Cavitation damage repair involves restoring propeller surfaces eroded by bubble implosions, often through welding and polishing. Ship propeller repair addresses dents, cracks, and material loss to restore performance and efficiency. Both processes require precision to maintain hydrodynamic balance and prolong propeller lifespan.
Size: Typically customized to match propeller dimensions, ranging from small (under 1 meter) to large (over 5 meters).
Grade: High-performance epoxy or polymer-based compounds, often meeting MIL-SPEC or ASTM standards.
Viscosity: Low to medium (500–5,000 cP) for easy application and adhesion.
Buoyancy: Neutral to slightly negative to avoid affecting propeller balance.
Material: Epoxy resins, polyurethane, or metal-filled composites (e.g., aluminum, bronze).
Curing Time: 2–24 hours, depending on temperature and product formulation.
Hardness: 80–90 Shore D after curing for durability.
Adhesion Strength: >20 MPa to ensure bonding to propeller metals (e.g., nickel-aluminum bronze, stainless steel).
Operating Temperature: -30°C to +120°C for marine environments.
Corrosion Resistance: High, with saltwater and chemical resistance.
Application Method: Brush, spray, or trowel, often with surface prep (e.g., grit blasting).
Ropes, paints, safety gear, and workshop tools.
Fresh/canned food, bonded stores, and PPE kits.
Air/sea freight with port-to-vessel handover.
