How to Remove Rust And Paint Laser Cleaning?

Laser cleaning represents a non-broken and non-ententacular cleaning method. It allows laser beams to control rust, paint, oxides, and other pollutants on the surface of most materials. Base material. Therefore, the laser cleaning machine is gradually replacing the traditional cleaning method and becoming the first choice for surface cleaning technology. How does laser cleaning remove rust and paint? Is it effective for metal surface cleaning? In this article, we will explore the use of laser cleaning technology to clean, including its operating principles and uses.

The working principle of laser cleaning

Laser cleaning uses the process of laser ablation. Provide high-energy pulses in a short time, vaporize oil, oxide, paint, and other residues, and eliminate them. After cleaning, the metal surface is intact.
Laser cleaning technology works by sending nanosecond-length laser pulses to the surface of the material. The specific working process is to align the surface of high-power laser beams on rust, paint, or coating. When it interacts with pollutants absorbing laser, pollutants or coating particles will become gas. The pressure of interaction will Make pollutant particles from the surface and easily remove them. Laser cleaning technology is very suitable for specific areas of workpieces, and clean and welded surfaces can still be left after cleaning. With the correct laser settings and equipment, the cleaning ability of laser cleaning will be unparalleled, and it can be repeatedly washed until the expected effect.
At the same time, laser cleaning technology is a “green” cleaning method that does not need to use any chemical reagent or cleaning solution. The cleaning waste is solid powder, with a small volume, easy to store, and recycled. Avoiding the problem of polluting the environment with chemical cleaning methods, makes it an ideal solution to replace traditional cleaning methods.
Note that each material has different characteristics and different molecular keys. In other words, each material has a specific ablation threshold. To successfully remove the coating from a specific material, the energy of the laser beam transmission must be higher than the obscured threshold of the specific material.

Is laser cleaning really effective?

Is laser cleaning really effective? Many facts have proved that laser cleaning technology is one of the most feasible surface cleaning methods. The laser beam can reach difficult parts that cannot be reached by traditional methods, and clean up any details in the surface and welds. In addition, laser cleaning can remove various impurities on the surface to achieve the cleanliness that traditional methods cannot achieve, there is no need to worry about the safety of operators. Of course, laser cleaning is also used in heavy industries such as aerospace and shipbuilding, and is the best alternative method for traditional and bladder and chemistry. So choosing laser cleaning is a wise choice.
The concept of laser cleaning machines has gradually touched all industries. Traditional industrial cleaning is time-consuming and laborious, and the removal of oxides alone may involve various hazardous chemicals. Today, the laser is changing this. Using laser cleaning can omit all chemistry processes, which greatly benefits the industry and the environment.

Use of laser cleaning

Laser cleaning is an ideal choice for various applications. This process can be applied to any metal, the most typical are steel, aluminum, and copper. Laser cleaning can also be used for rust removal, oxide removal, mold cleaning, and surface treatment. It is roughly divided into the following:

Surface cleaning

Generally, surface cleaning is the widest cleansing activity of laser cleaning machines, such as rust removal, deoxidation, dehydration, cleaning coating, and weld cleaning, all of which are types of cleaning.

Rust removal: Metals that are used for a long time or unused will produce rust. Therefore, most heavy metals and manufacturing industries need to remove rods or dehydration frequently. The laser cleaning speed is affected by the rust level, and high -power laser can speed up the cleaning process.
Desequent: Laser cleaning technology can remove all types of oxides on the metal surface. Used for coating and adhesive surface treatment, thereby improving the adhesion of the coating in the process.
Coating removal: Laser cleaning can remove top coatings and all pollutants without damaging the underlying coating. It is often used to make metal pre-processing. At the same time, this process provides slight roughness at the top layer, thereby increasing the adhesion of the glue or sealing agent.
Skin: Usually, in the process of manufacturing and maintenance of mechanical parts, water/dirt and fat will accumulate. This mixture forms sediments on the surface of the material and affects its function. Laser cleaning technology can easily remove dirt and clean the materials.
Clean weld: Welding will leave surface sediments. You need to remove these sediments for the final decoration of the product. Therefore, the laser cleaning machine plays an important role in removing the welding joint and the cleaning unit.

Mold cleaning

Cleaning mold is a very difficult task. Using a laser cleaning machine, you can easily reach every corner of the mold and remove any impurities in it. Even after cleaning, the chemical composition of the mold can remain unchanged, and it will not affect the mold itself.
This type of cleaning process is widely used in the food and packaging industry. Because most foods need to be packaged in strict and clean environments. Therefore, the best choice for quickly and accurately cleaning the container is to use laser cleaning technology.

Repair recovery

Because there is no physical contact between the cleaning object and the laser equipment, laser cleaning can be used to deal with fragile materials in the repair application. Compared with more traditional technology, laser cleaning can directly adjust the diameter of the laser beam to handle different sizes. Laser cleaning is often used in stone maintenance to remove stone shells. Except for aesthetics that have a pleasant effect, laser cleaning has no adverse effects on stone.

Non-destructive test

Non-destructive testing, also known as non-destructive testing, is a technique commonly used in the technology industry. It is used to evaluate the properties of a material, component, or system without causing any damage to the underlying material. Therefore, if non-destructive testing is required, laser cleaning would be a perfect solution.

Selective paint

In the automotive and aerospace industries, it is sometimes necessary to remove the top coat of paint while preserving the primer. The primer remains intact because the laser has no mechanical, chemical, or thermal effect on it, which guarantees the maintenance of the corrosion resistance of the primer. This property comes in handy when some branding errors need to be corrected and only part of the metal surface needs to be cleaned or repainted.

Precautions during laser cleaning

Although laser cleaning technology is considered one of the safest ways of cleaning, improper operation will still cause harm to you or other people. Do not use laser cleaning:

The operator does not bring a goggle.
Laser directly contacts the skin or body.
There is no specified sign to warn the laser cleaning when the machine is working.
Operate near the individual that is vulnerable to injury.
Do anything more than the expected purpose when using the machine.
There is no appropriate air filtration when the machine is working.

Like other high-pressure items, you need to receive appropriate training to avoid the danger caused by improper operations. This is the reason why AccTek Laser will provide you with security training when buying a laser solution. You will understand the entire process of security operations and maintenance of the machine, and how to protect your applications and employees’ security.

Summarize

Laser cleaning technology can overcome many problems facing rust removal and other industrial cleaning applications. In addition to cleaning capabilities, there are many other benefits of laser technology: easy to operate and safe, it does not need to clean the machine, the operating cost and maintenance costs are relatively low, and it is friendly to the environment. It is necessary to have a laser cleaning machine for regular enterprises.
