Laser cleaning machine is the use of high energy density laser beam irradiate the surface of the workpiece, so that the surface of the dirt, rust or coating instant evaporation or peeling, so as to

achieve a clean green energy-saving and efficient industrial weapon, practical applications can quickly remove paint, rust, oxide, oil stains and so on. It is a new technology based on the 

interaction effect of laser and substance, different from the traditional mechanical cleaning method, chemical cleaning method and ultrasonic cleaning method (wet cleaning process), it does 

not  need any ozone layer destruction of CFC organic solvents, no pollution, no noise, harmless to the human body and the environment, is a real green environmental protection cleaning 

technology.

Laser cleaning machine has two kinds of continuous cleaning machine and pulse cleaning machine, first of all, let's understand the difference between continuous laser and pulse laser.

The biggest difference between pulsed laser and continuous laser is the output waveform:

1. Pulsed laser: Pulsed laser is a kind of pulse-like laser, its output waveform is pulse, its energy is very high, can be highly concentrated in a short time, forming a series of short and strong light

pulses. High peak power, small heating effect, high precision, suitable for micro-machining. In the industrial field has a wide range of applications, such as laser marking, laser cutting, laser 

welding and so on.

2. Continuous laser: A continuous laser is a continuously oscillating light, and its output waveform is a continuous waveform. It can continuously output a stable beam without significant pulse

intervals. Its output power is relatively stable, suitable for the need to stabilize the light source for a long time, its application in the medical and scientific fields is very wide, such as laser

treatment, measurement, detection, optical imaging and so on.

For laser cleaning, large-scale cleaning of rust, etc., you need to use continuous laser cleaning. The cleaning of ancient relics, non-metals, molds or items requiring no damage to the surface of the material requires the use of pulsed laser cleaning.

Pulsed laser cleaning machines have significant advantages over traditional cleaning methods:

1. High efficiency ‌ :
Pulsed laser cleaning machine equipment can quickly remove a large number of pollutants in a short time, significantly improving cleaning efficiency. The high energy density and short pulse
width of the laser beam make the cleaning process faster and more efficient ‌.

‌2. Non-damaging: 

In the process of pulsed laser cleaning, the interaction between the laser beam and the surface of the object to be cleaned is very small, and will not cause damage to the surface of the object.

The short pulse characteristics and high energy density of the laser pulse make the thermal impact of the cleaning process on the object substrate very small, avoiding the thermal damage that 

may be caused by traditional cleaning methods ‌.

‌3. Environmental protection:

There is no need to use chemical cleaning agents in the pulse laser cleaning process, which reduces the pollution to the environment. It uses the interaction between the laser beam and 

pollutants, through the mechanism of photothermal effect, photochemical effect and photomechanical effect, so that the pollutants quickly decompose and peel off, so as to achieve the 

purpose of cleaning, is an environmentally friendly and pollution-free cleaning method ‌.

‌4. Wide applicability: 

Pulsed laser cleaning machine is suitable for surface cleaning of various materials and shapes, including metal, non-metal, flat, curved surface and so on. This makes it have a wide range of

applications in industrial production ‌.
