Metal rust is a chemical reaction, also called metal corrosion, which refers to the process of destruction and deterioration caused by chemical or electrochemical reactions between the metal and its environment. Turn the metal into an oxidized (ion) state. It is its thermodynamic instability, that is, the metal and itself are in a state of higher free energy than some compounds (such as oxides and hydroxides), so that elemental metal compounds will occur when the free energy conditions are available. This will significantly reduce the strength, plasticity, toughness and other mechanical properties of metal materials, destroy the geometric shape of metal components, deteriorate electrical and optical physical properties, and shorten the service life of the equipment. Under normal circumstances, the greater the energy consumed when a metal is refined, the faster the metal will corrode.
Iron rust is caused by the reaction with oxygen and water in humid air, and is related to oxygen and water. If both are available at the same time, it is easy to rust. The most common rust phenomenon is that iron products have been exposed to the air for a long time and have an oxidation reaction with oxygen, or they are corroded by oxygen in the water to become oxides.
When copper encounters carbon dioxide and oxygen in a humid environment, green patina will be produced. The main component of patina is basic copper carbonate.
When lead metal is exposed to oxygen, water vapor and carbon dioxide in the air, its surface will quickly oxidize to form lead alkali carbonates (lead has a variety of alkali carbonates), and the surface of this layer will be very exposed to water. Quickly fall off and continue to oxidize.
Zinc metal is more active, and there are many kinds of rust. For example, heated zinc will quickly react with oxygen to form zinc oxide. In humid air, it will quickly form zinc hydroxide. Only in a low humidity environment will it be slow. Alkaline carbonate is formed, and the zinc on the surface of the waste dry battery often reacts with the ammonium chloride paste inside the battery to produce something with complex composition.
Do you think aluminum will not rust if it is protected by a dense oxide film? A long-used aluminum pressure cooker has white aluminum rust on the inside and outside. The difference is that the aluminum rust inside the pressure cooker is layered, and the aluminum rust on the bottom of the pressure cooker is grain-shaped.
Laser rust removal machine is a type of manual laser cleaning machine composed of fiber laser generator, laser rust removal gun, and laser cleaning system, which uses pulsed laser or CW (Continuous Wave) laser to irradiate the metal surface, and the coating layer can instantly absorb the energy of the focused laser, so that the rust, coating or oil on the surface can be stripped instantly or evaporation, high-speed and effective removal of the coating attached to the metal surface, laser rust removal, basically will not damage the metal substrate. Laser rust removal machine is also known as laser rust removal tool, laser rust cleaning machine, laser rust cleaner, laser rust remover, laser rust removing tool, laser rust removing machine, laser descaler machine.
Laser rust remover can solve problems that cannot be done by traditional rust removal methods. Even if it is special-shaped metal parts, laser rust cleaning machine can also perform rust removal operations. In short, wherever laser can be irradiated, the rust, oil stain, paint layer, or oxide layer on the surface can be removed.
Laser rust removal machine transmits the laser beam generated by the laser generator to the laser rust removal gun through the laser cleaning system, and scans the metal surface by the laser beam from the laser rust removal gun for rust cleaning.
Laser rust removal can be understood as a deeper level of laser cleaning. There are two main methods of laser rust removing. One method is to use clean substrates and surface attachments that have very different absorption coefficients at a certain wavelength of laser energy. Most of the laser energy irradiated on the surface is absorbed by the surface attachment, which makes it heated or evaporated, or rapidly expanded by the vapor flow formed on the surface and driven away from the surface of the object to achieve the purpose of cleaning. However, since the laser light absorbs very little energy at this wavelength, the substrate is not damaged. Selecting the appropriate wavelength and controlling the laser energy is the key to achieving safe and efficient cleaning.
The other is a laser rust remover for cleaning substrates and surface attachments. The laser energy absorption coefficient is not much different, or the substrate is sensitive to the acid vapor formed by the coating heat, or the coating will produce toxic substances after heating. This method typically uses a high-power, high-repetition-rate pulsed laser to strike the cleaned surface and convert part of the beam into sound waves. The returning portion of the sound wave hits the underlying hard surface, interfering with the incident sound wave produced by the laser, producing a high-energy wave that causes the coating to explode slightly. The coating is milled, pressed into powder, and then removed with a vacuum pump without damaging the underlying substrate.
What Is Laser Rust Removal Gun?
Laser rust removal gun includes a gun shell, a galvanometer scanning component and an iris component. The laser generated by the laser generator is scanned by the galvanometer to form a linear light spot, which is emitted from the square light exit hole of the iris to the object to be cleaned. , the whole constitutes an optical output channel. The adjusting diaphragm can slide along the length of the light-emitting hole on the fixed diaphragm, and then change the light-emitting length of the light-emitting hole to make it consistent with the size of the linear light spot, so as to prevent the returning light from entering the gun shell during the cleaning process. The laser rust removal gun has the advantages of simple structure, convenient use, and can process any high-reflection profiles. It can be adapted to different types of laser generators. At the same time, the contact between the optical components in the laser rust cleaning gun and the outside world is closed to avoid pollution.
In addition to being used for handheld laser cleaning, laser rust removal guns can also be installed on moving mechanical devices (such as robots, manipulators, and CNC machines.), and the mechanical device automatically completes the preset motion trajectory. Its advantages are high precision, large-scale operation, and low technical requirements and labor intensity for operators.

The price of a laser rush removal machine is different from the pricing methods of traditional cleaning such as detergents. Compared with the attributes of cleaning agents as consumables, laser rust cleaning machines can be used repeatedly. As a laser equipment, its price mainly depends on different configurations. For example, if a laser generator with higher power is used, the price will definitely be higher.
The price of 1000W portable laser rust remover starts from $8800. The price range of 1500W handheld laser rust removing machine is from $9800. The minimum cost of 2000W high power laser rust removal machine is $12,800. Of course, the price of an automatic laser rust cleaning machine with CNC controller or robot will be higher.
Even if the configuration is similar, the costs from different manufacturers are not the same. Because the cost not only involves configuration, but also includes shipping, brand, after-sales service, and other factors.

I used it to remove rust from cast iron mold. Took one minute to bring the inside to a shining finish. This was my second order with this seller both times were great experiences. Im super pleased and would definitely recommend and purchase anything from this vendor.
