compressed air as the power source to propel abrasives such as quartz sand and emery at high speed onto the metal surface. The impact and cutting action of the abrasives remove rust, oxide scale, and impurities, resulting in a clean and roughened metal surface.

Process

Preparation: Inspect equipment, prepare abrasives, pre-treat the workpiece to remove oil stains, etc.

Sandblasting: Adjust pressure, angle, and distance, then begin operation to ensure uniform spraying.

Inspection: Check cleanliness and roughness according to standards to ensure compliance.

Post-treatment: Remove residual abrasives and dust, and apply protective measures such as painting.

Applications

Commonly used in industries such as shipbuilding, machinery, construction, and petrochemicals, for example, treating ship hulls, mechanical parts, steel structures, and the surfaces of pipelines and storage tanks.

Advantages and Disadvantages

- Advantages: High efficiency, excellent results, adaptable to various workpieces.

- Disadvantages: Generates dust, requiring dust removal equipment; demands high operator skill; relatively high cost.
