Introduction: The Role of Pulse Laser Cleaning Machine in Historical Preservation
Historical buildings are the cultural heritage of humanity, carrying the memories and stories of countless generations. However, these structures are often susceptible to damage from various sources, including fires. Post-fire restoration of historical buildings requires meticulous care to preserve their original integrity while removing soot, ash, and other contaminants. In recent years, pulse laser cleaning machines have emerged as a revolutionary tool for this purpose. This case study explores how pulse laser cleaning machines, particularly the Cupid Series Precision Laser Cleaning Machine, are transforming the restoration of historical buildings after fires.
Technical Comparison: Traditional Methods vs. Pulse Laser Cleaning Machine
Traditional Cleaning Methods
Historical buildings often have intricate architectural details and delicate surfaces. Traditional cleaning methods, such as mechanical scraping, chemical cleaning, or high-pressure water jetting, can be damaging and time-consuming. Mechanical scraping risks removing original material, while chemical cleaning may introduce harmful residues. High-pressure water jetting, while effective for some surfaces, can cause water damage to internal structures.
Pulse Laser Cleaning Machine
In contrast, pulse laser cleaning machines offer a non-contact, non-destructive cleaning solution. By utilizing high-energy laser pulses, these machines can precisely remove contaminants without damaging the underlying substrate. The Cupid Series Precision Laser Cleaning Machine, in particular, stands out with its advanced features and capabilities.
Core Advantages of Cupid Series Precision Laser Cleaning Machine
Large Laser Spot and High Single Pulse Energy
One of the key advantages of the Cupid Series is its use of a large laser spot and high single pulse energy fiber laser. This combination allows for efficient cleaning over a larger area, reducing the overall time required for restoration. The high energy of each pulse ensures that soot, ash, and other contaminants are quickly and effectively removed.
Simple Operation and Efficient Multiple Laser Cleaning Patterns
Operating the Cupid Series is straightforward, thanks to its user-friendly interface. The machine offers multiple laser cleaning patterns, allowing operators to tailor the cleaning process to the specific needs of each historical building. This versatility ensures that even the most delicate architectural details are preserved while contaminants are removed.

Multiple Safety Operation Locks and Parameter Storage
Safety is paramount when working on historical buildings. The Cupid Series includes multiple safety operation locks, ensuring that the machine can only be operated under safe conditions. Additionally, the machine can store multiple sets of working parameters, making it easy to switch between different cleaning tasks without the need for reconfiguration.

Almost all electrical parts of the Cupid Series are imported brands, known for their reliability and durability. These components can be replaced anytime and anywhere, minimizing downtime and ensuring the machine is always ready for use.

No Damage to the Base Material
One of the most significant advantages of pulse laser cleaning is its ability to remove contaminants without damaging the base material. The Cupid Series is designed to precisely control the energy and duration of each laser pulse, ensuring that only the contaminants are removed and the original structure remains intact.
High-Speed Cleaning Head with E-Stop Button
The high-speed cleaning head of the Cupid Series, equipped with an E-Stop button, provides faster emergency response in case of any unexpected situations. This feature ensures the safety of both operators and the historical building during the cleaning process.
Real-Time Alarm Feedback and Laser Shutdown
For added safety, the Cupid Series includes real-time alarm feedback and laser shutdown features. If any anomalies are detected, the machine immediately alerts the operator and halts the laser, preventing potential damage to the structure or personnel.
Integrated Shielding Gas Function
The integrated shielding gas function of the Cupid Series extends the service life of the lens and enhances working efficiency. By protecting the lens from contaminants and debris, this feature ensures that the machine maintains optimal performance over extended periods.
F-Theta Focus Lens Mode for Uniform Energy Distribution
The F-theta focus lens mode of the Cupid Series provides better uniform energy distribution on the surface, resulting in improved cleaning quality. This feature ensures that contaminants are removed evenly across the entire surface, preserving the original aesthetics of the historical building.
Easier Clean Mode for Efficient and Labor-Saving Cleaning
The Cupid Series offers an easier clean mode, making the cleaning process more efficient and labor-saving. This feature allows operators to quickly and easily remove contaminants without the need for excessive manual effort.
Support for External Control and Other Functions
The machine supports external control, parameter call, safety door, and other functions, providing flexibility and convenience for various restoration tasks. This makes the Cupid Series a versatile tool for a wide range of applications, including post-fire restoration of historical buildings.
European Standard Safety Circuit Design
With a European standard safety circuit design, the Cupid Series ensures reliable operation even in the event of sudden power outages. This feature provides peace of mind for operators and protects the historical building from potential damage.
