【Pain Points of Traditional Processes】Three Major Bottlenecks in Ship Cleaning
① Severe environmental pressure: The dust produced by sandblasting and industrial waste liquid from pickling involve complex treatment procedures and high governance costs. Shipyards struggle to pass routine environmental assessments, leading to severe restrictions on production and operation.
② Conflict between efficiency and quality: Manual weld cleaning and rust/paint removal with angle grinders is extremely inefficient. Improper manual operation easily scratches and damages the base material, impairing the overall construction quality of ships.
③ High implicit costs: Traditional processes consume large quantities of consumables and rely heavily on skilled workers. The growing difficulties in recruitment and rising labor costs have steadily increased the comprehensive labor and operation costs of ship enterprises year by year.
【Technological Breakthrough】The Revolutionary Upgrade of Laser Cleaning Technology
Laser cleaning adopts high-frequency and high-energy laser beams to irradiate workpiece surfaces. Rust, oil stains and old coatings on the hull instantly absorb laser energy, expand thermally, and peel off from the base material in the form of steam or plasma. The entire non-contact cleaning process requires no mechanical grinding and causes no extensive thermal impact. It enables precise targeted cleaning without damaging the base material or producing secondary pollution, completely revolutionizing traditional ship cleaning processes.
【3 Core Application Scenarios】Redefining New Standards for Ship Cleaning
① Large-area Rust and Paint Removal for Hull Exteriors
Traditional sandblasting requires the erection of closed dust-proof sheds, resulting in cumbersome procedures and strict site limitations. In contrast, Eagle Laser cleaning can be operated directly in open outdoor and dock environments with zero dust emission, fully complying with environmental protection production standards. Actual tests by a large ship repair yard show that laser cleaning boosts hull rust and paint removal efficiency by 3-5 times, delivering uniform and stable surface roughness that fully meets subsequent ship coating requirements. It eliminates tedious secondary polishing procedures and greatly shortens the construction cycle.
② Removal of Post-weld Oxide Scales and Splashes
A large number of oxide scales, welding slags and splashes remain around welds after the welding of ship steel structures. Traditional grinding with angle grinders easily damages the base material and destroys surface flatness. Eagle Laser cleaning accurately strips surface oxide layers and impurities while retaining the original luster of the metal base. It delivers smooth and aesthetic welds, raising the workpiece flaw detection pass rate to over 99%, reducing repeated inspection and rework, and significantly shortening the overall ship inspection cycle.
③ Decontamination of Marine Precision Valves and Instruments
For high-value marine precision components, the non-contact feature of Eagle Laser cleaning brings outstanding advantages. The process generates no mechanical stress or base material wear and does not alter the physical properties and precision of components. By precisely adjusting laser pulse parameters, it achieves micron-level refined decontamination, perfectly solving the cleaning challenges of marine precision valves, sensors and small precision parts, and meeting the high-precision construction requirements of high-end shipbuilding.
