Laser cleaning: laser cleaning and rust removal application industry

Views: 0     Author: hu     Publish Time: 2021-08-14      Origin: dapeng

Laser cleaning and rust removal uses high-frequency and high-energy laser pulses to irradiate the surface of the workpiece. The coating layer can instantly absorb the focused laser energy, so that the oil stains, rust spots or coatings on the surface can be evaporated or peeled instantly, and the surface attachments or surface coatings can be effectively removed at a high speed. The cleaning method of the layer, and the laser pulse with a short action time will not damage the metal substrate under the appropriate parameters.

Laser cleaning equipment is a new generation of high-tech products for surface cleaning. Easy to install, operate and automate. The operation is simple, the power is turned on, and the device is turned on, that is, no chemical reagents, no media, no dust, no water, automatic focus, surface cleaning, and high cleanliness of the surface.

1. Mold cleaning:

Traditional cleaning methods include sandblasting, ultrasonic or carbon dioxide cleaning, etc., but these methods usually have to be moved to the cleaning equipment for cleaning after the high-heat mold has been cooled for several hours. The cleaning takes a long time and easily damages the accuracy of the mold. , Chemical solvents and noise will also cause safety and environmental issues. Using the laser cleaning method, because the laser can be transmitted by optical fiber, it is flexible in use; because the laser cleaning method can be connected to the optical fiber, the light guide can be cleaned to the dead corner of the mold or the part that is not easy to clean, so it is convenient to use; No gasification, so no toxic gas will be produced, which will affect the safety of the working environment. The technology of laser cleaning tire molds has been widely adopted in the tire industry in Europe and the United States. Although the initial investment cost is relatively high, the benefits of saving standby time, avoiding mold damage, working safety and saving raw materials can be quickly recovered.

2. Cleaning of weapons and equipment:

Laser cleaning technology is widely used in weapon maintenance. The laser cleaning system can remove rust and pollutants efficiently and quickly, and can select the removal part to realize the automation of cleaning. Using laser cleaning, not only the cleanliness is higher than the chemical cleaning process, but also almost no damage to the surface of the object. The waste material removed by the laser basically does not pollute the environment, and it can be operated remotely, effectively reducing the health damage to the operator.

3. Removal of old aircraft paint:

In Europe, laser cleaning systems have long been used in the aviation industry. The surface of the aircraft must be repainted after a certain period of time, but the original old paint needs to be completely removed before painting. The traditional mechanical paint removal method can easily damage the metal surface of the aircraft and bring hidden dangers to safe flight.

4. Cleaning of external walls of buildings:

With the rapid development of our country’s economy, more and more skyscrapers have been built, and the problem of cleaning the exterior walls of buildings has become increasingly prominent. Laser cleaning can effectively clean various contaminants on various stones, metals, and glass, and Many times higher than conventional cleaning efficiency. It can also remove black spots and stains on various stones of buildings.

5. Cleaning in the electronics industry

The electronics industry uses lasers to remove oxides: The electronics industry requires high-precision decontamination, and lasers are particularly suitable for oxide removal. Before the circuit board is soldered, the component pins must be thoroughly deoxidized to ensure the best electrical contact, and the pins must not be damaged during the decontamination process. Laser cleaning can meet the requirements of use, and the efficiency is very high, a stitch only needs to be irradiated with the laser once.

6. Precise deesterification cleaning in the precision machinery industry:

The precision machinery industry often needs to remove the esters and mineral oils used for lubrication and corrosion resistance on the parts, usually by chemical methods, and chemical cleaning often still has residues. Laser deesterification can completely remove esters and mineral oil without damaging the surface of the part. The removal of pollutants is accomplished by shock waves, and the explosive gasification of a thin layer of oxide on the surface of the parts forms a shock wave, which results in the removal of dirt instead of mechanical interaction. The material is thoroughly deesterified and used for the cleaning of mechanical parts in the aerospace industry. Laser cleaning can also be used to remove oil and ester in the processing of mechanical parts.

7. Pipeline cleaning in nuclear power plant reactor:

The laser cleaning system is also used in the cleaning of pipelines in nuclear power plant reactors. It uses optical fibers to introduce high-power laser beams into the reactor to directly remove radioactive dust, and the cleaned materials are easy to clean. And because it is operated remotely, the safety of the staff can be ensured.
