Which Material Can Be Used for The Laser Cleaning

Nov 30, 2023

Laser is an incredible technology that is being used in almost every industry to create products that people around the world use. Laser cleaning is becoming a popular method for removing thin layers of rust and dirt from many types of surfaces. Cleaning surfaces with lasers can reduce the environmental hazard associated with traditional methods such as chemical etching and media sandblasting.

 

Why choose laser cleaning?

Laser cleaning is a new technology that is becoming increasingly common in handheld mobile systems. Using laser cleaning instead of sandblasting or chemical cleaning has many costs, health, safety, and environmental benefits.

Recently, industrial cleaning applications have been adjusted, including a wide range of pulse laser cleaning or coating removal systems for removing paint from fragile surfaces, stripping insulation from conductors, carving surfaces by ablation, or removing sulfide residues from molds.

The development of laser surface cleaning is influenced by the demand for nonabrasive and nonhazardous cleaning processes, which are also suitable substitutes for chemicals or sandblasting systems. A key issue related to most traditional cleaning technologies is the wear of the substrate and its negative impact on the environment. Sandblasting can damage fragile surfaces and generate a large amount of waste. The use of chemical solvents can generate liquid waste and potentially hazardous vapors. These issues led to the development of the first batch of laser systems used for this purpose.

 

From laboratories to industrial factories, the advantages of lasers in surface cleaning of organic and inorganic materials are attracting new applications every day.

 

What materials can be used for laser cleaning?

Rust removal: One of the most common uses of laser cleaning solutions is rust removal. This is done to prepare for welding or bonding, improve efficiency, or restore historical buildings and other products to their previous glory. The most common metals that can rust include iron., cast iron, wrought iron, and steel.

 

Oxidation removal: Although laser cleaning is an effective rust removal method, it is also suitable for metals that do not contain iron but still form oxide coatings. Oxides can alter the integrity of products and form a protective layer. Although this may sound positive, what actually happens is that your product is decomposing, and removing the oxide layer will further worsen it. Laser cleaning not only removes the protective layer, but also completely removes pollutants and oxides from the product, protecting it from further damage. The most common nonferrous metals include aluminum, bronze, copper, gold, and platinum.

 

Welding/Bonding preparation: Pollutants such as oxides, grease, mold, and paint can prevent parts from welding or bonding together. This greatly affects the strength of your product. Laser cleaning can even remove the thickest pollutants on the product surface without affecting the integrity of the substrate, allowing you to fix the parts by welding or bonding.

 

Harmful paint removal: Removing paint can be a long and dangerous process, especially when using chromium or lead based paints. Due to the use of pulses to absorb and remove pollutants in laser cleaning, you can safely remove hazardous paint from metal applications without generating additional waste or endangering the safety of operators.

Nonmetallic products suitable for laser cleaning

Ceramic products: Like cleaning metals, laser ablation of ceramics is achieved by irradiating surface contaminants with thousands of laser pulses per second. This process is safe for the substrate ceramic layer and generates very little waste - which is usually captured by the built-in nozzle of the laser. Like any laser cleaning application, the key to successful ceramic cleaning is a properly calibrated laser solution. You need a laser system that can reach the ablation threshold required to clean the pollutant layer without damaging the product you are cleaning. Therefore, it is crucial to choose a laser with the correct power level, settings, optical components, and delivery system.

 

The power of the cleaning laser is sufficient to remove the rust layer on warships, but it can also be designed for milder cleaning that requires very precise cleaning, such as removing dirt and bacteria from natural stones. This includes marble, granite, limestone, concrete, and so on. Our laser solutions have been used in extremely delicate projects such as the restoration of statues, figures, and decorations, as well as larger surfaces such as building facades. One of the greatest benefits of using laser ablation to clean natural stones is that it can gently remove the pollutant layer without damaging the underlying substrate.
