Pulse Laser Cleaning Machines: A Comprehensive Guide
Pulse laser cleaning machines are rapidly gaining popularity in various industries for their efficiency and precision in surface cleaning. These machines utilize short bursts of high-intensity laser energy to remove contaminants without damaging the underlying substrate. This guide delves into the technology, features, and applications of pulse laser cleaning machines, focusing on the offerings of several prominent Chinese manufacturers like Demark (www.demarkChina.cn), DMK Laser (www.laserdmk.com), MRJ-Laser (www.mrj-lasermark.com), and Hantencnc (hantencnc.com).
Understanding the Technology
Pulse laser cleaning leverages the principle of selective absorption. The laser’s wavelength is chosen to be preferentially absorbed by the contaminant, rather than the substrate. This selective absorption causes the contaminant to heat up rapidly, leading to its vaporization, ablation, or spallation. The process is non-contact, minimizing the risk of damage to the underlying material. The pulse duration and frequency can be adjusted to optimize cleaning for various materials and contaminants. Demark’s website (www.demarkChina.cn) provides detailed explanations of their laser cleaning principles.
