The Principle of Laser Composite Cleaning

The advantage of laser composite cleaning is that it combines the functions of continuous laser and pulsed laser at the same time to form a processing characteristic of 1+1>2. Its principle is mainly through the semiconductor continuous laser as the heat conduction output, so that the attachment to be cleaned absorbs energy to generate vaporization and plasma cloud, and forms a thermal expansion pressure between the metal material and the attachment, reducing the bonding force between the two layers. When the pulsed laser outputs a high-energy pulsed laser beam, the generated vibration shock wave will cause the attachments with weak bonding force to be directly separated from the metal surface, so as to achieve rapid laser cleaning.

Advantages of Laser Composite Cleaning

1. Used for cleaning thicker coating materials. Due to the large energy output of a single laser with multiple pulses and the high cost of high-power pulsed lasers, laser cleaning of thick coating materials is limited. The use of pulsed laser-semiconductor laser combined cleaning can quickly and effectively improve the cleaning quality, and the substrate is not easy Causes damage, so it is suitable for cleaning thicker coating materials.

2. Used in laser cleaning of high reflective materials such as aluminum alloy. Single laser cleaning aluminum alloy and other surface oxide layers has problems such as high reflectivity. However, pulse laser-semiconductor laser combined cleaning is used to increase the energy absorption rate of the metal surface oxide layer due to the thermal transmission of the semiconductor laser, making the pulse laser The beam can peel off the oxide layer faster, thereby more effectively improving the removal efficiency.

Laser Composite Cleaning Application Field

Laser composite cleaning can be applied to the cleaning of thick coatings and strong adhesion attachments. It can remove resin, paint, oil, stains, dirt, rust, coatings, coatings and oxide layers on the surface of objects, and it is widely used in the industry, covering ships , Auto repair, rubber molds, high-end machine tools, track and environmental protection, etc.
