The application of laser cleaning in paint removal
Paint is a chemical mixture coating that can firmly cover the surface of an object, providing protection, decoration, signage, and other special purposes. The authoritative book "Coating Technology" in the Chinese coating industry defines it as follows: "Coatings are a type of material that can be coated on the surface of objects using different construction techniques to form a solid film with strong adhesion, certain strength, and continuity. The film formed in this way is generally called a coating film, also known as a paint film or coating."
Laser cleaning equipment plays an important role in many industries, such as automotive manufacturing, semiconductor wafer cleaning, precision parts processing and manufacturing, building exterior wall cleaning, cultural relic protection, circuit board cleaning, precision parts processing and manufacturing, LCD display cleaning, gum residue removal, grease removal, paint removal, and so on.
Laser can also remove all coatings on the substrate at once and selectively layer by layer. Portable systems are designed specifically for metal structure paint removal, and the orientation and control of the laser beam must be accurate when removing selected areas.
Laser cleaning has the following advantages:
1. Green cleaning: No chemical agents are used, and the waste after cleaning is solid and harmless powder, which can completely solve the environmental pollution problem caused by chemical cleaning.
2. Non damaging cleaning: During cleaning, there is no grinding, no contact, and no damage to the substrate.
3. Low cost cleaning: The equipment only consumes a very small amount of electricity during operation.
4. Precision cleaning: It can perform precise cleaning on designated areas.
5. Automated cleaning: It can be equipped with automated equipment to achieve automated cleaning.

Laser cleaning: advantages in rust removal
Laser cleaning and rust removal, as a high-tech product for the new generation of industrial surface cleaning, has played a significant role in rust removal. Rusting of metals is inevitable and a chemical reaction, essentially an oxidation reaction of metals. The most common rusting phenomenon is when iron products are exposed to air for a long time and undergo oxidation reaction with oxygen, or are corroded into oxides by oxygen elements in water. However, after rusting, they need to be cleaned of the rust on the metal surface before reuse. -
Five advantages of laser cleaning compared to traditional cleaning
There are various cleaning methods for traditional cleaning, including mechanical friction cleaning, chemical corrosion cleaning, liquid solid strong impact cleaning, high-frequency ultrasonic cleaning, and other traditional cleaning methods. -
Application of laser cleaning for cleaning before and after welding
Laser cleaning can replace traditional cleaning methods such as pre-treatment before welding and post welding. It can perform precise cleaning on welded or post welded metal parts of automotive components, remove paint from repair parts in the automotive aftermarket, and achieve customer satisfaction in the automotive manufacturing market. -
The application advantages of small laser cleaning machines in various industries
A small handheld laser cleaning machine does not require media, chemical reagents, or water, and can use laser to remove and clean the coating layer. The principle of laser cleaning is to use high-frequency and high-energy laser pulses to irradiate the surface of the workpiece. The coating layer can instantly absorb the focused laser energy, causing oil stains, rust spots or coatings on the surface to evaporate or peel off instantly. This is a high-speed and effective cleaning method for removing surface attachments or coatings. The short duration of the laser pulse will not harm the metal substrate under appropriate parameters.
