What is a laser cleaning machine
The billet has suffered from long-term exposure, affecting both aesthetics and performance. Although stainless steel has appeared with the development of modern technology and is still used in daily life, it is really time-consuming and labor-intensive to use stainless steel to renovate old houses. Also, not all products are available in stainless steel, so descaling becomes a headache.
There are various cleaning methods in the traditional cleaning industry, most of which use chemical agents and mechanical methods for cleaning. Today, as my country’s environmental protection regulations become more and more stringent and people’s awareness of environmental protection and safety is increasing, the types of chemicals that can be used in industrial production cleaning will become fewer and fewer. How to find a cleaner and non-damaging cleaning method is a question we have to consider. Laser cleaning has the characteristics of non-abrasive, non-contact, no thermal effect and suitable for cleaning objects of various materials, and is considered to be a reliable and effective solution. At the same time, laser cleaning can solve problems that cannot be solved with traditional cleaning methods.
When there are sub-micron contamination particles stuck to the surface of the workpiece, these particles tend to stick very tightly and cannot be removed by conventional cleaning methods. Cleaning the surface of the workpiece with nano-laser irradiation is very effective. Also, because the laser cleans the workpiece without contact, it is very safe to clean precision workpieces or their fine parts, ensuring their accuracy. Therefore, laser cleaning has advantages in the cleaning industry.
High-energy lasers are very effective in removing rust. The laser burns away metal surfaces such as rust, paint, etc. while using the reflective properties of the metal. Make sure the part itself is not damaged.
The principle of this laser descaler is that when rust is subjected to high temperature, it will evaporate instantly. After plasma separation, due to the high reflectivity of the underlying metal to light, the rust-removed part will not be damaged even if it is exposed to laser. Therefore , this laser descaling method is effective and safe and can even clean the corners of components such as letters and bolts. So whether rust is difficult to remove or not, it can be tackled with ease. As long as light can reach it, rust has nowhere to hide.
Why can laser be used for cleaning? Why does it not cause damage to the objects being cleaned? First understand the nature of laser. To put it simply, lasers are no different from the light (visible light and invisible light) that follow us around us. The only difference is that lasers use resonant cavities to focus light in the same direction, and have simpler wavelengths, coordination, etc. The performance is better, so in theory, light of all wavelengths can be used to form lasers. However, in fact, there are not many media that can be excited, so the ability to produce stable laser light sources suitable for industrial production is quite limited.
Its physical principles can be summarized as follows:
a) The beam emitted by the laser is absorbed by the pollution layer on the surface to be treated.
b) The absorption of large energy forms rapidly expanding plasma (highly ionized unstable gas), generating shock waves.
c) The shock wave causes the contaminants to become fragments and be removed.
d) The light pulse width must be short enough to avoid heat accumulation that could damage the surface being treated.
e) Experiments show that when there are oxides on the metal surface, plasma is generated on the metal surface.
Laser rust removal is suitable for small area rust removal, most cleaning high value-added products, such as: precision parts cleaning, aerospace components, military industry, nuclear power industry, parts microprocessing, high-precision cleaning, environmentally friendly cleaning methods, high-precision and cutting-edge industries Cleaning, slide rail cleaning, shipyard parts cleaning, semiconductor processing, rollers, precision parts, welded seams.
Laser rust removal can replace pickling and phosphating cleaning equipment, and can also be used for stainless steel weld bead spot cleaning, titanium alloy cleaning, and welding parts cleaning.
