1. Material and Characteristics of the Cleaning Target
- Metal surfaces such as iron, steel, and aluminum generally require higher laser power (100W-1000W or higher) when cleaning rust, oil, or coatings, depending on the thickness of the stain and the hardness of the material.
- Non-metal surfaces such as plastic, wood, or stone require lower laser power (50W-200W) to avoid damaging the substrate.
- Sensitive materials such as artifacts and delicate electronic components require lower laser power (20W-100W) to ensure precise cleaning without damaging the surface.
2. Dirt type and thickness
- Light stains (such as grease and dust): A low-power laser cleaner of 50W-200W is usually sufficient.
- Heavy stains (such as thick rust, old paint, and oxide layers): A 200W-500W or even higher-power laser cleaner is required for improved efficiency.
- Stubborn coatings (such as thick paint and welding residue): A high-power laser cleaner of 500W-2000W may be required.
3. Cleaning Efficiency and Speed Requirements
- For small-area, delicate cleaning, such as mold cleaning and cultural relic restoration, low power (50W-100W) is sufficient, prioritizing precision.
- For large-area, industrial cleaning, such as ship rust removal and bridge maintenance, 500W-1000W or higher is recommended for improved efficiency.
- For mass production, high-power equipment (above 1000W) can significantly shorten cleaning times and is suitable for industrial assembly lines.
4. Equipment Type and Usage Scenario
- Pulsed laser cleaning machines: Suitable for precision cleaning. Power typically ranges from 50W to 500W. They offer high pulse energy and minimal thermal impact, making them suitable for sensitive materials.
- Continuous laser cleaning machines: Suitable for cleaning large areas and heavy dirt. Power typically ranges from 500W to 2000W. They offer high efficiency but also significant thermal impact.
- Portable equipment: Typically ranges from 50W to 200W and is suitable for small or mobile applications.
- Fixed industrial equipment: Power can reach over 1000W and is suitable for large workpieces or high-intensity applications.
