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.

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.
