Handheld laser cleaning machine 2000 watts Principle of laser surface cleaning

In recent years, with more and more strict environmental protection laws and regulations in China, the traditional industrial rust removal and decontamination are more and more unsuitable for the current production demand due to its high pollution and high cost. Is it effective at this stage

High rate, low cost, no damage, no pollution, new industrial way of rust and decontamination? Now Dongguan Zhengxin Laser Technology Co., Ltd. tells you a new way of industrial rust removal - excitation laser cleaning machine 2000 watts

Light cleaning technology.


handheld laser cleaning machine 2000 watts Principle of laser surface cleaning:

The pulsed Nd:YAG laser cleaning process depends on the characteristics of the light pulse generated by the laser based on the interaction between the high intensity beam, the short pulse laser and the contamination layer

Photophysical reaction. Its physical principles can be summarized as follows:

A The laser beam is absorbed by the contaminated layer on the surface to be treated.

H The absorption of large energy forms rapidly expanding isoponitons (highly dissociated unstable gases). Generate shock wave

C shock waves break contaminants into fragments and remove them.

D light pulse width must be short enough to avoid heat accumulation that damages the treated surface.

E Experiments show that plasma is generated on the metal surface when there is oxide on the metal surface

Plasma is only produced if the energy density is above a threshold, which depends on the contaminant or oxide layer being removed. This threshold effect is effective in ensuring the safety of the base material

Effective cleaning is very important. There is a second threshold for plasma. If the energy density exceeds this threshold, the substrate material will be destroyed. In order to ensure the safety of the base material

For effective cleaning, the laser parameters must be adjusted according to the situation so that the energy density of the light pulse is strictly between the two thresholds.

Each laser pulse removes a certain thickness of contamination layer. If the contamination layer is thick, multiple pulses are required to clean it. The number of pulses required to clean the surface depends on the level of surface contamination. An important result of the two thresholds is the self-control of the cleaning. A light pulse with a high energy density first threshold will remove contaminants until the substrate material is reached. However,

The substrate will not be damaged because of its low energy density and failure interval of dry substrate material.

Advantages of laser surface cleaning laser cleaning machine 2000 watts:

Compared with mechanical friction cleaning, chemical corrosion cleaning, liquid solid strong impact cleaning, high-frequency ultrasonic cleaning and other traditional cleaning methods, laser cleaning has obvious advantages.

1 laser cleaning is a "green" cleaning method without the use of any chemical agents and cleaning liquid cleaning down the waste is basically a solid powder small volume easy to store recyclable

To easily solve the environmental pollution problems caused by chemical cleaning:

2. The traditional cleaning method is often contact cleaning on the surface of the cleaning object has mechanical force damage the surface of the object or the cleaning medium attached to the surface of the cleaned object, can not be removed

The non-abrasive and non-contact laser cleaning of secondary pollution makes these problems easily solved;

3 Laser can be transmitted through optical fiber with robot hand and robot can easily achieve remote operation can clean the traditional method is not easy to reach the part which can be used in some dangerous places

To ensure the safety of personnel;

4. Laser cleaning can remove various types of pollutants on the surface of various materials to achieve cleanliness that cannot be achieved by conventional cleaning. Moreover, it can selectively clean the contaminants on the surface of the material without damaging the material surface:

5. Laser cleaning efficiency is high, save time;

6. Buy laser cleaning system although early one-time investment is high but cleaning system can be long-term stable use of low operating cost without consumables to our company's laser cleaning machine for example, every hour of transport

The line cost is only about 1 yuan, and more importantly, it can be easily automated

Comparison between laser rust removal and traditional rust removal and decontamination:

Application of laser cleaning:

Laser cleaning can not only be used to clean organic pollutants can also be used to clean inorganic materials including metal corrosion, metal particles, dust and so on. Here are some practical applications in steam

Car manufacturing, semiconductor wafer cleaning, precision parts processing and manufacturing, military equipment cleaning, building cleaning, cultural relics protection, circuit board cleaning, precision parts processing and manufacturing, liquid crystal

Monitor cleaning, gum residue removal and other areas can play an important role.
