Hybrid laser cleaning machine system is the newest technoogy from Questt laser.
QA-LC200-1000C is a hybrid laser cleaning machine system, which adopt both pulsed fiber laser source and continuous fiber laser source.
The laser power range from 200W to 2000W.
The advantage of laser composite cleaning is that the continuous laser and pulsed laser are functionally composited at the same time to form a processing characteristic of 1+1>2. The 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 binding force to be directly separated from the metal surface, thereby realizing rapid laser cleaning.
1. Better to clean thicker coating materials. Due to the large energy output of a single laser with multiple pulses, the high cost of high-power pulsed lasers limits the laser cleaning of thick coating materials, and the use of pulsed laser-semiconductor laser composite 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. Better cleanhigh 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, due to the thermal transmission of semiconductor laser, increases the energy absorption rate of the metal surface oxide layer, making the pulse laser The beam can peel off the oxide layer faster, thereby more effectively improving the removal efficiency.
