The cleaning principle of high-power laser cleaning machine is based on the strong absorption of laser energy by contaminants. When the high-power laser beam is focused on the surface of the object to be cleaned, the contaminants absorb the laser energy and rapidly heat up. With the increase of temperature, the contaminants will expand and burst, causing the surface of the object to be cleaned to detach from the contaminants. As a result, the contaminants are removed without damaging the surface.
In addition to thermal effect, the high-power laser cleaning machine also utilizes the shock wave effect. When the contaminants absorb the laser energy, they will undergo a rapid and intense expansion, leading to a shock wave that can further remove the contaminants from the surface. This shock wave effect plays a crucial role in cleaning hard contaminants that are tightly adhered to the surface.
Furthermore, the high-power laser cleaning machine can selectively remove contaminants without damaging the substrate. By adjusting the laser parameters such as pulse width and energy, the laser beam can be precisely controlled to only remove the contaminants, leaving the surface intact. This selective cleaning ability is particularly useful for delicate objects or materials with different properties.
In summary, the high-power laser cleaning machine achieves efficient and precise cleaning by utilizing the thermal effect, shock wave effect, selective cleaning ability, and non-contact cleaning solution. With its advanced technology, it is widely applied in various industries such as aerospace, automotive, electronics, and cultural heritage preservation, providing a highly effective and eco-friendly cleaning solution.
