With the continuous development of technology, laser cleaning technology has attracted more and more attention in the field of metal surface treatment. Among them, laser rust removal technology is favored for its high efficiency, environmental protection and accuracy.
This article will explore in depth how to use laser technology to effectively remove rust on metal surfaces, as well as the working principle, equipment type, application field, preparation and cost of the technology.
How does laser cleaning work?
The working principle of laser cleaning is based on the interaction of laser light with matter. When a high-energy laser beam irradiates the rust layer, the rust layer quickly absorbs the laser energy and evaporates or decomposes instantaneously. This process is called laser ablation. Laser cleaning typically uses pulsed lasers, which provide high peak power to ensure rapid and effective rust removal while avoiding excessive heat transfer to the substrate and preventing damage to the substrate.
Types of Handheld Laser Rust Removal Machine
Continuous Wave (CW) Laser Cleaners:
These cleaners use a constant, low-powered laser beam to heat and vaporize rust and other contaminants on the surface of the material. CW cleaners are well-suited for removing light rust, paint, and oil from flat surfaces.
Pulsed Laser Cleaners:
These cleaners use short, high-powered laser pulses to break down rust and other contaminants on the surface of the material. Pulsed cleaners are more powerful than CW cleaners and can be used to remove heavier rust, as well as weld marks and coatings.
How Does Laser Cleaning Technology Function?
The core of laser cleaning technology lies in the precise control of laser parameters. Choosing the right laser wavelength and power is key to effective cleaning. Typically, lasers are equipped with specialized software that allows operators to adjust laser parameters for different materials and levels of rust. In this way, laser energy can be precisely controlled to ensure efficient rust removal without damaging the substrate. Cooling systems and protective devices are also important components of laser cleaning equipment to ensure operational safety and stable equipment operation.
Benefits Of Removing Rust with a Laser
- Non-contact cleaning: The laser rust removal process does not require contact with the substrate, avoiding wear and damage caused by traditional mechanical methods.
- Environmentally friendly: Laser rust removal does not require chemicals, avoiding environmental pollution and chemical disposal problems.
- High precision: The laser beam can be precisely focused on the rusted area to achieve local cleaning without affecting the surrounding uncorroded areas.
- Versatility: Not only can lasers remove rust, they can also remove paint, grease, and other contaminants.
Applications of Laser Rust Removal in the Industrial
Automobile manufacturing: used to remove rust on the body and parts to improve product quality and service life.
Aerospace: For high-precision cleaning of aircraft parts to ensure safety and performance.
Manufacturing industry: used for the maintenance of equipment and tools to extend their service life and work efficiency.
Will Laser Rust Removal Remove Paint?
Laser rust removal usually also removes layers of paint from the surface because the laser heats and vaporizes the paint material. Therefore, special attention needs to be paid when using laser rust removal. If you do not want to remove paint, you can protect the paint layer from being affected by adjusting laser parameters or using masking technology.
How to Prepare Surfaces for Laser Paint Removal?
- Clean the surface: Make sure the surface is free of grease, dust and other contaminants, which helps the laser energy to be transmitted efficiently.
- Mask non-target areas: Use protective material to cover areas that do not require paint removal to prevent laser damage.
- Choose the right laser parameters: Adjust laser power and scanning speed according to paint type and thickness to ensure efficient paint removal without damaging the substrate.
Why are Laser Rust Removal So Expensive?
