High-Power Lasers in Industrial Cleaning Applications

In the field of industrial cleaning, lasers are increasingly moving towards high-power systems. With the advancement of industrial automation and intelligence, high-power cleaning lasers not only improve cleaning efficiency but also, when integrated into automated production lines, enable a higher level of automation and intelligent production. Furthermore, with the deepening implementation of environmental strategies such as “carbon peak” and “carbon neutrality,” high-power lasers, as an eco-friendly cleaning method, are widely recognized for their promising market prospects. As technological breakthroughs continue and applications expand, high-power cleaning lasers are poised to usher in even broader market opportunities.

Main Applications of High-Power Laser Cleaning

Laser cleaning is one of the key applications for high-power pulsed lasers. It holds vast potential in fields such as rust removal, paint stripping, oil stain removal, mold cleaning, perovskite edge cleaning, and laser texturing.

  • Rust Removal: High-power lasers efficiently remove rust from metal surfaces. The higher the power, the stronger the rust removal capability and the higher the efficiency.
  • Mold Cleaning: Laser cleaning is highly effective in removing contaminants from molds without damaging the mold surface, thus extending its service life.
  • Perovskite Edge Cleaning: For perovskite batteries, high-power lasers can clean the membrane layer thoroughly without causing damage, facilitating the subsequent packaging process.
  • Laser Texturing: Using high-power pulsed lasers to texture material surfaces can significantly enhance the surface adhesion properties of materials.

Rust Removal

  • Light rust (e.g., floating rust): Efficiency can reach 3~6 m²/h.
  • Deep rust (e.g., beryllium oxide oxidation): Efficiency typically ranges from 0.5~1 m²/h.
  • Effect: Thorough cleaning with no damage to the substrate.
  • Efficiency: Multi-mode 1000W rust removal efficiency is about 122% higher than multi-mode 500W.
  • Note: The more severe the rust, the more obvious the advantage of higher power.

Paint Removal

  • Effect: Thorough cleaning without damaging the substrate.
  • Efficiency: Multi-mode 1000W paint removal efficiency is about 128% higher than multi-mode 500W.
  • Note: The thicker the paint and the brighter the color, the more apparent the advantage of higher power.

Laser Texturing

  • Texturing Efficiency: 9000mm²/s (50mm width, flying speed 180mm/s)

Perovskite Edge Cleaning

  • Edge Cleaning Effect: Overall translucency is good, no yellowing when placed on white paper, thorough cleaning, and no conductivity.

Single-mode cleaning lasers feature multiple pulse widths, high repetition frequencies, high beam quality, high energy density, and high peak power. These lasers are suitable for challenging applications involving strong adhesion, such as deep rust, oxidation layers, and thick paint, offering powerful cleaning capabilities and high efficiency.

Multi-mode cleaning lasers, on the other hand, are characterized by large spot sizes, high energy output, flat-top beam output, minimal substrate damage, and selectable single-pulse energies of 15mJ, 50mJ, or 100mJ. The use of multi-path synthesis significantly improves the stability of laser output. After 24 hours of continuous testing, the RMS value is <2%. These lasers are ideal for applications with light adhesion, such as yellow rust, oil stains, and paint, where ease of removal and no substrate damage are key requirements.
