Laser cleaning The traditional cleaning industry has a variety of cleaning methods, mostly using chemical agents and mechanical methods for cleaning. Laser cleaning can not only be used to clean organic pollutants, but also inorganic substances, including metal rust, metal particles, dust, etc.
The principle of laser cleaning is to use high-frequency and high-energy laser pulses to illuminate the surface of the workpiece. The coating layer can instantly absorb the focused laser energy, causing oil stains, rust spots or coatings on the surface to be instantly peeled off, and the cleaning method of surface adhesions or surface coatings can be effectively removed at high speed. The laser pulse with short action time will not damage the metal substrate under appropriate parameters. Since the laser is non-contact cleaning of the workpiece, it is very safe to clean the precision workpiece or its fine parts, ensuring its accuracy. Therefore, laser cleaning has unique advantages in the cleaning industry.
So, what fields are laser cleaners actually used in?
1. Laser cleaning machines are used for cleaning building exterior walls
Laser cleaning machines are used to clean dark spots and pigmentation on various stone materials such as buildings and stone tablets, which is very effective in protecting ancient buildings and restoring their appearance. The cleaning problem of modern skyscraper exterior walls has become increasingly prominent. Laser cleaning machines provide a good solution for cleaning the exterior walls of buildings through optical fibers up to 70 meters long. It can effectively clean various contaminants on various stone, metal and glass, and the efficiency is many times higher than that of conventional cleaning.
2. Laser cleaning machines are used to remove old aircraft paint
The surface of the aircraft needs to be repainted after a certain period of time. Note that the original old paint needs to be completely removed before painting. The traditional mechanical paint removal method can easily cause damage to the metal surface of the aircraft, which brings hidden dangers to safe flight.
3. Laser cleaning machines are used for mold cleaning
The traditional cleaning methods of mold cleaning include sandblasting, ultrasonic or carbon dioxide cleaning, etc. The traditional cleaning is to use chemical solvents, hot topic, and then cool and then clean, which takes a long time and damages the accuracy of the original mold. Using a laser cleaner to clean the mold is convenient to use, does not produce toxic gases, and does not affect the safety of the working environment; saves time, avoids mold damage, and saves raw materials.
4. Laser cleaning machines are used for precise deester cleaning in the precision machinery industry
The traditional cleaning method is a chemical method, with chemical residues. The use of a laser cleaner can completely remove esters and mineral oils. It is non-contact and does not damage the surface of the parts.
5. Laser cleaning machines are used for cleaning in the electronics industry
The electronics industry requires high-precision decontamination, using laser cleaners to remove oxides. Laser cleaners are non-contact, do not damage the pins, and are highly efficient. A pin only needs to be irradiated with a laser once to completely remove oxides to ensure the best electrical contact.
Laser cleaning technology is widely used in weapon maintenance to remove rust and contaminants efficiently and quickly, and can select the removal site to realize cleaning automation. The cleaning cleanliness of laser cleaning machine is higher than that of chemical cleaning process, and there is almost no damage to the surface of the object. Parameters can be set to form a dense oxide protective film or metal molten layer on the surface of the metal object to improve surface strength and corrosion resistance.
