Product Description

The laser cleaning system is the high-tech product of the new generation of metal surface cleaning. It can be widely used for a range of traditional or industrial cleaning processes, such as chemistry, ship industry, aviation industry, automotive industry, cultural relics restoration, molding industry, railway industry, construction industry, oil pipeline, grease, and ground cleaning. It has the characteristics of no grinding, non-contact, low thermal efficiency, environmentally friendly, and suitable for various materials. It is considered to be the most reliable. So the laser cleaning machine is defined as the most effective new generation cleaning solution.

Technical parameters

Principle of laser cleaning?

The cleaning process of pulsed laser relies on the characteristics of the light pulse generated by the laser, based on the photophysical reaction caused by the interaction between the high-intensity beam, the short-pulse laser and the pollution layer. The physical principles can be summarized as follows:
a) The light beam emitted by the laser is absorbed by the contamination layer on the surface to be treated.
b) Absorption of large energy forms a rapidly expanding plasma (a highly ionized unstable gas), which generates shock waves.
c) The shock wave turns pollutants into fragments and is rejected.
d) The light pulse width must be short enough to avoid heat accumulation that damages the processed surface.
e) Experiments show that when there is oxide on the metal surface, plasma is generated on the metal surface. Plasma is only generated when the energy density is higher than the threshold, which depends on the contamination layer or oxide layer being removed. This threshold effect is very important for effective cleaning while ensuring the safety of the base material. There is a second threshold for the appearance of plasma. If the energy density exceeds this threshold, the base material will be destroyed. In order to perform effective cleaning under the premise of ensuring the safety of the base material, the laser parameters must be adjusted according to the situation so that the energy density of the light pulse is strictly between two thresholds.
Each laser pulse removes a certain thickness of the contamination layer. If the contamination layer is relatively thick, multiple pulses are required for cleaning. The number of pulses required to clean the surface depends on the degree of surface contamination. An important result produced by the two thresholds is the self-control of cleaning. The light pulse with an energy density higher than the first threshold will keep out contaminants until it reaches the base material. However, because its energy density is lower than the destruction threshold of the base material, the base is not damaged.
